Improving the Collaboration between Main Contractors and Subcontractors within Traditional Construction Procurement

Abstract EN

The inability of subcontractors/specialist contractors to contribute meaningfully to the construction process under the traditional construction procurement hampers the possibilities of improving value on projects and their integration with the rest of the supply chain.

In particular, the main contractors and subcontractors in traditional construction procurement projects pursue their self-interests to such an extent that collaborative working has been impossible to achieve.

In this research, qualitative and quantitative approaches were used to collect data to explore the problems at the root of the main contractor-subcontractor relationship.

Intending to derive innovative ideas to reinvent the delivery process of traditional construction procurement, the principles of integrated project delivery (IPD) and the last planner system (LPS) were studied to seek useful ideas that can be employed to improve collaboration between main contractors and subcontractors.

A high point of contention is the debate on the managerial competence of subcontractors; nevertheless, hope is expressed at the possibility of improving collaboration between the main contractor and subcontractor within traditional construction procurement work environment.
