Assessment of equipment productivity in building construction projects in Uganda

Abstract

Management of construction equipment in building construction projects is an important factor to run projects in a successful manner. The focus of this study was to identify the factors affecting equipment productivity, to establish how these factors impacted on equipment productivity, with the aim of improving equipment productivity in Uganda. Using a cross sectional study design, data were collected from a total of 340 respondents in different construction sites in Kampala by use of questionnaires. Descriptive statistics were used to analyse the respondents' demographic characteristics and the mean and standard deviation was used to identify factors affecting construction equipment productivity. The identified factors were subjected to regression analysis and a model was developed to improve equipment productivity. The study established that human resource factors affecting equipment productivity were; technical skills of staff, experience of the operator, and motivation of staff. It was further established that equipment factors affecting equipment productivity were; equipment break down, quality of equipment, working cycle capacity, and age of equipment. With regards to the environmental factors affecting equipment productivity, the study found that weather conditions and access, were the leading factors affecting equipment productivity. It was established that holding other factors constant, environmental factors affect equipment productivity by 6.4% and the remaining 93.6% is explained by other factors. Project managers should therefore hire experienced and well-motivated equipment operators and in order to improve equipment productivity in building construction project.
