1. Introduction
In early 2020, an outbreak of COVID-19 occurred in Wuhan, China, which was highly transmissible and led to a surge in the number of infections in the city within a short period of time, placing unprecedented, concentrated pressure on medical institutions [
1]. For the purpose of relieving pressure on medical institutions and restricting the spread of the epidemic, the Wuhan Epidemic Prevention and Control Command decided to build the TGMH to treat critically ill patients based on the experience gained during the fight against SARS in 2003 [
2]. In view of the severe epidemic situation, there have been numerous obstacles to the construction of the TGMH project, including an unfavorable construction environment, a shortage of construction personnel, and difficulties in controlling pollution [
3]. In spite of these difficulties, the construction process of the TGMH project was completed in just 12 days in accordance with all epidemic prevention standards, contributing greatly to Wuhan’s victory in the “anti-epidemic battle” [
4]. Consequently, the construction experience of the TGMH project has also led scholars to pay attention to its organizational resilience capability to resist shocks and complete construction tasks in crisis situations [
5].
The concept of “organizational resilience” can be viewed as an extension of the concept of resilience in the field of organizational management [
6]. The term “resilience” was originally defined in the field of physics as the ability of an object to maintain its basic form and function, even in the face of external force, or to quickly recover from the impact of external force [
7]. Later, this concept was applied to the field of organizational management to describe an organization’s ability to react to and recover from negative shocks, which is of great significance for the sustainable development of organizations [
8]. In view of this, a number of scholars have investigated the influencing factors and effects of organizational resilience in an effort to contribute to the cultivation and development of organizational resilience in the current social environment [
9,
10]. In the majority of current studies, organizational resilience is considered to be an integrated function of the knowledge, skills, and abilities of individuals in an organization, including cognitive, affective, and behavioral dimensions [
11,
12]. As an important component of organizational resilience, individual adaptation to the environment can be strengthened by employees strengthening their own learning capabilities [
13]. As an example, specified human resource management practices, which are designed to encourage staff to recognize crises and respond appropriately and efficiently to those crises, are suggested as one method to improve organizational resilience [
14]. However, research on this dimension of organizational resilience primarily explores how intrinsic behaviors and practices affect organizational resilience from a narrow perspective, neglecting the involvement of other organizations and the connections between them [
15]. As a result of this limited perspective, it may be difficult to pinpoint those factors that have a significant effect on the formation of organizational resilience [
16]. In this regard, some scholars have also explored the impact of factors such as the degree of linkages among organizations and organizational collaboration patterns on organizational resilience [
6,
17,
18]. Almost all existing research has been focused on developing macro-frameworks and qualitative descriptions [
19]. Although some aspects of organizational resilience are mentioned, the relationship between organizations lacks quantitative and clearly defined descriptions, and the relationship between organizational resilience and organizational collaboration behaviors is poorly understood. Additionally, the majority of these studies are theoretical analyses that offer little support for specific practical applications [
20,
21]. In order to clarify the cultivation mechanism of organizational resilience and its development path, in-depth and systematic empirical tests should be conducted with actual engineering cases in order to extend research perspectives on the influencing factors and effects of organizational resilience in adversity situations.
It is expected that the experience gained in the construction process of the TGMH project will provide valuable guidance for other countries and regions in the fight against the COVID-19 pandemic. The organizational collaboration pattern involved in the construction of this project may serve as an inspiration for other similar emergency projects to enhance organizational resilience. The objectives of this study are summarized as follows: (1) identify the various participants and their relationships in the construction process of the TGMH project, and characterize how the organizations collaborate with each other during the construction process; (2) develop a multidimensional and comprehensive organizational resilience index system that would be compatible with the TGMH project on the basis of the existing research on organizational resilience; (3) analyze organizational resilience based on organizational collaboration patterns through the results of relevant complex network parameters and the multidimensional organizational resilience evaluation index system, and develop strategies for enhancing organizational resilience.
In order to achieve the above objectives, the rest of the paper is organized as follows. The
Section 2 documents the existing literature on topics related to organizational resilience and complex networks in order to spot research gaps. The
Section 3 introduces the paper’s framework and outlines which methods will be employed for analyzing organizational resilience. The
Section 5 focuses on creating an organizational collaboration network model for the TGMH project and analyzing relevant network parameters. Based on the organizational resilience indicator system,
Section 6 conducts an analysis of the factors influencing organizational resilience and presents a set of possible suggestions. In the
Section 7, the findings of this study are summarized, and the contributions are discussed.
2. Literature Review
Regarded as the core of construction project management, organizations in construction projects are supposed to undertake a specific project task, the ability of which to function efficiently will have a significant impact on the project objectives, such as safety, quality and schedule [
22]. Organization resilience is considered to be the ability to cope with and adapt to external changes throughout the project’s life cycle, playing a key role in ensuring the achievement of construction objectives in the event of emergency [
23]. Hence, it is urgent to achieve a better framework for analyzing and assessing organizational resilience for construction projects faced with emergency situations. An extensive literature review was conducted to the determine research gaps in the relevant papers.
2.1. Research Status of Organizational Resilience
Organizational resilience, which originates from the complex system theories, describes the ability of organizations to avoid failure and losses, as well as to respond effectively after these have occurred [
24]. It is a kind of multifaceted organizational capability that is embedded in external social relations and internal member relations, which are closely related to the types of relationships between organizations, relationship patterns, and the organization’s status [
25,
26]. Positive social relationships between organizations can contribute to the efficient exchange of resources and minimize negative losses due to miscommunication within the process so that the agreed benefits are realized [
27,
28]. Furthermore, informal relationships between organizations have been found to exist as well. For example, a positive experience of collaboration can result in high levels of trust, which in turn helps to facilitate the efficiency of resource allocation and risk-sharing [
29,
30].
