Quantity surveying (QS) calculators for Indian construction BOQ — RCC concrete, brick masonry, TMT steel weight, cement–sand mortar, and wall plaster. Free educational estimates for site engineers, contractors, and students.
Calculator cluster
Concrete Volume Calculator (RCC)
RCC slab, beam, column, footing — M10–M25, dry factor 1.54.
Brick Quantity Calculator
Wall brick count, mortar 1:4, cement & sand — IS 1077.
Cement–Sand Mortar Calculator
Mortar by volume or area × bed thickness, 1:3–1:6.
Plaster Quantity Calculator
Single/two-coat plaster, 6–20 mm, cement & sand f=1.33.
How these tools connect
RCC first: use the concrete volume calculator for slabs and columns. Masonry: brick quantity for walls, then mortar or plaster calculators for finishes. Steel: TMT weight from diameter and length — pair with concrete BOQ, not a substitute for a bar bending schedule. All mortar/plaster tools use dry factor 1.33; concrete uses 1.54.
