Özet:

Economy reduces the cost of the resources used to achieve the planned results or outputs of the designed building, considering the appropriate level of quality. In other words, it is to provide the most appropriate input at the lowest cost. The construction cost consists of various stages during the building process. In this study, a comparative study was made in terms of the structural design and initial construction cost of a building assumed to be located in an earthquake zone according to the regulations. A Building which belongs to a reference building of two floors, detached (not surrounded by any building in any side), total area of 566 square meters, without basement. According to this project, which considered as a reference, two different structural alternatives to the building were created. The first alternative is of the masonry building type (besieged masonry building). The supporting walls of these structures are made of cut basalt stone and are surrounded by horizontal and vertical reinforced concrete beams. In this building solid concrete slab system with a thickness of 12 cm was considered. In the second, reinforced concrete considered with the same architectural features as the first structure. Based on TBYD 2018, these two alternatives are taken as the ZB floor class. For each alternative, the quantity cost-based calculation and the material-based calculation were calculated separately. As a result he cost values of the mentioned alternatives have been determined as 752.9 TL/m2 and 553.51 TL/m2, respectively, for the rough construction unit cost for reinforced concrete and masonry models, respectively. The fact that the amount of reinforcement and concrete in the reinforced concrete structure model is relatively higher than in the masonry model has been an important factor in the unit cost.
