Topical Collection Information

Dear Colleagues,

The management of construction projects can be a very complicated process, especially when there are too many construction companies and various parties involved. The progress of information technology, as well as decision support methods, in the fields of cost planning and time and risk management systematically pushes the limits of possibilities in the construction industry and the range of impact on the entire construction industry.

The implementation of the latest solutions is necessary for construction companies to achieve success in the industry and remain competitive in the global market. As advanced technologies developed, the integration of technologies has been adopted for promoting new technologies and methods in construction in recent years, such as building information modeling (BIM), simulation-based methods, or mathematical methods supporting decision-making.

It is necessary to use new trends and ideas in many areas of construction project management, such as costing, scheduling, safety at the construction site, and human resource management in various types of construction projects in all phases.

The aim of this Topical Collection is to provide a platform to explore the state-of-the-art knowledge, practical implementation, and cutting-edge innovations in the area of construction management in construction industry.

Survey and theoretical articles, as well as application papers, are welcome.

Effective Construction Site Layout Planning (CSLP) ensures the organized placement and sizing of temporary facilities, enhancing workflow and logistical efficiency. Poorly planned layouts, however, can increase material handling times, create bottlenecks, and reduce productivity, ultimately leading to higher costs. The main objective of this study is to introduce a BIM-based hybrid framework for CSLP that integrates Systematic Layout Planning (SLP) with a Genetic Algorithm (GA), developed through a Design Science Research approach. This Construction Site Optimization Framework (CSOF) addresses CSLP as a multi-objective optimization problem, prioritizing efficient positioning of facilities while accounting for workflow intensity, safety, and manager preferences. The framework’s continuous-space modeling supports a realistic approach, moving beyond fixed-location models. Exploratory case studies demonstrated CSOF’s effectiveness, achieving 30.79% to 40.98% reductions in non-value-adding travel distances and adaptability across varied site conditions. In this way, this research provides a decision-support tool that balances automation with decision-maker input, enhancing layout efficiency and operational flexibility in construction site management.

The construction industry has yet to reach significant levels of digitalisation compared to other sectors, which could enhance its processes. Recent building failures globally have eroded public trust in the industry, highlighting issues of compliance. This has prompted the introduction of building regulations, where digitalisation is expected to play a key role in supporting compliance. This paper aims to assess the impact of digitalisation on two key stakeholder groups within the construction industry—designers and builders—across various organisational sizes. A questionnaire survey was conducted with designers and builders in Australia, focusing on information technology (IT) infrastructure, digital capability, training, and research and development. Descriptive statistics were analysed and cross-analyses between designers and builders, as well as across different organisation sizes, were conducted using the Mann–Whitney U and Kruskal–Wallis H tests. The findings revealed clear differences between designers and builders regarding digitalisation across IT infrastructure, digital capability, training, and R&D. For example, builders primarily rely on cloud storage while designers use a combination of local and cloud storage. Designers allocate a higher percentage of their turnover to IT, whereas builders are twice as likely as designers to lack structured training for digital skills. When organisation size was considered independently, similarities were observed across sizes. These results provide insight into the current digitalisation landscape in construction, offering a foundation to support the adoption of future industry regulations. Full article

The Construction Cost Index (CCI) is an important tool that is widely used in construction cost management to monitor cost fluctuations over time. Numerous studies have been conducted on CCI development and forecasting models, including time series, artificial intelligence, machine learning, and hybrid models. Therefore, this study seeks to reveal the complexity of CCI forecasting and identify the leading indicators, trends, and techniques for CCI prediction. A bibliometric analysis was conducted to explore the landscape in the CCI literature, focusing on co-occurrence, co-authorship, and citation analysis. These analyses revealed the frequent keywords, the most cited authors and documents, and the most productive countries. The research topics and clusters in the CCI forecasting process were presented, and directions for future research were suggested to enhance the prediction models. A case study was conducted to demonstrate the practical application of a forecasting model to validate its prediction reliability. Furthermore, this study emphasizes the need to integrate advanced technologies and sustainable practices into future CCI forecasting models. The findings are useful in enhancing the knowledge of CCI prediction techniques and serve as a base for future research in construction cost estimation. Full article

Lifts, or elevators, are transportation facilities that are indispensable for countless end users in high-rise buildings. They require proper maintenance to ensure safe operation. In addition to technological applications, effective management and legislative controls play a crucial role in ensuring lift safety. Given the limited understanding of an optimal regulatory model for governing lift maintenance, a cross-discipline comparative study was conducted to examine lift maintenance regulations in regions with different legal systems. Following a systematic and comparative review approach, this study focused on regulatory controls across civil and common law jurisdictions, specifically Beijing, Hong Kong, and London. Relevant statutes and publications were searched from engineering, law and management databases, which included Scopus, JSTOR, Lexis+, Lexis China, Lexis Advance Hong Kong, and Westlaw Asia. Through scrutinizing the retrieved documents, key features of the regulations were identified and compared in terms of lift classifications, types and frequencies of mandatory maintenance works, qualifications for authorized parties, and legal liabilities for non-compliance. Validated by industry experts, the results reveal both similarities and differences in the regulations among the three jurisdictions. While these findings serve as valuable references for policymakers in formulating optimal legislative controls to enhance lift safety in the future, further research could expand the scope of this study to examine the regulations in other regions and investigate the effectiveness of existing statutory controls on lift maintenance.

The construction industry has been slow to implement safe working conditions, even though it could reduce the risks and dangers that the industry’s operations pose to human health and safety. More research and development in this area is clearly needed to increase the acceptance of safety in the execution of engineering projects, as previous study has demonstrated. Therefore, this study will analyse safe working conditions in construction-related professions in order to determine the focal area of previous studies. However, there has not been much effort put into mapping international studies on safe working environments in the construction industry. This research evaluates safety for the construction industry in order to discover new research trends. This indicates the ongoing challenges in the sector. For this study, comprehensive bibliometric methodology was applied, and data were extracted from the Scopus database. Using keywords like “safe”, “working condition”, “construction industry” or “built environment”, “health and safety”, and “technology”, publications from the database were extracted. Based on the collected bibliographic information, a co-authorship and co-occurrence map was created using VOSviewer. Research on occupational health and safety in the building industry, safety management and risk factors in the construction industry, ethical considerations in human experimentation, and safety and work environment revealed an emerging trend in safe working conditions in the construction industry.

The selection of an appropriate construction method stands as a pivotal decision in ensuring the success of any building project. This paper undertakes a comprehensive comparative analysis of cost and timeline implications between the top-down and bottom-up construction methodologies. The research focuses on ten distinct underground structure models, each characterized by varying depths and base areas. Through rigorous design and analysis, the cost and projected duration for each model are meticulously evaluated under the lens of both top-down and bottom-up construction techniques. The findings reveal that while the bottom-up approach emerges as the most cost-effective alternative at a depth of 8 m, the top-down method exhibits superior cost efficiency with increasing depth. Interestingly, alterations in the structure’s base area exert a minimal influence on the cost differentials between the two methodologies. Moreover, the top-down construction method consistently outshines its counterpart in terms of project duration across all ten models examined, with the percentage increase in base area yielding insignificant impacts on project timeline discrepancies. This study furnishes construction project managers with invaluable insights to navigate the complexities of method selection. By judiciously considering parameters such as project scale, depth, and base area, managers can strategically optimize both cost and timeline outcomes, thereby facilitating the seamless execution of construction projects.

Public–Private Partnerships have been implemented globally as a key procurement strategy for addressing the issue of funding gaps amidst the immense pressure to deliver new major infrastructure projects. However, in current practice, procurement selection is applied to the entire bundle of project activities. This often leads to unduly large bundles of externalized project activities that create unduly large PPP contracts and attempt to transfer too much risk. To address this gap, this paper presents the development and testing of an implementable model that embodies a range of microeconomic theories—namely, transaction cost and resource-based theories—and property rights theory. This paper presents the first empirical testing of this model based on two road and two health projects, using competition as an independent measure of the validity of the recommended procurement strategy. The results provide compelling evidence that a rigorous application of the model will enable a substantial improvement of existing procurement approaches, such as identifying the most suitable bundle to be procured using a PPP approach.

With the continuous improvement of construction management standards, thorough investigation into various management objectives becomes crucial. To address the current gaps in project management concerning time, cost, safety, and carbon emissions interrelationships, this study adopts the multi-objective optimization (MOP) theory and makes the following contributions: (1) proposes an innovative carbon emission model, which enhances the cost model by incorporating carbon cost factors, and establishes a MOP model covering time–cost–safety–carbon emissions; (2) validates the effectiveness of the proposed model and the feasibility of algorithms through empirical research and algorithm comparison analysis—the research demonstrates that NSGA-III exhibits significant advantages in solving MOP problems of this scale; (3) applies the entropy-weighted VIKOR method to objectively analyze the solution set obtained by NSGA-III for optimal solution selection. This study provides practical management tools for project managers and offers significant insights for researchers in construction management regarding multi-objective problem-solving and algorithm selection.

