Abstract

Building Information Models (BIMs) are becoming the official standard in the construction industry for encoding, reusing, and exchanging information about structural assets. Automatically generating such representations for existing assets stirs up the interest of various industrial, academic, and governmental parties, as it is expected to have a high economic impact. The purpose of this paper is to provide a general overview of the as-built modelling process, with focus on the geometric modelling side. Relevant works from the Computer Vision, Geometry Processing, and Civil Engineering communities are presented and compared in terms of their potential to lead to automatic as-built modelling.

9. Discussion

This paper gives an overview of the as-built modelling process, by presenting various research works from different research communities (Computer Vision, Geometry Processing, Civil Engineering) that are currently used, or have the potential of being used, for successfully solving the challenging task of automatic as-built BIM generation for infrastructure. Significant progress has been reported in the last years in this direction. While obtaining complete BIMs can engender high (unjustified) costs in practice, we believe that automatically generating working BIMs is achievable. For the future, the focus should be put on consolidating and integrating the existing techniques, along with developing new methods for object recognition. Joint research efforts within interdisciplinary projects can lead to accurate as-built BIM generation, producing a high impact in the construction industry.
