Progressive Design-Build in Highway Project Delivery: Promises and Pitfalls

The paper reports the results of a benchmarking study, whose purpose was to identify and articulate the current state-of-the-practice for state department of transportation (DOT) implementation of progressive design-build (PDB) contracting. PDB differs from traditional DB in that the design and construction price is negotiated after the contract is awarded. The study included a comprehensive review of the literature, a content analysis of the reported benefits, opportunities, and challenges, a content analysis of state enabling legislation, and summary-level case studies from the DOTs. The paper’s key contribution comes as it finds that PDB can be successfully implemented using a wide variety of approaches with different degrees of legislative constraints. PDB’s primary benefits are the increased transparency and collaboration that follows the open books pricing process. It provides an opportunity to negotiate risk sharing and transfer, and the major challenges to implementation revolve around demonstrating value for money without a bid price and the usual resistance to change. Keywords: Progressive design-build, project delivery, risk.
