LCLS-II Photon Infrastructure CP3B Structural Construction

This is a Request for Proposal (RFP) for a firm-fixed-price subcontract for the LCLS-II Photon Infrastructure Construction Package #3B Architectural and Structural Project. The Laboratory campus (work site) is located in Menlo Park, California approximately two miles southwest of Stanford University. This is design-bid-build project and the University will be using a best-value trade-off source selection method in accordance with SLAC National Accelerator Laboratory Policies, Procedures and General Terms and Conditions for Fixed-Price Construction Subcontracts. PROJECT OVERVIEW SLAC National Accelerator Laboratory (SLAC) is seeking qualified and experienced Concrete or equivalent subcontractors to perform architectural and structural construction services for the LCLS-II Photon Infrastructure Construction Package 3B Project. The individual awardee shall complete the construction work within the requirements of the Subcontract, on schedule as defined in this Statement of Work. The Awardee is required to coordinate with LCLS-II Field Construction Manager and other Subcontractors working directly in these areas for LCLS-II, and the Subcontractor is required to collaborate with SLAC Management and Technical representatives and other area/site subcontractors to provide the highest quality, sustainable facility for the LCLS-II Project; and meet or exceed the requirements in the Project Construction Package 3B Request for Proposal documents (i.e. procurement subcontract proposal; project specifications; and project drawings). The Awardee will be responsible to provide qualified skilled labor and supervision, services, materials, equipment and tools to meet the requirements of the statement of work. PROJECT SCOPE The Photon Infrastructure Construction Package 3B Project consists of requirements for work within the Linac and Gallery Sectors 11-30 (S11-30); Beam Switchyard (BSY), Beam Transport Hall (BTH); Undulator Hall (UH); Electron Beam Dump (EBD); and Front End Enclosure (FEE) areas of the existing Accelerator, located at SLAC National Accelerator Laboratory, 2575 Sand Hill Road, Menlo Park, CA 94025. ARCHITECTURAL and STRUCTURAL WORK SUMMARY Base Work - EBD: Enlarge the existing Magnet Equipment Pit, Sump Equipment Pit, and Beamline Trenches that connect the Pits together. Includes demolition of concrete facing surfaces and associated rebar. Re-build new facing surfaces with doweled rebar and equal strength concrete to new Pit & Trench dimensions. All demolished materials to be disposed, after SLAC testing and release. Base Work - North and South Research Yards: Supply and Install all New PPS Zone Fencing with the North and South Research yards running parallel to the BTH walls. Includes return fence sections and sections of fencing that are mounted adjacent to the Service Buildings 911 and 913. New fencing is a high grade, heavy gauge metal 8'-0" fence, which requires new footings and access gates as detailed in the Architectural drawings. Fence to have conduit raceways added for SLAC PPS Controls and be properly grounded as shown on Electrical drawings. Base Work - Undulator Hall: Floor modifications: Install additional floor depressions, as shown that match existing depressed areas under South side Undulator stands. Fill portions of existing floor depressions with reinforced grout to allow bearing surface Undulator transport equipment. Bid Option 1: Architectural/Structural work associated with the Undulator Transport through the BTH North "Plug" Wall. 1) Removal of the existing North "Plug" wall pre-cast concrete panels. Store panels vertically, along exterior of BTH structure, for re-installation. 2) Construct new exterior concrete pad and fabricate & install steel bridge materials for level Undulator transport path from exterior to interior of BTH. 3) After Undulator transport is complete, remove steel bridge materials (return to SLAC); and re-install and seal Plug Wall along with associated weather proof flashing. Bid Option 2 (Photon Systems): Architectural/Structural work in the Electron Beam Dump (EBD) associated with the Removal/Relocation & Replacement of the Beam Dump Shielding Steel, and Cast in Place Concrete Wall (at FEE wall), and Installation of Interior Pre-Cast Concrete Retaining Wall. SLAC to provide steel shielding, pre-cast concrete, and associated steel support brackets and framework. Contractor to provide the concrete to be poured in step 3. Detail Drawings will be provided later through an amendment. 1) Removal of existing South Dump Shielding Steel plates and storage inside tunnel for re-use. Steel plates that will not be reused to be moved outside the tunnel. 2) Removal of South Dump Concrete material. 3) Install (Pour) concrete shield blocks in place between Pit shielding and FEE Wall. 4) Install steel plate shielding, pre-cast concrete shieling blocks within steel stack, and dumps. Note that some shielding needs to be placed before installing the dumps, then the rest of the shielding is to be installed. 5) Install New Pre-Cast Concrete Plate Retaining Wall with associated steel support brackets and framework.
