Design Of A Two-Story Primary School Building

Abstract

The project book shows development of entire design, analysis and cost estimation of the proposed two-storied reinforced concrete (RCC) primary school building that is going to be constructed in a rural community in Bangladesh. The aim was to design a safe, economical, and sustainable educational building that can comply with Bangladesh National Building Code (BNBC 2020) and up-to-date engineering standards. Architecture planning, structural analysis and environmental concern were incorporated in the designing process to promote functionality, safety and efficiency. The structural design and analysis of important members such as beam, column, slabs and footings were done using the ETABS software to ensure that the structural members would be strong and serviceable in all the load combinations. The architectural and structural drawings were prepared using AutoCAD and Revit which gave a vivid picture of spatial insight and visualization of the proposed school building. The Bill of Quantities (BOQ) and cost estimation was done on Microsoft excel based on the local construction rates and the standard rates of the Public Works Department (PWD). The entire estimated project price is about 8.12 million BDT which includes all the major construction elements. As well, special plans were worked out on the septic tank and overhead water tank, which were planned according to the BNBC and Public Health Engineering Department (DPHE) standards to guarantee hygiene and water security to the 420 envisaged users. To plan and monitor the construction schedule with the time-sensitive completion of every phase, a Gantt chart is also included in the project. The incorporation of environmental and community health infrastructure e.g. wastewater treatment and water storage systems contributes to school environment sustainability. On the whole, this work is an integration of theoretical and practical work, which illustrates the process of work on modern civil engineering projects, starting with conceptual design and ending with technical, as well as cost calculation. The paper emphasizes the role of the engineering software, standard codes, and sustainable design in enhancing the creation of sustainable and cheap educational infrastructure in rural Bangladesh. The result can be used as a guideline to future academic research and practical rural infrastructure development programs.
