1. Introduction
Building Information Models (BIMs) are digital representations of facilities that encode all the relevant information about their life cycle from construction to demolition, including, but not limited to, 3D design drawings, schedule, material characteristics, costs, and safety specifications. Conceived using open standards1 to facilitate knowledge sharing and interoperability between different stakeholders, BIMs gained a general acceptance within the construction industry, as they are expected to provide significant cost savings and improved productivity in construction projects. Whilst creating as-designed BIMs (i.e. BIMs generated in the design stage of a facility) is a straightforward process becoming increasingly common, generating as-built BIMs (i.e. BIMs that reflect a facility in its as-built conditions) is a challenging, but necessary process for facilities not equipped with an as-designed BIM and for facilities where the asbuilt conditions differ from the as-designed BIM. The focus of this paper is set on the as-built BIM (AB BIM) generation, considering the cases when an as-designed BIM (AD BIM) is present or not. Creating an AB BIM requires two major steps: data collection, to capture the as-built conditions, and data modelling, to generate compact, but rich representations readily understandable by other processes. Although historically, (AD) BIMs were introduced in the 70’s, gaps in technology (in data collection and storage) and knowledge (in data modelling) prevented the construction industry from equipping facilities with AB BIMs; to this date very few AB BIMs exist. Auspiciously, the 3D reconstruction field, related to Computer Vision and/or 3D laser scanning techniques, filled the technology gap, offering off-the-shelf tools for generating 3D models of scenes. Consisting, basically, of a set of 3D points endowed with 3D Cartesian coordinates and possibly colour information, these models that will be denoted from now on as point clouds, are useful for visualisation or augmented reality purposes [90,91,1,94]. However, the data modelling side continues to be deficient, and the problem of converting the raw point cloud into a semantically rich BIM model is far from being settled. The commercial and academic tools available at this point to perform this conversion require extensive human intervention, making them expensive [23] and error-prone [68]. Given the expected economic impact, automatically generating AB BIMs from point clouds is a key objective for the industrial, academic, and governmental parties involved in the Architectural/Engineering/Construction and Facility Management industry (AEC/FM). This paper provides a general overview of the as-built modelling process, with focus on the data modelling side, and presents relevant works from different research communities, discussing their potential of being used to automatically generate AB BIMs.
