Units of Measurement MCQ with answer and solution

Concept

Units of Measurement in Estimation and Quantity Surveying

Formula

N/A

Step-by-step solution

1. Review standard units of measurement in estimation and costing. 2. Recall that thin surface works are measured in square meters (m²), while structural works like RCC beams and columns are measured in cubic meters (m³). 3. Compare with the given options and select Option (c) as the correct choice.

Explanation

Reinforced Cement Concrete (RCC) work for structural elements like beams and columns involves significant thickness and volume, so it is measured in cubic meters (m3) rather than surface area in square meters (m2). Plastering, damp proof courses, and whitewashing are thin surface treatments measured in square meters.

Shortcut

To easily remember standard measurement units in estimation: - Surface / Thin Works = Square Meters (m²): Works with thin or specified thickness like plastering, pointing, DPC, and whitewashing. - Structural / Volume Works = Cubic Meters (m³): 3D bulk structural elements like RCC or PCC for beams, columns, slabs, and footings.

Common mistake

A common mistake is selecting option B by incorrectly assuming that Damp Proof Course (DPC) is measured in cubic meters because it involves concrete or mortar. In reality, DPC has a specified standard thickness and is measured in square meters. Another mistake is choosing option A or D by confusing surface finishing works with volumetric structural works like RCC beams and columns, which are always measured in cubic meters.
