In construction projects, small mistake in takeoff can make very big problem later. Many time, when measurement is not correct or some item is missing, the budget go over and client not happy. I see this happen when team not pay attention for detail or they rush work too much.

One common error is wrong quantity of material. If you calculate less, project run out of material and more money spend. If you calculate too much, then cost is also high. Another mistake is not include labor cost proper, which always create issue in final budget.

For this reason, having good construction cost estimator is very important. Estimator can check takeoff careful, make sure numbers are right, and help team to avoid big overruns. Many company use software also, but still human checking is needed.

In my opinion, best way to reduce error is slow down a little, double check work, and let estimator review before final. It may take more time in beginning, but in the end it save project from losing money.
