Design Of A Two-Story Primary School Building In Savar, Dhaka

Abstract

The primary focus of this capstone project is the structural design of a two-story primary school building, total students 400 numbers, whose floor space measures about 6166 square feet (124 feet by 64 feet) and a general height of 24 feet. The building has nine classrooms, a library, a head office as well a teacher room. Structural analysis was done in ETABS 2020 as per Bangladesh National Building Code (BNBC 2020). Examples of reinforced concrete components are beams, columns, slabs, combined and isolated footings which were designed with regard to strength, serviceability and safety. As an example, 12" × 12" columns were supported using 4 bars 6 c/c, and 15 × 24" were supported using 4 bars 6 c/c. The project has four types of beams & also were employed, respectively have two types of footing, The detailed drawings were made in AutoCAD and the Bill of Quantities (BOQ) was managed and calculations related to design (septic tanks and stairs) were made in Excel. The estimated project construction cost was BDT 10,186,757 approximate. The structural system used was the Intermediate Moment Resisting Frame (IMRF) and the calculated weight that was going to be live in classrooms was 3kN/m2.The septic tank is composed of a total of 62.43 m3 and maximum capacity of 400 users, that is designed to receive 30 liters of effluent per capita daily. Environmentally sustainable technologies, paving that is pervious, meeting of ventilation and lighting standards all helped in environmental sustainability. The project makes us ready to face real world challenges of civil engineering by closing the gap that exists between theory and practice.
