About this file
This document package includes plans and specifications for the Dexter Adult Fish Facility Upgrades project. The U.S. Army Corps of Engineers, Portland District is soliciting proposals to upgrade major features and systems at the Dexter Fish Facility to meet criteria set by the National Marine Fisheries Service. Upgrades include improvements and additions to the fish ladder, diffusion chamber, and adult fish facility. The period of performance is anticipated from March 2023 to November 2026 with an estimated construction value between $25-100 million. The NAICS code is 237990 for other heavy and civil engineering construction, and the project has an unrestricted, full and open competition set aside. The HUBZone price evaluation preference will apply.
