IS 1200 Part 28 establishes the standardized method of measurement for sound insulation works in buildings, including acoustic boards, quilts, and sealants. Quantity surveyors, estimators, and engineers use this code to accurately quantify materials for Bill of Quantities (BOQ) preparation, cost estimation, and contractor billing.

mouldings and skirting measurement unitRunning meters (m)
Practical Notes
A common mistake is measuring door frames (chowkhats) in square meters or running meters; IS 1200 requires them to be measured in cubic meters (m³).
Shutters for doors and windows must be measured in square meters (m²) separately from their frames.
Hardware and fittings (like hinges, tower bolts, handles) are usually enumerated (measured in numbers) and billed separately unless the item description explicitly states they are included.
Unlike standard linear measurements taken to the nearest 10 mm (0.01 m), the thickness of timber boards and scantlings is measured to the nearest 2 mm.
