The ConsensusDocs 305 is an industry first document to facilitate lean tools without the need to sign a multi-party IPD agreement.
This quick overview will go over the new ConsensusDocs 305 Lean Addendum. The ConsensusDocs Coalition published the industry’s first Lean Addendum standard contract document in September of 2018.
The ConsensusDocs 305 utilizes lean tools and processes without an Integrated Project Delivery (IPD) agreement. Not all owners may procure design and construction services with an IPD or integrated lean project delivery (ILPD) agreement. The Lean Addendum provides a contractual mechanism for owners, architects, engineers, general contractors, and subcontractors alike to take advantage of lean construction efficiencies and memorialize in writing a more collaborative and cooperative culture on projects. Check out the ConsensusDocs Guidebook to the 305.
The Lean Addendum is significantly shorter than other integrated forms of agreement (IFOAs), such as the ConsensusDocs 300 standard IPD agreement. The ConsensusDocs 305 coordinates well the ConsensusDocs 500 CM At-Risk agreement and new ConsensusDoc 541 Design-Assist Addendum. Many would characterize the use of a CM At-Risk agreement with the Lean Addendum as an “IPD-lite,” “IPDish,” or “transitional” IPD agreement.
Joe Cleves, partner at Taft law firm in Cincinnati, who served as chair for the ConsensusDocs Coalition working group that developed the Lean Addendum, explained “this new standard addendum is perfect for all stakeholders involved in the design and construction process interested in incorporating lean processes on CM At-Risk projects.” He added, “publication of this document will benefit the industry in adopting lean tools, which have a demonstrated increase in construction productivity.”
