Impacted Productivity - Unleveled Manpower

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 sporadic manpower schedule.  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 manpower include:

  • Over-manning the project to meet demands resulting in too many people during downtimes lowering 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.  4 weeks at 5-10’s will impact productivity by 20%.
  • Often poor scheduling 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.