Assessment of organizational resilience lays the foundation for further research on defining organizational goals and optimizing organizational resilience [
31]. Therefore, scholars have proposed a wide range of effective methods to measure organizational resilience objectively and accurately, which can be divided into two main types, namely qualitative and quantitative [
32]. Existing qualitative methods of measuring organizational resilience mainly developed certain indicators which can represent different dimensions of organizational resilience and conducted the analysis with different methods [
23]. For instance, combined with a measurement model of “Relative global resilience” (ROR) a series of semi-structured interviews were conducted to explore the level of organizational resilience with fifteen organizational resilience indicators [
33]. Based on the resilience analysis grid, the level of organizational resilience was measured from three dimensions, including cognitive, behavioral and contextual resilience [
34]. Though these models and indicators can roughly provide a comprehensive and systematic estimation of organizational resilience, they are weak for explaining the underlying influencing factors of organizational resilience. As a consequence, quantitative methods are needed, which has led to a rich body of literature. There have been many attempts to create functional models to assess the level of organizational resilience in diverse systems. A belief function model was built to measure the changes of the preset organizational resilience indicators after supply chain risks occurred to measure organizational resilience level [
35]. Based on that, another functional model considering both demand satisfaction and cost has been used to investigate the changes of relevant indicators under shock to measure organizational resilience [
36]. In addition, graph-based research usually abstracts the units and connections in the network into nodes and edges and proposes a formula for measuring network resilience [
37].
It can be seen that purely mathematical methods can provide quantitative analysis results of organizational resilience, but the limited conditions and computational procedures applied will make it a challenging process to perform in a variety of situations [
38]. More importantly, these methods are also weak in analyzing how organizations collaborate in complex systems, which have been shown to be an important feature of complex systems [
39]. The case of the TGMH project selected for this paper is a complex adaptive system where additional attributes can be generated through the interconnections between elements. Clearly, inter-organizational collaboration in the TGMH project may be an important aspect of organizational resilience. Therefore, the complex network approach is more applicable than these approaches to model the organizational network of the TGMH project. This method tends to address the linkages between all participating units and is superior for exploring the level of organizational resilience of projects at the organizational collaboration level, which will make an important theoretical contribution to the study of organizational resilience. Moreover, by combining network parameters and organizational resilience indicators, the scope of research on complex networks in the field of engineering projects is expanded.
2.2. Application of Complex Network
A complex network is a theoretical approach that combines integrity, randomness, complexity, and dynamics, which can reveal the overall functional and evolutionary characteristics of complex systems through connection behavior between the topology and nodes of the network [
40]. Any complex system containing a large number of constituent units (or subsystems) can be considered a complex network when the constituent units are abstracted into nodes and the collaboration behaviors between the units are abstracted into edges [
41]. In time and space, the analysis of network parameters, connection mechanisms, and orientations may reveal features of complex systems that are not instantly evident [
42].
Related research has been extensively applied in the modeling and resilience evaluation of topological networks in ecological systems, safety systems, transportation networks, and social networks [
43,
44,
45,
46], mainly to establish a relationship between the network topology and resilience in the networks [
47,
48]. Network features, such as the average path length, clustering coefficient, and size of the largest connected component, were analyzed with the resilience characteristics in the supply chain network [
49,
50]. From the view of the social capital of stakeholders, a network made up of community stakeholders and the relationships among them was constructed to analyze community resilience, which can be evaluated from multiple dimensions, such as redundancy, robustness, and resourcefulness [
51]. In the meantime, with the deepening of complex network applications, dynamic analysis of resilience can be conducted by adopting strategies, such as node-based random failure and targeted attacks [
52,
53].
Thus, abundant resilience evaluation models and indicators make it possible for complex network theory to be used in the organizational resilience research of the construction industry [
12,
54]. However, only a few studies have analyzed these features in the context of construction projects. Existing network-based research on the resilience of construction projects is often based on a certain type of unit in the project which is too limited to express the complexity of organizational collaboration behaviors. The diversity of organizations and corresponding relations in the construction project to the project has been neglected, which would result in an inadequate analysis of organizational resilience [
55]. Meanwhile, existing theoretical research is dominant while discussions combined with the actual engineering cases only occupy a small part. Therefore, the practical significance of the hypothetical results remains to be verified.
3. Methodology
The logical framework of the paper is illustrated in
Figure 1, including three core parts.
In the first part, existing literature with an emphasis on organizational resilience has been compiled to acquire preliminary indicators of organizational resilience. Then, a similar literature search process was conducted with the focus of the complex network parameters corresponding to the organizational resilience indicators. The focus group method is employed to screen the repetitive and fuzzy indicators. Consequently, rapidity, diversity, clustering, and assortativeness, along with their corresponding network metrics, are identified as the final organization resilience indicators in this step. The multi-dimensional evaluation system of organizational resilience has been determined in the part.
