Abstract
Nigeria's construction industry is facing significant challenges such as low productivity, high costs, and poor quality of buildings, and adoption of Building Information Modelling (BIM) can address these issues, but its adoption has been very slow in Nigeria. This paper aimed at investigating the level of awareness and usage of BIM, factors affecting the adoption, socio-economic benefits of its adoption and barriers and challenges affecting the adoption of BIM in Abuja, Nigeria. 363 structured questionnaires were administered on civil, mechanical & electrical engineers, quantity surveyors, architects and builders in Abuja, out of which 249 valid responses were received and the data obtained was carefully analyzed using descriptive analysis, relative importance index, and mean item score. While 87.95% of the respondents claim that they have heard the BIM concept before, only 19.27% rate their usage and knowledge of BIM as high or very high, this shows that most of the respondents currently do not use BIM in their day-to-day activities. The study shows that BIM education, affordability, ability to gain competitive edge, vision from management and ease of use as some of the most important factors affecting the adoption of BIM in Nigeria. It also highlighted the improvement of visualization & design review, reduction in risk level, improvement of quality, productivity, client satisfaction and project documentation as the most important benefits derivable from the use of BIM. The paper also shows that high cost of training, lack of government support, lack of education, information, investment, ICT infrastructure, power supply and demand from clients as the most important challenges hindering its adoption in Nigeria. The Nigerian construction industry may realize the benefits of BIM in terms of improved project outcomes, increased productivity, and increased efficiency by overcoming these barriers and encouraging a collaborative approach. Key suggestions for enhancing BIM adoption in Nigeria were made in this paper, including but not limited to incorporating BIM into curricula for the built environment, providing professionals with awareness programs and training and establishment of national BIM standards by the government.
