  1. CM/GC Overview CM/GC Plan & Status Systems Description Cost Estimate Construction Schedule Risks and Challenges Summary

  2. CM/GC Plan • Why do we need a CMGC (Construction Manager & General Contractor) • SLAC does not have the in-house expertise to independently manage a project of this magnitude

  3. CM/GC Plan • SOW for CM/GC has been developed and continues to have the highest priority in the CF group as largest stand-alone procurement in the LCLS project • Currently being reviewed by SLAC SO DOE • Comments being updated as we speak • Once approved by SLAC SO DOE, the plan is to submit to DOE Headquarters for approval (Chicago → DC) • Once plan is approved, there will not be a need to go back for multiple review and approval of bid packages

  4. CM/GC Plan – cont’d Advertisement placed in construction periodical – ENR Magazine Jan/Feb • Advanced Procurement Plan (APP) has been written and continues to be updated as necessary (signed copy on LCLS website) Meeting planned Milestones are crucial!

  5. CM/GC Plan – cont’d • CM/GC services will be solicited as firm-fixed price contracts • Phase 1 – preconstruction services • Phase 2 – construction services of underground and major excavation effort, and construction services of above ground buildings • CM/GC Award 6/30/05 • CM/GC qualifications – partial list • Technical competence • Similar previous experience • Successful history using second and third tier subcontractors • Financial strength

  6. CM/GC Plan – cont’d • Outstanding safety record • Experience Modification Rate (EMR) <.81 • EMR 1.0 indicates that a company submits injury claims that are considered average among their industry group • EMR > 1.0 indicated that the company files more claims than other similar companies • EMR<0.81 indicates that the company had filed fewer claims than those compared against similar companies • Injury frequency and severity rates • Safety Program evaluation and evaluations of the key personnel • OSHA citation history • References from previous projects • Evaluation of the contractors’ integration of safety into their work practices LCLS has decided to place all contractors working on projects to have an EMR of <.81, go no-go

  7. CMGC P3 Schedule

  8. CM/GC Phase 1 Effort • Phase 1 – preconstruction activities to include: • Provide effective overlap period and oversight of effort during Title II • Estimates during Title II • CPM Schedule • Identify lead-time for critical items • Design coordination • Constructability reviews • Value Engineering reviews • Site investigation

  9. CM/GC Phase 1 Effort – cont’d • Develop Project Management Plan (PMP) • Construction Management Plan – outlines project scope, organization, and specific approach to accomplish project • Project Safety Plan – project specific identifying job hazards, safety performance and individuals responsible for project safety • Procurement Plan – identifies systems, methods and procedures for solicitation to subcontractors • Quality Control and Assurance Plan – method of controlling time, cost and quality of various management tasks specific to the project

  10. CM/GC Phase 1 Effort – cont’d • Develop construction bid packages • Develop list and contact potential bidders • Develop prequalification criteria • Solicit bids • Recommend award to SLAC for approval of subcontractor • Award contract to subcontractors

  11. CM/GC Phase 2 Effort • Phase 2 – CM/GC shall provide all materials, labor, and services required to construct the Project • All general conditions including field personnel, office staff, temporary offices, temporary construction, safety implementation, construction equipment, coordination of all subs, project administration, construction waste management, commissioning

  12. Below Grade Plan Beam Transport Hall Near Hall Undulator Hall XRTDT Far Hall

  13. New Facilities (below grade) • Beam Transport Hall – 227m long above grade facility to transport the electron beam through the existing RSY • Undulator Hall – 175m long underground tunnel housing undulators and ancillary equipment • Central Lab Office Complex – office facility to house ~ 300 LCLS researchers, engineers, technicians, administrative staff and visiting experimentalists • Far Experimental Hall – underground cavern/tunnels to house 3 experimental hutches, prep and shop space • Electron Beam Dump – 40m long underground facility used to separate the electron and x-ray beams • Front End Enclosure – 30m long underground facility to house various diagnostic equipment in support of the photon beam • Near Experimental Hall – underground facility whose primary function is to house 3 experimental hutches, prep and shops • X-Ray Transport & Diagnostics Tunnel – 250m long underground tunnel used to transport photon beams from NEH to FEH

  25. CF FY Total Estimated Cost CMGC is responsible for ~$500K for Phase I (Award CMGC thru March 06) and $59.5M for Phase II (Mar 06 thru 08)

  26. LCLS CF Construction Schedule • Added additional time for CM/GC procurement phase: • DOE approval and CM/GC subcontractor bidding phase • Major construction phase FY 06 at 30 months duration • Beneficial Occupancy dates are key to technical system interfaces • Site-work at NEH is key!

  27. Title-II Draft Schedule Interactive Planning session is scheduled for April 13,14 (6/05) CMGC has real value added input early during design phase This is essentially JE 100% stage

  28. Risks and Challenges Construction Safety All construction activities to comply with Federal and State environmental, safety, health and building codes Subcontractor activities In-house activities SLAC will approve construction safety program prior to start of construction Enhanced construction program is a must Special consideration is being addressed Tunnel construction RSY due to the congestion in the area

  29. Risks and Challenges – cont’d Bay area construction market Materials Labor Schedule concerns Annual lab shut-down periods Schedule for site characterization & remediation FFTB decommissioning On-site support

  30. Summary Confidence is high for the successful implementation of the model chosen as it has already been proved at LBNL Molecular Foundry CMGC holds the paper Actual cost will be determined by competitive bids from subcontractors Total estimated pricing established by SLAC
