ConsensusDocs Publishes First Industry Standard Contract Integrating Lean Practices for Design-Build Projects

Jun 25, 2020

ConsensusDocs webConsensusDocs has published the Design-Build Lean Addendum, the first and only standard contract document tailored to incorporate Lean practices to specifically work in the design-build project delivery method.

Lean practices are growing in importance to the Architectural, Engineering and Construction (AEC) industry, because they improve value, efficiency and relationships. Design-build — an alternative project delivery method that has grown in popularity — offers integrated design and construction services. Until now, design-build projects have not explicitly incorporated lean practices contractually.

The ConsensusDocs 431 will help subscribers obtain the vast majority of the benefits offered by Lean tools and processes without requiring an integrated project delivery (IPD) contract. The Lean Design-Build Addendum coordinates  with the ConsensusDocs 400 series of design-build agreements but can also be easily be customized with other standard design-build agreements as well as customized design-build agreements.

SMACNA members receive a special discount on the ConsensusDocs 431 Design-Build Addendum.
