Tunnel Construction Management for Design-Build Delivery

摘要

In recent years project owners have increasingly turned to Design-Build (DB) procurement to deliver large-diameter tunnel construction projects within compressed schedules. To capitalize on the benefits of DB delivery, the entire project team-including the construction manager-must achieve a fundamental shift in mindset and project management approach, as compared to the more traditional Design-Bid-Build (DBB) delivery. This paper provides a case history of construction management on the Blue Plains Tunnel as part of the DC Clean Rivers Project in Washington, DC and also provides key takeaways and recommendations for owners and construction managers that can be applied to other DB tunnel projects.
