The U.S. Army Corps of Engineers, Seattle District has issued SOURCES SOUGHT ANNOUNCEMENT # W912DW24R118Q to identify potential small business sources for a construction project at Chief Joseph Dam in Bridgeport, Washington. This project, titled Chief Joe Spillway Monolith Joint Sealant, aims to mitigate seepage into spillway drainage galleries, enhancing safety and maintenance. The work involves drilling, cleaning, and installing hydrophilic waterstop systems at key joints, scheduled for completion between November 2025 and February 2026. The total project cost is estimated between $1 million and $5 million.
Interested contractors must demonstrate experience in deep concrete drilling and underwater concrete repair, along with submitting a capability statement and relevant project history. The announcement seeks diverse business classifications, including Small Business, Woman-Owned, Veteran-Owned, and HUBZone firms. Responses are due by 10:00 AM PST on October 10, 2024, and must be sent via email.

The full solicitation will be released separately on SAM.gov if the project proceeds.
The Chief Joseph Upstream Monolith Joint Sealing project aims to significantly reduce leakage in the spillway drainage gallery by addressing two primary sources of water: joint drains and face drains. The approach involves sealing vertical contraction joints at specific spillway monoliths using hydrophilic waterstop cylinders, which will expand upon contact with water, creating a reliable seal. Additionally, divers will tackle open horizontal lifts on the upstream face of the dam by inserting oakum and applying an underwater epoxy sealant to stop water ingress. This work encompasses locations beyond the spillway, including replacing waterstops at upstream monolith joints. The overall effort focuses on preventing water intrusion into the dam structure, thereby enhancing stability and safety. The diver operation is estimated to cover approximately 700 lineal feet of cracks. The structured plan illustrates the project’s importance in maintaining the integrity of the Chief Joseph Dam through targeted repair and sealing efforts that adhere to federal safety standards for potable water environments.
