dc.description.abstractThe complex and challenging process of construction supply chain management can involve tens of thousands of engineered components, systems, and subsystems, all of which must be designed in a multi-party and collaborative environment, the complexity of which is vastly increased in the case of megaprojects. A comprehensive Advanced Construction Supply Nexus Model (ACSNM) was developed as a computational and process-oriented environment to help project managers deal efficiently and effectively with supply chain issues: fragmentation, resource shortages, design delays, and planning and scheduling deficiencies, all of which result in decreased productivity, cost and time overruns, conflicts, and time-consuming legal disputes. To mitigate the effects of these difficulties, four new prototype systems are created: a front-end planning tool (FEPT), a construction value packaging system (CVPS), an integrated construction materials management (ICMM) system, and an ACSNM database. Because these components are closely interdependent elements of construction supply nexus management, the successfully developed model incorporates cross-functional integration. This research therefore effectively addresses process management, process integration, and document management, features not included in previous implementations of similar models for construction-related applications. This study also introduces new concepts and definitions, such as construction value packages comprised of value units that form the scope of value-added work defined by type, stage in the value chain, and other elements such as drawings and specifications. The application of the new technologies and methods reveals that the ACSNM has the potential to improve the performance and management of the enterprise-wide supply chain. Through opportunities provided by our industry partners, Coreworx Inc. and Aecon Group Inc., the elements of the developed model have been validated with respect to implementation using data from several construction megaprojects. The model is intended to govern current supply nexus processes associated with such megaprojects but may be general enough for eventual application in other construction sectors, such as multi-unit housing and infrastructure.en
