As construction projects grow in complexity, integrating digital technologies with collaborative delivery models is crucial for improving project outcomes. This study explores the interaction mechanisms between integrated project delivery (IPD) and digital management platforms (DMP), addressing how IPD enhances DMP functionality and the moderating role of project complexity (PC). It aims to provide theoretical insights and practical strategies for optimizing digital construction management.
This research employs structural equation modeling (SEM) and multi-level moderation analysis to examine the coupling relationship between IPD and DMP. A survey-based empirical study was conducted, analyzing the mediating roles of information symmetry (IS) and risk-sharing mechanisms (RSM), as well as the moderating effect of PC on these relationships.
The results indicate that IPD significantly enhances DMP performance by improving information transparency and resource integration. IS and RSM partially mediate this relationship, collectively amplifying IPD’s impact on DMP. PC positively moderates the direct effect of IPD on DMP, strengthening collaboration under high complexity. However, it negatively moderates the mediating effect of RSM, suggesting diminishing effectiveness of risk-sharing in complex environments.
This study advances theoretical understanding by systematically linking process-driven project delivery with technology-driven platforms. It provides practical insights into optimizing digital collaboration frameworks, refining risk-sharing mechanisms, and adopting complexity-adaptive strategies. The findings contribute to both digital construction management and project delivery efficiency, supporting industry-wide digital transformation.
