Impact Assessment of Legal and Regulatory Compliance on Specification in the Nigerian Construction Industry
Main Article Content
Abstract
This study examines the impact of legal and regulatory compliance on specification practices within the Nigerian construction industry (NCI). Despite existing national building codes and professional guidelines, widespread non-compliance continues to cause structural failures, cost overruns, and delays. A quantitative survey was conducted with 506 construction professionals, including architects, engineers, builders, and project managers. Data were analyzed using descriptive statistics and correlation analysis to evaluate awareness, compliance levels, and the link between specifications and project performance. Results show that 62% of respondents acknowledged weak institutional enforcement as a major barrier, while 58% cited client-driven cost-cutting as a driver of non-compliance. Correlation analysis revealed a significant positive relationship (r = 0.46, p < 0.01) between regulatory compliance and project performance, underscoring the importance of adherence to specifications. The findings highlight gaps in enforcement, limited professional awareness, and the underutilization of digital compliance tools. The study recommends strengthening institutional oversight, adopting digital monitoring systems, and enhancing professional training to ensure that specifications consistently align with legal and technical standards. By addressing these challenges, Nigeria’s construction sector can improve safety, reduce project risks, and support sustainable urban development.
