Planning & EstimatingCâu 505 / 700
When performing a quantity takeoff from a set of plans, which practice BEST reduces costly estimating errors?
a.Rounding every dimension down to the nearest foot to save material
b.Estimating only from memory of similar past jobs
c.Counting only the most expensive materials and guessing the rest
d.Systematically measuring each assembly, cross-checking scale against noted dimensions, and applying consistent waste factors
Giải thích
Accurate takeoffs come from a systematic, checked process: measure each assembly, verify the drawing scale against the dimensions actually written on the plans, and apply consistent waste and coverage factors. Option d captures this. Rounding down (a) causes shortages, memory-only estimates (b) miss job-specific conditions, and guessing (c) produces unreliable bids.