With the development of new construction technology, increasing attention is being paid to 3D printing due to its construction efficiency as well as its sustainability. Numerous researchers have determined its benefits in cost reduction, resource savings, safety assurance, etc. Although various advantages have been identified, there are limitations and challenges in technology implementation. Especially since it is a new construction method, 3D printing construction projects will have a very different supply chain compared to traditional projects. As part of a research programme investigating the 3D printing construction supply chain in a New Zealand context, this study systematically analysed the research about 3D printing adoption and supply chain challenges in the construction sector. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was adopted as the guideline for literature selection. PRISMA is designed to assist researchers in reporting the review research focus and methodology, and examining the findings from published literature. NVivo was then adopted to code and analyse the selected publications to gather the data necessary for our study. The literature was analysed from the perspectives of the research focus, research methods, and findings. Studies about 3D printing implementation, benefits and barriers, as well as its significance are also analysed. As a result, this research found existing research gaps, including the fragmented situation of management-related research in the 3D printing construction sector, insufficient research in top management for 3D printing construction implementation, and changes to supply chain management practices in 3D printing construction projects. A decision support system demo for supply chain management is drafted in this paper, which requires further study. The research outcome highlighted the existing studies in 3D printing construction implementation and supply chain, and initiated a research topic on supply chain decision making. The result contributes to the theoretical and practical development of 3D printing technology in the construction industry. This review paper also inspires future studies on supply chain frameworks and theoretical models. Full article

Cost estimation is the process of creating cost forecasts by quantitative determination and pricing of the necessary resources for a project’s implementation. This process is iterative, where estimates are regularly updated based on the available information. Studying the relationship between the costs of construction projects is crucial for establishing reliable practices of cost estimation and management. Variability in construction costs can significantly impact investors’ or clients’ decisions. Greater coherence and confirmed relationships between construction costs and factors influencing them can assist investors, developers, and contractors in making informed decisions and ensuring effective cost management. Therefore, the aim of this article is to identify the factors shaping the costs of facade systems of public utility buildings and to examine the mutual influences and dependencies that occur between these factors. The factors were selected based on an analysis of project documentation, and then their assessment was made through expert opinions. The DEMATEL method was used to investigate the mutual relationships and dependencies between the factors as one of the tools of multi-criteria analysis. Through the analysis, it can be pointed out that factors such as the height of the building, the type of facade analyzed, and the level of complexity of the facade have the greatest impact on the cost of facade systems. Moreover, the type of facade analyzed and the number of floors are the factors showing the greatest direct influence on the other factors of the cost of facade systems. The identification and prioritization of factors carried out by the authors provide a basis for future research, which are models that support the prediction of the cost of making facade systems.

Despite the growing rich and fragmented literature focusing on quality assurance (QA) and Industry 4.0, the implementation of associated individual digital technologies has not been fully evaluated and synthesised to achieve adequate QA in the construction industry; hence, it has received limited focus. This study, thus, aimed to organise, evaluate, and synthesise the current literature on individual digital technology applications in QA in the construction industry and propose future research directions. A literature review approach was adopted for this study along with Deming’s cycle framework to address four research questions: (1) What is the status of the state-of-the-art in the literature? (2) What digital technologies have been applied for QA in the construction industry? (3) Which areas in QA processes have experienced digital technology applications, and what are the applications? (4) What are the limitations of the existing studies and future research directions of digital technologies for QA in the construction industry? The findings showed an increasing trend of research on digital technology for QA in construction since 2017. This cuts across 23 countries with six different research methods published across 18 different publication sources. Four categories of digital technologies were revealed to have been adopted for QA in construction based on the functionality of the technologies: data collection technologies, decision-oriented technologies, collaborative technologies, and transparency and security-related technologies. Evaluation with Deming’s cycle framework revealed that digital technologies have a high level of application at the “do” phase, improving the quality management process during construction towards achieving pre-stated quality requirements. This includes mostly collaborative technologies, consisting of BIM technologies. Limitations of the existing studies were further identified, and this led to five research directions: interoperability of technology development, integrated digital technologies for QA of prefabricated and modular construction, integrated digital technologies for QA of cross-border construction logistics and supply chain, digital innovation for sustainable QA, and moving beyond the technical solution. The study showed a significant contribution to both academia and the industry in the built environment. Full article

Improper understanding of complexity can be a leading factor in the failure of construction projects. This study aims to provide a better understanding of the complexity of construction projects. For this purpose, this study uses the systematic literature review (SLR) approach to review the related literature and propose a definition for complexity and the criteria that affect the degree of complexity in construction. The results of analyzing 49 studies from the literature showed that, generally, complexity is understood in three ways: the meaning of the word “complexity”, system and organizational complexity, and project complexity. Within these three types of definitions, it was found that “interdependency” and “multiple parts/parties” are the most frequently used keywords. The results also showed that another look at the current lingual definition of complexity is needed. Regarding the criteria, the results showed that the “number of stakeholders”, “scope and project objectives”, and “management structure” are the most important criteria to assess construction project complexity. Accordingly, this study provides a set of recommendations and strategies to help manage complexity in construction projects. Full article

This study aims to explore the relationship between leader and follower psychological capital (PC) congruence, intrinsic safety motivation (ISM), and safety behavior (SB). The construction industry is one of the most dangerous industries, and most safety accidents are determined by human behavior. Exploring the factors influencing construction workers’ SB is important for improving construction safety. This study collected 242 paired questionnaires from frontline construction workers and crew leaders in China. The SPSS 22.0 software and PROCESS program were used for analysis, the empirical study was conducted using polynomial regression and response surface analysis, and the block variable method was used to test for mediating effects. The findings show that (a) the level of follower SB is determined by the degree of leader–follower PC congruence; (b) when leader–follower PC was congruent, the impact of both high PCs on follower SB was enhanced compared to each low PC; (c) when leader–follower PC was incongruent, the impact of follower PC (FPC) above leader PC (LPC) was better on follower SB compared to FPC below LPC; (d) the relationship between leader–follower PC congruence and follower SB was mediated by ISM. The promotion of SB should focus on the fit between leaders and followers in addition to the PC of the followers themselves. This study contributes to workgroup safety in the construction industry by improving the fit between workgroup leaders and members, promoting ISM, and thus improving their safety performance.

Agile ways of working have garnered recognition for their capacity to drive innovation, placing a strong emphasis on adaptability to change and a user-centric approach. Inspired by these proven principles, the authors envision that applying scaled agile—an extension of agile methodologies—can serve as a catalyst for revolutionary transformations in how buildings are redesigned, refurbished, and operated, ushering in a new era of practices within the industry. This paper conducts an in-depth literature review to explore the application of agile ways of working in building adaptation projects. Drawing on insights from the literature review and expert validations, the authors propose the development of the Agile Building Adaptation (AgiBuild) framework, delineating its core components and outlining the probable implementation process. Notably, the framework’s successful integration hinges on crucial factors, including effective leadership influence and comprehensive training.

BIM has become an intrinsic tool in managing building projects due to its ability to comprehensively represent information in digital form. However, using BIM as an information exchange tool is still in its infancy, particularly with regard to construction progress monitoring beyond time schedule information. The current study focuses on the development of an automated progress monitoring framework based on an IFC-based BIM and provides an extensive methodology based on a structured task-based approach in accordance with the latest IFC4.x schema in four stages. The first stage creates the appropriate IFC entities, which are then enriched with their values in the second stage. The third stage integrates the actual progress information, which requires regular updating from the construction site. Finally, the fourth stage enables the retrieval of progress information, which is then reported in a user-friendly format along with the estimation of additional progress indicators. The proposed method successfully integrated the progress information into their IFC-based BIM models, demonstrating its practical use for monitoring construction progress. In the end, a web-based application was also developed that made use of progress information stored within the standardized hierarchy of the updated IFC-based BIM to facilitate efficient reporting.

