Modeling and cost analysis of exterior scaffolds using different materials

Construction industry; It is a business line that creates demand for the production of goods and services in more than one sub-sector of its own, plays a leading role due to its contribution to economic growth, and accordingly, its importance has increased over time. Our country is developing rapidly and the construction sector is at the center of this development. The first step of all infrastructure and superstructures, such as bridges, hospitals, residences, roads, dams, which will benefit the development of countries and determine the level of development, is taken with construction. Facade scaffoldings are widely used in this sector. Especially in the construction of works such as plaster, paint, insulation, facade scaffolds are used. Especially in recent years, increasing housing construction has led to an increase in the use of facade scaffolds. This increase has brought with it some negativities in terms of occupational health and safety. Occupational accidents caused by falling from a height are mostly due to the use of unsafe scaffolding. In this context; Work scaffolding should be evaluated according to the principles defined in the standards and occupational safety legislation. In addition, the effect of scaffolds, which are temporary construction structures, on the cost has an important place in today's competitive conditions. In order to be successful in the globalizing world, it has become essential to finish a job in the shortest time and at the best quality with minimum cost. Many parameters are taken into account when installing these structures, which require engineering knowledge and experience. Within the scope of this study, 3 different exterior scaffoldings consisting of wood, steel and aluminum in terms of material were modeled in the Sap 2000 version 23.2.0 program in accordance with the legislation and static analysis was made. Comparisons were made by finding the material-cost relationship in line with the sections determined as a result of these analyzes. When evaluated in terms of materials and workmanship, considering their useful life, it was seen that the scaffolding type with the highest cost was aluminum scaffolding, and the h type steel scaffolding with the lowest cost.
