Critical Utilities Infrastructure Revitalization
SLAC’s Critical Utilities Infrastructure Revitalization Project is a construction capital improvement project aimed at empowering 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 develop utility infrastructure to provide reliable and sustainable operations, enabling mission readiness and enhancing the impact of Department of Energy (DOE) scientific programs.
CUIR is 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 received DOE Critical Decision 3A (CD-3A) approval in May 2023. SLAC is currently executing Subproject 1, Critical Electrical System Improvements, the first of three subprojects in this multi-year effort.
Critical Electrical System Improvements
Subproject 1 includes:
- Construction of a new substation construction
- Constructing and installation of new 12 kV feeder cable pathways
- Expanding SLAC’s Master Substation control building
- Replacing two major 230 kV transformers inside the master substation
- Installing multiple new switch gears
These electrical utility improvement plans have many physical interfaces with existing electrical systems that need to stay energized as long as possible to reduce impacts on the lab’s science mission.
SLAC seeks a local and experienced integrated design-build subcontractor to deliver CUIR’s Subproject 1 successfully. The preliminary procurement and construction timeline is below.
This schedule is subject to change.
Long Lead Time Items
Government Furnished Property
To reduce supply chain and scheduling impacts on Subproject 1, SLAC is procuring critical long-lead electrical equipment.
This equipment is considered Government Furnished Property and will be provided to the future subcontractor for installation, including:
- High- and medium-voltage transformers
- 12 kV cables
- Medium-voltage switch gears
