For computing the quantity of plastering on walls, the area measured is:
Choose the correct answer
Only external face area
Net wall face area (length x height), with deductions for openings (doors, windows) above a threshold area, and additions for reveals, jambs, and soffits of openings
Gross area without any deduction
Floor area only
Correct Answer
B. Net wall face area (length x height), with deductions for openings (doors, windows) above a threshold area, and additions for reveals, jambs, and soffits of openings
Why is this the answer?
CPWD plastering measurement: length x height (net area) minus openings > 0.5 m2 (some codes: > 0.1 m2). Additions: reveal (width x height of wall at door/window opening), sill (width x depth), lintels (soffit). Mortar quantity = (volume of plaster coat) / (1 - bulking factor). Typical plaster thickness: 12-18 mm (2 coats).