In the second part, the paper adopts the brainstorming method to resolve the principles of recording organizations and their collaboration behaviors firstly. News reports relevant to the construction of the TGMH project are collected through content analysis to obtain the coded organization list and quantified organization collaboration information in the following. Software NET-miner6.0 has then been utilized to establish the organizational collaboration network of the TGMH project, which not only realizes the visualization of organizational collaboration but also provides calculation results of related network parameters. Subsequently, the paper focuses on the analysis of global characteristic parameters and local characteristic parameters of the TGMH project organization collaboration model.
In the last step, the results of parameter analysis are analyzed with the multidimensional evaluation system of organizational resilience established to reveal the organizational resilience mechanism of the TGMH project. Then, the advantages and disadvantages of the network model and the multi-dimensional evaluation system of organizational resilience constructed in this paper are also discussed. Accordingly, measures on how to improve organizational resilience in similar construction projects under emergency situations have been proposed.
4. Developing the Organizational Resilience Indicator System
4.1. Steps of Collecting Indicators
In this paper, the process of determining the organizational resilience indicator system using the literature method is accomplished in three major steps.
In the first phase, we identified the literature search databases, including Web of Science, Springer, Elsevier SD, and Wiley, then determined the literature search criteria, where the search terms (organization and resilience) were set in the “Topic” box covering title, abstract, and keywords, and the publication time range was set from 2011 through 2021. As part of the initial screening process, a large number of irrelevant articles were excluded through the title and abstract screening for reduced review workload. A snowball search was then conducted to identify all the articles to be analyzed by collecting references from the articles first screened. Following the ranking of all organizational resilience indicators according to their frequency of occurrence, six indicators with a frequency of at least five times were identified, including rapidity, diversity, assortativeness, clustering, redundancy, and flexibility.
The second phase began with selecting the same literature search databases as the first phase; then, we selected “network analysis” and six indicators under the “subject” box and conducted six independent searches. All other search conditions and preliminary screening were the same as in the first step so that all articles using network analysis to measure organizational resilience indicators were identified. By analyzing the frequency of all organizational resilience indicators, complex network metrics with at least five occurrences were identified.
In the third phase, eight experts with extensive experience in construction projects and scholars with conducted extensive research in organizational resilience were invited to take part in a discussion in order to provide a more scientific and reliable indicator system. They are from Wuhan Urban Development Bureau, China Construction Bureau, China Construction Bureau, Wuhan Real Estate Group, Central South Design Institute, Wuhan University of Technology, Huazhong University of Science and Technology, and Wuhan University. Having identified the time and place of the discussion with the experts, the experts engaged in a free discussion on which indicators should be invoked as indicators of organizational resilience, which was recorded by the moderator. The significance of each indicator collected earlier has been discussed, as well as its interpretation in terms of organizational resilience. It was determined that some indicators had the same meaning for different reasons for assessing organizational resilience, and therefore several of these were recommended to be eliminated or combined. More than half of the experts identified redundancy and diversity, as well as flexibility and rapidity, as indicators that have similar meanings. After a vote, rapidity, diversity, clustering, and assortativeness were identified as critical indicators of organizational resilience.
Table 1 will present statistics derived from the systematic literature review of organizational resilience indicators as well as pertinent complex network metrics Then, the interpretation of these indicators for organizational resilience indicators and the meaning of the corresponding complex network metrics will be discussed.
4.2. Interpretations of Organizational Resilience Indicator System
- (1)
Network metrics for characterizing rapidity
The rapidity of organizational systems, comprising the entire network and its nodes, is an essential measure of factor transport efficiency. Due to the increased speed of transport, organizations will be able to recover from negative shocks more rapidly. The rapidity of a network can be determined by its average path length, and the rapidity of its nodes by their betweenness and closeness centrality. A path in a complex network is composed of edges between nodes and neighbors, and the number of edges from node a to node b is referred to as the “path length” [
69]. The average path length of the network is defined as the average of the paths linking any two nodes in the network. A smaller value for the average path length would indicate a more compact and concentrated network, in which the nodes are more likely to incorporate and become rapidly connected. The concept of node betweenness centrality was introduced to describe the sum of the number of shortest paths going through a node for all pairs of nodes in a network [
70]. “Node closeness centrality” is a concept developed later based on the “closeness” of each node, namely the distance between that node and the other nodes [
71]. The degree of node betweenness centrality describes why a node occupies its current position in a network from the view of nodes receiving, delivering, processing, and even coordinating resource and information flows. The node closeness centrality value quantifies the node centrality in terms of its closeness to other nodes. The greater the value of this parameter, the simpler it is for the node to build direct or indirect linkages with other nodes.

Network metrics for characterizing diversity
Diversity refers to the ability of an organization’s interactive system to continue functioning after a partial failure caused by a shock or internal conflict. As diversity in the system increases, there are more pathways for elemental flow and sharing of external shock within the organizational system and thus a more resilient entity [
40,
72,
73,
74]. A measure of this characteristic is the average number of independent paths, which is defined as the sum of the number of independent paths between all node pairs in the network [
69]. This metric determines how sensitive nodes are to the performance of shared links. When external shocks induce partial destruction of linked edges, yet there are still alternative paths providing connections between nodes, the aggregate network is more likely to remain connected as the value of this parameter rises. Consequently, the average number of independent paths within the network is used in this paper as a measure of the diversity of the second of the organizational resilience indicators, with the following analytical steps. Firstly, a node and its connected edges are removed from the network. In a second step, the difference between the average number of independent paths in the original and current networks is calculated. In a third step, the size of the difference among all nodes is compared to determine the contribution of each node to diversity.
