Abstract
Modern construction, characterized by effective and efficient utilization of construction
equipment to accomplish numerous construction activities. Equipment may range from simple
hand tools or apparatus to heavy-duty construction equipment. As a high level of productivity
is important to any company’s success and survival, this paper help to fill the gap created by
the absence of proper equipment management on the construction sites and helps to examine
the overall performance of heavy-duty construction equipment. This study also examines the
major contributing factors for productivity loss on the case study federal road construction
projects to find important interventions for changes; this is because machinery management
have high influence on productivity, cost and quality. Three federal roads where involved in this
study, Namely, Mazoria-Durame-Hadero, Hadero-Durgi and Alaba-Alemgebeya-Hulbarek road
projects in the southern regional state of Ethiopia. The assessment involved in this study was
field observation and measurement to quantify downtime and the actual productivity and desk
study to identify main factors contributing for productivity loss. In the entire study site, the OEE
index show low percentage of productivity in between 55% to 68%. Out of the three primary
component rates of OEE index only quality rate have a higher performance, which is about 90%
and above. However, the performance rate in the entire study site shows lower
performance(less than 76%). Due to this weak performance of the construction equipment
productivity, the contractors forced to incur an additional cost from 1 – 2 % of the total
monthly running cost allocated for the equipment. Out of the four main contributing factors for
equipment productivity loss (machine factor, human factor, management factor and work
factor) the management problem ranked first. Although there was low construction equipment
productivity in the entire study site, the Resident Engineers (RE) do not have any compliant on
the contractor regarding to their poor Performance.
