30 Overall Site

31 Plant Access and Security Dwight Road New Security Facility Existing Construction Access Sims Road

32 Project Features Contractor/CM Field Office Complex Contractor Laydown Excavations, Hauling Scraper Route Provisions Onsite Traffic

33 Construction Workforce Forecasted Peak Construction Workforce Concurrent Projects Contractor Site Access, Parking, Deliveries

34 Project Interfaces

35 Operating Plant Construction Traffic vs. Operations Traffic Access Requests Impact to Operations Interconnecting Projects Schedules impact other contracts Commissioning phasing

36 Major Equipment Procurement Alternatives

37 Best Value Selection For Major Equipment Procurements Procure equipment based on their long-term costs In most cases, lowest bid cost selection will apply For equipment with significant variations in operational costs, alternative procurement options will be considered

38 Alternative Procurement Options Bids based on present worth analyses by Contractor Bids based on equipment pre-selected by the District Bids based on pre-purchased equipment by the District Bids based on pre-purchased equipment subsequently assigned to the contractor

39 3-D Design (BIM)

40 Objectives of 3-D Design Allow stakeholders to visualize finished facilities (layouts, access, etc.) during design development. Utilize clash detection to identify and eliminate conflicts both within and between projects. Efficiently manage large volume of asset data, including tag numbers, asset parameters, and maintenance data. Manage changes to contract documents during construction and commissioning phases.

41 Potential Contractors Use of 3-D Design Documents 3-D model files may be made available during bid phase, with disclaimer. BIM files may be available for 4-D (schedule) and 5-D (cost) management. Responsibility for maintaining model files to reflect changes, and as-built conditions, during construction TBD. Use of asset database for submittals (shop drawings, O&M information, etc.) TBD.
