TL;DR: Results show scarce BIM implementation in existing buildings yet, due to challenges of (1) high modeling/conversion effort from captured building data into semantic BIM objects, (2) updating of information in BIM and (3) handling of uncertain data, objects and relations in B IM occurring inexisting buildings.

TL;DR: A survey of state-of-the-art methods for automated as-built BIM creation can be found in this article, where the main methods used by these algorithms for representing knowledge about shape, identity, and relationships.
Abstract: Building information models (BIMs) are maturing as a new paradigm for storing and exchanging knowledge about a facility. BIMs constructed from a CAD model do not generally capture details of a facility as it was actually built. Laser scanners can be used to capture dense 3D measurements of a facility's as-built condition and the resulting point cloud can be manually processed to create an as-built BIM — a time-consuming, subjective, and error-prone process that could benefit significantly from automation. This article surveys techniques developed in civil engineering and computer science that can be utilized to automate the process of creating as-built BIMs. We sub-divide the overall process into three core operations: geometric modeling, object recognition, and object relationship modeling. We survey the state-of-the-art methods for each operation and discuss their potential application to automated as-built BIM creation. We also outline the main methods used by these algorithms for representing knowledge about shape, identity, and relationships. In addition, we formalize the possible variations of the overall as-built BIM creation problem and outline performance evaluation measures for comparing as-built BIM creation algorithms and tracking progress of the field. Finally, we identify and discuss technology gaps that need to be addressed in future research.

TL;DR: The proposed TLS method allows measurement of the entire bridge's deformed shape, and thus a realistic solution for monitoring structures at both structure and member level, and can be used to create a 3-D finite element model of a structural member or the entire structure at any point in time automatically.
Abstract: This paper presents a new approach for the health monitoring of structures using terrestrial laser scanning (TLS). 3-D coordinates of a target structure acquired using TLS can have maximum errors of about 10 mm, insufficient for health monitoring of structures. A displacement measurement model to improve the accuracy of the measurement is offered. The model is tested experimentally on a simply supported steel beam. Measurements were made using 3 different techniques: 1) linear variable displacement transducers (LVDTs), 2) electric strain gages, and 3) a long gage fiber optic sensor. The maximum deflections estimated by the TLS model are less than 1 mm and within 1.6% of those measured directly by LVDT. Although GPS methods allow measurement of displacements only at the GPS receiver antenna location, the proposed TLS method allows measurement of the entire bridge's deformed shape, and thus a realistic solution for monitoring structures at both structure and member level. Furthermore, it can be used to create a 3-D finite element model of a structural member or the entire structure at any point in time automatically. Through periodic measurement of deformations of a structure/structural member and performing inverse structural analyses with measured 3-D displacements, a structure's health can be monitored continuously.
