Özet

The goal of this study is to determine the relationship between height and building unit cost (i.e., cost per gross floor urea) for high-rise buildings and to identify the effect of footprint area of buildings to this relationship, Previous studies an height and unit cost relation of high-rise buildings are Limited and mostly do not discuss the details of the height-cost relationship with respect to elemental costs Or major work costs, In this study the relation between height and unit cost were analyzed by examining the cost data of 65 high-rise (between 25 m and 142 in) residential buildings that were built with tunnel form between the years 2006 and 2013 in Istanbul, The results demonstrate that the total cost of the building, elemental costs (e.g., substructure), and some major work (e.g., concrete) change with height, Similar to the prior studies in the literature, the cost-height relationship identified in this study has a U-shaped came; however, the bottom-out point is around 65 at, Resides determining the hetyht-cost relationship, another contribution of this study is investtqution of the effect of footprint urea on the cost-height relationship, For buildings with small and large footprint areas, cost-height relationship is U-shaped, while for buildings with medium footprint areas unit cost increases as the height of the building increases, Results also show thu t the unit costs of buildings with medium-size floorprint areas ore lower than that of the buildings of the same height hut with 'urger footprint areas, The findings of the study can he used by academicians, architects-engineers and practitioners to understand the cost-height fUotprint area relationship and to make more cost-effective decisions about the hetyht and footprint urea of u building, especially in areas where height restrictions do not exist.
