2|Page Methods of Measurements and Units of Civil Construction Works The methods and units of measurements for civil construction works are mainly categorised for their nature, shape and size and for making payments to the contractor. The principle of units of measurements normally consists the following: a) Single units work like doors, windows, trusses etc., are expressed in numbers. b) Works consists linear measurements involve length like cornice, fencing, hand rail, bands of specified width etc., are expressed in running metres (RM) c) Works consists areal surface measurements involve area like plastering, white washing, partitions of specified thickness etc., and are expressed in square meters (m2) d) Works consists cubical contents which involve volume like earth work, cement concrete, Masonry etc are expressed in Cubic metres. Table below shows units of measurement of various items of civil engineering works based on IS 1200. Sl. No. Particulars of item Units of measurement Units of payment 1 Earthwork 1. Earthwork in excavation CUM Per CUM 2. Earthwork in filling in foundation trenches CUM Per CUM SAQIB IMRAN 2
