Building Information Modelling in quantity surveying practices: current state and future challenges in Hong Kong

The use of building information modelling (BIM) in recent years has accelerated the performance and productivity of the architecture, engineering, and construction (AEC) industry. BIM can promote lean management, with enhanced control over budget and cost. However, the application of BIM for quantity surveying (QS) practices has not been extensively explored. Thus, this study examined the current situation and future challenges of BIM adoption in QS practices in Hong Kong. Questionnaire surveys and semi-structured interviews were administered to obtain insights from AEC industry practitioners in Hong Kong. Sixty survey respondents and nine interviewees participated in this study. The participants were quantity surveyors from developers, consultancy firms, and contractor companies. Results suggest that quantity surveyors are increasingly adopting BIM in Hong Kong. However, the low quality of BIM models and improper implementation of BIM often limit BIM adoption in QS practices. Another critical challenge is the absence of well-recognised BIM standards. Moreover, the shortage of skilled BIM professionals jeopardises the development and adoption of BIM in QS practices. The findings highlight the current achievements and barriers associated with BIM adoption in QS practices in Hong Kong. Prerequisites for successfully applying BIM in QS practices are suggested herein.
