An evaluation of the critical factors influencing productivity of masonry work in construction sites in Kano, Nigeria

Abstract

Construction labour productivity is of great interest to practitioners and researchers because it affects the performance and success of the project. This research assesses and ranks factors that critically influenced productivity of masonry work for some selected within Kano metropolis, Nigeria. A total of sixty three (63) respondents which include construction experts from lower to top management levels of various positions were selected. Structured questionnaire related to masonry labour and productivity was distributed to the selected respondents. The four most critical factors that negatively influence labour productivity of masonry as identified by the respondents work were found to be delayed in payment process. Payment process discourages some qualified contractors from bidding for the job, material quantity which result in stoppage of material delivery, security of life and property. Security as a constraint has negative and significant influence on the program of projects and worker experience. Lack of labour
experience has a very high effect on productivity; experience improves both intellectual and physical abilities that improve productivity.
The inferences drawn from this study could be used by the project managers to take account of these factors at an early stage in order to improve labour productivity of workers on construction site in Nigerian.
