Abstract

Delays are one of the most important problems in the construction industry, because delays in construction projects have negative effects on owners and contractors. The aim of this study is to evaluate the effects of scheduling on construction project delays. The methodology of this research was to use a questionnaire and analyze the results quantitatively. In this regard, fifteen companies were selected from the three groups of employer, consultant and contractor, and the prepared questionnaire was sent to 80 of their employees. Finally, 70 participants answered the questionnaires, and the obtained data were analyzed using SPSS statistical software. The results of the analysis show that the most important objectives of scheduling in construction projects are "resolving conflicts between suppliers or sub-contractors", "use as an effective project control tool" and "resolving delay claims". In addition, based on the evaluation, the importance of the initial schedule in construction, "timely completion of projects" and "ensuring customer satisfaction" were determined. Also, delays and disruptions in construction projects were recognized as the consequences of lack of scheduling in construction projects. Finally, it was concluded that to minimize delays and also to ensure timely delivery of the construction project, project objectives, importance and effects of scheduling are key factors that should be considered to avoid delays.
