Quick Summary
The US Army Corps of Engineers (USACE), Walla Walla District, is conducting a Sources Sought to identify capable businesses for the McNary Potable Water Upgrades project. This construction effort involves upgrading the potable water distribution system at McNary Dam in Umatilla County, Oregon. The purpose is to determine if this requirement can be set aside for small businesses. The NAICS code is 237990 (Other Heavy and Civil Engineering Construction) with a small business size standard of $45,000,000. Responses are due by March 24, 2026.
Scope of Work
This project entails upgrading the existing McNary Dam Potable Water Distribution System by replacing current potable water piping. The existing system must remain operational until the upgraded system is tested and commissioned. Key tasks include:
- Pipe trench excavations for new pipelines.
- Installation of valves and valve groups within subsurface concrete manholes.
- Demolition of some existing valve groups and piping.
- Connecting the new pipeline to an existing common tie-in point.
- Modifications to existing concrete vaults and provision of a new valve vault.
- Installation of two parallel 8-inch pipelines (1,400 feet) and a third 8-inch redundant line (240 feet), totaling approximately 3,040 linear feet of new pipe.
- Ancillary site work, including demolition of abandoned railroad ties, earthwork repairs, and replacement of an 852 square foot reinforced concrete slab. The total construction disturbance area is estimated at just over 1 acre, with a 0.5-acre contractor staging area.
Key Requirements & Personnel
The project requires a dedicated Site Safety and Health Officer (SSHO) with OSHA 30-hour training and a Contractor Quality Control Manager (CQC) who has completed the Corps of Engineers' Construction Quality Management for Contractors course. Both must be on-site when work is performed. The contractor must also develop and maintain a Network Analysis System (NAS) schedule and utilize the Corps of Engineers' electronic Quality Control System. All work is subject to the Corps of Engineers Safety and Health Requirements Manual (EM 385-1-1).
