What is Lean Construction?
Lean Construction is a business strategy, a way of running your organization, and a set of tools and techniques that can continuously improve:
- Safety, Quality, Productivity, and Project Delivery
- Project Lead Times and Costs
Lean Construction is a “system” that is designed to maximize owner/customer value through the elimination of anything that does not add value—waste. This system is implemented through the training, empowerment, and participation of the entire workforce.
The goal of Lean Construction is to improve and grow the business by being competitive in supplying value to the owner/customer through the elimination of waste.

Lean Construction Training
WCM Associates LLC offers a Certified Lean Facilitator training program for Construction. The program includes an in-depth understanding of the “standard” Lean Tool Box along with the Lean Construction Gang Box, which covers the tools used principally in construction environments. The goal of this program is to allow Construction organizations to develop in-house Lean Construction experts so they do not have to rely on consultants for the long term. For companies to implement and integrate Lean as a system in their organization, they must “own” Lean.
