Quantity take-offs are a detailed measurement of materials and labor needed to complete a construction project. They are developed by an estimator during the pre-construction phase. This process includes breaking the project down into smaller and more manageable units that are easier to measure or estimate
How do you do quantity takeoff?
What is a Quantity Takeoff?
Also known as estimating takeoffs, construction takeoffs, or material takeoffs, this process is about understanding the needs of a construction job ahead. They provide detailed measurements of the materials and labour that you will need to complete a construction project.
They are also used in planning, such as in making room lists to get your areas under control. Quantity takeoffs are mostly based on the physical, material requirements of a project, but they also cover other aspects such as rooms.
Before you start construction, you need to do a quantity takeoff in the pre-construction planning phase. It needs to include material estimates as well as anything else that the project requires. To produce quantity takeoffs, estimators will use blueprints or models and make a list of the materials needed to achieve the end-result.
While this was traditionally done manually (requiring a lot of skill), the digitisation of quantity takeoffs has advanced the process and made it far more accurate. This has included things like BIM, which helps to achieve the most accurate estimation results through detailed systems and models, and automated calculations. Get to know more!
