According to IS 1200 Part 4 (1976), stone masonry quantities are measured primarily in cubic metres (m³), while visible face work is recorded in square metres (m²). Although the code does not explicitly prescribe decimal precision, standard practice involves measuring areas to two decimal places and volumes to three decimal places to ensure accuracy for estimation and billing purposes.
Per IS 1200 Part 4 Clause 4.4, pillars and columns are classified into rectangular or polygonal shapes on plan, curved shapes with any radius, and other miscellaneous types. All are measured by volume (cubic metres). Rectangular pillars are defined by a breadth not exceeding three times the thickness and a maximum thickness of 60 cm. Accurate description and volume calculation based on dimensions or radius for curved types are required.
IS 1200 Part 4 mandates specifying the stone type, walling kind, and mortar mix in the description. General stone walling includes bond stones, joint raking, rough cuttings, holes for services, and embedded fixtures measured together. Facing stones differing from the body are measured separately by area with details on facing type, bed thickness, and bonders. Underpinning stone walling is quantified separately, and wedging slabs atop underpinning are measured in square metres.
As outlined in IS 1200 Part 4 (1976), flues with sectional areas up to 0.20 m² are measured as solid masonry without deductions. For flues exceeding this area, the flue volume is deducted from masonry volume, and pargetting or coring is measured separately in running metres with flue dimensions stated. Fireplace openings are not deducted, nor is extra measurement applied for splayed jambs or throating. This ensures fair and consistent quantification.
Yes, IS 1200 Part 4 Clause 2.7 requires stone masonry work done underwater, in liquid mud, under foul conditions, or affected by tides and snow to be measured separately. Although no special formulas are prescribed, these quantities must be recorded independently from regular masonry to account for additional complexities, risks, and contractual implications, ensuring equitable valuation.