- (3)
Network metrics for characterizing clustering
Clustering refers to the degree of density of the organizational interaction system, including both global and local clustering. A network with a higher overall clustering of nodes tends to have stronger ties among organizations, more trust between them, and greater organizational resilience. However, the phenomenon of excessive node clustering may easily lead to localized grouping, structural closure, network stiffness, and therefore diminish organizational resilience. The node clustering coefficient measures the local grouping of nodes in a network, while the global network clustering coefficient measures the overall grouping of a complex network [
75]. The clustering coefficient of a node is defined as the ratio of the actual number of edges between key neighbor nodes to the total number of possible edges, whereas the global clustering coefficient of a network is the average of the clustering coefficients of all nodes. The node clustering coefficient quantifies the degree of clustering among all nearby nodes of a node and represents the probability that any two neighboring nodes of a node also share contiguous edges. Obtaining a high value for this metric indicates that the node has a greater capacity for uniting or leading its neighbors. However, it differs from node closeness centrality in that it assesses a node’s closeness to its neighbors, as opposed to all other nodes [
76]. According to the global clustering coefficient, the vast majority of complex networks in the real world are not completely random but involve some “clustering of objects and clustering of people”.
- (4)
Network metrics for characterizing assortativeness
Assortativeness is an indicator for measuring whether similar organizations tend to associate with one another. The lower the assortativeness, the less likely organizations are to form ties across hierarchy, cultures, and economic background differences. Decreasing the assortativeness of organizations enhances the overall synergy of the organizational interaction system, and thereby increases the organization’s resilience [
73,
74,
77]. Due to the fact that degrees are correlated in the degree distribution of a real-world complex network rather than being uncorrelated (unless it is a network that is completely random), degree correlation is an important statistical feature of a network, which can be also used to describe the tendency of nodes in a network to prefer to connect with nodes that have similar characteristics to themselves. Network visualization software NET-miner6.0 refers to the metric describing this property as “assortativeness metric”. In a degree correlated network, when the nodes with large degrees tend to connect the nodes with larger degrees in general, it is obvious that the degree distribution is positively correlated. As described above, the network is assortative and its assortativeness metric is more than zero. On the other hand, a degree negatively correlated network will have disassortativeness characteristics and an assortativeness value of zero.
5. Establishing the Organization Collaboration Network of the TGMH Project
5.1. Content Analysis for Identifying Organizations and Their Collaborations
From the news coverage generated during the TGMH project, the content analysis method was chosen to obtain the organization and collaboration information of the TGMH project. On the one hand, the project has received plenty of media coverage during its construction, resulting in a large number of articles about its construction due to the specific nature. On the other hand, the immediacy of news coverage in this primal exploratory research can provide valuable implications for objective and accurate insights into this research given the lack of previous efforts in exploring this project. In general, news coverage has been widely regarded as providing constructive, realistic, and credible information about current events [
78]. Analysis of them can provide a comprehensive understanding of the overall situation and even lead to the discovery of the hidden story. Content analysis of news reports is one of the most systematic and objective methods for identifying relationships between covered objects or events in the surrounding environment, by which 100 papers were consulted to explore the influencing factors affecting safety in construction projects [
79] and the media coverage of climate change at the national and regional levels in Russia during 2017–2018 was analyzed to identify the level of public demand for policy action [
80]. Additional methods of research, such as questionnaires and interviews, have certain limitations in the context of this case. In terms of the questionnaire method, the diversity and large number of complex construction organizations that participated in the construction of TGMH project contributed to the difficulty of designing the questionnaire, which resulted in less credible responses from respondents. Such factors can have a negative effect on the validity of the research findings and conclusions. The interview methodology has several limitations, including the difficulty of interviewing a sufficient number of construction organizations and the potential omission of some less significant organizations, resulting in an inadequate and unrepresentative sample size [
81]. As an additional concern, relying on personal recollections or assumptions for measuring is likely to cause the detachment from reality and bias that can occur through the interview method [
82]. Accordingly, the content analysis method was implemented to obtain data related to the organization and its collaboration in order to obtain a realistic and systematic description of the organization’s activities. Three key steps are involved in the implementation process.
- (1)
Selection of samples for analysis
The sample selected for analysis in this paper is derived from all the information on the construction of the project found on the official websites of all the key participants of the TGMH project, such as the third bureau of CSCEC, as well as authoritative media, such as People’s Daily, with a total of more than 900 relevant news texts. The names and links of each website are listed in
Appendix A. The time frame for the release of this information began on 25 January 2020 (when construction began on the TGMH project) and ends on 15 October 2021.
- (2)
Coding of organizations and their collaboration behaviors
As part of the text analysis process, text code books must be comprehensive but not complex, extensive but not general, and specific, but not excessively detailed [
83]. Accordingly, the brainstorming method is utilized in order to address the topic of organizational classification criteria and principles of identifying organizational collaboration behaviors. Three steps are involved in brainstorming: first, the moderator proposes a central topic for discussion; then, each expert engages in a free discussion on the topic and documents the discussion; and finally, the experts’ discussions are summarized, and the required results are determined. A total of seven experts from various work sectors with direct relevance to the case participated in the process, including government agencies, such as the urban-rural development bureau of Wuhan; construction units, such as the third bureau of CSCEC (the main construction unit of the TGMH project); and design units, such as the Central China municipal engineering design research Institute (the main design unit of the TGMH project). Three steps were applied in the brainstorming process. Firstly, the moderator proposed the principal topic for discussion, followed by each expert starting a free discussion on the topic and documenting the discussion process, and finally, the results of the experts’ discussions were summarized. This discussion identified the functional characteristics of relevant organizations as the classification criteria, where each building organization category consists of the related building organizations. In addition, the frequency of collaboration between the organizations was recorded for statistical purposes. Following the development of the code book, the coders manually extracted, analyzed, and recorded the building organizations and their collaboration, and eventually achieved the organizational results shown in the table below, while the organization collaboration data are attached in the
Appendix B.
