“…Ground Penetrating Radar (GPR) is an established non-destructive technique (Binda et al 1998, Binda et al 2000, Moropoulou & Labropoulos 2015, which exploits the wave character of electromagnetic fields and is based on the propagation and analysis of electromagnetic radiation to image the examined structure. The ground penetrating radar system used in this survey was a MALÅ Geoscience ProEx system with 1.6GHz and 2.3GHz antennae.…”

ABSTRACT:An interdisciplinary team from the National Technical University of Athens is performing the restoration of the Holy Aedicule, which covers the Tomb of Christ within the Church of the Holy Sepulchre in Jerusalem. The first important task was to geometrically document the monument for the production of the necessary base material on which the structural and material prospection studies would be based. One task of this action was to assess the structural behavior of this edifice in order to support subsequent works. It was imperative that the internal composition of the construction be documented as reliably as possible. To this end several data acquisition techniques were employed, among them ground penetrating radar. Interpretation of these measurements revealed the position of the rock, remnants of the initial cave of the burial of Christ. This paper reports on the methodology employed to construct the 3D model of the rock and introduce it into the 3D model of the whole building, thus enhancing the information about the structure. The conversion of the radargrams to horizontal sections of the rock is explained and the construction of the 3D model and its insertion into the 3D model of the Holy Aedicule is described.

“…It is therefore important experience and curiosity of people performing an inventory of damages in such buildings. In the cases of difficulties in access to damage modern technologies can be useful, for example: digital photogrammetry, 3D scanning [13] or increasingly popular thermography [14,15].…”

Abstract. Historic buildings in Poland are largely neglected objects that small percentage is preserved in its original form. Unrelenting in the case of historic buildings is a time that brings with it the natural processes of aging of buildings , but also the history of the object which is often marked by military conflicts, fires or even incompetently carried out reconstruction. Nowadays historic buildings are also destroyed by the rapid development of infrastructure and residential construction. This development could lead to changes of water in the soil, make changes in the geologic al structure or cause exposure of the historic building to the new influences (eg. traffic vibrations), to which building has not been subjected so far. Vibrations are often omitted in environmental issues, although the protection against noise and vibration has its place in the Law on Environmental Protection. This article presents the methodology for the measurement and interpretation of vibration influence on historic buildings and the assessment methods of technical condition of historic building on the example of dynamic measurements made on St. Nicholas Church in Krakow. The importance of well-done crack-by-crack documentation and characterization of damages based on damage index is shown. Difficulties that can be encountered when determining the causes of technical condition of historic buildings are also shown. Based on the example of the Church in the article are also given the possible protection solutions of historic structures from vibrations.

“…These are complex inspections that may involve non-negligible costs, such as radiography, thermography and infrared photography, ultra-sound, magnetometer, and endoscopic measurements. Some of these techniques have some drawbacks, such as the need for the equipment to be handled by professionals with much experience, and the complex nature of interpretation of the results ( Binda et al ., 2000 ;Santos et al ., 2003 ;Magalh ã es et al ., 2005 ).…”
