Downloadable WORD Document — DBIA Document No. 530 (“Agreement”) should be used when the parties intend that Owner pay Design-Builder the Cost of the Work plus a Fee, with or without a Guaranteed Maximum Price (“GMP”).

If there is uncertainty about Owner’s Project Criteria, or the Project Criteria remain to be developed by Owner and Design-Builder together, a cost-plus/GMP contracting approach is desirable.

If there is certainty as to Owner’s Project Criteria, a lump sum fixed price for the completion of all design and construction services may be suitable, especially when the Owner procures Design-Builder’s services by competitive means. In such case, DBIA Document No. 525 should be used.
