Addendum to Agreements Between Owner and Construction Manager and Between Owner and Design Professional for Design-Assist Services

(Updated 2018) Purchase Options

The ConsensusDocs 541 Design-Assist Addendum creates a contractual structure to better coordinate design professionals, construction managers (CM), and trade contractors in the design development phase. This a first-of-its-kind standard construction contract, and provides a range of elected services that range from constructability analysis to value-engineering to life-cycle analysis. The design-assist addendum coordinates with the recently released ConsensusDocs 305 Lean Construction Addendum by allowing users to opt into several Lean construction tools and processes that begin in the design phase and carry-on throughout construction. The Lean and Design-Assist Addendums work well together or independently.
