Abstract

This work deals with the different methods of building surveys. Special attention is paid to the record of building geometry. But methods of investigation of building materials are also considered. First, the classic approach to surveying buildings is presented to the readers. Proven measurement techniques are explained on the basis of sketches; the instruments used in this case are presented with color images. In the later chapters of this work, the reader is introduced to modern building survey systems. The use of a standard computer allows numerical evaluations of photos and makes the interpolation between two points in space measured in situ possible in the office. The monitoring of onsite measurements and the (also associated) reduced personnel costs by using site-ruggedized laptops are also discussed. But especially, the mystical world of photogrammetry is entered. The mathematical background is explained for the most part and software developed at IMB shows how to master façade evaluations using a photo and everyday programming means (the source code is located in Appendix C). Investigation processes of building materials and the fledgling recording system “laser pantograph” complete the circle of modern building acquisition systems. The use of computers causes in every area of daily life an automatic increase in information density. This fact is taken into account by modeling considerations in the last section.
