This take-off was prepared in accordance with the BESMM4 4th edition, During my industrual training programme. The sole purpose of the calculations are to serve as a guideline for fellow students. It includes some mechanical and electrical Full PDF Package Download Full PDF Package. This Paper. A short summary of this paper. 1 Full PDF The rebars (1) must have a length of 5.50 m instead of 5.52 m due to a minor difference (where the left upper horizontal part of the bent-up rebar becomes 0.72 m instead of 0.73 m and the right upper horizontal part becomes 0.181 m instead of 0.182 m). The rebars (2) will be formed with a length equal to 4.50 rather than 4.33. 13. 4 TAKING OFF QUANTITIES: The dimensions should always be recorded in the order of length, width and height. Column C is the squaring column where the result of the addition, subtraction or multiplication of the entries in the dimension column is recorded. Figures which are to be added or subtracted are bracketed together in the manner shown. Framing take-offs introduce at .035 per square foot under roof. Cornice and siding, millwork, and all additional estimating requirements are charged individually. For several elevation plans with options, add-in and back-out quantities are coordinated with the base plan to get the most out of material optimization. Step 1: Takeoff quantities- the work to be performed by a contractor is measured in compliance with standard rules of measurement. Step 2: Recap quantities- the quantities of work "taken off" are sorted and listed to comply with the CSI MasterFormat or other standard to facilitate the process of pricing. They are designed to make measurement of (taking-off) quantities an easy task. They are in Microsoft Excel format which most of us are familiar with. (1) General.

Concrete & Formwork for Pilecap/Footing (For viewing only) • Overlap standard distance is= 40*max Diameter for tension, 50*max Diameter for compression. • Cover distance = 0.005m in foundations only and 0.025m otherwise. • Stirrup key is 0.1 *2= 0.2m • Rebar order format is as follows: - Calculated Number Ø Standard Diameter/ Standard Length • Rebar volume is negligible in concrete quantity take-off. Calculation of materials for Reinforced Concrete Construction . Materials requires for reinforced concrete are cement, sand, coarse aggregate and steel.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). The quantity can preferable calculated by two methods, which are weight & volume method. Traditional taking off uses dimension paper which is made of a series of columns. The columns are: 1. The timesing column, which gives the factor of multiplication for the measurements in the dimension column . 2. The dimension column, where the measurements are set down as taken from the drawings . 3. The squaring column, where the calculated Building Quantities Explained Building Quantities Explained Authors: Ivor H. Seeley 0; Ivor H. Seeley.