This is an illustrative example of the content analysis approach in this study, an article published on 24 February 2020, in the Xinhua News Agency client titled “The “Chinese Power” Behind the construction of the TGMH project”. Firstly, the construction of the TGMH project was completed jointly by the third bureau of CSCEC and the eighth bureau of CSCEC, and the electrical circuits and some medical containers were installed by the eighth bureau of CSCEC as part of its construction. The statement above can highlight the two main construction units involved in the construction of the TGMH project and can also indicate the close relationship of collaboration between these two construction units.
- (3)
Reliability test
To verify the reliability of the data collected and recorded, this paper randomly selected 15% of the study sample to verify the quality of the data. Each coder analyzed and recorded building organization information from these selected samples, and then compared their results with the original researchers’ codes. Test results showed that the inter-coder agreement was 89.2%, which was in compliance with the reliability test criteria.
5.2. The Visualization of Organization Collaboration Network Model
On the basis of the information collected through the content analysis method in the previous section, this paper imports data concerning organization nodes (listed in
Figure 2) and their collaborations with each other into the software NET-miner6.0 to create the network of the TGMH project, as shown in
Figure 3 below. The network consists of 44 organization nodes which refer to the different organizational units, including construction units, design units, and government agencies involved in this construction project.
5.3. Parameter Analysis and Results
In order to gain a deeper understanding of the collaboration behaviors among various organizations, this section analyzes the metrics of the organizational network of the TGMH project at two levels—the overall network and individual nodes. From a macro-scale to a micro-scale, the linkage analysis offers a new insight into the collaboration behaviors between the various building organizations in the TGMH project, which, in turn, provides new insight into organizational resilience of the TGMH project. The complex network parameters involved and their relevance with the organizational resilience indicators are shown in
Figure 4.
5.3.1. Results of the Overall Network Metrics Analysis
The average path length of the network was 1.851, which meant that the average distance between any node pair with a direct or indirect pointing relationship did not exceed 2, indicating that there was no more than one transit “bridge” node on average between two nodes with direct or indirect connections. The shorter average path length reflected the higher network transmission speed, lower node interoperability cost, and wider node reachability, which facilitated the establishment of complementary connections and collaboration behaviors among the participating units mainly for personnel mobility, technology diffusion, and information transfer.
An average clustering coefficient of 0.609 suggested that the overall clustering effect of the network is more obvious, with fewer edge nodes in the network and a tendency for most nodes to coalesce into small trust and cooperation groups. Additionally, a larger average clustering coefficient also meant that information and resources are spread more effectively, boosting network capacity and resilience.
The network’s assortativeness coefficient was −0.293, which demonstrated the degree of collaboration between nodes of similar degree in the network. Given to the network’s negative congruency measure, nodes preferred to collaborate with nodes with larger degree differences, indicating network heterogeneity. The TGMH project’s core construction organization nodes engaged with companies of comparable size and scope as well as marginalized groups that varied from themselves. These marginalized groups might benefit from direct connection with the main group.
5.3.2. Results of Node-Level Metric Analysis
- (1)
Node centrality analysis
Closeness centrality values of all the nodes in this network were aggregated and ranked from largest to smallest, and the top ten nodes in terms of metric values are shown in the left half of
Table 2. Node C1 represented the organization with the largest value of closeness centrality, which indicated that, when compared with the other organizations in this project, the third bureau of CSCEC maintained the strongest connection to all the others. In the diagram of the network topology, it was shown as being closer to other nodes than any other node, while in the actual collaboration system, it appeared to reflect its effort to establish direct links with other organizations. Considering that node closeness centrality combined all the path lengths associated with a node into a single metric measure and path lengths were negatively correlated with transmission speed, node C1 was generally expected to take the central position in resources input and output. The closeness centrality values of nodes G2, G4, G1, and A were only second to node C1, implying that the construction headquarters of the TGMH project urban-rural development bureau of Wuhan, WHPPC, and HCLA also significantly contributed to the integrated planning and allocation of resources. The network had a structural feature called “one core with many sub cores,”, which made it easier for key nodes to connect, reduced the pressure and workload of the most important organizations in response to external contingencies, and thus reduced the risk of the system collapsing. It implied the significance of good internal information transmission of the organizational collaboration system to maintain its own resilience. This structure lessened the risk of systemic collapse, reflecting the value of effective internal transmission of the organizational collaboration system to sustain its own resilience.
Results of the betweenness centrality values of each node are summarized and listed in
Table 2 in descending order. As opposed to closeness centrality, which measured the speed of communication between two nodes, betweenness centrality measures the number of resources or information transmitted through each node. Results of metric calculations indicated that the third bureau of CSCEC only contacted efficiently with other organizations but also acted as a mediator, allowing various organizations to establish indirect links. A similar pattern was observed in the ranking results of closeness centrality values; betweenness centrality values of nodes G1, G4, and G2 also ranked in the top five, thus confirming that the two government departments and the hospital’s project leadership played a crucial role in resource control and integration. Moreover, the high betweenness centrality rating of node T reflected the efficiency of logistics and transportation businesses in timely distribution and circulation of goods.

