  2. Cost to Go at WBS Level 3

  3. Basis of Estimate - ETC

  4. Contingency Analysis • CONSTRUCTION CONTINGENCY • QUALITY OF DESIGN • 2-5 % OF CONSTRUCTION COST – USE 3% • CONSTRUCTION MANAGEMENT • 3-7 % OF CONSTRUCTION COST – USE 4% • OWNER-INITIATED CHANGES • 5-? % OF CONSTRUCTION COST – USE 8%

  5. CONTINGENCY ANALYSES

  6. CF Construction Phase • Cost/Schedule Performance • CPI = 1.03 • Title III Awarded Amount: $63,972,680 • Obligated Funds: $10,592,451 • SPI = 1.01 • NTP: 01Aug06 • Commence Sitework: 01Sep06 • Beam Line Beneficial Occupancy: 8Feb08 • Contract Close-out: 18Aug08 • Contract Administration • Submittals • Received: 32 • Approved: 18 • RFI: • Received: 55 • Closed: 55

  15. CF Construction Organization

  16. Issues (and Mitigation) • Encountering Remnant Utilities • Surveys to locate active utilities • Coordination with CEF to review historical records • Trenching to locate abandoned and unmapped utilities • Site Security and Safety • Signing and Fencing • Communication with SLAC residents • All-hands Bulletin • Active Enforcement • Construction Delays • Mitigation Plans in advance • Work-arounds and Re-sequencing • Contingency Plans

  17. Issues (and Mitigation) cont. • CLOC De-scoping • Thorough Scrubbing of CLOC scope items • Definition of Scope Reduction Interfaces • Coordination and Negotiation with CM/GC • Technical Systems Construction Tolerances • Definition of Needs in concert with Tech. Systems • Coordination with Trade Contractor to meet spec. • Preparation of Work Plans to accomplish goals • Increasing Market Costs • Maximize Forward Pricing • Minimize Change Orders • Use Volume Purchasing where practical • Disputes and Claims • Quickly Address Claims • Implement Dispute Review Board Process • Prepare and Use an Issues Resolution Ladder
