Abstract:
Labour productivity has been held responsible for the success or failure of construction projects
in the urban areas in Kenya and beyond. Without standardized metrics for measurement of
labour productivity, it becomes difficult or outrightly impossible to estimate the exact cost of a
project for both contractors and clients thus leading to escalation of costs, loss in profits,
increase in project execution time, stalling of projects and loss of confidence in the construction
industry. This research explores the factors affecting construction labour productivity amongst
practitioners in Nairobi and on projects within Nairobi. It establishes a definition of the term
and evaluates available literature. It then measures through a survey, the effect of information
flow on construction Labour Productivity at project level. Five factors are concluded to be critical
in project level CLP. The study also provides recommendations on how to manage CLP issues
within the industry to increase this productivity
