“…If you want to get good results, you need to make sure that the candidate damage patterns of the building in the database is plenty (some parameters must be set carefully enough). Ma et al [66] proposed an approach to edit asdamaged BIM models and presented a laser scanning emulator to generate point cloud that is similar to a real laser scanning on site according to aforementioned models. The accurate data from synthesizing technology fills the hole in the scarcity of data from buildings that have suffered real earthquake damage.…”

The integration of building information model (BIM) with point cloud from 3D laser scanner provides powerful assistance in a variety of applications in the life cycle of building. However, the adoption of BIM and 3D laser scanning for applications in the whole life cycle of buildings has yet to be satisfactorily reviewed. There is a need to understand the current situation of applications with BIM and 3D laser scanning and their combined methods. The authors summarized combined methods of BIM and 3D laser scanning at first. Then the work presented in this paper provides summarization of applications in the life cycle of building. In addition, the impact of emerging technologies on applications also be discussed. In this review, articles were limited to those published over the last decade. Two patterns in the approach to integrate BIM and 3D laser scanning are reviewed. Several domains of application namely construction progress tracking, building components quality control, construction site safety, structural health monitoring, rescue after the disaster, energy modeling and management and modeling for exist building are looked back. According to occurred time of these applications, this paper divides them into two classes: applications in construction period and applications in maintenance period. Based on the observed limitations in the reviewed papers, the authors conclude some potential future research trend for these applications based emerging technology at the same time.

The problem of managing existing structures before and after seismic events has led to the development of many different strategies across the globe. These aim to mitigate the catastrophic effects of earthquakes on the occupants of a building, as well as improve the management of the emergency that inevitably ensues. This paper explores the use of an openBIM approach to resolve the issues referred to above, which is possible because of two new standards: Industry Foundation Classes and Information Delivery Manuals. A review of the most popular strategies adopted in both the pre- and post-earthquake phases is conducted using a process map. This organizes the relevant steps and processes into tasks, and additionally identifies the points at which information is produced and exchanged and the party responsible for doing so. Also described is how BIM models can be utilized in essential pre- and post-earthquake activities, as well as current benefits and ongoing developments intended to improve the processes themselves.

“…The first building sustained moderate damaged and the second sustained heavy damage including a soft story collapse of its first floor. The inputs for the procedure, including the full 'as-built' BIM models and synthetic point clouds of the damaged buildings, were prepared using the methods and software detailed in Ma et al [44]. The outputs are BIM models of the as-damaged state of each building in IFC format.…”

“…Thus, this model served two purposes: it represents the ground truth for the experiment and it is the source data for scanning, since no laser scans of the real damaged building were available. Details of the procedure for preparing the synthetic data is provided in Ma et al [44].…”

After an earthquake, Terrestrial Laser Scanning (TLS) can capture point clouds of the damaged state of building facades rapidly, remotely and accurately. A long-term research effort aims to develop applications that can reconstruct 'as-damaged' BIM models of reinforced concrete (RC) framed buildings based on their 'as-built' BIM models and scans of their 'as-damaged' states. This paper focuses on a crucial step: generating an initial 'best-guess' for the new locations of the façade structural members. The output serves as the seed for a recursive process in which the location and damage to each object is refined in turn. Locating the 'as-built' structural members in the 'as-damaged' scan is challenging because each member may have different displacement and damage. An algorithm was developed and tested for the case of reinforced concrete frames with masonry infill walls. It exploits the topology of the frames to map the original structural grid onto the damaged façade. The tests used synthetic datasets prepared from records of two earthquake-damaged buildings. In both cases, the results were sufficiently accurate to allow progress to the following step, assessment of the individual structural members.
