Analiza przyczyn niszczenia kamienia w elewacjach kamiennych wentylowanych i możliwość działań zapobiegawczych na przykładzie wybranych obiektów Krakowa
(Data obrony: 2012-09-28) Kolankowski, Mateusz
Wydział Geologii, Geofizyki i Ochrony Środowiska
The aim of this study was to investigate the causes and symptoms of destruction of stone ventilated facades. 13 buildings in Krakow have been selected to determine to what extent this destruction can be prevented. Sandstones from 5 Polish deposits have been used to cover these 13 buildings. Certain factors and evidence of damage have been identified. The following tests have been performed: petrographic characteristics, water absorption, resistance to forces pulling out construction dowels and fracture toughness. Then, after application of hydrofobization, water absorption was checked once more. Later, the impregnate was used and the resistance to forces pulling out construction dowels and fracture toughness were evaluated. The final conclusion is as follows – the types of damages are correlated with the properties of stone, and that the hydrofobization and impregnation can reduce the rate of the façade destruction.

Buildings and dwellings of Krakow in the 16th-17th century - descriptions contained in the city deeds
(Wydawnictwa AGH, 2014) Follprecht, Kamila
»Wiertelnicy« – those were City officers appointed by the City Council to oversee the construction industry in the old Krakow. Preserved in the state Archives are the City books of records that contain minutes and rapports regarding the activities of the »Wiertelnics« – often referred to as the »construction police« or as it probably would be more adequate the old-time city engineers. The »wiertelnics« conducted site reviews. The preserved documentation of their activities such as divisions and subdivisions of real property; preformed estimates of value of real property; damage assessment (particularly, as it was pertaining to border or division walls, and prescription of construction works that were necessary to ensure building and construction safety constitutes an very important source of historic documentation in regard to city engineering as it allows to follow not only the history of the physical constructions of buildings and dwellings themselves, but also the technology and technical solutions i.e. plumbing or other necessary adaptations needed by particular workshops or craftsmen’s sites. It can be observed that some solutions that were used by the owners of the buildings were frequently cost driven and consequently of a very provisory nature. Later on, much greater investments were necessary to avoid imminent »construction catastrophes«. The information contained in the City public records of the »Wiertelnic’s Deeds« give also some insights that are not directly related to the construction requirements or activities themselves, but were the predominant factors that determined the physical shape of the building or a site.

Verification of the geometrical representation of buildings in cadastre using UAV photogrammetry
(Wydawnictwa AGH, 2021) Karabin, Marcin; Bakuła, Krzysztof; Łuczyński, Robert
The aim of this study was to determine the potential benefits of using UAV-based data to verify the accuracy of the geometry of the outlines of buildings registered in a cadastral database, and to investigate the potential use of data from UAV platforms in measuring the buildings. The authors examined whether the acquisition of data from UAVs can replace field measurements or only support them. The advantages and disadvantages of such data acquisition methods, compared with more well-established measurement methods, were identified.
