This study investigated the level of utilisation of Building Information Modelling (BIM) and users’ perceived ease of use (PEU) and perceived usefulness (PU) of using BIM for performing quantity surveying tasks to formulate strategies to increase the utilisation of BIM.
A mixed-method approach, integrating quantitative and qualitative data collection, was adopted in this study to obtain a comprehensive understanding of usage of BIM in contractors for performing quantity surveying tasks.
The usage of BIM in contractors in executing quantity surveying tasks remains low, despite positive PEU and PU of using BIM. Utilisation of BIM for quantity surveying tasks has a positive correlation with PEU and PU, suggesting opportunities to enhance PEU and PU to drive BIM utilisation. Effective BIM modelling team, organisational support, outreach and government mandates are identified as critical strategies in motivating BIM use for quantity surveying tasks.
This study focused on the PEU and PU of technology acceptance model (TAM). There are other constructs of TAM that might influence the BIM utilisation for quantity surveying tasks in contracting firms.
Based on the finding, strategies are recommended to motivate the use of BIM in contractors to perform quantity surveying task.
These findings contribute to the TAM by highlighting the essential role of external support systems in shaping user perceptions and acceptance of new technologies. By identifying strategies that enhance PEU and PU, this research enriches TAM and provides actionable insights for optimising BIM utilisation for quantity surveying tasks among contractors.
