The phrase "doing take off" refers to the process or action of estimating or calculating the quantity and cost of materials required for a construction project. Primarily used in the field of construction, particularly by cost estimators and quantity surveyors, doing take off involves carefully examining construction plans and blueprints to identify and quantify the various components and materials needed.
During a take off, the estimator goes through each component of the project, such as walls, floors, roofs, doors, windows, electrical wiring, plumbing fixtures, and finishes, to determine their quantities and associated costs. This meticulous calculation accounts for factors like dimensions, area, volume, and specifications provided in the plans. The aim is to create an accurate list, often referred to as a bill of quantities or a materials take off, which captures the quantities of all required materials.
Once the take off is complete, the estimator can determine the cost of the project by assigning unit prices to the materials based on current market rates. The estimated cost is crucial in determining the project budget, preparing bids, negotiating contracts, and assessing the feasibility of the project.
Accuracy and attention to detail are vital during the take off process as any errors or omissions can result in significant cost overruns or delays during construction. Therefore, professionals involved in doing take offs possess a keen eye for detail, technical knowledge in construction materials, and experience in interpreting plans and specifications.
