Risk Factors Affecting in Highway Construction Project
Reshma.P | Sreechithra.P
Abstract: Highway construction projects carry some substantial risks. The main aim of this paper is to identify the most significant risk factors affecting highway construction project in Manjeri (Malappuram-Kerala) SH71 & to decrease the probability and impact of those risks. The research method begins with extensive literature review to provide a prime risk factors list which was also to reach final risk factor list which contains all risks that may be faced during highway construction. Subsequently, a set of 10 risk groups consisting of 34 risks was selected and a questionnaire survey was conducted to determine the likelihood and consequences of the identified risks. A questionnaire is then developed to the opinion of construction professionals (Engineers, Contractors, Stake holders, Overseers and Supervisers) as to the probability and impact of those risks. Twenty surveys were completed and used in the risk analysis. The priority of each risk is calculated by multiplying the probability with the impact for each risk. The priority helps identify the most significant risks. The relative importance index (RII) for the risk priority is calculated based on all responses for each risk. The most significant risks include Existing traffic, unexpected ground utilities, delays in payment, inadequate claim administration, quality and integrity of design, delays in approvals, and delays in expropriations. Existing traffic is the most important risk in Manjeri highway construction
