Which cost-estimating method is the most detailed and the least used in everyday appraisal work?
Correct Answer
D) The quantity survey method
Why this is correct: The quantity survey method is the most detailed cost-estimating approach. It involves listing and pricing every single component of construction (materials, labor, equipment) and is essentially a contractor's detailed takeoff. It is rarely used in everyday appraisal due to its time-intensive nature. Why the other choices are wrong: 'The comparative square-foot method' is the most common and least detailed. 'The unit-in-place method' is more detailed than square-foot but less than quantity survey. 'The index method applied to historic cost' is a trending method, not a detailed construction estimate. Exam tip: Know the hierarchy of detail: Quantity Survey (most detailed) > Unit-in-Place > Square-Foot > Index (least detailed).
