13 FINAL DESIGN & CONSTRUCTION PROCUREMENT ACTION PLAN Planned procurement for final design and construction upon Environmental Approval through: Design-Bid-Build Or Design-Build Public Hearing for Design-Build

14 Design-Bid-Build (D-B-B) DESIGN-BUILD VS DESIGN-BID-BUILD Project delivery in which NHDOT completes final design, obtains environmental clearance, acquires ROW & Utility relocations, prepares Contact Plans and Contract Specifications for construction NHDOT solicits for Design team for design and preparation of contract documents NHDOT acquires necessary Right-of-Way (ROW), clears utility relocations and develops project construction sequencing for advertising NHDOT seeks bids from qualified construction contractors for the lowest bid price. NHDOT provides Quality Control and Quality Assurance throughout project

15 Design-Build (D-B) DESIGN-BUILD VS DESIGN-BID-BUILD Project delivery in which one qualified entity consisting of contractor and designer works under single contract with NHDOT to provide final design and construction services through a unified flow of work for implementation of the technical base concept as approved through NEPA. Design-Build selection based upon RFQ and RFP solicitation with scoring of technical proposal through best value. Design-Build team provides Quality Control with NHDOT administering independent Quality Assurance oversight for design, Right-of-Way acquisition and construction. NHDOT provides sequential approval for construction project(s) based upon earlier project clearance for design, ROW clearance and contract provisions.

17 DESIGN-BUILD BENEFITS The Design-Build Advantage: Faster Delivery collaborative project management means work is completed faster with fewer problems. Cost Certainty an integrated team is geared toward efficiency and innovation. Quality design-builders meet performance needs, not minimum design requirements, often developing innovations to deliver a better project than initially imagined. Singular Responsibility one entity is held accountable for cost, schedule and performance. Decreased Administrative Burden owners can focus on the project rather than managing disparate contracts. Reduced Risk the Design-Build team assumes additional risk.
