Jacobs Mechanical has worked with Messer Construction Co. on two projects where a Flow Construction schedule

was implemented, and in our opinion it worked very well. Knowing on day one of construction which area we were going to be in, and the amount of manpower we would have on site at any time throughout the project, was very helpful from a management point of view. This allowed us to be more productive and Lean."
