Risk management in high voltage power transmissionline construction projects in Sri Lanka

Abstract

Electricity is an essential element in economic growth and socio-economic development of a country. High Voltage Power Transmission Lines (HVPTL) are used to transmit the electric power in bulk from generating stations to substations. HVPTL construction projects are inherently riskier than most of the other types of construction projects. In Sri Lanka the knowledge, practice and application in the particular area is in minimum level. Therefore, this research aims to establish a systematic study on managing risks in HVPTL projects in Sri Lanka, which will ultimately help the project teams to manage risks effectively. The collected empirical data from expert interviews and two rounds of questionnaire surveys were analyzed using content analysis and descriptive statistics respectively. The results of the study initially identified forty-eight (48) risk factors related to HVPTL projects, of which fourteen (14) risk factors were selected as the most significant risk factors. “Delay in project deadline” is the top most critical factor in HVPTL projects according to results. The risk factors are mainly allocated client and contractor or shared between them. The widely used risk response measures and most suitable risk response measures in order to manage those most significant risks were identified. The challenges against following the proper risk management process were checked and it was found out that the “lack of awareness” is at the prime reason. Finally, it is recommended to use more proactive approach in risk management for early identification of risks and for better responses and raise the awareness of stakeholders on the importance of the proper risk management practices.
