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. The most ideal situation is to have a steady ramp up, stable crew size during peak production followed by a steady demobilization.

Field Productivity: Impacts - Unleveled Manpower Schedule.

 

No project will be perfect and impacts to highly variable labor requirements include:

  • Overloading the project to meet demands resulting in too many people during downtimes, which then lowers productivity.  
  • Learning curve for new team members coming on and off the project. Studies show that productivity can be impacted by as much as 10% during the first week for a craftsperson learning a new project. 
  • Overtime required to meet the schedule. Not only will you have the increased cost per hour, but you will experience a decrease in productivity and safety. Four weeks at 5-10’s will impact productivity by 20%.
  • Poor scheduling often goes hand-in-hand with stacking of trades which can cost another 10-50% decrease in productivity for those areas.  
  • There is an increase in the coordination time it takes to move manpower on and off the project which has a direct cost as well as an indirect cost from dilution of management.

Lean Principle - 8 Categories of Waste
The first step in improving labor productivity in construction is improving everyone’s ability to see the waste. Waste can then be broken down into 8 major categories. Like colors these are often interrelated.
Lean Principle - Value Stream
A contractor’s value stream is every step required to take raw materials and information then deliver a completed project to the waiting hands of a customer. Deep understanding of this value stream is the foundation for major productivity improvements.
