Seismic Valve (BFV) Installation – Civil & Structural Work

The contract involves the furnishing and installation of twelve-inch seismically-actuated butterfly valves at multiple reservoir locations, requiring extensive civil and structural work including vault construction, concrete placement, and necessary modifications to support the seismic valve systems. All work must comply with seismic safety standards and be integrated into existing infrastructure to ensure operational reliability during seismic events. The project demands precise coordination of structural engineering, foundation work, and utility integration to accommodate the valves and their actuation mechanisms. Subcontractors are expected to fulfill all aspects of the scope under the NAICS code 238210 for structural steel and related work, with a response deadline of August 17, 2026. The issuing entity is the City of Tualatin, Oregon, and performance will occur at multiple reservoir sites within the jurisdiction. While specific locations and point of contact details are not provided, bidders must account for site-specific challenges including ground conditions, existing utilities, and access limitations. The contract underscores the need for expertise in seismic infrastructure, concrete construction, and valve integration, with an emphasis on safety, durability, and compliance with engineering standards.