The high number of annual safety accidents and casualties reflects the problems of slow detection of safety accidents and untimely early warnings in current construction safety management, and China urgently needs new methods and technologies to improve the safety management efficiency of the construction industry. However, there are fewer achievements in the use of new technologies for intelligent construction safety management, and most of the research focuses on intrusion detection and specific event alarms, which cannot be well implemented for systematic early warning functions. Based on the existing research and the characteristics of early warning scenarios, this study introduces the convolutional neural network (CNN) to build a video image recognition and classification model to give early safety warnings for intrusion behavior in hazard areas of construction and demonstrates the warning effect and accuracy with practical cases. First, it clarifies the early warning demand information, such as the attributes of construction personnel and hazard areas. Then, the construction model is realized by multi-scale hierarchical feature extraction mapping, the Softmax classification function, and the argmax function. Finally, from the empirical analysis, it can be seen that an early safety warning based on the CNN model has an accurate ability to identify the intrusion behavior of construction site personnel, which can reduce the probability of construction safety accidents to a certain extent, and provide enlightenment for further realization of intelligent construction sites.

Many studies have developed technologies intended to automate the process toward improving sustainability and achieving a circular economy in the construction industry. Despite some research works that have been recently conducted to help construction agents in the management of construction and demolition waste (CDW), developing new CDW monitoring and traceability tools—through a collaborative and integrative approach—is still an urgent challenge. This paper developed a hybrid mobile app for the real-time traceability of construction waste generation and management, where agents involved in CDW management can work together and trace the generation and management of waste. For this, a research method was developed following three stages: (1) planning and design, including identification of the information to be incorporated in the app and the output data; (2) development of the app; and (3) app testing by several construction agents, stressing the benefits and limitations. The developed app allows not only estimating but also tracing the amount of CDW generated in a construction project, ensuring the correct management and control of the waste. In addition, it promotes collaborative work, as the agents involved in CDW management, i.e., construction companies, site managers, truck drivers, waste managers, and management plants, can work together and see in real-time the management of the waste.

Individuals and their leadership competencies have been the sole focus of project leadership research, rather than the project leadership’s behaviour and functions in project and organisational settings. As a result, this study investigates the project leadership functions and behaviours required for various project and organisational situations in order to propose a project leadership model that will be effective in all project and organisational situations. The model that was developed and tested in this study theorised about the project leadership function that project leaders are expected to perform as a result of their positions. It also described how project leaders could tailor their leadership functions and behaviours to address issues related to positions, organisational situations, and project situations. Three hypotheses were developed and tested using structural equation modelling to validate the model. The model’s perceptive power demonstrates adequate validity. The model’s validity implies that there are appropriate project leadership functions for different leadership levels and circumstances. The model’s validity also implies that each project leadership behaviour has its own value, as conditions and necessities dictate. The study assumes that a project leader can embrace project leadership by combining a few different project leadership functions and behaviours. Full article

A continuous evaluation of the stakeholder management process can be achieved using definitive key performance indicators (KPIs). An exhaustive literature survey in this direction provided a set of 26 indicators assessed through a questionnaire survey for their possible implications on the stakeholder management process. The survey was conducted among 55 respondents with experience in using building information modeling (BIM) in mega-construction projects. The data were initially analyzed through factor analysis to establish six KPIs. Fuzzy synthetic evaluation (FSE) was used to evaluate the index values of the established KPIs to assess their importance levels. The results presented the KPIs in decreasing order of their index values: asset performance (4.27), open innovation (4.04), project O&M expenses (3.97), design process efficiency (3.95), project execution efficiency (3.90), and stakeholder concerns (3.59). The results generated a stakeholder management process assessment framework and model that provides a clear insight into using an indicator in measuring the specific stakeholder management dimension. The findings of this work can provide definite insight amongst planning managers about the stakeholder management process through the posited indicators. Further, they can adopt measures to improve the stakeholder management process in their respective projects. Full article

Environmental concerns over the effects of construction sector activities necessitate meaningful measures to be taken. Despite worldwide increases in the uptake of environmental management systems (EMS), implementation of EMS across the construction sector of the U.S. remains slow. To date, stakeholder opinions about the uptake of EMS in the construction sector of the U.S. remain unexplored. The purpose of this study is to investigate the views of U.S. stakeholders towards the benefits and barriers of implementing EMS, and how these compare internationally. Underpinned by a positivism philosophy, an online questionnaire survey was used to collect the views of construction professionals (n = 50). Weighted average analysis scores reveal that the benefits of EMS are seen to improve the public perception and credibility of an organization/company and reduce waste levels and are a tool to improve the environmental standards of the U.S.’s construction sector; in contrast, the barriers of EMS are an absence of sub-contractor cooperation and resistance to change in existing company structure and policy, plus the requirement for additional employee training. The potential impact of this work demonstrates not only the role that the U.S. construction sector can play in advancing environmental and sustainability matters using EMS but also the obstacles that need to be addressed to enable their success. Understanding these benefits and barriers at an organizational level could enable them to devise more effective business strategies/policies, where evidence-based practices could be used to support EMS implementation.

It is thought that there is a low level of awareness of key competencies that drive material waste reduction at the construction stage of a project which has led to the low impact of waste minimization in the construction industry. This study, therefore, explores the key competencies for driving waste minimization at the construction stage of projects. Twenty-four (24) key factors that drive CW minimization at the construction stage of projects were derived from a thorough review of existing literature. The research adopted the quantitative approach whereby a questionnaire survey involving 53 construction professionals was conducted. Factor analysis was the statistical tool employed for the analysis of the data gathered. The findings of the study revealed four major competencies that drive CW minimization: Awareness Competency (AC), Managerial Competency (MC), Personnel Ability Competency (PAC), and Communication Competency (CC). The implementation of the key competencies from the findings of the study is highly recommended for the achievement of low waste in building projects. In view of this, it is recommended that government should enact legislative and fiscal measures to instill waste management habits in the construction industry. Several studies have investigated strategies or measures for CW minimization. However, this study focused on the knowledge and skills of construction stakeholders as the main component of waste minimization competencies. Full article

The construction industry has been experiencing many occupational accidents as working on construction sites is dangerous. To reduce the likelihood of accidents, construction companies share the latest construction health and safety news and information on social media. While research studies in recent years have explored the perceptions towards these companies’ social media pages, there are no big data analytic studies conducted on Instagram about construction health and safety. This study aims to consolidate public perceptions of construction health and safety by analyzing Instagram posts. The study adopted a big data analytics approach involving visual, content, user, and sentiment analyses of Instagram posts (n = 17,835). The study adopted the Latent Dirichlet Allocation, a kind of machine learning approach for generative probabilistic topic extraction, and the five most mentioned topics were: (a) training service, (b) team management, (c) training organization, (d) workers’ work and family, and (e) users’ action. Besides, the Jaccard coefficient co-occurrence cluster analysis revealed: (a) the most mentioned collocations were ‘construction safety week’, ‘safety first’, and ‘construction team’, (b) the largest clusters were ‘safety training’, ‘occupational health and safety administration’, and ‘health and safety environment’, (c) the most active users were ‘Parallel Consultancy Ltd.’, ‘Pike Consulting Group’, and ‘Global Training Canada’, and (d) positive sentiment accounted for an overwhelming figure of 85%. The findings inform the industry on public perceptions that help create awareness and develop preventative measures for increased health and safety and decreased incidents. Full article

The performance of the construction industry can be improved by understanding the factors that affect the productivity of its equipment. A hypothetical framework was used to analyze six vital construction equipment parameters to understand how they affect productivity in construction projects. Data collected through a survey of 110 respondents in the construction industry were analyzed using an exploratory factor analysis (EFA) and structural equation modeling (SEM). The final model obtained using SEM consisted of 31 attributes from six construction equipment productivity factors, namely management (MG), materials (MT), human (HM), technical (TN), environmental (EM), and other factors (OT). Construction equipment productivity was found to be significantly influenced by MT and OT in construction projects. This was mainly because of their corresponding subfactors, such as operating life and equipment age, and the occurrence of accidents during construction. Consequently, based on survey feedback from various construction professionals, present gaps in construction equipment productivity were analyzed, and recommendations were made to overcome the main limiting factors under MT and OT. This study identified and quantified the interrelationships between various construction equipment productivity constraints. Therefore, the results can help experts and specialists better comprehend how to overcome delays due to idle time and improve construction equipment productivity. Full article

Offsite construction (OSC) in Southeast Asia is facing many challenges due to the COVID-19 pandemic. Despite its importance, there is scant research on this topic in the region. This study aims to review OSC and identify determinants of success and their correlation with success after the pandemic in the Southeast Asian region. This paper follows a sequential exploratory mixed methodology: (1) reviewing statistical data relevant to construction in four countries, (2) carrying out a configurative literature review and documentary research, (3) eliciting responses from in-depth interviews consisting of two phases, (4) collecting written consultancies, and (5) capturing experts’ opinions in four countries through a questionnaire survey. The study uses three statistical techniques to determine the correlations between factors: ordinal logistic regression with factors input, a generalized linear model with ordinal logistic response and covariates, and Spearman’s correlations. Based on 55 variables and 459 responses from 4 countries, the statistical calculations identify the 42 most significant pairs of relationships between determinants and success, from which the follow-up priorities involve economic differentiation, productivity in the factory setting, reducing uncertainty over the program, and minimizing disturbances in the vicinity of the site under post-COVID-19 controls. This empirical research generates three outcomes: (1) filling the gap of OSC review in the region, (2) offering topical solutions for the construction industry after COVID-19, and (3) helping four countries derive economic benefits from OSC.

