Guideline to minimise and mitigate technical risks in road projects: contractor's perspective in Sri Lanka

Abstract

This study investigates technical Risk (TR) management strategies for Road Construction Projects (RCP) in Sri Lanka from the Contractor's perspective. A comprehensive literature review was conducted to identify the technical risks in construction projects. A qualitative approach was conducted using two interview stages as the data collection method. Interview Stage I employed five (5) preliminary interview and Interview Stage II employed thirteen (13) semi- structured interview with experts. The collected data were analysed using content analysis, both manually and using NVivo software. The findings showed Eighteen (18) TRs for RCPs in Sri Lanka. Further, the study demonstrates the causes and consequences of TRs in Sri Lankan RCPs. Eventually, the study proposes mitigation strategies for the consequences. Overall, this research determines how to minimise and mitigate the TRs in RCP in Sri Lanka; thus, it is the study's novelty. Future studies can be conducted for the same study in different phases of construction phases, and different perspectives of the stakeholders.
