In the previous two articles in this series, I wrote about how to get information out of a database and into an estimate. So, let’s say you have entered all of your takeoff and have a file full of the selected electrical materials, each with its own price and labor unit attached. Now, you need a way to make adjustments and corrections to the estimate. READ MORE

The next function of electrical estimating software (after the database, which I covered last month), is having a way for you to enter your takeoff into the estimating system. How do we get items out of the database and into the estimate? That is the job of the user interface.

During the week of Nik Wallenda’s tightrope walk across the Grand Canyon, my wife mentioned the stunt several times, so we ended up watching it on TV on June 23, 2013.
