Current State of the Art Historic Building Information Modelling

Abstract

ABSTRACT:In an extensive review of existing literature a number of observations were made in relation to the current approaches for recording and modelling existing buildings and environments: Data collection and pre-processing techniques are becoming increasingly automated to allow for near real-time data capture and fast processing of this data for later modelling applications. Current BIM software is almost completely focused on new buildings and has very limited tools and pre-defined libraries for modelling existing and historic buildings. The development of reusable parametric library objects for existing and historic buildings supports modelling with high levels of detail while decreasing the modelling time. Mapping these parametric objects to survey data, however, is still a time-consuming task that requires further research. Promising developments have been made towards automatic object recognition and feature extraction from point clouds for as-built BIM. However, results are currently limited to simple and planar features. Further work is required for automatic accurate and reliable reconstruction of complex geometries from point cloud data. Procedural modelling can provide an automated solution for generating 3D geometries but lacks the detail and accuracy required for most asbuilt applications in AEC and heritage fields.

HBIM and Virtual Tools: A New Chance to Preserve Architectural Heritage

“…Their modeling is even harder with common software of modeling and requires a considerable amount of time. In fact, the criticism of the current research in this field is the loss of pre-defined libraries for modeling existing and historic buildings [5]. The key to realizing a model that strictly follows the project aim is to find a compromise between modeling and information.…”

Protocol to Manage Heritage-Building Interventions Using Heritage Building Information Modelling (HBIM)

“…HBIM has been defined as the recording and modelling of existing buildings, generating BIM geometry from point clouds [30]. Murphy has defined HBIM as a new system of modelling historic structures creating full 2D and 3D models, which include detail behind the surface of the objects concerning its methods of construction and material makeup [31].…”

“…Heritage BIM includes highly protected buildings that usually requires broader intervention projects and a careful life cycle management. Dore and Murphy [30] proposed six HBIM elements: heritage documentation standards, data collection techniques, 3D modelling concepts, as-built BIM and procedural modelling.…”

A Review of Heritage Building Information Modeling (H-BIM)

“…In addition, three different types stand out among the TLS systems: triangulation, phase difference, and Time of Flight (TOF). Each of these TLS systems are capable of producing point clouds of the objects; however, the accuracy and the density of the obtained point clouds will vary depending on the selected scanner type, as well as the number of scans made ( Figure 3) [36].…”