Node clustering analysis
Table 2 presented the node clustering coefficients in order from the largest to the smallest values, with only the top ten nodes listed due to space limitations. The clustering coefficients of nodes (C7, C5, C8, and C6), ranging between 0.8182 and 0.8451, were significantly higher than those of the other nodes, suggesting that all the organizations with contacts to the four organizations were in more frequent contact. The network analysis revealed that these nodes are all construction units. The clustering coefficients of nodes P2, P3, P4, P6, P7, and P1 were relatively close, ranging between 0.762821 and 0.790441, indicating that multiple suppliers, such as lighting, electricians, and water supply and drainage engineers, were cooperating to complete the construction task quickly and efficiently. Based on the perspective of organizational resilience, the network tended to flatten network connections and the connection paths were heterogeneous and diversified, which enhanced the efficiency of information exchange and technical exchange and thus facilitated the completion of the TGMH project in such a short period.
- (3)
Node diversity analysis
The ten nodes that resulted in the greatest values of network diversity after failure are listed from largest to smallest in
Table 2. In general, construction organizations that had a significant impact on the project’s organizational resilience can be categorized into three groups, namely government departments, large construction units, and relevant associations. Among them, Wuhan Headquarters for Pandemic Prevention and Control (WHPCC) was the node that had the most impact on the diversity of the network. When it failed, the average number of independent paths in the network decreased from 46.4498 to 26.861. The dramatic loss of collaboration paths in the network was highly likely to contribute to network inefficiency and even functional paralysis. Beyond completing the primary construction work of the TGMH project, HFIC helped coordinate and organize activities for upstream and downstream enterprises in order to expedite materials transfers. Associations, such as the provincial federation of commerce and industry, utilized their functional advantages in the project construction process, soliciting and directing various construction organizations to participate in the project construction process, thereby resulting in a great influence on network diversity.
6. Discussion and Suggestions
The parametric analysis of the organization collaboration network presents an overall and precise description of the collaboration behaviors throughout the construction period, thereby providing a reliable research basis for the analysis and assessment of organizational resilience in the TGMH project. To investigate the influencing factors of organizational resilience, this section will discuss the relationship between the collaboration pattern and organization resilience indicators based on network analysis, the advantages of multidimensional organizational resilience indicator system and the organization collaboration model, as well as suggestions on enhancing organizational resilience for other construction projects faced with large public emergencies.
6.1. Organizational Resilience Analysis of the TGMH Project
Based on an analysis of the average path length and node centrality of the TGMH project, it can be observed that some key nodes play a substantial role in enhancing network rapidity properties. A previous study based on data from the National Quality Award-winning projects in the last decade concluded that when the average path of the collaborative network of the construction units in the project was shorter than about four organizational nodes, the project showed good connectivity characteristics, and the transmission path of the TGMH project required only two nodes, which meant that various construction resources could be integrated on a large scale through the transmission of fewer organizations [
54]. In this regard, the construction headquarters of the TGMH project, associated government departments, such as the urban-rural development bureau of Wuhan, and construction units, such as the third bureau of CSCEC, played a significant role as intermediary units for all other participating units in the project to optimize resource distribution and transmission. Due to the fact that the majority of the participating units were temporarily deployed across the country during the initial development process, they lacked experience in cooperating with one another, and poor communication and coordination tended to result. By establishing a detailed construction program and schedule, the third bureau of CSCEC and other units were able to more efficiently integrate the project resources and enhance the efficiency of collaboration between various departments within a relatively short time period [
64]. Researchers have further shown that an operational model in which key nodes coordinate resource allocation can increase project rapidity in cases of communication barriers among project participants [
84,
85]. However, this management model is not applicable to all types of construction projects. Critical nodes have played an important role in enhancing the rapidity of projects, but the importance of these nodes has been proven to diminish as project complexity increases [
57]. As projects become more complex, it can become increasingly difficult for key nodes to allocate resources to multiple project organizations, which can result in wasted resources. In addition, complex organizational collaboration behaviors may result in a reduced speed of resource transfer and the efficiency of resource allocation in a project.
Second, combined with the results from the analysis of network diversity, it can be found that the nodes with a high impact on rapidity often overlap with those that have a high impact on diversity, and only very few nodes demonstrate a clear preference for either rapidity or diversity. The nodes with a high impact on diversity, for example, government departments and construction units, are not only highly centralized, but they also have a significant influence on the diversity of networks after they fail. A similar phenomenon has been observed in the transportation network, which showed that the length of intercity passenger paths and the number of branching paths are both frequently adversely affected during a disaster or crisis, resulting in a severe decline in network capacity [
46]. Thus, this type of node is crucial to organizational resilience, both as a bridge for communication between other nodes and as a necessary node for maintaining diverse connections among nodes [
26]. Thus, increasing the capacity of key nodes in the network to efficiently carry out the “bridge” functions is an important component of increasing organizational resilience of the TGMH project. However, due to the extreme concentration of resources and the tremendous information load, the performance of these nodes in a construction project can largely contribute to overall project performance. The failure of such units has a superimposed influence on the organizational resilience of the project [
23]. Consequently, in a sense, this category of nodes may constitute the most significant source of project risk.
