Step-by-step solution
1. Methods of building estimation vary in accuracy depending on the parameters measured. 2. Estimates based on structural volume provide quick approximations for valuation. Answer: D
Explanation
A detailed estimate involves calculating the exact quantities of all individual items of work from working drawings and multiplying them by their respective unit rates. Unlike approximate methods like plinth area or cube rate estimates, it provides precise cost projections based on full technical specifications. Therefore, option D is the correct answer.
Why the other options are wrong
A) Supplementary estimates are prepared for additions or modifications to original works. B) Plinth area estimates are preliminary and approximate methods based on floor area.
Shortcut
Detailed estimate is always the most accurate method of estimation.
Common mistake
Confusing detailed estimates with preliminary or approximate methods like plinth area or cube rate estimates.
Correct answer: D) Detailed estimate
