Phased Reverse Engineering Framework for Sustainable Cultural Heritage Archives Using Laser Scanning and BIM: The Case of the Hwanggungwoo (Seoul, Korea)

Abstract

This study proposed a phased reverse engineering framework to construct cultural heritage archives using laser scanning and a building information model (BIM). This framework includes acquisition of point cloud data through laser scanning. Unlike previous studies, in this study, a standard for authoring BIM data was established through comparative analysis of existing archives and point cloud data, and a method of building valuable BIM data as an information model was proposed. From a short-term perspective, additional archives such as member lists and drawings can be extracted from BIM data built as an information model. In addition, from a long-term perspective, a scenario for using the cultural heritage archive consisting of historical records, point cloud data, and BIM data was presented. These scenarios were verified through a case study. In particular, through the BIM data building and management method, relatively very light BIM data (499 MB) could be built based on point cloud data (more than 917 MB), which is a large amount of data.

Study on Representative Parameters of Reverse Engineering for Maintenance of Ballasted Tracks

“…Scanning using a 3D laser scanner for allows rapid work without contacting objects and facilitates the generation of a 3D model with a smooth surface [2,3]. RE was developed based on the advantages offered by a 3D scanner and can output to Scan-to-CAD or Scanto-BIM.…”

“…Furthermore, they applied the manual steps of acquisition of point cloud data, segmentation of material properties, and the construction of a BIM model to the process. Ham et al [2] proposed the automated registration method of point cloud data by 3D scanning of complex cultural heritages and extracted a CAD file (*.dwg). They also proposed the phased RE framework for generation a BIM model using the AUTODESK Revit software by extracting the IFC (Industry Foundation Classes) library from a geometric model.…”

“…With recent developments in digital technology, including research on reverse engineering (RE), studies on constructing building information models (BIM) by acquiring as-built structure shape information through three-dimensional (3D) scanning [1]. RE is a technology used to generate drawings of old buildings for which no drawings are available [2] or to acquire shape information about objects and extract 3D models and two-dimensional (2Dloe) drawings using photogrammetry and light detection and ranging (LiDAR) techniques for reviewing the construction of structures [3]. RE using a 3D laser scanner is faster than the conventional method and has the advantage of acquiring information in a noncontact manner [4].…”

“…(1) the representative parameters for the rail, ballast, and sleeper ware identified whether the shape of the ballasted track could be detected. (2) The representative parameters for the rail, ballast, and sleeper ware identified whether the ballasted track damage types described in the literature review could be examined. Finally, based on the testbed results, the shape types of objects that could be distinguished by the representative parameters and the ballasted track damage types that require maintenance were summarized.…”

A Survey of Applications With Combined BIM and 3D Laser Scanning in the Life Cycle of Buildings

“…Manual process with software is conducted subsequently. Manual modeling method is adopted frequently for heritage buildings [35]- [37], which consist of heterogeneous, complex, and irregular components. There are currently no automatic software processes for the parametric design of the heritage buildings components.…”
