Overall Site


Plant Access and Security

• Dwight Road • New Security Facility • Existing Construction

Access – Sims Road


Project Features

• Contractor/CM Field Office Complex

• Contractor Laydown • Excavations, Hauling

– Scraper Route Provisions

• Onsite Traffic


Construction Workforce

• Forecasted Peak Construction Workforce

• Concurrent Projects • Contractor Site Access,

Parking, Deliveries


Project Interfaces


• Operating Plant – Construction Traffic vs.

Operations Traffic

• Access Requests – Impact to Operations

• Interconnecting Projects – Schedules impact other

contracts – Commissioning phasing


Major Equipment Procurement Alternatives


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


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


3-D Design (BIM)


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.


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.
