Flowline theory asserts that subcontractors can work at optimum productivity rates with optimum safety and craftsmanship if their location is free of unnecessary materials and other crews. (Lean Construction practices also espouse a clear work area for maximum efficiency.)
When subcontrators understand that their work will not be interrupted with stops and starts on the jobsite, they can utilize the correct resources, manpower, and equipment. This efficient cycle keeps productivity rates predictable so superintendents can use look-ahead schedules to fix any conflicts before they happen.
Flowline theory is an integral part of Vico Schedule Planner, our construction scheduling software. By mapping crews by location with the quantities derived from the BIM, it has been proven to aid schedule compression by 10% without adding risk to the project.
