This paper is based on research aimed at evaluating construction labour productivity
with the view to improving construction industry performance in Tanzania.
Comparative analysis of macro-productivity with Kenya, and UK over a 25 year period
indicated a downward trend. Analysis of site based productivity data indicated a wide
variability and that its distribution was skewed to the left suggesting that productivity
was low for most of the operatives. These characteristics were indicative of the
productivity improvement potential in ~e building construction industry. This paper
follows on from these findings by .discovering some of the possible factors contributing
to the variability through an opinion survey involving key construction process owners.
The paper reports on productivity factors as perceived by construction operatives. A
total of 50 operatives were interviewed to provide their ratings on the influence of
predetermined factors on their productivity. An evaluation of the results indicated a
high degree of consistency. The ratings were then used as a basis of general ranking of
the factors. An independent sample of 40 operatives' opinion was used to validate the
results. The operatives' ratings were then compared with results of an opinion survey
amongst contractors. A detailed description of the statistical tools and procedures used
in the analysis is presented.