The rapid development of new technologies has made the acquisition and processing of big data much easier and more accessible to various domains including construction management. This trend has resulted in numerous new technical or management issues in the field, as well as increased research needs. Thus, it is very necessary to invest and assess the past, present, and possible future developments of construction management-related studies. This paper provides a comprehensive bibliometric analysis of the articles published in this field over the previous two decades. The seven most popular research themes were identified and discussed with the data adopted in the related studies, including modern technology, waste management, performance management, risk management, project management, knowledge management, and organization management. Typical research data, research approaches, and future research directions were discussed. Emerging topics such as smart technology, sustainability, resilience, and human factors are suggested to be further explored in the domain. The review conducted in this study can provide some insights into what has been done and what can be achieved in future research in the construction management domain towards a data-rich era.

Quality problems are crucial in construction projects since poor quality might lead to delays, low productivity, and cost overruns. In case preventive actions are absent, a lack of quality results in a chain of problems. As a solution, this study deals with non-conformities proactively by adopting an AI-based predictive model approach. The main objective of this study is to provide an automated solution structured on the data recording system for the adverse impacts of construction quality failures. For this purpose, we collected 2527 non-conformance reports from 59 diverse construction projects to develop a predictive model regarding the cost impact of the quality problems. The first of three stages forming the backbone of the study determines crucial attributes linked to quality problems through a literature survey and the Delphi method. Secondly, the Analytical Hierarchy Process (AHP) and a Genetic Algorithm (GA) were used to determine the attribute weights. In the final stage, we developed models to predict the cost impacts of non-conformities, using Case-based Reasoning (CBR). We made a comparison between the developed models to select the most precise one. The results show that the performance of CBR-GA using an automated weighting model is slightly better than CBR-AHP based on a subjective weighting system, whereas the case is the opposite in standard deviation in forecasting the cost outcome of the quality failures. Using both automated and expert systems, the study forecasts the cost impact of failures and reveals the factors linked to poor record-keeping. Ultimately, we concluded that the outcome of non-conformities can be predicted and prevented using past events via the developed AI-based predictive model. Full article

A method for predicting the financial status of construction companies after a medium-to-long-term period can help stakeholders in large construction projects make decisions to select an appropriate company for the project. This study compares the performances of various prediction models. It proposes an appropriate model for predicting the financial distress of construction companies considering three, five, and seven years ahead of the prediction point. To establish the prediction model, a financial ratio was selected, which was adopted in existing studies on medium-to-long-term predictions in other industries, as an additional input variable. To compare the performances of the prediction models, single-machine learning and ensemble models’ performances were compared. The comprehensive performance comparison of these models was based on the average value of the prediction performance and the results of the Friedman test. The comparison result determined that the random subspace (RS) model exhibited the best performance in predicting the financial status of construction companies after a medium-to-long-term period. The proposed model can be effectively employed to help large-scale project stakeholders avoid damage caused by the financial distress of construction companies during the project implementation process.

Hospitals are complex buildings and their functionality is essential for patient healthcare. Definition, verification and implementation of accurate configuration information during construction projects are therefore essential. The purpose of this study was to develop a decision support system by establishing a value chain of configuration information with an end-to-end perspective. The approach of this study was explorative, investigating how building data can support construction projects in making hospital configuration decisions. A literature review provided a knowledge base about the configuration decision process flow, which determined the prerequisites for the proposed data and model management. Exchange and relationships of required building data were ensured by using Industry Foundation Classes (IFC) and a database model, respectively. The results show that using building model data for configuration decision support is feasible. A case study compared data exchanged in three construction projects of Magnetic Resonance Imaging rooms to those identified in the decision support system. Operational gaps regarding data exchange in the studied cases indicate what changes are required in current data collection and management. The contribution of this study is filling a research gap regarding end-to-end information management to support hospital configuration decisions in construction projects. Full article

Bar diameter is one of the basic factors affecting bond behavior, which is still of interest due to opposing opinions regarding its effect on bond behavior in the pull-out test. This paper presents an experimental and numerical bond analysis of ribbed reinforcing bar in concrete. The aim was to experimentally evaluate the effect of bar diameter on the bond behavior in the pull-out test and to perform numerical simulations of the conducted experiments in ABAQUS to verify their convergence to the obtained experimental results. The experiments used concrete of C35/45 grade and B500SP reinforcing steel bars of three diameters: 10, 12, and 16 mm. FEA simulations employed the Concrete Damaged Plasticity (CDP) material model and the Contact Cohesive Behavior (CCB) method to model the concrete–bar interface. The study shows that bar diameter significantly affects the bond, both on the bond stress–slip relationship and the type of bond failure, as well as on the bond strength. FEA simulations correctly reflected the bond behavior observed in the specimens. The analytical models presented estimates that were too conservative regarding the maximum bond stress relative to the experimental results. Full article

Reality Capture (RC) is a state-of-the-art technology for digital data gathering and visualization of the actual environment through virtual means. In recent years, RC has contributed significantly to the digitalization of the construction industry globally. However, there are no systematic critical analyses of the benefits and challenges of RC technologies in construction project management (CPM) to drive its adoption. This research provides a detailed overview of the potential benefits and constraints of RC to tackle CPM concerns successfully and efficiently. This study uses the PRISMA procedure to conduct a systematic literature review. Based on the inclusion and exclusion criteria set for the study, 96 articles were considered relevant for review. The articles were analyzed using content analysis techniques to synthesize identify emerging themes. A four-step procedure was used to classify the articles into pre-construction planning, designing and construction. The review show that (a) RC is useful during the planning and designing stage, as the success of a construction project depends on accurate data to reduce the risk of cost and time overruns; (b) the benefits of RC adoption are accurate data, reduced time spent on project monitoring, progress tracking, and quality assessment; (c) RC on a construction site aids in the resolution of the industry’s fragmented nature through collaboration; quick and prompt decision making through remote monitoring and control of projects. RC is used as a visualization tool and for digital documentation of as-built models, construction verification, and flaw discovery, thereby improving work processes to achieve project success; (d) the most challenging aspect of incorporating RC on a construction site is the high investment cost. In the digital revolution era, this study could aid in the knowledge and optimal use of Reality Capture in numerous areas of CPM. Full article

Public construction projects in Saudi Arabia are fraught with several challenges threatening open and fair competition, which consequently negatively influence the decision of contractors to participate in bidding. Nevertheless, the construction sector has witnessed rapid reforms since 2016, which have resulted in the issuing of new legislation and regulations as well as the creation of governing bodies. Hence, the concept of open and fair competition plays a significant role in the governance of these challenges in the upstream process of construction tendering. Therefore, this paper explores challenges that are hindering contractors’ participation in the tendering phase of public construction projects in light of these new legislations and authorities. Twelve challenging factors were identified from a structured literature review of previous relevant empirical studies available in online search engines since the 1980s. Those factors were measured through Delphi survey questionnaires, which provided respondents with the option of adding new challenging factors. Thus, twenty factors were identified. A descriptive method was used to determine and prioritize these challenging factors. The survey findings indicate that the most influential hindering factors are (1) awarding contracts based on the lowest bidder, (2) inadequate or incomplete specifications, (3) poor contract documents, and (4) poor cost-estimating practices. These findings are vital in exposing the lack of relationships between the construction industry, regulators, and stakeholders for robust partnerships, thereby helping to ensure the fair participation of contractors, which boosts open and fair competition concepts for public construction projects.

Building information modelling (BIM) has become increasingly popular in construction projects in recent years. Simultaneously, project management has received more attention from academics and practitioners worldwide. Many studies have suggested that perceiving collaboration and risk are critical for successful construction project management. This study investigates the current status and future trends in building information modeling (BIM) literature from the Web of Science database. This review systematically uses bibliometric and systematic literature review (SLR) methods through co-occurrence and co-citation analysis. First, 650 academic documents were retrieved from the Web of Science database. Then, co-occurrence and co-citation analyses were performed along with network visualization to examine research interconnections’ patterns. As a result, relevant keywords, productive authors, and important journals have been highlighted. The prominent research topics within the literature on building information modelling focus on the following topics: collaborative in BIM, integration of BIM, GIS and Internet of Things (IoT), barriers to the integration of BIM, sustainability and BIM, and risk assessment and uncertainty. Finally, the potential research directions are developing towards digital twin technology, integration of BIM and AI, and Augmented Reality (AR) and BIM. The presented findings of only 88 articles discuss the collaboration and risk issue in BIM for the construction industry and thus confirms the need for more studies on this topic to enhance the chances of successfully building information modelling projects. The review focuses only on the academic documents retrieved from the Web of Science database, thus restricting the coverage of the reviewed literature relating to building information modelling collaboration and risk.

