Geomatics techniques and building information model for historical buildings conservation and restoration

Abstract

Historical conservation and restoration is an important issue for heritage structures, this research aims to develop heritage building information model (HBIM) for Amman citadel in Jordan. In Jordanian Heritage Management, such models are still regarded a long way from becoming a well-established and widely used technique. Using terrestrial laser scanning technologies, the research will bridge the gap between historical documentation and historical building information modeling. HBIM was created with parametric pieces to reflect the study area's structural, functional, architectural, and historical aspects. The model also incorporates 3D geometry as well as non-geometric data like materials, appearance, and condition. This model also incorporates historical and architectural aspects, style and age. With a 1 cm spacing, the findings revealed that the utilized model could capture 425,000 points per minute with standard error of mean of 0.61 cm and standard deviation of 0.75 cm. It is recommended that a numerical reconstruction model of the citadel be created in order to check for any potential structural instability. In addition, it is suggested that a documentation effort be started to encompass Jordan's other significant historical and cultural sites.
