About this award
ENDIST Seattle awarded a $1,143,312.85 firm fixed-price definitive contract to AMS Industrial LLC for repair of steel liner infrastructure at Mud Mountain Dam on December 27, 2025, under a total small business set-aside. The work is to be completed by November 23, 2026.
AMS Industrial is a small disadvantaged business. The contract calls for dewatering, sediment removal, steel plate installation, welding, and epoxy grouting of the 30-year-old steel liner in the tunnel entrance, which protects the tunnel structure from damage and regulates flood flows. The performance window is restricted to July 20, 2026 through September 30, 2026, with work hours limited to 6:30 AM to 4:00 PM, Monday through Friday. Contractors must provide specialized equipment including dewatering systems, tunnel lighting, ventilation systems, and all materials for complete restoration.
Place of performance is Enumclaw, Washington. The originating special notice, posted July 11, 2025, with a July 30, 2025 deadline, announced an August 13, 2025 Industry Day and site visit at the dewatered tunnel—the sole opportunity for contractors to view the site before bidding, as the tunnel would remain fully watered during the bidding period.
