Abstract

The
concept of time-cost relationship in construction projects was first introduced
by Bromilow. Bromilow used the data of the superstructure projects completed in
Australia in the creation of the proposed time-cost model (BTC model). The aim
of this study is to determine the time-cost relationship of superstructure
projects in Turkey. Time and cost data of superstructure projects completed
between the years of 1999-2018 was used in the study. Data was grouped
primarily on the basis of the intended use of buildings (individual buildings, educational
buildings, hospitals, industrial buildings and social housing), and then
time-cost relationships were separately determined for each group. In addition,
the effects of the parameters such as exchange rates and the number of
non-working days on the time-cost relationship were investigated statistically.
