Wickwire Gavin, P.C. Minnesota Department of Transportation November 29, 2000 Michael C. Loulakis, Esq. Design-Build: Understanding the Basics
2
Wickwire Gavin, P.C. Presentation Overview l What makes design-build different? l How are design-builders selected? l How are design-builders organized? l What are the key design-build contract and risk issues?
3
Wickwire Gavin, P.C. What Makes Design-Build Different? l Approach is structurally different from other delivery systems l Single point of responsibility l Procurement options l Performance specifications l Role of design professional
4
Wickwire Gavin, P.C. Design-Bid-Build
5
Wickwire Gavin, P.C. System Strengths l Lowest initial construction cost l Full design developed before money spent on construction l A/E hired by Owner directly to act in Owners best interest l Owner can be actively involved in design process l Completed plans and specifications as benchmark for performance l Predictable rights & responsibilities
6
Wickwire Gavin, P.C. System Weaknesses l Linear nature of process l Actual construction cost determined after design completed – little chance to influence design without project delay – no contractor involvement in design or conceptual pricing
7
Wickwire Gavin, P.C. Cost Influence Curve
8
Wickwire Gavin, P.C. System Weaknesses (contd) l Challenges in obtaining high quality product l Owner warrants sufficiency of plans & specifications to Contractor l High potential for adversarial relationships l Unrealistic Owner expectations
9
Wickwire Gavin, P.C. Standard of Care Not Exact Science: Moundsview v. Walijarvi Architects, doctors, engineers, attorneys and others deal in somewhat inexact sciences and are continually called upon to exercise their skilled judgment in order to anticipate and provide for random factors which are incapable of precise measurement. The indeterminate nature of these factors makes it impossible for professional service people to gauge them with complete accuracy in every instance * * * an architect cannot be certain that a structural design will interact with natural forces as anticipated * * * The law has traditionally required, not perfect results, but rather the exercise of that skill and judgment which can reasonably be expected from similarly situated professionals.

Wickwire Gavin, P.C. Design-Build Plus
12
Wickwire Gavin, P.C. System Strengths l Single point of responsibility l Facilitates project financing l Shorter time to develop project l Total cost can be determined very early
13
Wickwire Gavin, P.C. Team Integration: Scheduling Construction team brought on after design, with open bidding: Prog Dev Prelim Drwgs Final Drawings Bid Construction Award Construction team brought on early, facilitating fast- tracking: Prog Dev Prelim Drwgs Final Drawings Procurement & Construction Cost Established
14
Wickwire Gavin, P.C. System Strengths l Single point of responsibility l Facilitates project financing l Shorter time to develop project l Total cost can be determined very early
15
Wickwire Gavin, P.C. System Strengths (contd) l Design innovation more readily achieved l High level of accountability can result in higher quality l Potential construction cost savings l Reduced conflict

17
Wickwire Gavin, P.C. System Weaknesses l Time & cost of implementing competitive process l Overly involved Owner may impact Design-Builder l Price provided before design documents completed l A/E doesnt work directly for Owner
18
Wickwire Gavin, P.C. System Weaknesses (contd) l Constraints with public procurement laws l Antiquity of licensing laws l Unrealistic Owner expectations l Lack of substantial judicial precedent
19
Wickwire Gavin, P.C. How Are Design-Builders Selected? l Direct design-build l Competitive negotiation l Best value proposals l Low price proposals
20
Wickwire Gavin, P.C. Negotiated Design-Build Procurement l Short-list l Interviews l Selection based upon: – teams experience – financial capability – key people – current & projected workloads – similar projects – pricing: fee & general conditions
21
Wickwire Gavin, P.C. Competitive Design-Build Procurement l Short-list l Selection based upon: – weighted criteria – adjusted low-bid – equivalent design/low-bid – fixed budget/best design – meets criteria/low-bid
22
Wickwire Gavin, P.C. Weighted Criteria Example * award to proposer with highest total score
23
Wickwire Gavin, P.C. Adjusted Low-Bid Example Note: The adjustment of the bid is for selection only. The firms price proposal is the actual contract amount.
24
Wickwire Gavin, P.C. Procurement Challenges l Remembering the design-build difference l Using consultants l Bridging/detailed design l Establishing qualitative criteria l Objectively analyzing criteria
25
Wickwire Gavin, P.C. Procurement Challenges (contd) l Stipends l Using information of unsuccessful proposers l Keeping A/E involved throughout project l Integrating procurement laws into solicitation
26
Wickwire Gavin, P.C. Balancing the Structural Framework of the Project l Project delivery systems l Procurement methodology – Negotiated – Competitive l Contracting approaches – Lump sum – Cost plus (GMP) – Unit Price
27
Wickwire Gavin, P.C. How Are Design-Builders Organized? l Integrated Design-Build Firm l Contractor as lead l A/E as lead l Joint Venture l Developer as lead
28
Wickwire Gavin, P.C. What Organizational Structure Works Best? l Owners needs & comfort level are key drivers l Nature of project l Licensing requirements l Relationship among team members
