Description

This Draft Request for Proposal (RFP) is a Sources Sought Notice to identify General Contractors (GC) who are capable of completing the planned construction of the Cryomodule Repair and Maintenance Facility (CRMF) Cleanroom and Ultra-Pure Water (UPW) System to support the future repairs to the LCLS-II and LCLS-II-HE cryomodules.

This is not a solicitation for proposal, and no award will be made from this Notice. SLAC intends to issue a formal solicitation later based on responses from this Source Sought Notice.

The site for the Cleanroom install will be inside the new CRMF building and is located North of the existing Linac Sector 11, along the North Access Road, adjacent the Sector 10 Adit Road located at the SLAC National Accelerator Laboratory, 2575 Sand Hill Rd, Menlo Park, CA 94025. This project is directly funded by the DOE's Office of Science.

The DRAFT RFP package attached consists of construction documents outlining the administrative and technical specifications and drawings pending approval by SLAC’s Building Inspection Office (BIO). The final documents will be used by construction subcontractors to assist in preparing a Firm Fixed Price Proposal.

PLANNED SCOPE AND DESCRIPTION OF SERVICES
