Impact of Precision on Working Drawing and Specification in the Nigerian Construction Industry

This study investigates the impact of precision on working drawings and specifications in the Nigerian construction industry, with a particular focus on the role of digital fabrication technologies. As working drawings and specifications serve as the backbone of project communication and execution, their accuracy is critical to minimizing errors, reducing delays, and improving quality on construction sites. A quantitative survey involving 539 construction professionals was conducted to assess perceptions of how tools such as CAD, BIM, and other digital methods influence documentation precision and implementation accuracy. The findings reveal that while digital fabrication significantly enhances the clarity, consistency, and constructability of construction documents, widespread adoption is limited due to high software costs, inadequate training, and resistance to change. The study draws on Information Theory and the Technology Acceptance Model (TAM) to explain the relationship between communication efficiency and technology adoption in the Nigerian context. It concludes that improving precision through digital documentation practices is essential for elevating standards in the industry, and recommends capacity-building, policy reforms, and stronger collaboration among stakeholders to promote a precision-driven construction culture.