Quality management in project administration can affect the costs and schedule of a project considerably. The immediate notable result of unacceptable quality in a construction project is the “dissatisfied client.” which can be interpreted as “customer loss”. Additionally, defective work is a synonym for problems such as dispute, because items of non-compliance with early agreements can be considered the main factor in triggering claims by the client. The integrated use of two modern technologies, namely Building Information Modeling (BIM) and Unmanned Aerial Vehicles (UAV) is proposed in this study to support project quality management (PQM). This study aims to develop the theoretical underpinnings to provide a quality management framework, formed by BIM-UAV, for housing projects in design-build (D&B) contracts. For this purpose, in the first step the causes of client dissatisfaction rooted in quality concerns were identified in two phases of design and construction. The next step was dedicated to the mapping of BIM-UAV capacities to address the identified causes of dissatisfaction of the client. In the final step, expert opinion was obtained to integrate the BIM-UAV capacities to the quality management framework. The findings and main contribution of this study to the body of knowledge is a guide for design-builders to implement BIM-UAV as an innovative quality management solution to improve their services and to gain the maximum level of client satisfaction, focusing on house building.

Within traditional design processes, decisions are often made based on individualistic values and late-stage assessments conducted on a predefined set of design alternatives potentially leading to suboptimal design decisions and conflicts. The issues are further amplified by the growing complexity of construction project management where an increasing number of stakeholders are involved. To address those issues, a shift is needed towards a collaborative early stage optimization-based design process. The current optimization-based design approaches are not appropriately integrating stakeholders and their preferences in the optimization process and thereby not reflecting the real-life design and construction process. In this study, we present a pioneering multi-stakeholder design methodology combining preference function modeling theory and a priori optimization enabling stakeholders to find the group-optimal design fairly representing their preferences. The application of the developed methodology is demonstrated on a real-life multi-storey building design case. The study provides a novel approach for managing design and construction projects for academic and industry stakeholders. It also sets the foundation for the further development of stakeholder-oriented optimization-based design. Full article

Cost overrun has remained a key risk of construction projects that can be prevented by utilizing new technologies. This paper aims to identify the gap in the literature, which can potentially be addressed by using digital tools and technologies, by reviewing the current and state of the art practices. The paper presents the results of a systematic and critical content reviews on cost overruns, to address the question of what factors are affecting the cost overrun. This paper also reviews how building information modeling (BIM) in conjunction with other tools, such as the common tools in the Asia and Asia Pacific regions, are used for cost estimation and monitoring. The paper presents the results of the content review, including their contributions and limitations, which are also used to set key directions for future investigations. A total of 176 papers was identified to develop the construction cost management (CCM) dataset. The method was a mix of systematic reviews, including co-authorship network analyses, co-occurrence analytical map development covering 5671 keywords, and content analysis including theme identification and a critical review of selected papers. The paper critically reviewed 63 selected papers from CCM, which are divided into four clusters based on their scopes: BIM adoption for cost estimation and quantity surveying; BIM implementation for a bill of quantity, risk paths, and cost overruns; cost control and management; and, finally, BIM, virtual design, and value management. A trend analysis using a set of 16 themes (e.g., 3D model, BIM, Decision, Energy, and Life Cycle) for all the papers over the past ten years was developed. The content of each cluster of papers was reviewed based on the frequency of the selected themes in each cluster. The content of each cluster of papers was also reviewed critically and gaps were identified, so a set of directions for future investigations are presented. Full article

Augmented Reality (AR) is a Construction 4.0 technology that is seen as a site-extension of Building Information Modelling (BIM). In addition to the practical aspect within the design and construction processes AR can be used to support teaching through visualizations and interaction. This article presents a new AR platform called “AR-supported Teaching”, applicable for both Architecture, Engineering and Construction (AEC) education and as a Construction 4.0 technology. The aim of this project is to increase the amount of AEC AR content available for education and to introduce students to the productive use of AR. During its development, special attention was paid to the needs of the AEC industry. Users can employ BIM models to create AR scenes before adding animations and annotations without requiring programming skills. The AR platform enables interaction with remote experts and is therefore also suitable for distance learning. In a pilot study, use cases were defined and students tested the usability of the applications. The results were positive and additional suggestions for improvement were made. The feedback and motivation of the students indicate that AR has a future in education, especially if enough AEC AR content and practical use cases are available. The latter also concerns the application of AR in AEC practice. Full article

Despite being a key provider of employment, construction work significantly contributes to poor mental health among young construction workers worldwide. Although there are studies on the psychosocial risk factors (PRFs) that make young construction workers susceptible to poor mental health, the literature is fragmented. This has obscured a deeper understanding of PRFs and the direction for future research, thus making it challenging to develop appropriate interventions. To address this challenge, we systematically reviewed the literature on young construction workers’ PRFs using meta-aggregation, guided by the PICo, PEO, and PRISMA frameworks. We sought to synthesize the domains of PRFs that affect young construction workers’ mental health, and to determine the relationships between the PRF domains, psychological distress, and poor mental health. A total of 235 studies were retrieved and 31 studies published between 1993 and 2020 met the inclusion criteria. We identified 30 PRFs and categorized them into ten domains, which were further classified into personal, socio-economic, and organizational/industrial factors. The findings of this review contribute to achieving an in-depth understanding of young construction workers’ PRF domains and their patterns of interaction. The findings are also useful to researchers and policymakers for identifying PRFs that are in critical need of attention. Full article

The construction industry is facing constant pressure to improve its poor safety record and low productivity rate. A significant amount of research has been undertaken to identify the best practices to enhance productivity and safety. Nevertheless, the mainstream research in the field of construction focuses on one of these issues rather than implementing a holistic approach to resolve them. Consequently, the interactions between productivity and safety cannot be fully understood. Recent studies have demonstrated that management strategies and practices for improving labour productivity can trigger a series of unintended consequences that affect safety performance in construction projects. However, the behavioural aspects of these unintended consequences have yet to be investigated. This research addresses the gap by measuring the impacts of seven management strategies for improving labour productivity on the safety behaviour of construction labourers. A total of 191 construction labourers participated in a survey designed based on the Management Strategy Assessment Index (MSAI). The results show that the implemented management strategies for improving labour productivity have a greater impact on shaping safety compliance (SC) behaviours than safety participation (SP) behaviours of labourers. This study took a further step by breaking down the management strategies to their constitutive practices and measuring their impacts on SC and SP, and labour productivity. This paper provides further insight into the complex relationship between the productivity and safety behaviour of construction labourers. The findings can help project managers to improve labour productivity without harming their safety unintentionally. Full article

In construction projects, owners’ and contractors’ decisions as to whether or not share their tacit knowledge transparently with each other determines the choice of project delivery and contracting methods and their collaborative behaviors in the projects. The dynamic of collaboration is a complex one and is often influenced by the other player’s intent to collaborate. This paper proposes a quantitative framework using game theory to analyze the collaborative dynamic interplay in construction projects. The framework demonstrates that when an owner’s and a contractor’s knowledge leveragability (L) is very high and synergy (S) is enhanced as a result of knowledge sharing in complex construction projects, the Nash equilibrium state lies beneath the Pareto frontier. This means that sharing tacit knowledge transparently about budgets by choosing the best value procurement with GMP or IPD contracts can promote collaboration and provide better payoffs to both stakeholders than not sharing the knowledge by choosing the Design–Bid–Build method using a low-bid procurement in conjunction with a fixed-price contract. This research contributes to the body of knowledge by proposing a theoretical framework that enables both owners and contractors to understand the economics of collaboration in the context of complex projects.

