Sack Dam Bypass Project:

Critical Infrastructure for River Reformation

Location: Dos Palos, CA

Agency: U.S. Department of the Interior

General Contractor: NW Construction Inc.

Building Dimensions: 28' x 38' PEMB

Supporting Ecological Restoration

The Sack Dam Bypass Project in Dos Palos, California, is a significant civil works initiative spearheaded by the U.S. Department of the Interior. Focused heavily on river reformation and ecological restoration, the project is designed to restore natural aquatic habitats and ensure the safe passage of local wildlife.

While the vast majority of this ambitious project involves complex civil and earthwork operations, it relies on a single, vital vertical structure to anchor the site. This custom fish bypass facility provides essential administrative workspace and secure equipment storage for ongoing on-site operations and monitoring.

Streamlined PEMB Procurement and Engineering

To house these critical functions in a demanding environment, a 28' x 38' Pre-Engineered Metal Building (PEMB) was selected for its durability and rapid assembly.

Navigating the rigorous standards of a Department of the Interior project requires precision. Similar to our successful deployment on the Alhambra project, RPM Team took a comprehensive, hands-on role in managing the procurement and engineering of the metal building. Rather than treating the structure as a standard material order, our team managed the entire lifecycle of the PEMB—from initial manufacturer coordination and structural engineering integration to expertly navigating the complex federal submittal and approval processes.

By actively managing the supply chain and engineering constraints upfront, RPM was able to bypass typical procurement delays. We worked seamlessly alongside the General Contractor, NW Construction Inc., to ensure that the building arrived on-site accurately engineered, fully coordinated, and ready for immediate erection. This proactive approach kept the vertical construction off the critical path, allowing the broader civil and river reformation efforts to proceed without interruption.
