…a delivery method in which the construction team is known as the design-builder…and is responsible for taking a concept developed by the owner, completing the detailed design, and proceeding into construction.

DB offers the following: ◦ Poses Least amount of Project Risk to Owners ◦ “Quickest” Project Delivery Method Early Construction concurrent with Design ◦ “Integrated” DB Team develops design with constructability in mind, which: Reduces Changes / Change Orders to Project Reduces need for Value-Engineering / Re-Bidding Improves quality of Final Design ◦ Can be used on any sized Project ◦ Use of Design Assist Contractors during design
4
Minimizes Owner Control over Process May be Difficult Method to Use on Complex Projects Building Over-Design may Increase DB Profits …Did the Owner get the Best Price for the final Product?
5
Criteria Architect (C-AE) – Defines Design Intent through Schematic Design, selected through co-selection process by owners Project Cost Consultant (PCC) - Third Party Entity that advises Owner related to Project Cost while in Design and assists in GMP Negotiation, selected by the co-owners Design Builder (DB) – Provides input in Design, Negotiates GMP, Bids Project and Oversees Construction ◦ Architect of Record, General Contractor ◦ Design Assist Contractors – usually MEP
6
Team consists of Criteria Architect (C-AE) and Design-Builder (DB): Design Begins (POR) Design Ends (GMP) Criteria Architect Design Intent Finalized (SD) Design Builder: Architect of Record General Contractor Design Assist Contractors Criteria Architect / Owner’s Representative
7
Design-Builder (DB) bids project and oversees construction, with the C-AE serving in an Owner’s Representative (OR) function: Construction Begins (GMP) Construction Ends Design Builder: Architect of Record General Contractor Subcontractors Criteria Architect / Owner’s Representative
8
Each District/Project is Unique in Some Fashion ◦ Construction Experience ◦ Knowledge of Program ◦ Community Involvement ◦ Decision Making ◦ Scope ◦ Complexity ◦ Schedule
9
Owner Familiar with Construction Programs & Processes Owner Availability of Staff (Moderate Level) ◦ Single Decision Maker Owner Risk Tolerance (Low Level) Owner Level of Control (Low Level) ◦ Original Design vs. Project Changes Level of Changes to Original Scope ◦ Original Schedule vs. Project Changes Level of Changes to Original Schedule
10
Medium to Large Projects (> $2 million) Simple to Moderate Complexity of Projects ◦ Design & Schedule Aggressive Schedule Expectations
12
Establish and Procure Project Funding Determine DB Delivery is best method Co-Selection of C-AE – RFQ Process Co-Selection of PCC – RFQ Process Co-Selection of DB Team – RFQ/BVS process, Includes: Selection of DB – RFQ/BVS process Two Step Selection Process Negotiation of GMP Occurs between SD & DD Phase Re-Confirmation of GMP to Design Intent Bidding Pre-Qualification of Potential Bidders by DB DB bids and awards Contracts, may perform work Construction & Closeout
13
Occurs between SD and DD Design Phases Small, Select Group from District & OSFC ◦ Cost Estimate from DB / Design Assist Contractors ◦ Cost Verification from Project Cost Consultant Conduct Facilitated Session for Negotiation Upon GMP Agreement, Design Intent is revisited
14
Experience ◦ Financial condition ◦ Performance on previous projects ◦ Facilities ◦ Management skills ◦ Ability to contract properly Goals ◦ EDGE etc. Affirmation of non-violations past (5) years Proof of licenses to perform work Self-Performance
