Thimble Shoal Tunnel BAFO

Best and final offers (BAFO) are invited by July 15 from all four shortlisted bidders for the Thimble Shoal Channel tunnel being procured by the Chesapeake Bay Bridge-Tunnel (CBBT) District near Norfolk, Va.

Three foreign-led teams submitted bids on Apr. 29 for a large-diameter bored tunnel option. All were far above the estimate by Jacobs. CBBT failed to come to terms with the low bidder, Bouygues, over scope and other changes to its $1.016-billion bid, so it called for BAFOs.

SKW Tunnel Builders (Skanska/Kiewit/Weeks Marine, with WSP Parsons Brinckerhoff and Parsons) elected an immersed concrete tube option but did not submit a bid in the first round. It has been asked to prepare a bid on its immersed concrete tube proposal in the BAFO round.
