Having gotten a brief overview of Lean Construction, let’s look at an actual construction project that applied integrated Lean Six Sigma. Gaurav Chauhan, currently Executive Director for Dubai-based Unified Workspace, a Project Management company, takes us through the safety-related project.
The project was designed to determine a company’s current safety performance and develop a solution to improve it.
They followed the DMAIC structure with Lean tools incorporated. What follows is a detailed look at all elements of the DMAIC application, from Project Charter to validating implemented improvements.

Finally, let’s look at another example. In this paper titled “Implementation of Six Sigma Methodology in Construction Industry For Quality Process Improvement”, by Ar. Priya Swami, and Ar.Bhagyashree Kadiwal, Six Sigma is used to evaluate plastering defects in building projects in a case study of a residential complex of 100 flats.
