Building technology study of the revitalization of the Governor's Palace in Brno
Osladil, Martin ; Doubek, Rostislav (referee) ; Kantová, Radka (advisor)
The content of the bachelor's thesis is a construction-technology study of the revitalization of the Governor's Palace in Brno. It focuses on the main stage processes of the implementation of the repair of plasters, floors and paved area in the historically protected zone of the city of Brno. In this thesis, the traffic situation is addressed in detail with the design of routes from individual collection points and landfills to construction sites. There is also a technological study of the implementation of the main technological stages. Repairs of plasters in the exterior and interior of the building and all newly designed compositions of floor structures and reinforced surfaces with cutting works as well as making new constellations are dealt with. Based on the design documentation, I have produced a detailed statement of the acreage for all areas and the annex where the areas concerned are indicated. For both stage processes, a time and financial plan is developed using software that is an annex to the work, accompanied by a comment ary in the text section. The basic cockpit of construction traffic is also addressed with a proposal for the distribution of areas and resources for construction. For stage processes, there are 2 technological regulations in which there is a detailed procedure for all compositions and types of processes. In the chapter "Design of machinery assemblies" there is an assessment of the possible deployment of machinery with a focus on both economic and technological advantage. The work also deals in detail with safety measures at the construction site, with an emphasis on possible risks and the design of measures in the implementation of the main stage processes and behaviour at the construction site. In addition, details of the structures, continuities and protection of the monument-worthy structures are processed. This object is very special due to the preserved elements of Baroque architecture, and therefore the design of the solution is directed towards the highest level of preservation and preservation of the monument.

Restoration of the renaissance town hall in Hostěradice
Tulis, Zdeněk ; Muroň, Ivo (referee) ; Ležatka, Lukáš (advisor)
The aim of the bachelor thesis was to prepare project documentation for building permits and construction implementation based on an architectural study, which was created within the course BGA036 - Atelier of Monuments Restoration. The subject of the study was the restoration of the listed Renaissance town hall in Hostěradice, which had lost its original purpose as an administrative building and is now waiting for a new use. The bachelor's thesis of the restoration of the town hall in Hostěradice is based on the requirements of the building owner, the analyses carried out on the site and the spatial limits that the building and the area under consideration allow. Based on this input, a concept is developed that combines historical and modern building layers into a coherent solution and brings new cultural and social life to the building. The use of the Town Hall premises are designed with the size and needs of the community in mind. The proposed spaces are multifunctional and will allow for a variety of indoor and outdoor cultural events. Commercially rentable studios and service spaces including sanitary facilities are also part of the solution. The bachelor's thesis also includes a focus on the urban context of the town hall, improving the building's structural and technical performance and achieving a unified expression of the building using modern elements. The town hall aims to become a cultural centre of the village that retains its historical value.

Preventive Restructuring as Protection against Bankruptcy
DERMEKOVÁ, Petra
The topic of this thesis is the issue of preventive restructuring as protection against bankruptcy. It is a new and topical topic that solves the unfavourable economic situation of businesses and entrepreneurs in a different way than the insolvency law stipulates. Preventive restructuring has become part of the Czech legislative environment in response to the requirements of the European Union. The newly adopted law gives entrepreneurs the opportunity to restructure their companies in a timely and effective manner and thus avoid resolving their debt situation through bankruptcy. The thesis is focused on assessing whether there is any real hope in limiting or reducing the number of undesirable liquidations of viable businesses and enterprises due to this new aspect of Czech legal and economic life, as well as to evaluate the substance of business restructuring in comparison with the rules of insolvency law as a solution for negative economic situations of businesses.

Experimental testing of hydroinsulating injection screens efficiency in dependance on properties of building materials
Červenka, Martin ; Černý, Vít (referee) ; Drochytka, Rostislav (advisor)
The most of the buildings are almost always faced with moisture in our climate. In the past, the humidity was reduced and conducted only by mechanical methods. Over time, chemical wet masonry method also known as chemical infusion curtain was invented and introduced into practice. This method involves the creation of boreholes at a selected height of humid masonry. These boreholes are impregnated with special solutions. These solutions in humid masonry fill pores in the field of boreholes and thanks to this subsequence the monolithic waterproofing curtain is created. The objective of this work is to determine the methodology for verifying effectiveness of various types of waterproofing injection curtains depending on the properties of the various types of building materials.

Strengthening of vaulted structures by prestressing
Požár, Michal ; Solař,, Jaroslav (referee) ; Drahorád,, Michal (referee) ; Klusáček, Ladislav (advisor)
The topic of this Ph.D. theis is repairing and strengthening of historical wagon vaults (barrel vaults, tunnel vaults) using post tensioning with tendons (monostrands) in longitudinal direction. The vaults should be without an edge, that´s mean the baroque vaults are well appropriate for this method. The pointed barrel vault should be problematic. The stabilization is for a wagon vault created by semicircle or segment part of a circle as well as an elliptic shape. The study has been made for vault with a width of 1 m and for the prestressing force has been used one tendon only. Of course, this method could be apply for normal constructions with a width of many meters. In this case, more tendons should be use with a suitable spacing. The goal of this work was to monitor an experiment model of an wagon vault and a real strengthened baroque vault of a church in Švábenice. During the monitor time, the static Analysis has been made. For these analysis appropriate finite elements in Ansys program has been use. The results of this work is to amplify the knowledge of the real behaviour of strengthened vaults, which could be use like instruction for the civil engineers. Further the public information guide to build an appropriate model of an Vault with an interaction with post-tensioning tendons.

Remediation of former In-Situ uranium mining region.
Kříž, Jakub ; Kalous, Jaroslav (referee) ; Jícha, Jaroslav (advisor)
Remediation process of region, formally exploited for chemical leaching of uranium, is based on pumping water contaminated mostly by residuals of sulfuric acid from the relevant geological horizons. The contaminated water is then treated in a chemical plant. In the treatment process evaporators play the key role. Presently operating evaporators – three units – are of falling film type. Heating service is provided by compressed vapor that is generated by evaporators. For driving the compressors and associated circulating pumps of each unit electric power of 3,4 MW is required. In the evaporators treated solution is distributed into individual tubes by nozzles of cyclone type that are mounted at the top end of tubes. In the evaporators feed solution contains calcium sulfide of low concentration. Once the calcium sulfide concentration in the evaporating process reaches the state of saturation, even locally, fouling is initiated. Thus the solids start to grow on the inner surface of the tube wall and the nozzle’s openings become restricted. The evaporator performance – evaporating rate – gradually declines and when it reaches the bottom limit the evaporator has to be shut down. This is followed by carrying out the cleaning procedure. At the time when the evaporators started operating (1996) the period between shut downs lasted around a half a year. However, gradually, this period has become substantially shorter – presently it may even last one week only. The thesis proposes two ways of approaching the present hardly acceptable state. First, replacement of distributing nozzles by a set of properly perforated sieve trays secures the uniform distribution of solution into each individual tube. Second, evaporators’ duty will be taken over by newly build multi-flash concentrator that will substitute the presently operating evaporators. Configuration of this new equipment is derived from widely used multi-flash distillation of sea water. Heat required by the concentrator’s end heaters is drawn from a gas turbine exhaust gas. Steam provided by Heat Recovery Steam Generator is supplied to the condensing heat exchangers installed on the evaporator’s feed stream. Generator coupled to the gas turbine, fueled by natural gas, provides the electric power of 30 MW for export.
