Renovation of 16th Century Salt House Roof (Lubań, Lower Silesia, Poland) – Case Study

Abstract

This article presents next step of the restoration works in the Salt House in Lubań, Lower Silesia, Poland. The first stage of technical and conservatory problems which appeared during the restoration process was described in the article “Between conservators theory and modern construction’s codes. Renovation of roof of 16th century Salt House in Lubań, Lower Silesia, Poland”, which was presented on 5th International Conference on Structural Health Assessment of Timber Structures, 25-27 September 2019, Guimarães, Portugal [1].

The Salt House in Lubań, Lower Silesia, Poland was erected between 1537 and 1539. This historic building is located between medieval defense walls, and it was used as a storage house for salt and grain until the end of the 18th century.

The technical documentation was prepared in 2016, which included 3-D scans of roof truss repair, as well as technical codes and restoration works. During the first phase of the works, the author of this article, who is also a Supervising Engineer, and an expert of the Ministry of Culture and National Heritage Republic of Poland, discovered a lot of discrepancies between the technical documentation and reality. The differences as well as the attempts to adjust restoration works and the technology of works were widely presented in an article at the SHATiS’19, Portugal.

The authors of this article want to show the problems that appeared during the continuation of renovation works and their solutions with reference to historic timber and masonry structures.
