121 Module 7: Resources & Estimating Process

With the work breakdown structure and dynamic schedule in place, you begin to estimate the hours of work for each task and assign crews/subs to do that work. This adds flesh to the skeleton of your schedule and gives you a first draft of how long the project will take and its completion date. If at all possible, you want to involve your crew in making estimates because when you do, you get better and more accurate estimates.

You will enter the work estimates into the software along with the availability of each crew member or sub. Some people are available half-time, other people can work full-time on the project. Whichever is the case, you enter that data so the software can calculate how long each task, and the entire project, will take to finish.

What Happens If I Don’t Do Estimating and Assigning Resources to Tasks Correctly?

Unfortunately, many construction project managers don’t follow the best practices in estimating and assigning resources. Instead they back into the finish date for each task based on the completion date the customer/owner has given them for the whole project. This is like plucking due dates out of the sky with absolutely no basis in fact. If you don’t have good work estimates and don’t consider the availability of your crews and subs, you are kidding yourself about the completion dates of the tasks and the entire project.
