Solicitation # W912EF27RA001
The U.S. Army Corps of Engineers, Walla Walla District, intends to issue a Construction Indefinite-Delivery, Indefinite-Quantity (IDIQ) Multiple-Award Task Order Contract (MATOC) on approximately November 30, 2026. This contract will provide construction services for the renovation and upgrade of life-safety systems at large, remote hydroelectric powerhouses within the Northwest Division, primarily focusing on the Walla Walla District projects at McNary, Ice Harbor, Lower Monumental, Little Goose, Lower Granite, and Dworshak, with potential work extending to the Seattle and Portland Districts across Washington, Oregon, Idaho, and Montana. The government anticipates awarding up to four MATOCs, with one to two reserved for qualified small business concerns. The aggregate shared contract capacity is estimated at $99 million, featuring a 36-month base period and two 24-month option periods, with individual firm-fixed-price task orders reaching up to $25 million. The scope of work involves upgrading life-safety systems in facilities ranging from 75,000 to 420,000 square feet and 5 to 11 stories. Key industrial construction elements include the installation and modification of fire detection and mass notification systems, various fire suppression systems, smoke control and HVAC digital controls, architectural fire barriers, emergency lighting, and electrical power distribution. Due to the nature of the environment, contractors must adhere to rigorous lockout tagout procedures and manage challenges such as working near high-voltage equipment, operating in continuously active industrial settings, and accessing multiple underground levels. Additionally, fire alarm designers and installers must hold NICET Level III or IV certification. Task orders will be awarded based on an evaluation of price and past performance, potentially including other non-price factors as specified in each request for proposal.
