Lean and Integrated Project Delivery

Lean IPD combines lean management principles with a collaborative, aligned team and
contract structure to improve the outcomes of construction projects.

If Lean IPD fails, it is usually because of incorrect assumptions, poor planning, and the owner
not recognizing their own crucial role in leading the project.

Why is Lean Design and Construction
Important and What Does it Look Like
when Implemented.

Based on research from manufacturing and companies like Toyota, Lean focuses on Continuous Improvement and a Respect for People while looking to drive waste out of the value delivery system.

What is Lean IPD?

Lean IPD or Lean Integrated Project Delivery is a delivery model for complex construction projects focused on forming a single team of designers, builders, and owners
through aligned incentives, culture and contract structure.


Builders include the general contractor and key trade partners who have a significant impact on the outcome of the project.


Designers include the primary architect and key systems such as structural, mechanical, electrical and plumbing.



The owner is the entity who is sponsoring the project and ultimately responsible for

operating the completed project.  Involvement and leadership of the owner is

key to the success of IPD.

Together IPD and Lean are a powerful force – IPD providing the motivation and Lean the means for project success.  Lean IPD provides both the motivation and means to improve project outcomes.

Integrated Project Delivery (IPD) is a superior delivery model because it aligns the interests of the owners, designers, and builders at the outset of a project.  No more silos, no more hidden problems, no more posturing for claims, and no more disappointments at the end.  The IPD contract and the Lean Construction operating system that is mandated by IPD bring early engagement and full commitment of all parties to deliver the highest value at the lowest cost.  The side benefits are high levels of design innovation, safety, quality, and roughly 5X more likely to finish on time or ahead of schedule than traditional delivery.
