Comparison Between the Constraints of Building Information Modelling (BIM) and 3D Modelling

Abstract

This new emerging and innovative concept of Building Information Modelling (BIM) has delivered changes in terms of the efficiency and effectiveness of management in the construction industry. However, several constraints in the implementation of BIM are indicated notably people, process and technological constraints. In Malaysian quantity surveying profession, several quantity surveying firms are developing 3D model for taking-off and cost estimating preparation based on the standard method of measurement owing to the infancy stage of BIM implementation. This is still not a conventional work task in the quantity surveying profession. To promote the usage of 3D modelling which is far different compared to the traditional method, it is crucial to understand the constraints of 3D modelling and BIM. Therefore, this paper aims to compare the constraints of BIM and 3D Modelling in quantity surveying profession. Eleven semi-structure interviews have been conducted with the experienced quantity surveyors who are practising 3D modelling for quantities and cost estimation purposes to collect experts’ comments on the constraints of 3D modelling compared to BIM implementation. The content analysis which focuses on describing and quantifying phenomena is selected as a research analysis method for the diverse empirical data. The research finding indicated that technological constrains are significantly affecting the 3D modelling implementation while people and process constraints are less significant. This research finding serves as a guidance for quantity surveyors who are willing to take initiatives in implementing 3D modelling in quantity surveying profession.
