ABSTRACT The need for increased productivity in the construction industry has become a great concern for industry stakeholders. Decline in productivity is induced by several factors resulting to increased wastage, time overruns, reworks, cost overruns, and hostile relationships between project stakeholders. Building Information Modelling is gradually being implemented by major countries across the globe. The move to adopt Building Information Modelling in Uganda’s private and public sector and amongst different building professionals has been very slow. This is unfortunate because many QS firms in Uganda have not broadly utilized and appreciated the positive changes and advantages that the new technology could provide in their profession. The aim of this research was to determine the level of awareness, usage as well as the benefits and constraints of Building Information Modelling in the quantity surveying practice. This study used qualitative methods which included questionnaires and analysis of secondary data. The Likert scale format was used for the purpose of design the questionnaire. Simple random sampling was used to select the 63 Quantity surveyors to which questionnaires were administered. To better understand BIM, this paper outlines what BIM is and its characteristics, includes a description various challenges associated with BIM adoption practices. It also includes what opportunities BIM presents to the quantity surveying profession and a graphical presentation of the most significant challenges and the benefits that arise when using BIM. The most significant challenges were unawareness of benefits BIM can bring to projects, high costs of BIM adoption. The most significant benefits were improved Quality of work and increased Productivity However, BIM should be adopted because of its great potential for integration into the life cycle of construction projects. Hence it would be a fundamental tool in project procurement in the near future. Keywords: Quantity surveying; BIM; Building Information Modelling; Uganda.
