In this research, factors affecting construction labour productivity in Zaria, Kaduna state was assessed. The research seeks to identify the factors affecting labour productivity in the research area. It is believed that this information will aid site managers and the construction professionals on decisions to take in-order to limit these controlling factors thereby leading to an improved level of efficiency in labour force, increase product labour productivity and reduce cost and time over runs on construction projects. The research adopted a quantitative research approach with the use of questionnaires as an instrument for data collection from site managers at construction sites in Zaria. Sixty-seven questionnaires were administered on construction sites within Zaria and Forty-one were returned giving a sixty-one percent response. The Questionnaire sought to assess the perception of site managers on factors affecting construction labour productivity. Data was analysed using descriptive statistics analysis to obtain frequencies, mean and Relative Importance Index (RII). RII was used to rank the factors. Thirty-Nine out of the Forty-One factors researched indicated high severity with the RII ranging between 0.60 RII < 0.80. The research revealed that external forces tend to affect construction labour productivity more than Site factors and Human Labour Factors. This can be attributed to the fact that site factors and Human Labour factors can be controlled by the site engineers while the external factors cannot be really controlled by the site engineers. The survey also revealed that Rain, Conflict with project stakeholders, Skill of labour, and Financial Crisis had a very high severity in affecting construction labour productivity on the construction sites in Zaria, Kaduna State.
