Textbook Question
Chapter 5, Problem 1RQ
Why is it recommended that the estimator begin a takeoff of concrete work by measuring the quantity of concrete in an item rather than the amount of formwork?
Expert Solution & Answer
To determine
The reason recommended for the estimator to begin a takeoff of concrete work by measuring the quantity of concrete in an item rather than the formwork amount.
Explanation of Solution
Taking off concrete work must start with the estimator measuring the concrete as the actual concrete descriptions are usually given on the drawings, whereas the details of the formwork are not given. The estimator can then review the needs for the formwork by measuring and estimating the volume of concrete needed followed by the requirements of finishing.
Since only the area of forms in contact with the concrete is measured, at the time of the takeoff, the estimator does not have to review the descriptions of the forms design.
