Chapter 3, Problem 1RQ
What is the objective of a quantity takeoff?
Expert Solution & Answer
To determine
The objective of quantity takeoff.
Explanation of Solution
The target of a quantity takeoff is to separate everything into quantifiable and concise advances dependent on the bid drawings and specifications. By separating the work along these lines, estimators can dole out material, labour, and equipment expenses to each progression, and eventually build up an all-out expense for the task. The smaller and increasingly careful the estimations, the more exact the final quote will be.
