Balancing Innovation, Risk, and Cost: Innovative Procurement Approach for Sewer Tunnel Rehabilitation

摘要

In an industry where innovation, risk, and cost are intertwined, Contract 4 of the $160 millionrnOMID sewer rehabilitation program presented an especially difficult problem: How to attain a competitivernprice for tunnel lining product, when the project conditions and technical requirements severely limit choices.rnWhile unique and complex underground challenges are often solved by including a sole-source requirement inrnthe bidding documents, the design team for this project implemented a different approach. The final result wasrna winning bid that used fewer access points, included a very high quality lining system, and was 28% belowrnthe Engineer’s cost estimate.
