    Quantity Surveying Practice and Evolution of SD Building Information Modelling
    (College of Engineering and Environmental Studies, 2016) Adebiyi, R.T; Babalola, M.O.; Amuda Yusuf, Ganiyu
    Manual quantification by Quantity Surveyors (QS) from two dimensional drawings is complex and prone to human error because of technological and organizational problems. Building Information Modelling (BIM) is an emerging technology with potentials for automation of quantity take-off and estimating process. This study examines barriers to five dimensional (5D) BIM adoption by Nigerian QS. Purposive sampling approach was used to administer questionnaire to practitioners in construction, consulting and clients' organizations in Nigeria. A total of 53 validly completed questionnaire were returned and analyzed using Statistical Package for Social Sciences. The five most important barrier factors to 5D BIM adoption by QS are: lack of collaborative initiatives from industry stakeholders; problems of communication and data sharing among firms; lack of government support and clear roadmap for BIM implementation; BIM model is not compatible with traditional take-over estimating software tools; and non-alignment of current rules of Building and Engineering Standard Method of Measurement. The 5-dimensiona/ BIM have tremendous potentials to increase the communication efficiency and interpretation ability of quantity surveyors. However, there is need for construction industry stakeholders to formulate strategies to develop and implement information exchange system that can support collaboration.
