Abstract: Abstract This study examined the utilisation of automation and robotics in optimising construction labour costs in Lagos State, Nigeria. A descriptive survey research design was adopted, and data were collected from 65 respondents comprising building professionals, contractors, and homeowners using a structured questionnaire. The data were analysed using mean, standard deviation, and Analysis of Variance (ANOVA) at a 0.05 level of significance. The findings revealed that automation and robotics significantly reduce construction labour costs by improving productivity, minimising delays, reducing errors, and enhancing overall project efficiency. However, their adoption is constrained by factors such as high initial costs, lack of technical expertise, inadequate infrastructure, limited awareness, and insufficient government support. The ANOVA results indicated a significant difference in perceptions regarding the benefits of automation but no significant difference concerning the challenges affecting its adoption. The study concludes that while automation and robotics offer viable solutions to rising labour costs, addressing the identified barriers is essential for their effective implementation. The study recommends policy support, infrastructure development, capacity building, and increased stakeholder awareness to facilitate the integration of automation technologies in the construction industry.
