Abstract
This study employs an integrated approach of questionnaire survey and case studies to identify the key factors contributing to time delays and cost overruns in construction projects in Afghanistan. Initially, a comprehensive list of 78 factors was compiled and evaluated through a questionnaire survey. Based on the survey findings, the topmost critical factors are security issues, variation in quantities and extra works, corruption and bribery, improper project feasibility study, and adverse weather conditions. Subsequently, ten case studies were conducted to validate the questionnaire findings, revealing a higher prevalence of time delays over cost overruns and uncovering additional influential factors. Importantly, the study highlights the significance of security concerns and instances of corruption and bribery in Afghanistan compared to other regions. The findings of this research offer valuable insights to project stakeholders and policymakers in improving project success rates and mitigating time delays and cost overruns.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
