About this opportunity
The National Park Service (NPS) is soliciting proposals for the rehabilitation of the El Portal Wastewater Treatment Facility (WWTF) and Administrative Camp in Yosemite National Park, California. The project involves fully replacing the 45-year-old, undersized wastewater treatment facility, which serves Yosemite Valley, El Portal, and adjacent communities, and rehabilitating the former El Portal Trailer Village. The solicitation, numbered 140P2025R0008, seeks a comprehensive construction contract to upgrade electrical systems, replace failing infrastructure, and improve treatment processes and facility operations. Proposals will be evaluated using a best value tradeoff approach, with technical factors deemed more important than price. The formal question submission deadline is November 18, 2024, with a final cut-off for questions on December 16, 2024, and proposals are due by January 6, 2025 at 2:00 PM Pacific Time.
The contract has no specific set-aside designations and will be awarded through full and open competition. The estimated contract value ranges between $150 million and $200 million, with a performance period of 1,460 calendar days. The project will be constructed under a single prime contract and includes a base bid with four separately priced option line items. The place of performance is the El Portal facility in Mariposa County, California, where the contractor will replace major components including electrical service, switchgear, motor control center, and distribution systems. The rehabilitation will also convert the former trailer village into RV sites for construction workforce housing and a contractor staging area, with plans to implement best practices for campground design and natural resource protection. Key personnel requirements include positions for a Project Manager, Superintendent, SCADA Lead, Plant Commissioning Lead, and Safety Manager.

YOSE 196416 Rehabilitate El Portal Wastewater Treatment Facility and Administrative Camp
The work of this contract is for the construction of: YOSE 196416 Rehabilitate El Portal Wastewater Treatment Facility and Administrative Camp in Yosemite National Park, El Portal, Mariposa County, California.
This project will rehabilitate the 45-year-old El Portal wastewater treatment facility (WWTF), the largest in the NPS, and the sole wastewater treatment service for the Yosemite Valley, El Portal, and adjacent communities. The existing facility features an undersized two-story arrangement with limited access points and failing systems. It is not feasible to modify the existing plant to accommodate required improvements to lab and office space, make room for more effective treatment process infrastructure, or provide adequate space for system operation and maintenance activities. Replacement components are difficult to procure or are no longer manufactured due to the age of the existing plant, resulting in the need to fully replace the electrical service, switchgear, motor control center, and distribution systems.
This project will also rehabilitate the former El Portal Trailer Village (Administrative Camp) to be used as RV sites for construction workforce housing and a contractor staging area. NPS plans to rehabilitate or replace infrastructure and utility systems to support the RV sites. NPS will implement its best practices for RV-based campground design to arrange the RV sites to improve natural and cultural resource protection.
