Quantity Take-off - Learn Civil Engineering. In this chapter, we will explore the most common practices of taking off quantities for an electrical construction project and offer suggestions. Even material procurement and equipment rental terms will have their genesis in the takeoff. Make your workflow fast and easy for a polished final product. It should also be noted that if the bid is successful and the work is awarded, the estimate will serve as the basis for the performance measurement baseline for project control. Connect the power of pivot tables and Microsoft Excel when doing quantity takeoff tasks. For example, a schedule for performing the work can be created from the estimate, specifically crew composition, labor-hours, and task definition. The takeoff should be organized so that the information gathered can be used in other parts of the construction process. Errors or inaccuracies in this portion of the estimate are compounded during the pricing phase, regardless of how reliable the unit prices are. A precise and thorough quantity takeoff is the basis for a sound estimate. As a result, the electrical estimator must not only count the items shown on the drawings but also envision the completed work, including fittings, hangers, fasteners, devices, and cover plates. Much of the work is shown with symbols and graphics that illustrate the design. The amount of detail shown on electrical drawings is perhaps the least of any for the major trades. The takeoff is the decomposition of the work shown on the plans and specifications into units of measure that can be priced. (For entering the item total quantity as well as annotations).

It is essential to know all the quantities needed for a project before commencement. Even material procurement and equipment rental terms will have their genesis in the takeoff. Quantity takeoff is a simple concept that lists all the materials needed for construction. A more thorough process is necessary for major construction projects, however. For a small one-off job, an experienced builder should be able to estimate the materials required in his or her head. It should also be noted that if the bid is successful and the work is awarded, the estimate will serve as the basis for the performance measurement baseline for project control. This process is known as takeoff or material takeoff (MTO) and is an essential part of the estimating process.

However, implementation of model-based quantity takeoff in production must be done in several steps, the first step being to get production personnel working digitally with drawings using PDF viewers. For example, a schedule for performing the work can be created from the estimate, specifically crew composition, labor-hours, and task definition. Model-based quantity takeoff saves time, reduces waste, and gives opportunity to control invoices more frequently. The quantity survey or takeoff is the starting point for any estimate.
