"3D Laser Measurement as Part of an Integrative Building Survey for the Recording of Built Heritage";
Talk: 17th International Conference on Cultural Heritage and New Technologies, Wien (invited); 11-05-2012 - 11-07-2012.

The process of building archaeology is a complex interaction of various research and surveying methods for the holistic analysis of a building in an interdisciplinary approach. For a contemporary building survey, the knowledge of different survey methods reaching from the classical hand measurement to tachometry, photogrammetry and the high tech method of 3D laser scanning is inevitable. Only the combination of different survey methods enables a flexible and efficient work on site, which is an ongoing process and has to be adapted by object.
As a tradition, at the Department of History of Architecture and Building Archaeology at the Vienna University of Technology interdisciplinary methods for building survey are applied and refined continuously. Nowadays within many projects of different scales, various ways of acquisition and usage of 3D scan data for architectural structures in the frame of building archaeology analysis were developed. The examples range from construction parts like domes and vaults to single buildings to urban structures. Latest projects in Austria, Neusiedl am See (topochronological analysis of baroque cellars), Tarragona, Spain (survey of the dome of a roman villa from a lifting platform), in the theater of Ephesus, Turkey (building archaeology of the entire existing structure of the auditorium), in the historic city center of Jeddah, Saudi Arabia (building survey and documentation of traditional urban architecture as base for restoration work) show the manifold fields of application of this successfully proven approach. The paper explains the role of 3D laser scan raw data as starting point for detailed architectural plans, sections and views, volume studies as well as further documentation material like catalogues and mappings.
