Abstract
Construction labour productivity has continued to be investigated because of its
importance in national economies. This study assesses and compares the relative effects of
labour-related factors on construction labour productivity across the six geographical states
that comprise the south-south zone of Nigeria from the perspectives of building craftsmen
and project supervisors/engineers. A field survey involving a stratified random sample of 1,138
building craftsmen and 561 project supervisors/engineers was conducted. Data were
collected through structured questionnaires and analysed using mean item scores, KruskalWallis H-tests and Mann-Whitney U-tests. The results show that there is no significant influence
of labour-related factors on construction labour productivity across geographical states,
especially when they seem to be similar in terms of contiguity, linguistics, ethnicity, cultural
practices, climate and socio-economic conditions. The two groups of respondents also
agreed on the relative effects of labour-related factors on construction labour productivity.
This study concludes that, when project locations are similar, labour management practices
and productivities do not vary. 13 opportunities related to the management of labour for
productivity improvement on building sites were emphasised. The study recommends that
improved labour management practices are a potent productivity improvement strategy
that will enhance construction labour productivity
