Abstract

This study analyzes the feasibility of applying Integrated Project Delivery (IPD) principles to construction subcontracts through a comparative analysis of a traditional lump-sum contract and a hypothetical IPD-based scenario. The bidding, award, execution, and closeout phases of a road impact mitigation project are examined to identify gaps and assess the impact of a collaborative approach on business profitability. The results suggest that implementing IPD could optimize the distribution of costs and benefits, allowing clients to maximize their savings and subcontractors to improve the predictability of their margins. However, challenges related to risk management and adaptation to new contractual dynamics are evident. Finally, the study highlights the potential of IPD to strengthen business relationships and foster sustainable long-term agreements.
