While preparing estimates, the methods and rules that estimators follow depend on several factors, including training, experience, the type of project and company culture. In some instances, estimating practices may not mesh well with project management requirements. One of the most common discussions I have had with project managers is in regard to the level of detail in an estimate.

I have been fortunate during my career to hold the positions of estimator and project manager, both separately and at the same time. This experience has given me perspective from both sides. Unfortunately, things were not always as harmonious as they should have been. As an estimator, I had to deal with project managers. As a project manager, I had to deal with estimators. READ MORE

A friend recently asked me, “What’s so hard about bidding electrical work? You don’t even need a college degree to be an estimator.” I said he was oversimplifying things and told him it can be a complex, highly detailed process with many strategies and chess-like moves. He asked me to explain it to him, and I was stymied at first because I did not know where to begin. READ MORE
