N/A
Step-by-step solution
1. Review the given question regarding the degree of accuracy required for measuring dimensions in a detailed estimate. 2. Recall that in detailed estimation, dimensions are measured to the nearest 0.01 m (1 cm). 3. Compare with the given options and select Option (a) as the correct choice.
Explanation
In detailed estimation, dimensions are measured to the nearest 0.01 m (1 cm) to maintain high accuracy without making site measurements and calculations overly complex.
Shortcut
To remember measurement precision in Detailed Estimation, use the "Rule of 0.01": - Dimensions are measured to the nearest 0.01 m (1 cm). - Area is measured to the nearest 0.01 sq m. - Volume is measured to the nearest 0.01 cu m.
Common mistake
A common mistake is selecting option C (0.001 m / 1 mm) by confusing standard civil engineering estimation precision with high-precision manufacturing or mechanical tolerances, which is overly detailed for earthwork and masonry. Another frequent mistake is selecting option B (0.1 m / 10 cm) by assuming site measurements are rounded off to larger decimal values for simplicity. In standard practice, dimensions are measured to the nearest 0.01 m (1 cm).
Correct answer: A) 0.01 m
