Evaluating The Benefits of Prefabricated Construction Systems in Enhancing Project Speed, Cost Efficiency, And Quality Control in Modern Building Projects in Lagos, Nigeria
Abstract
The construction industry in Nigeria faces persistent challenges of project delays, cost overruns, and inconsistent quality, particularly in rapidly urbanizing Lagos. Conventional on-site construction methods are constrained by labour inefficiencies, weather dependency, and material wastage. Prefabricated construction systems offer an alternative approach through off-site manufacturing and controlled assembly. This study evaluates the benefits of prefabricated construction systems in enhancing project speed, cost efficiency, and quality control in Lagos. A mixed-methods research design was adopted, combining quantitative data from structured questionnaires administered to 120 construction professionals with qualitative insights from semi-structured interviews. Descriptive and inferential statistics were employed for quantitative analysis, while thematic analysis was used for qualitative responses. Findings reveal that prefabricated construction systems significantly reduce construction duration through parallel off-site production and on-site activities, enhance cost efficiency by minimizing material waste and labour requirements, and improve quality control through standardized manufacturing. However, challenges such as high initial capital investment, limited technical expertise, logistical constraints, and low stakeholder awareness were identified as key barriers to widespread adoption in Lagos. The study concludes that prefabricated construction systems offer substantial performance advantages over conventional methods. It recommends policy support, professional training, and pilot projects to facilitate broader adoption within the Nigerian construction industry
