Abstract
The construction industry, which has grown rapidly in recent years, has been under the
influence of globalization like other sectors. With globalization, the removal of borders and
increasing competition cause contractors to lose large-scale jobs due to very small cost
differences. For this reason, the importance of cost studies carried out during the project phase
is increasing day by day. This is a fact that project cost is extremely important for all sectors.
However, cost estimation and analysis studies have critical importance for the construction
industry due to the high costs in question.
In this study, the effect of supplier selection on project cost is analyzed for Turkish
construction sector. The aim of this study is to determine which criteria are important in the
supplier selection of the projects realized in the Turkish construction sector. Within the scope
of the study, a questionnaire was carried out with professionals in construction. The analysis
of the results reveals the most important factors in supplier selection and it is thought that it
will be beneficial to those related to this issue.
