An analytical approach for explaining the variability in labour intensive construction operations has been developed. Data has been collected daily from 3 sites. Not only productivity but many of the factors affecting it have been measured. The quantification of the impact of each individual factor is based on the assumption that deviations from an operative's normal output arise because of disturbances imposed by a multiplicity of site factors. The impact of each individual factor causes the average daily productivity to change. Analysis of variance has been used to study the influence of the following variables on productivity of concrete casting. Cause of delay length of delay length of workday gang composition height of work area The objective of the research is to determine the productivity index (labour constant) and to identify factors which affect productivity. The ultimate use of productivity measurement is that of project control.
