ALCOSAN is soliciting Letters of Interest and Statements of Qualification (collectively, “Submittals”) from Professional Engineering firms to perform the Allegheny River Tunnel (ART) Final Design Consulting (FDC) Services. The project will build upon the work performed by the Preliminary Planning team, as well as other work completed to date on the Ohio River Tunnel (ORT) and ART-Near Surface Package 6 (ART-NSF6), to advance the ART and associated drop shafts, regulators, outfalls, and consolidation sewers to a final design.

The ART FDC will perform final design for the ART and the associated conveyance systems, excluding the near surface facilities associated with point of connections A-72 through A-78. The final designer will work closely with the Tunnel Program Manager Consultant (TPMC) and ART-NSF6 FDC to coordinate connections to the ORT, ART-NSF6 facilities at A-72, and future connection with the Monongahela River Tunnel (MRT).
