The three volumes of the work for architects and construction engineers in renovation and heritage preservation focus on building constructions from the period between 1860 and 1960. Elaborate image panels present essential construction details in the form they were executed according to the building regulations and the recognized rules of architecture at that time. Knowledge of the construction methods and accepted construction rules of that era is a prerequisite for proper work on historic buildings. The three volumes include detailed evaluations of the previously valid building codes and regulations, constructive details, and approaches to dimensioning and proof of load-bearing capacity. The Beuth Media Library provides the respective historical building regulations in their original text.
