Authentication of real rock mass field voltage to increase safety in anomalous stress states
Koníček, Petr ; Staš, Lubomír ; Ptáček, Jiří ; Kaláb, Tomáš ; Chura, Jan ; Souček, Kamil ; Waclawik, Petr
Voltage fields are one of the key factors that, decisively, along with the mechanical and remodeling properties of rocks, greatly influence the behavior of the mountain massif. Knowledge of stress fields is beneficial for the design and successful implementation of geotechnical underground projects (eg for the assessment of the stability of underground spaces, the behavior of proposed reinforcements of underground structures, for space-time placement of underground structures) especially in non-trivial geomechanical conditions, both in terms of natural factors affecting stress fields structural and geological structure of the rock mass, tectonic stress, cracks and discontinuity in the rock mass) as well as anthropogenic factors (geomechanical configuration of the underground spaces and dynamics of their changes). Geotechnical practice in our (Czech) conditions is usually used only calculations of a voltage field based primarily on the theoretical behavior of the rocks and the assumed vertical geostatic pressure at a given depth. The development of possible progressive deformations of the stress field is then derived from the development of anthropogenic interventions into a relatively homogeneous massif. In fact, tension is also affected by close geological structures. The data obtained from the study of the magnitude, direction and change of stress in the mountain massif are a significant contribution in mathematical modeling where they can be used as input parameters to obtain a more accurate picture of the behavior of mountain massifs and underground structures in the subject areas.

Bukov Underground Research Facility (Bukov URF) has been built as a test site to assess the properties and behaviour of the rock mass analogous to selected candidate sites. It is situated at a depth corresponding to the proposed storage depth of the final locality for the Czech Republic´s deep repository of high-level radioactive waste. Bukov URF is located in the Vysočina Region, the cadastral district of Bukov, approx. 3 km south-eastwards from the municipality of Dolní Rožínka. The underground research facility is placed approx. 300 m from the Bukov-1 shaft, namely on the level 12 of the shaft, at the depth of about 550 – 600 meters below the Earth’s surface. As for the regional geology, Bukov URF is found at the southern part of the Rožná uranium deposit, at the north-eastern edge of the Strážek Moldanubicum close to its contact with the Svratka Unit. The rock mass is composed of a relatively monotonous sequence of differently migmatized biotite gneisses to stromatic migmatites, continuing with amphibole-biotite to biotite-amphibole gneisses and amphiboles, with occasional fine intercalations of aplites, pegmatites or calc-silicate rocks (erlanes). Between 2013 and 2017 and within the complex geotechnical characterization of the Bukov URF, the Institute of Geonics of the Czech Academy of Sciences (Ústav geoniky AV ČR, v.v.i.) in Ostrava carried out a series of laboratory and field works in order to provide a detailed description of the geotechnical and geomechanical properties and quality of the rock mass. The works included the determination and assessment of the physical-mechanical properties of the rocks sampled from the walls, boreholes and ground surface in the locality, the determination of stress state and deformation properties of the rock mass using the methods of hydrofracturing of borehole walls, Goodman Jack and CCBO, or CCBM, determination of the rock mass quality based on selected index geomechanical properties, periodic, long-term strain-gauge measurements and convergence measurements, and the assessment of the effect of technical and mine-induced seismicity on the rock mass of interest. The implemented set of research works was supposed to render a sufficient and integral whole of geotechnical and geomechanical knowledge vital for the subsequent implementation of extensive research experiments focused on long-term safety and technical feasibility of the future national deep repository of radioactive waste.

Land ownership restrictions
Kaláb, Tomáš ; Drobník, Jaroslav (advisor) ; Franková, Martina (referee)
This paper disserts land ownership restrictions. Land ownership is restricted more intensively than other kinds of ownership due to the specificity of land as its object. Land ownership restrictions can arise either under law, under administative decisions, or under contracts. The restrictions are always represented by obligations either to allow, to omit, or to do something. The existence of land ownership restrictions is directly related to the level of social development. That is why land ownership restrictions can be found in very ancient documents such as the Code of Hammurabi. This paper, however, mainly focuses on various land ownership restrictions contained in the Charter of fundamental rights and freedoms, in legislation on nature protection, the forest act, lagislation on agricultural land resources protection, water management regulations, building code, legislation on land consolidation, law on roads and in legislation on neighborly relations. In the end the dissertation analyzes the land ownership restrictions arising from rights to property of another and from contracts with inter partes obligations.

Offer of the Construction Company to Public Tender
Svobodová, Lenka ; Kaláb, Tomáš (referee) ; Nováková, Jana (advisor)
The diploma thesis describes a process of public tender for building contracts from a construction company’s perspective. The theoretical part introduces the basic concepts and procedures encountered during issuance, awarding and completion of public tenders. The necessary procurement rules and guidelines are also included. The practical part defines an actual tender offer from a particular contractor. The tender in question is a construction of leisure centre in Ratiskovice.
Construction contract in Germany
Vitásek, Stanislav ; Kaláb, Tomáš (referee) ; Marková, Leonora (advisor)
This work deals with the bid price for a development project base on the construction of houses funded by a private German investor. The bid price create with help of budget in a various structures. The various structures of the budget, which use in German environment usually. Specifically, it uses the norm DIN 276 and classification StLB includes software. The main target of my diploma thesis is suggestion for create the bid price. The suggestion with choose form and manner of valuation build works, which respect all legislation for realization construction in Germany.
Management of Development Projects
Lněnička, Martin ; Kaláb, Tomáš (referee) ; Waldhans, Miloš (advisor)
The thesis analyses a development project of 21 houses in the village of Podolí u Brna, which was carried out by Kaláb – stavební firma, spol. s r.o. It provides a description of the company structure and focuses on some of their processes, such as risk analysis, investment decisions in the pre-investment project phase, project funding, planning, and time management based on time schedules. The text also takes a close look at all the steps that were taken during the implementation of the Podolí project, and zooms in on regular on-site records monitoring how much work has been actually done. Furthermore, the thesis brings an analysis of the current developer market in Brno, focusing in particular on latest developments in logistics, and office & residential construction. And last but not least, the thesis also observes how prices in the real estate market have developed over the last decade and how new residential units in the Czech Republic have been lately built.
