Abstract
Delay in construction projects is a major concern. Research was conducted to find the construction delay causes and mitigation measures. Literature reveals that different countries experience various causes of delays and significances of these causes are different based on project types. This study explores delay causes in Kazakhstan’s construction industry and analyzes their influence on different types of construction projects. Fifty-five delay causes relevant to construction projects in Kazakhstan have been identified through literature review and primary interviews with selected construction professionals. Afterwards, a comprehensive survey was conducted among the industry professionals. The survey results show that different delay causes have different importance based on the project types (industrial, residential, commercial, etc). Moreover, project parties (client, contractor and consultant) have different views on the delay causes. Accordingly, the study ranks delay causes based on project parties and project types and compares their correlations. Finally, recommendations for the most prominent delay causes have been provided. This study provides better understanding on delay causes and gives important guideline for stakeholders of Kazakhstani construction industry and other construction professionals in the world to control their projects. Similar studies can be conducted in other countries to identify causes and remedial measures for delays.
