CUIR Project Opportunity
Critical Utilities Infrastructure Revitalization
SLAC’s Critical Utilities Infrastructure Revitalization Project is a construction capital improvement 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 systems were installed in the 1960s when the laboratory was initially built.
The original utility systems were not designed to support the experimental parameters needed for science 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.
The project consists of three subprojects. SLAC aims to efficiently execute utility improvements that align with lab priorities while minimizing operational downtime and occupant impact.
CUIR Opportunities
CUIR received DOE Critical Decision 3A (CD-3A) approval in May 2023. The first subproject, Subproject 1 - Critical Electrical System Improvements, is approaching Performance Baseline Approval (CD-2) and Start of Construction (CD-3) in Summer 2025. Moreover, the preliminary design for the second subproject, Subproject 2 - Critical Civil Utilities Replacement and Upgrades, will commence in 2025.
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 long-lead electrical equipment is acquired as Government Furnished Property (GFP) and will be provided to Subproject 1 contractors for installation.
The five construction packages are:
- Package A: Linac Power Distribution System (Design-Build)
- Package B: Master Substation Building Expansion (Design-Build)
- Package C: 230kV Transformer Replacement (Design-Build)
- Package D: Substation K-5B and Sector 4 Switchgear (Design-Bid-Build)
- Package E: SCADA Hardware at IR-12 (Design-Bid-Build)
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 are expected to start in Winter 2025.
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 create significant deformation of the linac housing (tunnel). SP2 scope aims to stabilize the SDs' drainage and erosion along the linac. In addition, corroded water lines and inoperable water valves from sectors 7 to 30 will be replaced, and new meters will be added 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, including metering.
- North Campus Utilities: Replace failing domestic water and sewer lines serving B081, B024, B025, & B035, including metering.
