ABSTRACT

The aim of this project was to carry out risk analysis in managing Engineering Facility during Covid-19 crisis-a case study of the Mife Construction Nigeria Limited located in Port Harcourt. The analysis was carried out among workers in four units which include asphalt unit, purchasing, maintenance and workshop units. The analysis explored perception, awareness and practice of Covid-19 management among workers managing Engineering Facility. Data was obtained from these units via questionnaire method and SPSS tool was used for the computation. Both probabilistic and deterministic methods were used to analyse the risk exposures. Reliability indices which include mean, variance, probability and standard deviation and regression model were used to determine the coefficient of variation while the FOSM was used to determine the reliability index. Risk exposure of workers for the four units: Asphalt, Purchasing, maintenance and Workshop are 0.7095, 0.9971, 0.7002 and 0.6579 respectively. The probability of safety was also evaluated for the four units as Asphalt = 0.761, Purchasing = 0.840, Engineering = 0.758 and Workshop = 0.745 respectively. The acceptable probability of safety is greater than or equal to 0.9, it was observed that only the Purchasing Unit had a very close value to the probability of safety and it is considered to have the highest probability of safety or reliability while Workshop Unit had the lowest probability of safety and it is therefore considered to be at risk in managing the spread of Covid-19.
