Abstract
Innovative technologies are inevitable in the construction industry. Building information modelling (BIM) has been noted to be the most influential innovative technology within the construction industry; as such it is important that this technology is deeply studied to ensure a higher level of understanding and enhance adoption level. However, the adoption of BIM differs owing to different dimensions related to this innovative technology. Therefore, this study focuses on the fifth dimension (5D) of BIM. The 5D BIM comprises the three crucial parameters of the construction projects, namely the design, time, and cost. Nevertheless, the adoption of 5D BIM has been noted to be relatively slow in the South African construction industry. Consequently, the study's main aim was to assess the adoption level of 5D BIM in the South African construction industry. To achieve the study aim, a quantitative research approach was utilised. A well-structured questionnaire was distributed amongst the construction professionals as the primary method of data collection, while the in-depth literature review was a secondary method of data collection that informed the developed questionnaire. Exploratory factor analysis (EFA) in conjunction with descriptive analysis were utilized to present the results of the data collected. The findings revealed that poor finances within the South African construction industry are the key to a low level of adoption of 5D BIM in construction projects. The findings further revealed that the key element to improve the adoption of 5D BIM is to enhance the support from the stakeholders through investment to utilise this innovative technology in South African construction projects. It has been concluded that innovative technologies play a significant role within the construction industry and have evolved the methods of executing construction projects. As such, the re-skilling of construction professionals is key as it will improve the adoption of this innovative technology. It is therefore recommended that the funds be made available to upskill the construction professionals to fit into the system of this innovative technology with adequate knowledge and skills.
