About this file
This document package includes construction plans and a federal contract solicitation. The solicitation seeks a firm-fixed-price construction contract valued between $10-25 million to upgrade the electrical power and controls systems at McNary Lock and Dam in Umatilla/Benton Counties, Oregon. The scope of work involves installing new feeders from the powerhouse to the navigation lock; replacing 480-volt distribution equipment; adding cameras; repairing grounding; and upgrading controls for gates, valves and a bascule bridge. The contractor must complete all work by June 18, 2024. A 20% bid bond or $3 million bond is required, as well as 100% performance and payment bonds. The NAICS code is 238210 and small business size standard is $16.5 million. A pre-bid site visit will be offered approximately two weeks after posting. The construction plans show details for new transformers, conduits, circuit breakers and other electrical infrastructure to support the upgrades.
