Loss Assessment Of Construction Equipment Productivity And Its Impact On Equipment Financial Performance In Federal Road Projects A Case Study On Three Federal Asphalt Road Projects In Snnpr

Modern construction, characterized by effective and efficient utilization of constructionrnequipment to accomplish numerous construction activities. Equipment may range from simplernhand tools or apparatus to heavy-duty construction equipment. As a high level of productivityrnis important to any company’s success and survival, this paper help to fill the gap created byrnthe absence of proper equipment management on the construction sites and helps to examinernthe overall performance of heavy-duty construction equipment. This study also examines thernmajor contributing factors for productivity loss on the case study federal road constructionrnprojects to find important interventions for changes; this is because machinery managementrnhave high influence on productivity, cost and quality. Three federal roads where involved in thisrnstudy, Namely, Mazoria-Durame-Hadero, Hadero-Durgi and Alaba-Alemgebeya-Hulbarek roadrnprojects in the southern regional state of Ethiopia. The assessment involved in this study wasrnfield observation and measurement to quantify downtime and the actual productivity and deskrnstudy to identify main factors contributing for productivity loss. In the entire study site, the OEErnindex show low percentage of productivity in between 55% to 68%. Out of the three primaryrncomponent rates of OEE index only quality rate have a higher performance, which is about 90%rnand above. However, the performance rate in the entire study site shows lowerrnperformance(less than 76%). Due to this weak performance of the construction equipmentrnproductivity, the contractors forced to incur an additional cost from 1 – 2 % of the totalrnmonthly running cost allocated for the equipment. Out of the four main contributing factors forrnequipment productivity loss (machine factor, human factor, management factor and workrnfactor) the management problem ranked first. Although there was low construction equipmentrnproductivity in the entire study site, the Resident Engineers (RE) do not have any compliant onrnthe contractor regarding to their poor Performance.rnKeywords: Overall Equipment Effectiveness, Performance Measure, Productivity,rnConstruction Equipment, Equipment ManagementrnSchool of Graduate studies-
