Pier Protection of the Delaware Memorial Bridge, Wilmington, DE

The Delaware River & Bay Authority (DRBA), and its design engineers for this project, S.T. Hudson Engineers reached out for independent cost estimating (ICE) support on their ship collision protection structure project. The project will construct eight 80-foot diameter sheet pile cells filled with aggregate that are designed to protect the 71-year-old substructure of the Delaware Memorial Bridge across the Delaware River. The project was previously competitively bid, and bids received were 35 to 50 percent over the engineer’s estimate, and the project budget. DRBA decided to utilize the CMGC process, selected their most qualified contractor and ICE began helping the team optimize project scope and developing an independent cost estimate alongside the selected contractor.

With the optimized scope and design from S.T. Hudson, the team has been able to significantly reduce the project cost and will likely deliver the project on time. This project was a fast-paced CGMC project, with only 12 weeks of reconciliation and negotiation.
