| summary |
There is a great need for holistic documentation and management of heritage buildings using Historic Building Information Modelling (HBIM) frameworks. Limitations can be found in current literature regarding the accuracy, the level-of-detail, and the required attributes of final HBIM models, especially in cases where digital information intents to be used for the documentation of heritage timber roof structures. Previous research works indicate that geometry is created by the extrusion of the cross sections of the beams, and the usage of existing 2D drawings leading to simplified geometries in HBIM. This results in an absence of critical information, for example the bending of the wood, and its pathology. In this study, a novel Scan-to-HBIM methodology is exemplified and applied in heritage timber roof structures, which includes the implementation of recent remote sensing technologies for capturing the as-built data, with high levels of accuracy both in geometry as well as in pathology. In terms of geometry, algorithmic processes are used, that integrate parametric and BIM environments for the automatic creation of timber roof frames from point cloud data, which are adjustable to the abnormalities found in heritage buildings. As regards to pathology, high-resolution textured mesh models are created from photogrammetric procedures, which indicate in detail any possible defects to the existing timber elements. Detailed geometry and pathology are further analyzed, and a BIM database is created for documenting the typology, materiality, and level of damage to timber components. The methodology is tested on a Franko-Byzantine Timber roof Church in Cyprus, which includes a complex timber structural system. |
