Causes of Delays in Iranian Construction Projects

Abstract

Many construction projects are carried out around the world but only some of them are completed on time. Many factors indicate the success of a project such as: completion on time, within budget, within specified quality, satisfaction of the client, and the rate of change order. Delays in a construction project can be regarded as failure. This paper aims to investigate the causes of delay in Iranian construction projects. This research was conducted by questionnaire survey to solicit the causes of delay from the viewpoints of clients, consultants, and contractors. One hundred and twenty five sets of questionnaires were distributed to the respondents. The results demonstrate that finance and payments of completed work, improper planning, site management, contract management, and lack of communication between the parties are the key reasons for delay.
