Design of a Two-Storey Primary School Building (Zone 3)

Abstract

The structural design of a two-story primary school building, with a floor space of around 7038 square feet (153 feet by 46 feet) and a total height of 24 feet, is the main emphasis of this capstone project. Nine classrooms, a library, a head office, and a teacher's room are all part of the building. ETABS 2020 was used for structural analysis in accordance with the Bangladesh National Building Code (BNBC 2020). Beams, columns, slabs, and isolated footings are examples of reinforced concrete components that were made with strength, serviceability, and safety in mind. For example, #6 bars (20mm dia) were used to support 12" × 14" columns, and footings like F-41, which were 96" × 72" and 18" deep, were used. AutoCAD were used to create detailed drawings, while Excel was used to handle the Bill of Quantities (BOQ) and design calculations (such as septic tanks and stairs). The project is projected to 122 days to complete, with a total estimated construction cost of BDT10,000,000. An Intermediate Moment Resisting Frame (IMRF) was the structural system employed, and the live load for classrooms was calculated to be 3 kN/m2. With a total volume of 99.3 m3 and a capacity of 320 users, the septic tank was built to handle 30 liters of effluent per person every day. Energy-efficient technologies, pervious pavements, and compliance with ventilation and lighting regulations all contributed to environmental sustainability. This project prepares us for real-world civil engineering difficulties by bridging the gap between academic understanding and actual implementation.
