Maintaining a high-level of jobsite productivity is one of the most important activities for any foreman, superintendent, or project manager. The first step to increasing—and maintaining—jobsite productivity levels is to understand what all the fuss is about.
When production rates drop, a project can lose money. Without proper documentation, these losses cannot be recovered. Worse yet, if production rates are left at a lower level, and a company adjusts their estimating to match their production rates, the company will become uncompetitive in the marketplace.
On the other side of the coin, if production rates are monitored closely, and improved upon constantly, then the company will gain a competitive advantage in the market, and any impacts will be seen immediately, when they can be dealt with. Many factors affecting productivity are well within our control, but many more factors are generally out of our control.
Here, we’re going to explore what productivity is and how it is measured.
What is Productivity?
Quite simply, productivity is a measure of how much of something is produced for a given amount of resources.
Productivity is related to job costing, but is typically more detailed in that it captures both the quantity of installation AND costs for a specific period of time.
Job costing systems typically capture costs at such a “big picture” level that it is impossible to get accurate production numbers out of them.
Job costing systems also typically run a minimum of one week behind, so by the time you could get any useful productivity information out of them—it is likely too late.
How Productivity is Measured
Productivity is expressed as a ratio between units produced or installed and
resources used.

A very simple calculation example is a trenching operation where production could be expressed in feet per day. Typically one of the numbers, either resources or units, is set to “1,” and that is typically expressed as the second part of the equation, as in the different examples below:
• 310 Feet Per Day
• $4.62 Per Foot
• 32 Fixtures Per Day
• 0.25 Hours Per Fixture
• $12.76 Per Fixture
The following table shows some typical Units and Resources used in productivity measurements:

Production Rates at Extreme Detail
A great example of production rates are the labor units used in the bidding of construction projects. These rates have been determined through very detailed cost accounting on a variety of construction projects.
There are several companies that assemble this type of cost data. Some are industry specific such as NECA (www.necanet.org), while others hit the broad construction market such as RS Means (www.rsmeans.com).
While this level of detail is required for accurate bidding, it is impractical to track job costs or production in the field at this level of detail.
Measuring Production in the Real World
You have to find a balance between labor units used for estimating, which are too detailed, and the job costing system, which is too broad and provides information that is too late.
A realistic production measurement timeframe needs to happen on a daily basis, at a maximum, in order to provide actionable feedback. These should also be summarized by the week to even out high-production and low-production days, as well as taking into account when setup and pre-fabrication is done to support higher production over the following days.
Production Rates are Relative
What is good production?
Production rates are relative. They mean nothing if they are not compared to something else.

The typical comparisons are:
• Estimated: If your production rate exceeds the rates you estimated the project by, you are making money. If not, then you are losing money. It is critical to know this on a daily basis so you can make corrections. If you are unable to attain the estimated productivity rates, then the feedback needs to get back to the estimators so they can adjust the production rates they estimate jobs at. Overestimating productivity on a bid CANNOT be made up for with more volume!
• Past Production: Comparing your current production rates to your past production rates on the same or other projects is the best way to determine if you are being impacted or if the new installation method is working.
• Industry Standards: This information is hard to attain, but with a little work, you can gain a lot of information and set benchmarks for your production. The importance of comparing your production with the rest of the industry is that if you can exceed that production, you will gain a competitive advantage, which equals more work, more profits, and more opportunity for everyone. The opposite is also true.
One other area you can compare production rates is between crews and even crew members. This will clearly show the wide variation between a top producer, an average producer, and a bottom producer. You can use this information to help share ideas about production, and in turn, raise the overall average. Having this data widely available takes care of a lot of people management problems because it makes it obvious where people really rank.
By understanding what productivity is, how it is measured, and by monitoring production rates closely, a company can increase their jobsite productivity level, and therefore, create a strong competitive advantage in the marketplace. It’s worth the effort!