The earned value method (EVM) is an internationally known technique for project management that emphasizes the control of project cost performance and duration, thus allowing trends to be identified during execution and warning the project manager of variances that may affect the project so that they can take the necessary corrective measures. In this research, the finished projects of a construction company in the city of Cuenca, Ecuador, were assessed. EVM was applied to projects from a database developed with information from each one to rebuild past events, existing problems, and critical points and evaluate the performance over time. The results of this analysis are meant to determine the project’s success, calculating the cost variance at the end. EVM motivates project stakeholders to pay attention to costs and progress so that timely actions can be taken to optimize resources, resulting in the completion of a project within budget and on time. In conclusion, EVM plays an essential role in the integral management of the project in terms of scope, time, and cost. Moreover, there are now guidelines for applying this method as a control tool in future construction projects. Full article

This paper introduces and further applies an approach to support the decision makers in construction projects differentiating among a variety of deep excavation supporting systems (DESSs). These kinds of problems include dealing with uncertainty in data, multi-criteria affecting the decision, and multi-alternatives to select one from them. The proposed approach combines the analytic hierarchy process (AHP) with the fuzzy technique for order of preference by similarity to ideal solution (fuzzy TOPSIS) in a multicriteria decision-making (MCDM) model. The MCDM model emphasize the ability to combine expert knowledge, cost calculations, and laboratory test results for soil properties to achieve the scope. The model proved it had a superior ability to deal with the complexity and vague data that are related to construction projects. Furthermore, it was applied to a real case study for a governmental housing project in Egypt. Secant pile walls, sheet pile walls, and soldier piles and lagging are selected and studied as being the most common DESSs and as they satisfy the project requirements. The model utilized four criteria and fourteen comparing factors, including site characteristics, safety, cost, and environmental impacts. Based on the results of the model application on the investigated case study, a decision was reached that using secant piles as a supporting system in this project is mostly preferred. Furthermore, sheet pile wall, and soldier piles and lagging, come next in the ranking order. A sensitivity analysis is carried out to investigate how sensitive the results are to the criteria weights. In addition, the paper discusses in detail the reasons and factors which affect and control the decision-making process. Full article

Requests for information (RFIs) are frequently used by the architecture, engineering, construction, and operation (AECO) industry to resolve doubts and inaccuracies and to request complimentary information. However, they can be inefficient due to the lag between issuance and response, generating delays and cost overruns. The building information modeling (BIM) methodology allows for the integration of information by using virtual models and facilitating the control and management of RFIs; however, the full potential of BIM is not being exploited. Therefore, this work aims to analyze the RFIs of 17 high-rise building projects in conjunction with the application of BIM for their mitigation. To achieve this, categories of RFI categories were identified, the issuance and response process was analyzed, the building projects’ RFIs were classified, the most frequent problems were identified, the BIM uses that would allow for a reactive or preventive action were identified, and, finally, the potential benefits of BIM use for the reduction of RFIs were analyzed. The research showed that the correct use of BIM applications focusing on RFIs allows for an effective information review, generating preventive or reactive management of problems. Thus, it is possible to identify the recurrent causes of RFIs and those specialties issuing the most RFIs, with the objective of mitigating RFI submission in construction projects. Full article

Successful implementation of construction projects worldwide calls for a set of effective risk management plans in which uncertainties associated with risks and effective response strategies are addressed meticulously. Thus, this study aims to provide an optimization approach with which risk response strategies that maximize the utility function are selected. This selection is by opting for the most appropriate strategies with the highest impact on the project regarding the weight of each risk and budget constraints. Moreover, the risk assessment and response strategy of a construction project in Iran as a case study, based on the global standard of the project management body of knowledge (PMBOK) and related literature, is evaluated. To handle the complexity of the proposed model, different state of the art metaheuristic algorithms including the ant lion optimizer (ALO), dragonfly algorithm (DA), grasshopper optimization algorithm (GOA), Harris hawks optimization (HHO), moth-flame optimization algorithm (MFO), multi-verse optimizer (MVO), sine cosine algorithm (SCA), salp swarm algorithm (SSA), whale optimization algorithm (WOA), and grey wolf optimizer (GWO). These algorithms are validated by the exact solver from CPLEX software and compare with each other. One finding from this comparison is the high performance of MFO and HHO algorithms. Based on some sensitivity analyses, an extensive discussion is provided to suggest managerial insights for real-world construction projects. Full article

Resource management can determine the success or failure of construction projects and is indispensable in frame construction owing to the numerous resources allocated. Various research methodologies have been proposed for successful resource management, but they have not been conducted from a microscopic point of view such as activity. This paper quantitatively analyzes the impact of a concrete pouring team allocation on the project from a microscopic point of view, and proposes a framework for allocating the optimal team. Firstly, a time-dependent queueing model-based method is proposed for evaluating the influence of the pouring team for foundation concrete pouring. Data from large-scale apartment project cases in South Korea were used to verify this framework. Using time and cost metrics, the impact of the pouring team on the project was quantitatively analyzed. Finally, comparative analysis was performed to compare the concrete pouring team costs, including the average server cost and waiting cost before and after optimization. The proposed method reduced the total pouring team cost by 26.27% (KRW 35,547,600); it can help determine the optimal number of concrete pouring teams required for frame construction and improve the performance of construction projects from the process planning stage itself, by ensuring appropriate resource planning. However, since a single case was used, it is necessary to apply the proposed framework to actual construction after analyzing various cases in future studies. Full article

The construction industry in the United Arab Emirates (UAE) is faced with negative project performance, including low productivity, higher costs, delays in project completion, and defects during construction. One of the main reasons for these issues is the engagement of unskilled craft workers. Despite these labor issues, demand for construction projects in the UAE has been explosively increasing, in part due to Dubai winning the hosting of Expo 2020, which has given rise to an unprecedented demand for skilled construction craft workers. This study aimed to investigate the views and experiences of construction project managers regarding the reasons and challenges associated with the hiring of skilled craft workers in the construction labor market of the UAE. To fulfill the study purpose, the authors conducted structured open-ended interviews with UAE construction project managers. The results revealed several reasons for hiring craft workers despite a clear lack of qualifications and suggest some potential solutions. Full article

Risk appetite is a crucial component that plays a key role in the decision-making process of project risk management. Despite rising scholarly interest in project risk management, risk appetite has received little attention thus far. A well-defined risk appetite ensures that all decisions taken throughout the course of a project are consistent with an organization’s ultimate strategic aim. This research aims to identify the factors affecting the risk appetite of megaproject selection in the construction sector. The study adds to the knowledge of risk appetite in mega construction project selection and qualitatively examines the factors affecting risk appetite. Exploratory research design is used to identify these factors. The factors are identified using semi-structured interviews of 30 practitioners from the top and middle management working on mega construction projects. Thematic analysis was performed using NVIVO academic software. The most highlighted factors are financial attributes, board of directors’ agility, political factors, project location and demographics. The proposed conceptual framework identifies the factors affecting the risk appetite of mega construction project selection. These factors may be utilized as a starting point by construction project organizations to evaluate the risk appetite of a mega construction project. Risk appetite-based project selection will decrease chances of failures, delays, and cost overruns in mega-projects. These factors can be used by researchers as a rationale for developing predictive or descriptive models of project selection based on risk appetite. Full article

Fast-track construction projects are becoming increasingly prevalent in the construction industry, particularly where completion time is essential. A high adoption rate in some of the Gulf Cooperation Council (GCC) countries countries and the lack of a conceptual understanding of the challenges inherent in such may jeopardize the future sustainability of the construction sector. To make an informed decision about adopting a fast-track construction method, it is necessary to first identify the opportunities and challenges associated with it. Therefore, this study examines the critical challenges impeding the performance of Qatar’s fast-track construction projects. The research findings were analysed and triangulated using a real-life project as a case study and several data sources. The results of the research identified four critical categories of barriers: design and coordination-related, scope or change orders-related, material and equipment-related, and contractual-related barriers. In addition, strategies such as accurate information, constructability assessment, early involvement of operations and maintenance personnel, and the use of an effective change control system were identified for addressing the identified challenges. The findings are beneficial to professionals who are currently operating or planning to undertake construction projects in Qatar or other Gulf Cooperation Council (GCC) countries countries. This study recommends that project managers be more attentive to key barriers in order to improve the performance of fast-track projects and to meet clients’ objectives. Full article

As key technologies of the fourth industrial revolution, blockchain and digital twins have great potential to enhance collaboration, data sharing, efficiency, and sustainability in the construction industry. Blockchain can improve data integrity and enhance trust in the data value chain throughout the entire lifecycle of projects. This paper aims to develop a novel theoretical framework for the adoption of environmentally sustainable blockchain-based digital twins (BCDT) for Construction Industry (CI) 4.0. The paper identifies which key data from construction projects lifecycle should be anchored in BCDTs to benefit CI 4.0 and the environment. The paper also identifies key factors and non-functional requirements necessary for the adoption of BCDTs in a decentralized and sustainable CI 4.0. At first, a content analysis of the literature allowed the identification of which data from projects lifecycle would benefit from blockchain technology (BCT) adoption and what the key factors and non-functional requirements necessary for the adoption of BCDT in the CI4.0 are. Furthermore, the analysis of structured interviews and online survey permitted to firstly validate the hypotheses raised from the literature and to offer a novel framework for BCDT of CI 4.0 in the context of the circular economy (CE). The findings are that (1) the key project lifecycle data relevant for BCDTs relate to the BIM dimensions (3D, 4D, 5D, 6D, 7D, and 8D) and a new dimension called the contractual dimension (cD) is also proposed. (2) Ecosystems of BCDTs should embrace a novel form of collaboration that is decentralized and presented as Level 4 maturity for BCDTs. This new level of maturity leverages distributed blockchain networks to enhance collaboration, processes automation with smart contracts, and data sharing within a decentralized data value chain. Finally (3), the main non-functional requirements for BCDTs are security, privacy, interoperability, data ownership, data integrity, and the decentralization and scalability of data storage. With the proposed framework including the BCDT dimensions, the Maturity Level 4, and the key non-functional requirements, this paper provides the building blocks for industry practitioners to adopt BCDTs. This is promising for CI 4.0 to embrace a paradigm shift towards decentralized ecosystems of united BCDTs where trust, collaboration, data sharing, information security, efficiency, and sustainability are improved throughout the lifecycle of projects and within a decentralized CE (DCE).

