Abstract

Delays are one of the main problems in construction projects in developing countries, as cause a negative effects on the projects. Delays can be minimized only when their causes are recognized. The aim of this paper is to identify the main causes and consequences of delay in Iranian construction projects. The literature related the field of causes and effects of delay in construction projects has been reviewed from 2000 onwards. A questionnaire survey was conducted to solicit the causes and consequences of delay from consultants and contractors' viewpoint. This study identified 10 most important causes of delay from a list of 27 different causes of delay and 6 different effects of delay. It was found the predominant causes of delay are poor site management and supervision, delay in progress payment by clients, change orders by client during construction, ineffective planning and scheduling of project by contractor, financial difficulties by contractor, slowness in decision making process by client, delays in producing design documents, late in reviewing and approving design documents by client, poor contract management by consultant and problems with subcontractors. The results showed delay can lead to many negative effects such as time and cost overrun, disputes, arbitration, total abandonment and litigation. The paper forecasts some future trends and suggests certain areas in which future research on construction projects could focus on. Although the research is devoted to Iran's specific case, the findings of construction management problems are common to developing countries.
