“…The score assigned to each cell indicates whether or not connections exist and their relative weights. In comparison to Pishdad-Bozorgi et al (2017)'s binary matrix structure, the weighted data demonstrate that connection (P1, P3) is stronger than (P1, P2), as indicated by scores of 17 and 15. Furthermore, the adjacency matrix is asymmetric and undirected.…”

“…As a result, both qualitatively derived and quantitative SNA methods are adopted. Numerous construction management SNA-based studies, including Lee et al (2016) and Pishdad-Bozorgi et al (2017), highlight five commonly used steps. Using these examples, this study follows the following steps: (a) boundary specification, (b) sampling and data collection, (c) data matrix construction, (d) quantification metrics, (e) analysis and discussion, and (f) conclusions.…”

“…Through the use of standardized metrics and concepts (Lee et al, 2017), SNA can explain the consequences and properties of a networked system (Chowdhury et al, 2011). In the construction domain, nodes have been used to represent entities such as people (Loosemore, 1998), firms (West, 2014), contractual risks (Yang et al, 2020), and project management practices (Pishdad-Bozorgi et al, 2017), just to name a few. Several of these studies have in common that they use interactions between entities to reveal connections or paths between clusters or groups involved in construction projects.…”

Previous research linked late, underpaid, and non-paid contractors to various performance issues. However, the degree to which these differences in practices enable the problem under design-bid-build contracting is unknown. To address this gap, expert interviews were used to rate 11 incompatible practices. One-mode matrices were computed by utilizing social network analysis methods. Using metrics like structural equivalence and Euclidean distance, the study established that different indexes have different connections to the payment problem. The most significant index suggests the issue is a low-cost acquisition strategy. The strategy's misaligned interests were also corroborated by the hierarchical clustering and block modelling results. The study contributes to the methodology of assessing the efficacy of existing payment default remedies, rationalization of intermediary roles, and illustrates deviations from the general contracting principles.

“…The event-based approach identifies interdependent entities based on their co-occurrence in events. An example is the interdependence of practices that results from an engineering-procurement-construction (EPC) system (Pishdad-Bozorgi et al, 2017). The relational approach involves human interactions, such as team communication.…”

Literature suggests that interdependencies may expose construction contractors to payment risks. However, prior research has tended to assume a disconnected perspective, which ignores the interdependence effect. To bridge this gap, a network of incompatible practices was built using judgments from subject matter experts in payment dispute cases in Kenya. After that, social network analysis (SNA) techniques such as Eigenvector and Lambda partitioning were used to analyze it. Ten interdependencies that expose contractors to payment risk were identified. The interdependence between the payment upon verified performance and the failure to match the work done with the amounts paid initiates and transmits most of these risks. In line with the power-law principle, fewer than 20% initiate and transmit more than 80% of the risks. This study demonstrates how economizing strategies can influence the choice of practices, complement blockchain decentralization measures, and improve the analysis of payment dispute cases.
