Time-on-Tools and Minimum Required Installation

Labor productivity IS NOT the biggest problem with field productivity. Under similar conditions the variation in how fast two crafts people actually “turn wrenches” is about 2X but there are far bigger problems to tackle. Focus on these three areas.

Field Productivity: Labor Productivity IS NOT The Biggest Problem With Project Productivity

 

  1. Maximize Time-on-Tools (ToT): Ensure that crafts people spend most of their day working with their tools actually installing things.  Different studies place the industry average between 50-65%.  Leverage the 6 Pillars of Productivity and ABC Daily Planning.  
  2. Minimum Required Installation (MRI): Don’t take critical shortcuts but don’t over-build the project.  In the field we would call it “Gold Plating.” Effective installation details, craft training and good field supervision practices will ensure that you get the right level of quality. 
  3. Minimize Rework: The only greater waste than installing more than what is required is doing it twice.

General Contractors and Project Owners can do a lot to set the conditions for success with their labor-intensive subcontractors.

Lean Principle - Stop Work (Until Problems Are Corrected)
All construction projects will run into some degree of problems. It is how the project team chooses to manage these problems that ultimately determines the outcome of the project.

Impacted Productivity - Stacking of Trades and Installation Efficiency
Each craftsperson needs about 200 usable square feet for a productive installation. This assumption is included in production units used to estimate and budget projects. Having less than that can impact productivity up to 50%.
