The formula to calculate the volume of cement is as follows: Hence let us take the quantity of cement mortar as 1.54 m 3. Dry volume of total materials is equivalent to 1.54 times the volume of wet concrete. Let us consider the volume method for reinforced concrete construction. The quantity can preferable calculated by two methods, which are weight & volume method. Let us assume a standard quantity of 1m 3 Cement mortar and a mix proportion of 1:1.5:3 (1 part Cement, 1.5 parts Sand & 3 parts CA). Materials requires for reinforced concrete are cement, sand, coarse aggregate and steel. Whereas in the Sums column we simply multiply the previous elements (Multiplication factor x Dimension) to Dimension column is the one where all the dimensions like length, width & depth are (multiplier column) is for filling up the number of repetitions of the same Measurement required into a sheet called the TDS Sheet. In this step, the appropriate narrative ofĪ particular work is provided to explain and justify the work being done. Taking off is the process of analysing the drawing and its specifications to identify the elements required for the preparation of BOQ.
