Factors Affecing Labor Productivity on Con-Struction Sites in Addis Ababa , Bole Sub City
The construction industry is one of the major labor driven industry that contribute for the economic growth of a country. Labor productivity constitutes a significant part of production input for construction projects. In the construction industry, many external and internal factors are never constant and are difficult to anticipate. Working in improving labor productivity would help to improve the on time and on budget finishing of construction projects The objective of the study was to explain the various factors affecting labor productivity that have been identified by other researchers and select those factors that could suite this study and to evaluate and analyze the Relative Important Index (RII), evaluate the relation of these factors with productivity and make comparative analysis between the study findings and other countries findings. Literatures were reviewed and factors identified by early researches were considered to categorize the factors. 39 indicators, categorized into 7 factors, were analyzed. The study focused on labor productivity in construction performed by general contractors above grade 5 located in Addis Ababa Bole sub city which have ongoing construction project sites. The questionnaires were distributed to technical personals (Project Manager, site Engineer, forman, office engineers…) and skilled and unskilled labors. The study result indicates that the main factors affecting labor productivity are: Good site coordination, good communication between supervisor and labor, good site condition, supervision competency, project simplicity, increasing laborers in order to accelerate works, good construction methods, good relations between management and workers, good site layout and organization and organization and sufficient labor skills in descending order. Furthermore, from 39 indicators considered in the study were distributed among 7 major factors, which are ranked in importance order as management related factors, technical related factors, miscellaneous factors, manpower related factors, material related factors, plant and equipment related factors, motivation related factors. Also the study found out that all factors are correlated to productivity with positive influence with different significance rate.
