dc.description.abstractMechanical and electrical (M&E) services project is complex in nature and involves a large number of specialist organisations entering the project life cycle at different stages with different lines of relationships, responsibilities and risk management capabilities. Hence, a number of risk arises at the design and installation stages which results into poor cost and time performance in M&E services projects. This paper identified and rank the risk factors affecting cost and time performance of M&E services project. A total of 30 risk factors identified from preliminary investigations was adopted as basis for a questionnaire survey to industry practitioners in Nigeria. Mean response analysis was used to determined the probability and severity of the risk factors and risk impact scores was used to rank the relative importance of the risk factors. Analysis of variance (ANOVA) was used to investigate differences of opinions between respondents'. The study identified 23 risk factors (risk impact >3.5) impacting M&E service projects. Out of these risk factors, 7 has significant impact while the rest have moderate impact. The 7 risk factors in order of their significance are: high foreign materials content, poorly prepared tender document, late involvement of M&E engineers, non-involvement of specialist designers, government policy change, poor specification and poor coodination of design imputs. In addition, ANOV A results show that no significant difference exists among the professionals on these 7 risk factors. This suggests that the risk level of M&E services project is high. The identification and ranking of the risk factors has practical implication in M&E services project. The risk identification and ranking table is a good tool for assessment of risks related to M&E services at project inception. This will allow the client and contractor to understand the high risk areas in M&E services project and, where applicable, assign responsibility for those risks to the party or parties best situated to control them.en_US
