Quantity Take-off (QTO) and Estimating Trades

In this course, you’ll move from estimating fundamentals to applied practice, learning how estimators measure and interpret work across multiple construction trades. You’ll explore how takeoffs for site and earthwork, concrete, metal, masonry, and carpentry are performed and how each trade contributes to the overall project cost. Through detailed demonstrations and real-world examples, you’ll see how professional estimators use digital tools like On-Screen Takeoff (OST) and Bluebeam Revu to perform accurate, efficient quantity takeoffs. Even without direct software access, you’ll gain a clear understanding of how technology supports modern estimating workflows. Finally, you’ll connect quantity data to productivity and time, analyzing how labor rates, crew efficiency, and scheduling impact the total estimate. By the end of this course, you’ll be able to interpret trade drawings, understand digital takeoff processes, and evaluate how productivity influences cost—all essential skills as you advance toward presenting and defending a professional construction estimate.
