Statistical evaluation of the relationship between delay time and project factors in construction projects: Case of Turkey

The most important problem in construction projects which have an important place in national economies are delays. In particular, the elimination or reduction of these problems for the countries recording large growth in the construction sector is very important in terms of time and cost savings. Determining the project factors that will cause the delay and taking protective actions accordingly will help to reduce the impact of the above given negativ points. In this study; The causes of delay were determined and 31 delayed causes and 89 participants were surveyed and the results of the survey were analyzed by factor analysis. Later, in Turkey placed 74 public and private sector construction projects in our country with the data received from construction projects to their cause delay in project factors have been identified and this project factors with significant association rules applying coexistence algorithm to determine the relationship between the delay time has been determined. Extracted through the rules again, in this study, proposals have been made to reduce delays. Keywords: Construction projects, Delay analysis, Survey, Factor analysis, Association algorithms.
