Abstract:
Construction is one of the major economic sectors through out the world. The sector
consists different mega structures in which varaitey of heavy duty machines and
equipments are used during the course of the construction. Construction of road projects
is one of the sector where different heavy duty equipments is utilized for execution of the
work. However, the construction of many road projects is refrained due to multifaceted
problems encountered in the course of construction. Equipment productivity is one of the
significant factors affecting the successful completion of a project. Though the factor
affecting equipment productivity in road construction cannot be avoided, they can be
minimized by adequately identifying the factors that cause loss of equipment productivity
in road construction projects. We all dream of a road construction project completed with
the specified scheduled time and budget, but usually, it is not achieved due to several
factors that affect the project. The general objective of this study is to assess the factors
affecting the productivity of earthwork equipment in Addis Ababa City Roads
Authority. The research works briefly to determine the factors affecting earthwork
equipment productivity in Addis Ababa City Roads Authority Projects by checking the
efficiency of earthwork equipment productivity. Moreover, it assesses the effect of
earthwork equipment efficiency on the progress of a road project. The research method
used is a purposive sampling. Questioners, critical observation, and focal group
discussion are the tools used in collecting the data. Based on the collected data and the
analysis made, the research identified the following factors as the factors affecting
earthwork equipment productivity. These are Environmental Factor, Management
Factor, Operator Factor, Equipment Factor and Technical Factor Moreover, efficiency
of the equipments is calculated to check the productivity of the equipments and to identify
the factor for loss of productivity.In the research, inorder to enhance equipment
productivity proper supply of spare parts for the equipmentst, providing of trainee to the
management staff and operators, providing of incentive and recognition to the project
staff , updating technical knowledge of the operator ,and systematic organization of the
garage and the equipment adminstrtation is recommeneded.
