Abstract: Design errors are a common issue in construction projects, leading to delays, cost overruns, and quality issues. The study evaluates the effects of design errors on construction projects in ten selected construction companies in Lagos State. In order to achieve the goal, the literature is extensively studied from numerous scholars and gathered primary data through a structured questionnaire. Out of the one hundred and twenty questionnaires distributed among Project Managers, Project Supervisors, Technical Staffs, and administrative staff, one hundred and seventeen were returned, coded, and analyzed using descriptive statistics, and mean and regression analysis. The study revealed that design errors lead to variation in the ending cost of a construction with coefficient determination (R2 = 0.389) given as 38.9%. Design error causes cost overrun in a construction project with the coefficient of determination (R2 = 0.423) given as 42.3%. Finally, design error brings up additional costs in a construction project given as 39.6%. Design errors have a profound impact on construction projects in Lagos State, resulting in significant delays, cost overruns, and quality issues. The study recommends improved design review processes, enhanced collaboration between designers and contractors, and adoption of Building Information Modelling (BIM) to minimize design errors.
