The construction industry in Afghanistan faces challenges such as cost overruns and delays. To overcome these problems, nowadays, implementing risk management in construction field has shown improvements in the mitigation of risks which have adverse impacts on project objects such as time, cost and quality. Risk assessment process is executed as part of risk management for uncertainties that construction sector confronts in Afghanistan.21 most significant risks were identified, analyzed and evaluated using 5x5 probability matrix method. It was found that 20 out of 21 risks fell into the unacceptable and unwanted category. These risks require mitigation measures by executing risk treatment policy and need be to registered, monitored and reviewed before and during the construction phase. The findings call for necessary awareness in developing the Afghanistan construction industry’s capability and performance to execute risk management for mitigating against further project failure.
