David MacKay

Lean Construction Planner & Consultant

For over 30 years I have been passionate about how to make the process better. That's what led me to Lean. Since starting Milestone Lean Consulting in 2019 I work with teams and organizations across the United States and do some training internationally. I have helped several organizations to make the Last Planner System® the way they plan and execute projects. In 2023 I was a major contributor to AGC's updated Lean Construction Education Program 2.0.

Before starting Milestone Lean Consulting, I was Learning & Production Manager for PCL Construction’s California Buildings district. I helped define and develop PCL’s Lean strategy, tools, and training including Lean Foundations, Last Planner System, 5S training, Value Stream Mapping, Lean Project Guide and Study Action Teams. I assisted several other districts in North America implementing Lean thinking and tools. While at PCL I did extensive training, facilitation and coaching both in the field and the office.

In my 16 years at PCL I was part of many project teams in the field as a project scheduler and then district Scheduling Manager. I learned about the Last Planner System® and made it the standard for scheduling in our district. Over the years I have trained hundreds in planning and scheduling and the Last Planner System, one-on-one in the field and in classroom settings.  

Since 1990, I have had the opportunity work work on a wide variety of projects with organizations from small to very large. I started in the industry with a large power plant design and construction firm where I managed the document control department and started scheduling. My next company designed, manufactured and constructed process and material handling systems. I was responsible for scheduling and expediting from proposal through construction. Later, I was the Project Controls Manager with a local general contractor before coming to PCL.

I love to learn and share what I have learned with others. We all have a sense that this industry can be a lot better. Lean thinking is how to get there. I hope we can work together soon.
