My estimating software had labor units set up in it for the time to install electrical items such as conduit fittigs, boxes etc.
It has 3 different labor times for each item. The 3rd labor column is NECA labor units. I would estimate a job and the software breaks the labor down by catagories such as conduit & racways, boxes, wire etc.
When doing the job I would track how much time was spent on each catagory and compare the actual time to the estimate time.
I would then make adjustments to the labor units in the software so the next time I estimated a job it would be more accurate.
You can purchase Means Electrical Cost Data book. www.rsmeans.com
It has labor units in it for installing electrical items. You can start out using the labor units in the book, track your actual time and adjust your labor units up or down if necessary. Write your labor units down in a book so the next time you estimate you can look up your labor units.
If you have estimating software its much easier to adjust and keep track of your labor units.
I'm using Vision Infosoft software for estimating large jobs.
Small jobs & service work I use Flat Rate Plus. http://visioninfosoft.com/ http://flatratesystems.com/
