VDI/WTA 3817 Blatt 2:2021-08 - Draft

This standard is part of the revised and significantly expanded version of the standard VDI 3817 from February 2010 to the new series of standards VDI/WTA 3817. The series of standards provides users with practical working documents, decision-making aids, assessment and evaluation criteria as well as checklists for procedures appropriate to listed buildings when carrying out construction work in listed buildings and buildings worthy of preservation. This series of standards provides comprehensive recommendations for professional action in terms of monument preservation and construction technology and, at the same time, advice on how to avoid construction defects, planning errors or other mistakes. VDI/TWA 3817 Part 1 contains the monument preservation principles. It is therefore indispensable for the application of this standard. This standard highlights the problem areas that arise as a result of structural measures for the repair or modernization of listed buildings. These problems can be found in static issues as well as in aspects of building physics (indoor climate, heat, moisture and sound insulation) or requirements for accessibility and fire protection, if today´s user requirements are applied without taking into account the individual circumstances of historic preservation. In addition to the change in appearance, there is often also the risk of loss of substance of building materials or components.
