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.

Field Productivity - The Improvement Pyramid
An improvement of a few minutes per day to actual installation time compounded monthly is worth about $800K per year for a $25M contractor. What is it worth to you? Improvements to field productivity can be viewed as 4 major stages of a pyramid.
Impacted Productivity - Highly variable Labor Scheduling (Level Your Schedule)
The biggest risk for a specialty contractor is the performance of on-site labor. One of the biggest impacts to labor productivity is having a schedule that requires large variations in labor.
Changes - Impacts Beyond the Direct Costs
Contractors don't typically see the full negative impact of changes and, therefore, don’t put the right level of resources into their management.