Additionally, the results of the overall clustering coefficients and the node clustering coefficients for the network of the TGMH project show that the project network exhibits a distinct small world characteristic, namely a shorter average path length and a larger clustering coefficient. As a result, the higher clustering coefficients primarily represent the difference between the TGMH project network and a random network, which implies that the probability of neighboring nodes being connected is considerably higher than that of non-neighboring nodes in the TGMH project network [
50]. This type of network may be attributed to the presence of “shortcuts” between node connection, in other words, long edges created during random reconnection [
86]. As noted in previous analyses, one of the distinctive features of the TGMH project is that nodes exhibiting similar business attributes and functions tend to connect with each other and form cliques [
87]. This feature explains why “shortcut” connections exist among the participants of the TGMH project. A similar phenomenon was observed in collaborative networks of project organizations utilizing BIM technology in Hong Kong in the form of the “similarity effect” [
88]. The reason for this phenomenon may be explained by the fact that project owners typically establish partnerships with consultants and prime contractors who share a similar organizational ownership styles and have experience with BIM. In contrast to the above statement, the cause for “shortcuts” can be explained by the reason that those project organizations seek to partner with organizations with prior experience in collaboration to reduce the level of collaboration uncertainty [
27]. As a consequence, clustering is a long-term trend that results from participants seeking the most cost-effective and convenient geographical location for collaboration in the project [
49]. As a result, projects with “clustering characteristics” facilitate the efficient integration of resources, increasing organizational resilience of the project. Additionally, structural rigidity of the project may arise due to excessive path dependence among nodes, creating a “screen door” to other nodes, thereby affecting the ability of the whole system to decentralize development, adaptation, and innovation. Furthermore, it was found that with the same node failure strategy, the failure rate of a node in a small group network with a high local clustering rate increased faster than that in a network without local collaboration behaviors [
60].
Results of the assortativeness calculations suggest that the form of connectivity in the TGMH project is reflected in the tendency of participants to connect to nodes with different degree values [
50]. As an example, the degree value of construction headquarters of the TGMH project is larger, while the degree value of the Central China municipal engineering design research institute is lower, indicating the existence of collaboration behaviors among nodes of different degrees in the network of the TGMH project, breaking the tendency of local grouping. A possible explanation for this phenomenon lies in the simultaneous, multi-site construction mode of the TGMH project. The various organizations of the TGMH project worked simultaneously on multiple parts of the construction site in order to maximize construction efficiency, which has enabled a greater level of collaboration among the types of organizations engaged in the project [
89]. Findings from urban networks in which various pathways are built between large cities and small and medium-sized cities in order to promote connectivity between them and achieve a radial effect that promotes economic development and accessibility substantiate this explanation [
63]. Such disassortative connection can be beneficial to network dynamics through complementary exchanges throughout the organization, greatly improving its resilience [
46]. Furthermore, a study of the sandpile cascade model, the diffusion model of distress propagation (financial contagion), finds that disassortative networks have better reactions time and, therefore, are more resilient to the process of distress propagation [
90]. By contrast, assortative networks tend to have multiple links between nodes of similar size, resulting in close links and ultimately closed structures, which significantly reduce communication [
58]. As assortative networks are more prone to epidemic/failure, transmission targeted immunization programs will increase their resilience to systemic risks [
62].
6.2. Improvement and Limitations
To investigate the factors influencing the organizational resilience of the TGMH project, a multidimensional organizational resilience assessment framework has been developed. It not only enriches the related studies of organizational resilience indicators, but also extends the measurement of organizational resilience by complex networks.
First, this paper proposes a comprehensive organizational resilience indicator system consisting of rapidity, diversity, clustering, and assortativeness, which are used to provide a static analysis of the organizational resilience of the project in regard to both the overall structure and the local structure of the network. Indicator diversity is used to describe the characteristics of its constituent nodes, in order to see how well the network responds to disruptions (such as node failures). This study provides a more comprehensive perspective when compared to an analysis solely in terms of both static and dynamic aspects [
47]. Additionally, this study provides a more comprehensive overview of the types of entities that are associated with the construction of the TGMH project than the previous study, which concentrated on relationships between contractors and overlooked other types of stakeholders [
55]. Furthermore, this paper expands the range of complex network metrics applicable to organizational resilience by examining the organizational resilience of the TGMH project from a holistic and a local perspective using seven parameters, such as network mean path, node centrality, and clustering coefficient. Instead, only four factors, such as network density, network size was used as a proxy to measure community resilience, resulting in a certain amount of incompleteness in the study [
51].
Moreover, some limitations exist in this study. An initial point to mention is that this study focused on the analysis of organizational network construction and organizational resilience assessment of the TGMH project in a single time section, without further consideration of its evolution or specific characteristics, due to the lack of a comprehensive analysis of the dynamic mechanism. The evolutionary characteristics and mechanisms of organizational resilience of construction projects based on multiple time sections may be incorporated in the future into the research framework in order to provide more systematic information about these details. Another limitation of this study is linked to the extraction of edge data used to obtain the network model. This paper simplifies the extraction process to cope with the type of collaboration relationships between organizations, i.e., it ignores the differences in edge types, which should be combined with analysis of organizational collaboration behaviors in future studies. Thirdly, despite the fact that this study found synchronization between rapidity and diversity when considering node disruption simulation, little is known regarding the relationships between rapidity, diversity, clustering, and assortativeness. A negative impact on organizational resilience may result from antagonistic relationships between specified attributes. Conversely, if the characteristics are mutually reinforcing, they may contribute to the increased resilience of the organization. Therefore, future research might consider the relationship between these attributes.