This article describes the outcomes of the development of the project MATES to STEAM. The project is aimed at integrating Construction 4.0 content to a recently started new degree on Technologies on Civil Engineering. This integration is underpinned by the creation of STEAM-rich activities that can complement such degree. The philosophical design of these activities followed three requirements: (i) the activities should infuse Construction 4.0-related technologies, (ii) the activities should foster motivation among students with a STEAM vision by-design and (iii) the activities should be designed with a hardware-software independent perspective (open-source, accessible, affordable). Cornerstone and capstone projects as well as a set of workshops represent the demonstrators of these activities. All these demonstrators are knitted together in a single path in which an educational attempt to fill the identified Construction 4.0 gaps is proposed. The STEAM perspective provides completeness to the whole development. During the last two years, the project was developed and the design, the development and implementation of several demonstrators were completed. In the years to come, a systematic deployment and analysis of such demonstrators is expected when a full implementation of the new degree of Technologies in Civil Engineering will be addressed.

Collusive bidding has been an insidious issue in the construction industry. Bidders initiate collusive networks of various sizes to win market shares. The popularity of collusive bidding networks affects market fairness and erodes the interests of market players. Although considerable research efforts were made to diagnose collusive bidding networks, there remains a gap in knowledge regarding the relationships bid riggers use to engage in the networks. Therefore, this study used the social network method, where two hundred sixteen collusion cases were collected from China to test these relationships. The results show that collusive bidding networks were characterized by sparseness, a small scale, a high concentration, and strong randomness. Three types of collusive bidding networks were also detected: contractual, spontaneous, and shadow. Furthermore, these collusive bidding networks had discrepancies regarding participants’ identities, forms of collusive bids, and the determination of bid winners. It was found that the proposed social network model of deliberating bid riggers’ relationships lays a solid foundation for the detection of collusive bidding in the construction sector. Full article

In the province of Quebec, Canada, Small and Medium Enterprises (SMEs) in manufactured timber construction seeking to expand their market must necessarily go beyond the local trade. By exporting their products and manufactured building sections to another country, Quebec manufacturers must deal with significant regulations and certification constraints. The aim of this study is therefore to propose a method to qualify the impacts of these constraints on the export of manufactured buildings to New England in order to create a decision support tool. Since construction regulations vary depending on the location of the project, those relating to Massachusetts were analyzed, as this is currently the main destination for manufactured building sections. Considering the federal and local regulations in effect, a content analysis of the Quality Assurance Manual (QAM) set up by an industry partner and a third-party certifier enabling exports to Massachusetts was performed. In particular, the six-step method proposed by L’Écuyer was exploited for extracting and examining relevant information from regulatory texts. Through this analysis, the importance of quality control was confirmed as a keystone for certification. It also led to a better understanding of the relationships between quality control, the construction process and installation, the design and engineering choices, and the strategy to choose the project.

This research explores the failure of competitively tendered projects in the UK construction industry to procure the most suited contractor(s) to conduct the works. Such work may have equal relevance for other developed nations globally. This research seeks to teach clients and their representatives that “lowest price” does not mean “best value”, by presenting a case study of a successfully negotiated tender undertaken by a small-to-medium enterprise (SME) contractor; SME studies are relatively scant in academic literature. By applying the “lessons learnt” principle, this study seeks to improve future practice through the development of a novel alternative procurement option (i.e., negotiation). A mixed philosophical stance combining interpretivism and pragmatism was used—interpretivism to critically review literature in order to form the basis of inductive research to discuss negotiation as a viable procurement route, and pragmatism to analyse perceptions of tendering and procurement. The methods used follow a three-stage waterfall process including: (1) literature review and pilot study; (2) quantitative analysis of case study data; and (3) qualitative data collection via a focus group. Our research underscores the need to advise clients and their representatives of the importance of understanding the scope of works allowed within a tender submission before discounting it based solely on price. In addition, we highlight the failings of competitive tendering, which results in increased costs and project duration once the works commence on site. These findings provide new contemporary insight into procurement and tendering in the construction industry, with emphasis on SME contractors, existing relationships, and open-book negotiation. This research illustrates the adverse effects of early cost estimates produced without first securing a true understanding of project buildability and programming. Our work concludes with a novel insight into an alternative procurement option that involves early SME contractor involvement in an open-book environment, without the need for a third-party cost control.

The increasing complexity of building projects, with high quality standards, integrated technologies and strong management restrictions, demands the intervention of numerous and diverse specialists. This requires an intense leadership, organization and coordination effort. However, building regulations, such as the Spanish Law on Building Management (LOE) 38/1999, only formally consider developers, project designers, project and work supervisors, quality control entities, construction companies, owners and final users as building agents. However, these categories are insufficient to represent the interests of all the stakeholders. The purpose of this paper is to carry out an analysis of the agents that are currently part of the entire building process. If their relationship of influence and dependence, as well as their alignment with the overall objectives of the project are studied, potential convergences, divergences, agreements and disagreements can be established. To do this, the authors conducted a prospective analysis through the MACTOR (Matrix of Alliances and Conflicts: Tactics, Objectives and Recommendations) strategic planning simulation tool, for which the rules of the Delphi technique were applied and a consultation with technical experts, both professionals and academics, was held. The research provides insight to assess the power relationships between the building agents, as well as to measure the alignment of objectives with their interests. Results show that, in the context of integrated project management (IPM), the influence of technical agents is reduced by limiting their functions to those marked by their regulatory framework, allowing them to focus on their legal powers, and the room for manoeuvre of the professional agents, who are subject to systematized monitoring and control, is also reduced. The prospective analysis also highlights the importance of defining the scope from its early stages, as well as the need to reach multilateral agreements based on the other two main constraints: time and cost.

Free-form concrete panel production requires an increasing amount of manpower because the molds cannot be reused. There are many limitations when it comes to reproducing accurate forms due to the many manual processes. Therefore, the current study developed side mold control equipment that can automatically fabricate molds for free-form concrete panels. The equipment is capable of molding various shapes and sustainable operation. However, there may be errors as it automatically produces various shapes. Therefore, it is necessary to check the errors between manufactured shapes and designed shapes. The shape created using the side mold control equipment showed less than 0.1° error in side angle and ±3 mm error in side length. Therefore, the equipment manufactured a precise shape. Based on the findings of the study, the side mold control equipment will be used to produce accurate shape of free-form concrete panels automatically. Full article

The pre-project planning phase has a significant impact on the achievement of project objectives because during this stage, major decisions including involving contract strategies are made with a high degree of uncertainty. Studies show that the contract type can play a unique role in the achievement of project success. On the other hand, drilling projects can be considered as one of the most critical types of projects in the petroleum industry. In this research, a novel risk based best-worst method (risk-BWM) is proposed for solving the issue of selecting the best contract strategy. A three level methodology was designed; firstly, the risk breakdown structure (RBS) of drilling projects was created in four levels including one heading in level 0, eight main areas of risk in level 1, 34 sub-areas of risk in level 2, and finally, 217 risk items in level 3. Secondly and on the basis of BWM, the weights of risk factors were determined as the selection criteria and consequently the best and the worst criteria were specified. Finally, using pair-wise comparisons between six types of drilling prevalent in contracts, the most appropriate contract type was proposed. The contribution of this study is the development of a generic RBS for drilling projects and application of the risk factors for the first time for the selection of contract type using the BWM method, which has the potential of being adapted for other types of underground projects.

