Sažetak
Despite the potential of various methods for calculating construction duration, few studies have focused
on the application of these methods in the tender preparation stage, and even fewer have focused on their application in public housing projects. Moreover, research
related to construction duration in Turkey has indicated
that considerable delays occur in public housing pro
jects. Therefore, we investigated the factors affecting the
construction duration of housing projects and developed
a novel calculation method for estimating the ideal construction duration. Data on public housing projects were
obtained from a major Turkish construction authority. Statistical data analysis was performed using multiple linear
regression analysis, chi-squared automatic interaction
detection (CHAID), and classification and regression tree
(CART) methods. The results revealed that several factors
significantly affected the ideal construction duration for
each statistical method. The cutoffs and standard errors
were calculated to test the validity of all three statistical
methods. The regression formula indicated statistical significance when the calculation method was tested. The
implementation of the methods for other public housing
projects significantly reduced the number of delayed pro
jects. The findings of this study are expected to contribute
by way of enabling senior project managers to estimate the
ideal construction duration for housing projects during
the tender preparation stage.
