ConsensusDocs has just released the first industry standard document tailored to incorporate Lean Practices to specifically work in the design-build project delivery method. Lean practices improve value, efficiency, and relationships in the design and construction industry. Design-build is an alternative project delivery method that has grown in popularity that offers integrated design and construction services, but industry forms have not explicitly incorporated lean practices contractually. Rather than rely upon cultural aspirations that can backslide, learn how you can leverage the just released ConsensusDocs 431 Design-Build Addendum to memorialize Lean practices in your next design-build project. This will allow you to get many of the benefits offered by Lean without requiring an integrated project delivery (IPD) contract. Getting your contracts right to encourage Lean is difficult. Now there is an industry contract standard form to help.

 Learning Objectives 

  • Gain an overview of the ConsensusDocs 431 Lean Design-Build Addendum and 305 Lean Construction Addendum
  • Learn Lean project fundamentals that you can incorporate in your project’s contracts
  • Understand how using an IPD contract like the ConsensusDocs 300 is not required to get many of the benefits of the Lean practices.

Tom Richert
Rising Terrain LLC

As a team productivity coach with a twenty-year history of working with lean design and construction practices Tom helps enterprise and project teams integrate workplace culture development within a lean management framework. His approach recognizes that personal satisfaction and professional growth thrive in an environment of shared leadership culture. Cultivating this culture is a necessary condition for teams to embrace lean practices enthusiastically.

Tom’s path to understanding the importance of culture began with management experience on teams applying sound, disciplined work practices. As Tom transitioned from leading to coaching teams, he observed that some teams were successful in embracing lean practices while other teams resisted making such changes. His continuing investigation into this dichotomy reveals that the source of human productivity lies with a personal commitment to a shared meaningful purpose. Today he focuses his coaching on workplace culture, resilience, and productivity for enterprise and project teams.

Tom lives outside Boston with his wife, and a teenage daughter with aspirations for a technical career in musical theater.
