Comprehensive Cost Analysis and Quantity Survey of a G+1 Residential Structure

This paper presents a comprehensive cost estimation, quantity survey, bill of quantities (BOQ), and bar bending schedule (BBS) for a G+1 residential building with a total built-up area of 1350 sq.ft (27' × 25' per floor). The study encompasses all phases of pre-construction planning including architectural drawing interpretation, structural component analysis, material take-off calculations, and reinforcement detailing. AutoCAD was used for preparing structural layouts while Microsoft Excel facilitated systematic computation of material quantities. The total estimated quantities include 34,150 bricks, 840 bags of cement (50 kg each), 2,480 cubic feet of sand, 2,050 cubic feet of coarse aggregate, and 6,120 kg of steel reinforcement bars. The Bill of Quantities was prepared referencing Schedule of Rates (SOR), Bhopal, arriving at a total project cost of approximately Rs. 26,40,000. This paper also includes a detailed bar bending schedule for all RCC components such as footings, columns, beams, and slabs. The findings highlight the significance of systematic pre-construction estimation in ensuring cost efficiency, optimal resource allocation, and timely project completion.
