Survey and Diagnostics of Building Construction
Bernard, Lukáš ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
This thesis deals with a diagnostic survey of a reinforced concrete frame. The first part of the thesis focuses on the properties of the reinforced concrete as well as on the detection of the reinforced concrete’s properties using selected non-destructive methods, semi-destructive methods and destructive methods. The second part of the thesis, which is closely related to the first part, focuses on detection of piles’ and beams’ reinforcement using an electromagnetic indicator Profometer PM-630, Ground-penetrating radar Hilti PS 1000 and chopped probes. It also focuses on determining the compressive strength of the concrete using the ultrasonic impulse method of the Pundit PL-200 machine. The results are further specified by the cores description.
Survey of the facial sandstone masonry of the stone coat of historic structures with the use of non-invasive analytical techniques of ground-penetrating radar
Havlín, J. ; Slavíková, M. ; Gláser, Petr ; Válek, Jan ; Pavelka, K. ; Panošová Hucková, M.
This conservation procedure includes a description of basic steps, which must be followed to use the ground-penetrating radar and to gain useful data for composition visualization of facial sandstone masonry used in historic structures. Suitable settings of the GPR device are introduced for collecting data and the way of their processing with the aid of software. The conservation procedure applies a non-invasive analytical technique of GPR when surveying stone structures and therefore it can be a useful specifying tool of particular details during the execution phase of the construction-historical survey

Methodology of the use of non-invasive surveying methods - ground-penetrating radar, impact-echo method and ultrasonic transmission measurement of the surface to assess the condition and construction details of the sandstone coat of buildings
Havlín, J. ; Slavíková, M. ; Válek, Jan ; Pavelka, K.
The methodology describes principles of selected methods (ground-penetrating radar, impact-echo method, ultrasound), their potentials, limitations and advantages when combined during the survey of stone coats of structures. Further on, the methodology indicates the process of the measurement itself and evaluation of the collected data.
