Nature of contract • Performance based design‐build

Setting the Stage

• Firm fixed price contract

Two‐part Contract • Firm fixed price contract

• An initial concept design phase to prove that theDB team could do what they said they could do—50% of fee at risk in this 6 month period

• Award of a FFP contract following acceptance ofthe conceptual design—remaining 50% of conceptdesign fee paiddesign fee paid

Performance Incentive Program

• Incentive for “supperior pperformance”

Architects dislike competitive design‐build • proposal costs extreme, risks are very high • undesirable relationship with GC • insulation from owner—difficult to understand their needsdifficult to understand their needsinsulation from owner • Program and requirements may not be clear

Keep end in mind • back end incentive • Once project awarded, DB team can execute effectively and

efficiently • incentivize designer’s up front investment with stipend • Performance incentive is a critical ingredient to make the risk

worthwhile

• Commitments made early have to stick later on. • Risk must be minimized by lack of change—decisions must bemade and adhered to throughout the detailed design processmade and adhered to throughout the detailed design process

• This requires more detailed performance analysis in everystep of design.
