Making improvements to field productivity requires a deep understanding of the entire value stream and the tools to effectively streamline it.

Field Productivity: Lean Principle, Value Add vs. Non Value Add

This starts with mapping out every step in the process then identifying those steps that are truly adding value to the customer:

  1. The customer must be willing to pay for it.

    2. It must transform the raw materials (inputs) in some way.

      3. It must be done correctly the first time. 

When you look at each step through this lens you start to see a lot of activities that don’t add value (Non Value Add).  These get broken down into two categories:

  1. REQUIRED: Inspections, Submittals, Etc.

    2. PURE WASTE: Additional Handling, Waiting, Etc.

Our approach is “High-Involvement Workflow Mapping” which forces teams to slow down enough to truly see what they are doing, communicate with each other and identify then eliminate waste with each cycle (PDCA).

The Average Field Day in Detail (Craft Labor + Foreman)
Labor is often the biggest cost variable on a construction project. Just over half the field hours are related to actual installation. Understanding how time is spent on average in the field is the first step to improving field productivity.
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.
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%.
