The Cost Analysis of an Education Building through Computer-Aided Design according to Different Flooring Systems

Abstract

Computer-aided Design (CAD) means that an analysis can be made in an electronic environment. As in all the sectors, its usage has reached to further levels in the construction technologies. Beginning from the architectural project, all of the related project and calculations are provided through CAD programmes. While deciding upon which construction system is used in the construction at the stage of project, it is an important subject for construction firms that projects are prepared according to different construction systems and the most appropriate cost is obtained by making quantity survey. Through today’s CAD programmes, analyses were made on the same project according to different construction techniques at short notice and their quantity surveys were made in short durations and through which technique with the most appropriate cost, the construction is decided to be built. In this study, IdeCAD Structural ver 7.020 that is commonly used in Turkey as CAD programmes was used and a project of an education building was prepared in the system of framework and as normal flooring and also ribbed floor slab and separate Reinforced Concrete (RC) Static projects of the building were prepared according to the available regulations. Quantity survey of concrete, formwork, reinforcing bar belonging to both two projects and their cost analyses were made and compared. As a result of comparing, it is determined that normal flooring system can be constructed with a more affordable cost than ribbed floor slab system.