6.3. Suggestions for Enhancing Organizational Resilience
In response to emergency situations, poor organizational collaboration patterns might collapse quickly, while effective organizational collaboration patterns can effectively resist shock and achieve the construction goal. The influencing factors of organizational resilience can be summarized from the analysis of organization collaboration network of the TGMH project, which can provide useful suggestions on enhancing organizational resilience for other construction projects in emergency situations.
Firstly, overly concentrated or dispersed resources are not conducive to the advance of organizational resilience. As a consequence of the different levels of resource availability, each participating unit illustrates a different path during the project construction process. Core units, which are the main coordinators, play a critical role in enhancing integration of resources through the distribution of power and the building of a unified emergency command system. Nevertheless, this model tends to cause closed structures and leads to a single thread of communication between nodes of each unit. Consequently, it is necessary to establish a management mechanism that facilitates the shift from a hierarchical to a network-based system and establish a flat network development mechanism that is combined with complementary functions and cooperation.
Secondly, strengthening the functional integration of the network can contribute to a quicker exchange of information, thereby enhancing the organizational resilience of projects. Communication difficulties often arise in cases of information asymmetry because participants have not created a solid foundation for cooperation. A clear division of responsibilities between the respective units in a cooperative relationship drives focus on innovative inter-organizational communication and efficiency, enabling communication between nodes with low degrees and other nodes, increasing the self-adaptability of the network.
Thirdly, the rapidity of the network as well as multiple independent pathways are prerequisites for protecting the project against external interference. A collaborative and synergistic management platform specifically designed for each unit could be developed to integrate the relationships between them, provide multiple and diverse opportunities for collaboration between them, and enhance organizational resilience of the TGMH project.
7. Implications and General Conclusions
The outbreak of the COVID-19 epidemic at the start of 2020 posed a great threat to Wuhan’s public health security system, resulting in a major challenge to Wuhan’s medical supply and treatment capacity of sentinel hospitals. The TGMH project was completed in a short period of time in order to provide high-quality medical care to more than 5000 patients as well as save valuable time. Its construction experience has also prompted various construction practitioners to investigate collaboration patterns among the various organizations and their impact on organizational resilience. However, this study identifies two research questions that require further study. Firstly, what are the most appropriate indicators for evaluating organizational resilience? Secondly, what are the implications of organization collaboration behaviors on the organizational resilience of the TGMH project? To address these questions, first, this paper identifies preliminary indicators for judging organizational resilience and their corresponding complex network indicators through two rounds of literature collection. Focus group discussions with seven experts were then conducted to screen out duplicate indicators and determine the ultimate organizational resilience indicators. Secondly, a content analysis approach was applied to analyze the news coverage in the TGMH project in order to obtain data of nodes and edges needed for the network model. Utilizing these quantified data, this study relies on the network visualization tool, NET-miner6.0, to construct the network model and conduct relevant parametric analyses. Combining the results of the parametric analysis, this paper analyzed the reasons affecting the level of organizational resilience of the project and made corresponding suggestions on how to improve organizational resilience for similar construction projects. After these steps, some research conclusions are drawn in this paper, which are listed in the following:
Firstly, the organizational collaboration network of the TGMH project is composed of a central unit and multiple operational centers, with the main construction unit—the third bureau of CSCEC—responsible for work planning and resource coordination, and other government units and social service providers providing assistance. Such a centralized management model can significantly improve the efficiency of task allocation and resource scheduling in a project with tight time constraints and harsh working environment. Despite this, it should be noted that such a project management model is not necessarily suitable for all types of projects, especially those that are extremely complex.
Secondly, the process of identifying the dominant nodes in a project can be beneficial for analyzing the critical influence factors of organizational resilience. A systemic crisis can be caused when key units, such as WHPCC, which is the core organizational node of the TGMH project, fail to respond to the crisis, resulting in serious disruptions to resource transmission and the network’s resilience. The goal of project managers should therefore be to minimize the possibility of paralyzing dominant nodes. A stronger emergency response system and risk prevention mechanism will also be necessary to deal with such nodes’ risk resistance.
Thirdly, the organizational structure of the TGMH project possesses clear small-world characteristics, where each organization will have a tendency to form connections with one another based on previous cooperation experience or their own business attributes. Similar nodes will tend to form a small group, which to some extent improves the project’s organizational resilience.
Lastly, the phenomenon of single linkage paths between nodes and the grouping of nodes of similar size makes assortative networks more vulnerable to structural shocks following external shocks or disturbances. In addition, the presence of numerous and diverse heterogeneous connections can activate the dynamics of complementary network functions and directed cooperative action by reducing the path inertia between the core organizational nodes and the general nodes, which improves the overall efficiency of the network, thereby enhancing organizational resilience.
There is a theoretical contribution as well as managerial implications in this paper. In terms of the theoretical contribution, considering the fact that organizational resilience theory is typically used in business management and organizational management in general, this study extends the theory of organizational resilience to the context of construction project management, thereby enriching the management experience of construction projects in emergencies. Moreover, the paper proposes four organizational resilience assessment indicators of rapidity, diversity, clustering, and assortativeness, which has greatly enriched the dimensions of assessing organizational resilience. As for managerial implication, the study offers corresponding organizational resilience enhancement strategies in four different aspects, namely rapidity, diversity, clustering, and assortativeness. These scientific and practical management suggestions may provide valuable insights for the future analyses of other projects of similar backgrounds.
