Construction productivity is rarely analysed in Iran. If productivity is to improve, current weaknesses must be identified. To this end data were collected through a structured questionnaire survey. By utilizing the relative index ranking technique, the identified problems were prioritized for detailed analysis and discussion. Results indicate that the five highest-ranking problems are: Materials shortage, weather and site conditions, equipment breakdown, drawing deficiencies/change orders, and lack of proper tools and equipment. Devastating war with neighbouring Iraq has led to a boom in construction activities leading to shortages of construction materials. The casual employment of the majority of construction operatives and poor managerial skills are the significant contributors to low productivity on Iranian construction sites.
