CUIR Project Opportunity
Critical Utilities Infrastructure Revitalization
SLAC’s Critical Utilities Infrastructure Revitalization Project is a capital improvement construction project that aims to empower SLAC National Accelerator Laboratory (SLAC) to continue its research mission and objectives for years to come.
The CUIR project aims to modernize SLAC’s utilities infrastructure. Many of these original systems were installed in the 1960s when the laboratory was initially built and were not designed to support the experimental parameters needed for scientific research today and in the future.
CUIR will revitalize utility infrastructure to provide reliable and sustainable operations, enabling mission readiness and enhancing the impact of Department of Energy (DOE) scientific programs.
CUIR is a project directly funded by the DOE's Office of Science and consists of three subprojects aimed at efficiently executing utility improvements that align with lab priorities while minimizing operational downtime and occupant impact.
Upcoming CUIR Project Opportunities

Construction | Subproject 1 - Package C: 230kV Transformers Installation | Spring/Summer 2027 |
Third Party Inspectors | Various Scopes | Fall 2026 to 2029 |
CUIR Opportunities
CUIR received DOE Critical Decision 2/3 approval for Subproject 1 - Critical Electrical System Improvements in June 2025. Since then, two major electrical scopes were executed while other scopes progressed in design in preparation for construction procurement. Moreover, preliminary design for the second subproject, Subproject 2 - Critical Civil Utilities Replacement and Upgrades, has started.
SUBPROJECT 1
Critical Electrical System Improvements
Subproject 1 includes five construction packages (Packages A, B, C, D, and E) and six long lead electrical equipment items. The Government will acquire the long-lead electrical equipment as Government Furnished Property (GFP) and provide it to Subproject 1 contractors for installation.
The five construction packages are:
- Package A: Linac Power Distribution System (Awarded)
- Package B: Master Substation Building Expansion (Design-Bid-Build)
- Package C: 230kV Transformer Replacement (Design-Bid-Build)
- Package D: Substation K-5B and Sector 4 Switchgear (Awarded)
Package E: SCADA Hardware at IR-12 (Awarded)
The Subproject 1 electrical utility improvements have many physical interfaces with existing electrical systems that need to stay energized as long as possible to reduce impacts to the lab’s science mission. Construction activities for Subproject 1 began in February 2026.
SUBPROJECT 2
Critical Civil Utilities Replacement and Upgrades
Critical Civil Utilities Replacement and Upgrades (Subproject 2) include storm drain, domestic water/fire-fighting water, and sanitary sewer system replacements throughout the entire SLAC campus:
- Linac Storm Drains and Domestic Water: Four SDs crossing under the linac between sectors 0 and 25 could fail and significantly deform the linac housing (tunnel). SP2 scope aims to stabilize the SDs' drainage and erosion along the linac. In addition, replace corroded water lines and inoperable water valves from sectors 7 to 30, and add new meters to improve operational efficiency.
- Research Yard Utilities: Replace corroded storm and domestic water underground pipes, including metering.
- Central Campus Utilities: Replace failing domestic water and sewer lines serving B040/B040A, B044, B050, B057, and B084, inclusive of metering.
- North Campus Utilities: Replace failing domestic water and sewer lines serving B081, B024, B025, & B035, inclusive of metering.
