IntelliBid User Tip: Controlling Labor Loss in Overtime

Consider the following scenario: You have a small electrical job requiring twenty hours to complete, you have one day to do the job, and you have two electricians available to do the work on that day. Based on a typical 8-hour day, you’re going to need to schedule those two individuals for overtime however, Overtime comes with its own set of issues. Industry studies show that workers tend to slow down after eight hours due to fatigue, causing a slowdown on the job. Because of fatigue, your twenty-hour job is going to take a bit longer than estimated. Fortunately, IntelliBid has the tools to help you account for these types of situations.

Open an IntelliBid job. Set your Item Library to FEEDERS. Select the FEEDER ASMY BY AMPS-CU Catalog, then the 200 AMP CU FEEDER under the On-B-Joist Header, then the 200A CU EMT B-JOIST 3P4W+G. Select your connectors and couplings, Takeoff the FEEDER and enter these quantities:

  1. Pipe Length = 170′
  2. # 90 ELLS = 3
  3. # FIELD BENDS = 2
  4. ADD FT EA WIRE = 10′
  5. # SEGMENTS = 2 +G

This will give you about twenty-two hours of labor we need for our example.

Now go to Bid Recap and create a new bid with either the STANDARD or SHORT Bid Template. Go to the Direct Labor tab and make sure you have a total crew size of 2 under Straight Time, and the same for Overtime.

Now go to Bid Recap and create a new bid with either the STANDARD or SHORT Bid Template

Follow these steps for the calculation:

  1. Go to the Labor Adjust tab and double-click in the cell in column B next to the label LOSS LBR CALCULATOR
  2. Select today’s date for both the start date and finish date, then click the Calculate button
  3. Notice that instead of the 4 hours overtime you originally estimated, the calculator shows 6.06 (approx.) hours,
    including 3.36 (approx.) hours of Productivity Loss.

Go to the Labor Adjust tab and double-click in the cell in column B next to the label LOSS LBR CALCULATOR

Click Yes to accept the adjustment, then click OK. You will find that IntelliBid has reduced your Straight Time
hours to 16, also applied the 6.06 hours to Overtime and adjusted Productivity Loss Hours to 3.36.
Your Total Adjusted labor is now 22.06 hours.

Click Yes to accept the adjustment, then click OK

The Bottom Line

As estimators, you are looking at the raw numbers of hours based upon the material required to run this job from within your estimate, but that doesn’t tell you the true cost of what is going on with the time and your crew mix.  You can see from the Labor Loss Calculator not only that additional time may be required to complete this job with a 2 man crew, but the hours to install the material provided on the takeoff page of the estimate (and based on a 2 man crew) shows only 4 overtime hours versus the actual of  6.25 hours. Had you stayed with 20 hours, you would have lost the additional hours really needed to do the work based on the impact that fatigue had on the crew.
