A STUDY OF BIM CAPABILITIES FOR QUANTITY SURVEYING PRACTICE IN NIGERIA

Purpose: This study investigates the impact of Building Information Modelling (BIM)–based cost estimating software on quantity surveying (QS) practice in Nigeria. It aims to evaluate the level of awareness, usage, and efficiency of BIM in cost management, while also identifying barriers and recommending strategies for wider adoption in the Nigerian construction industry.

Design/Methodology/approach: A descriptive survey research design was adopted, targeting construction professionals such as quantity surveyors, engineers, architects, and project managers. Data were collected using structured questionnaires, with responses analysed through Mean Item Score (MIS) and Pearson correlation tests using SPSS and Microsoft Excel. The reliability of the instrument was confirmed with a Cronbach’s alpha value of 0.96, indicating a high degree of internal consistency.

Findings: Results revealed that while 96.3% of professionals were aware of BIM, only 36.2% actively used it for cost estimation. A slight majority (55.9%) had adopted BIM-based estimation methods, while 44.1% continued to rely on traditional approaches. Autodesk, QS CAD, and Revit were the most recognised software. BIM demonstrated significant positive impacts on cost accuracy, planning efficiency, collaboration, and timely project delivery. However, challenges such as high training and implementation costs, lack of skilled personnel, inadequate ICT infrastructure, and resistance to change hindered broader adoption.

Research Limitations/Implications: The study was limited to a relatively small sample size and focused mainly on professionals within Nigeria. Broader regional comparisons and longitudinal studies could provide deeper insights into BIM adoption trends across developing countries.

Practical Implications: The findings highlight the need for investment in training, supportive policies, ICT infrastructure, and affordable software solutions to enhance BIM integration in cost estimation and QS practices.

Originality/Value: This study provides empirical evidence on BIM adoption in Nigeria’s QS practice, offering actionable insights for policymakers, construction stakeholders, and professional bodies seeking to bridge the gap between traditional and modern cost management practices.
