Revised Proposals Received for Parallel Thimble Shoal Tunnel

On July 15, the Chesapeake Bay Bridge and Tunnel Commission announced that revised technical and price proposals had been received from all three teams in the competitive procurement to construct a new parallel tunnel at the Thimble Shoal Channel.

The new tunnel will double capacity at one of two tunnel bottlenecks on the 23-mile-long Chesapeake Bay Bridge Tunnel (CBBT), which provides a fixed link between Virginia’s eastern shore and the Norfolk and South Hampton Roads region on the USA’s East Coast.

On May 27, 2016, the Commission invited each of the three teams that had submitted fully compliant proposals by the original due date of April 29, 2016, to submit revised proposals for a re-scoped Project.

The District determined that the best interests of the Project would be served by re-engaging with all of these shortlisted teams to re-scope the Project after all of the original price proposals exceeded the cost estimate for the Project.

Revised technical proposals were submitted on July 12, 2016, and all three teams were deemed to have submitted a technically acceptable solution for the construction of the Project. The revised price proposals submitted on July 12 by the teams were as follows:

The re-scoping of the Project was focused solely on the reduction of costs by reducing or eliminating unnecessary elements of the Project without compromising the quality or performance specified in the Technical Requirements of the RFP documents.

Specifically, (1) scope changes that would increase the long-term cost of operating and maintaining the tunnel were not considered; (2) re-allocation of construction risks between the CBBT and the Design-Build Teams were not considered; and (3) changes to the Comprehensive Agreement, or contract, were not considered.

Over the next twelve calendar days, the District Project Management Team will finish the evaluation of the revised proposals to consider a recommendation for the Commission to award the Project at a special called meeting on July 27, 2016.
