Development of BIM model fitness review system for modelling quality control

Abstract

The increasing focus on Building Information Modeling (BIM) enables massive utilization of model checking software. Several software applications, such as Solibri and Navisworks, are applicable with a large list of powerful functions. Existing computer-supported model checking applications are mainly concentrated on verifying various codes and constructability based on as-designed 3D model which derived from 3D design results or 2D drawings. The effectiveness of these kinds of model check largely relies on the accuracy of the as-designed 3D model itself. Unfortunately, rare research is implemented to review the as-designed 3D model and assure information accuracy. This paper develops a systematic approach for BIM model fitness review through predefined standards. Firstly, the paper starts by discussing the need for automated BIM model review and analysing the limitations of existing model checking efforts in this regard. Then, an overview of the proposed BIM Model Fitness Review System (BIM<sup>2</sup>FRS) is provided. Thirdly, the paper presents a case study to validate the BIM<sup>2</sup>FRS. The result shows that: (1) the system can efficiently assess BIM model fitness and support BIM model management; (2) the development of the ABIM<sup>2</sup>R system is still very young; and (3) only limited types of model fitness review are presented.
