Abstract
A successful construction project has many important components, one of which is labour. Many
construction projects fail to achieve their goal due to poor labour productivity. Thus, this research
evaluated labour productivity on building projects based on the perception of site managers. The
objectives identified the factors that affect the productivity of construction operatives, examined the
importance of factors affecting labour productivity, assessed the management policies to improve
productivity of workers on site, and suggested solutions to the problem of labour productivity on building
sites. The sample frame consisted of the 26 construction organizations registered with Lagos Chamber of
Commerce and Industry (L.C.C.I). Random sampling technique was used to administer 62 questionnaires
to site managers of the building projects of the 26 construction organizations in the frame. Data obtained
were analysed using frequency, mean and relative importance index. The findings showed that topmost
among the factors that affect labour productivity are clarity of technical specification, equipment
shortages, skill of labour, coordination level among design disciplines, payment delay, and material
shortage with mean values of 4.24, 4.20, 4.20, 4.17 and 4.17 respectively. Training, welfare amenities and
specialization with mean values of 4.36, 4.02 and 4.00 ranked highest among the management policies for
improving operatives’ productivity. It is recommended that operatives should have access to equipment;
payment should also be done promptly; in addition to organizations supporting operatives on regular
training on relevant skills