The issue of sustainability has long been the subject of interest in architecture engineering and the construction sector. All three aspects of sustainability—economic, environmental, and social—can be affected through appropriate construction waste management. Construction and demolition waste (CDW) is one of the largest worldwide waste streams, therefore, it is given great attention by all stakeholders (investors, contractors, authorities, etc.). Research studies show that one of the main barriers to insufficient CDW recovery is inadequate policies and legal frameworks to manage CDW. It is also one of European Union’s (EU) environmental priorities. The aim of the article was to confirm the economic potential of construction and demolition waste audit processing through a case study. A pre-demolition waste audit was processed for an unused shopping center building in the town Snina in Slovakia. Subsequently, a comparison of economic parameters (waste disposal costs and transport costs) of the recommended CDW management was performed. This comparison confirmed the economic benefits of environmentally friendly construction waste management methods according to the waste audit results, which would also increase the sustainability of construction projects. Additionally, the cost parameters of selected waste disposal methods could be another dimension of building information modeling. Full article

A contractor’s ability to prepare a competitive bid for a construction tender is crucial for its survival on the market. The bid price estimation strategy should promote the probability of winning a sufficient amount of tenders but, at the same time, ensure the economic stability and development of the company. This paper aims to address this issue in the area of Czech public construction procurement. The opinions, experiences and practices of contractors were collected through a questionnaire survey, and the data were evaluated with the support of statistical methods. This revealed that Czech contractors mostly base their multicriteria bidding strategy on cost-oriented pricing while considering various aspects such as the risks and attractiveness of the tender. The Czech construction market is generally perceived as oriented toward low costs, and with a relatively common occurrence of abnormally low bids. The findings presented in this paper may help contractors improve their current bidding strategies in public construction procurement. Full article

Studies show that procurement management and its processes strongly affect project success in the construction industry, because the project-oriented organizations in the construction industry prefer to buy goods and services from outside the project team and benefit from outsourcing. Hence, these organizations are continually facing different levels of procurement processes, and the establishment of a robust outsourcing system is crucial for success of their projects and development of their businesses. On the other hand, the housing projects are considered a significant sector of the construction industry in terms of the number of projects and the impact on the national economy. Traditionally, the key sources in conventional housing projects are the general contractors, the consultants and the suppliers. In this study, essential elements of an organizational system have been investigated by expert opinions and through the Delphi method, and all effective aspects of the source selection problem have been identified and integrated. Based on the research findings, procurement of housing construction projects should be organized in three organizational levels: development of the long list, preparation of the short list and selection of the most appropriate source by focusing on four main elements of the source identification method, criteria definition, evaluation arrangement and assessment model.

The number of new homes built in China in 2014 doubled compared to 2004, while Korea has built more than 3000 units every year since 2004 and Japan has built more than 6000 new units. Apartments account for 60% of homes in Korea, so it is anticipated that apartment construction projects will not cease in Korea. The current company assumes that the sale rate (pre-sale rate) of apartments may be completely controlled by the pre-sale prices. The study calculated appropriate pre-sale prices to maximize the revenue of companies based on that assumption. For that purpose, the study identified the factors affecting the pre-sale prices and analyzed its correlation with the pre-sale prices based on the apartments located in Seoul, Korea. As a result of the analysis, it was found that the pre-sale prices of apartments are correlated with the number of apartment complexes, local rates, and local development level. The final result of the study suggested a way to calculate the sale prices using the factors that are thought to be correlated with the pre-sale prices. A simulation model was created using the method. When tested, it yielded an average deviation rate of 10.32%. The current study will contribute to preventing the economic losses that may be caused by apartment construction projects. Full article

Sustainable Project Management (SPM) is a novel theme in construction industries of developing countries and very little is known (so far) about the sustainability performance of construction projects in those settings. Accordingly, the quantitative measurement of SPM as a higher-order construct is not well established and lacks a holistic approach and homogenous taxonomy of indicators. This study explores the SPM practices of construction firms by validating SPM as a second-order construct in the Pakistani construction industry. Data were obtained from 146 construction firms, which were then analyzed using partial least square structure equation modeling. Results of the first and second level measurement model assessments showed that construction firms practice SPM, with varying degrees of attention paid to three sustainability aspects. Environmental dimension surfaced as the most important, in-terms of practice and social sustainability as least. The analysis of the second-order measurement model yielded significant results, thus, validating the higher-order structure of SPM. This study contributes to the field by presenting one of the first studies of its kind by focusing on the sustainability practices of construction firms by using a higher-order design of SPM construct within the context of developing countries.

The aim of the article is to analyze three variants of modernization and reconstruction of a road intersection, which in practice is the cause of numerous collisions and accidents. Detailed design solutions are presented for them. The aim of the analyses is to indicate an effective solution that, taking into account technical modifications of the road system elements, will ensure the functionality of the road system to the highest degree and significantly reduce the number of road incidents. To indicate the optimal solution, quantitative data (cost and duration of activities for three options) and qualitative data (determined based on the own experience and knowledge of road industry experts) is analyzed. The authors refer to many criteria of various natures (e.g., economic, technical, functional, environmental, social), which allow for comprehensive consideration of the current requirements of road users and changing circumstances, among others a steady increase in the number of vehicles and growing social expectations in terms of road parameters. Considering the presented analyses and arguments, the authors recommend option 1 as optimal. This is the most expensive solution among those analyzed and with the longest implementation time, however, taking into account the long-term prognosis of the direction and scope of changes to the existing standards and requirements for road infrastructure, it can be stated that option 1 meets them to the highest degree, and also has the greatest potential. The envisaged solution ensures high standards of the quality of road infrastructure use in terms of functionality, capacity, technical parameters, as well as the safety of traffic participants related to the smoothness of the journey, reduction of the number of collisions and accidents.

Society and the business world are paying more and more attention to the Circular Economy (CE) principles. The construction industry is no stranger to this issue, and the companies are transitioning towards sustainable production models. However, it is not easy to predict when and to what extent a company implements the CE. To measure this process, a scorecard, that includes the main Key Performance Indicators (KPIs) of the construction industry, related to the CE, was designed. Thus, the objective of this article is to design and test the CE-dashboard applicable to the construction industry. To do it, firstly, a literature review is performed. The next step is the selection of the KPIs collected in the literature, more suitable for reporting information about CE. Afterwards, a simulation based on the Monte Carlo technique performs. After multiple iterations, this method establishes the most probable KPI values as a result, which will be confronted with the limits used in the scorecard. With all this information, the dashboard emerges in Qlik software. Finally, a test of this dashboard takes place according to the information about KPIs from one of the leading Spanish companies (General Contractor (GC) building company). This step brings the validity of the created measurement instrument. Full article

The aim of each investor is to procure the construction work in an efficient and economical way. This goal can be achieved by managing costs from the beginning of the investment process. It is necessary to determine the estimated price of the construction work in all phases of the investment process and not to underestimate the importance of this activity. It is almost a rule that the contractor or investor does not allow sufficient time for the contractor to prepare the construction for good quality, which may lead to insufficient preparation. The consequences of poor construction preparation vary from poorly built construction to litigation over the lost profits of the contractor—and this is the topic we discuss in this paper. The issue of asserting lost profits on the contract by the contractor is the subject of legal disputes between the contractor and the customer of construction work. In such cases, the question becomes the design of a methodology suitable for its calculation. The article deals with the presentation of the existing methods of loss of profit calculation, two of which are applied to the example of litigation from construction practice, with the definition of their results and differences.

In urban areas, tunneling works inevitably interfere with the adjacent buildings. In the preliminary design stage, designers usually do not inspect buildings adjacent to the construction sites, because these activities are often too expensive. This paper presents the STATUS app, an Android application for mobile data collection. It was developed and tested by Geofunction Srls before the beginning of the tunneling works for the railway doubling in Cefalù (Italy). The system assists technicians during visual inspections and records the pre-existing architectural and/or structural damages in buildings adjacent to construction sites in real time. The output of the data collection is an official report printed and countersigned in situ by the technicians and the owners of the inspected property. The application was used for 1189 inspections inside 96 buildings. The aim of the paper is to show the benefits achieved through the use of STATUS app. It is also useful for several purposes: external risk assessment, damage prevention, damage reporting, preventing future legal disputes, and the free-rider problems. The application is released under closed-source license. Full article

The aim of this study is to build a mathematical model of the productivity of construction workers. It does so by selecting 17 factors that influence the productivity of construction workers and categorising them into five groups. For the mathematical description of the factors, fuzzy logic was used. A formula for calculating the work productivity of construction workers is proposed. The novelty of the approach proposed by the authors is rooted in the consideration of various factors that have the potential to influence the productivity of construction workers. To present the way the formula operates, a single assessment of ceiling formwork was undertaken. The verification of a model confirmed its capability of analyzing, evaluating, and predicting the productivity of construction workers with satisfying accuracy. Full article
