Building Construction Project - Implementation of Highway Overpass no. D1 - 150
Nováková, Martina ; Novotný, Michal (referee) ; Nečasová, Barbora (advisor)
This diploma thesis deals with demolition of the motorway overpass. The bridge (overpass) is located over the D1 motorway from Prag to Brno at the 115,881 km. On the brigde runs the local comunication II/352 between villages Švábka and Měšín. The bridge demolition is part of the D1 renovation plan. The main reason behind the demolitions si that the bridge no longer meets it´s lenght requierments. During the demolition and construction will be any use of II/352 for public transport over the bulding site forbiden. This diploma thesis include technical report for construction technology project, time and financial evaluation of the project. Also the thesis deals with the selected technological regulations of carried out activities, timetable of controls and tests, trafice relationships on wider scale, a list of main building machines and mechanisms with their specification, a concept of the construction site, health and safety requlations, and in detail plans for realization of a road surface layers.

CONSTRUCTION-TECHNOLOGY PROJECT OF BRIDGE DEMOLITION AND BRIDGE CONSTRUCTION
Hofírek, Radovan ; Venkrbec, Václav (referee) ; Henková, Svatava (advisor)
This diploma thesis deals with the demolition of a bridge located at the D1 motorway from Prague to Brno. The bridge no longer meets the load and width requirements of today´s standards. The thesis also deals with the construction of a new bridge, which will be expanded into D28/120 category. This expansion will allow for provisory use of the carriageways of one half of the motorway in both directions. The whole reconstruction is very time consuming that is the reason the new bridge is made of prefabricated pre-tensioned girders with a composite bridge deck. This can save time and the new bridge can be open for service in a shorter period of time.

Chimney demolition modeling
Ficker, Tomáš ; Keršner, Zbyněk (referee) ; Frantík, Petr (advisor)
The thesis deals with solving of a discrete dynamic 2D model of a chimney during its demolition. Specific goal of the thesis is to clarify observed phenomenon that is a break of the chimney while falling. The model of the chimney is designed and solved using software FyDiK which is able to solve dynamic effects. For verification of results, two models of chimney have been designed.

Operative diagnosis when assessing the state the family house
Novosad, Tomáš ; Balkanský, Ondřej (referee) ; Schmid, Pavel (advisor)
This bachelor's thesis deals with operative diagnosis when assessing the state of the terraced family house in Olomouc-Nedvězí. It describes executing of the technical construction research of the building. Due to the bad condition of the house it explores legal procedures of demolition in theory and their practical application. Findings of the diagnostics research serve as the basis for the preparation of the technical documentation for the purposes of building approval process to commence demolition.

Design of excavator
Brza, Lukáš ; Zdařil, Zdeněk (referee) ; Křenek, Ladislav (advisor)
The design of the excavator follows requirements of machines for demolition work. The excavator is equipped with an innovative type of under carriage, which not only increases mobility over the demolition sites but also the visibility from the driver’s cabin. The components of the excavator, that improve the demolition work, are special types of tracks, suspensions and articulated steering. Tracks can change their shape to increase the stability and also to adapt to the diff erent types of ground. The suspensions with tracks are able to adapt to the terrain thereby they lighten the asperity. Suspension can also tilt or even raise the excavator and thereby increase the angle of visibility from the cabin. This function is necessary mainly when taking down higher constructions. Articulated steering is a new function that has never been used for excavators. This steering was chosen due to fl exible movement over demolition sites. The main aim of the project is to create a new design of the excavator, but more importantly to distinguish the excavator from the excavators already on the market, with regards to its esthetics and under carriage innovation.

SUBSTRUCTURE OF A TRAINING CENTER OF COMPANY BATIST
Možíš, Jan ; Hanzelková, Martina (referee) ; Kantová, Radka (advisor)
The subject of my bachelor thesis is the construction-technological project of a training center of company Batist, Červený Kostelec. Thesis is focused on the most optimal technological procedures of demolition and groundworks along with base designs substructures. Regulations are supplemented by inspectional and trial plans, appropriate machinery and equipment of assembly site. Included is also work safety, time schedule and budget of substruture. The most interesting thing of my thesis will be comparison of the financial foundation with the original design of reinforced concrete structures on foundation along with compaction of the substrate, the design of the building foundation on bored piles.

Study the possibility of using recycled aggregate concrete for the manufacture of structural concrete
Skriňáková, Eva ; Stehlík, Dušan (referee) ; Hela, Rudolf (advisor)
This bachelor's thesis is aimed on the issues of using aggregate from recycled concrete rubble. The introduction describes the possibilities of concrete recycling and methods for fresh and hardened composite recycling. Next mentioned are physical and mechanical properties of recycled aggregate reused in concrete and comparison with natural aggregate concrete. Last part of theoretical section presents the opportunities of using recycled concrete to sub-base layers and concrete pavements. The practical section is focused on the application of recycled concrete aggregate to design concrete mixture of required strength class and verifying the possibility of usage in the exposure class XF3 and also design hydraulically bound course. The results of the practical section is to determine the suitability of recycled concrete usage for concept mentioned above.

Modernization of the sports complex with the construction of housing units
Ladomirjáková, Jitka ; Vítámvás, Zdeněk (referee) ; Sobotka, Jindřich (advisor)
The aim of the thesis was to create documentation for an extensive construction modifications of sports complex including the construction of housing units near Třebíč in the small village of Třebenice in Moravia. It was necessary to cooperate with the municipality and follow its requirements for the restoration of functionality and maintenance of individual operations for which the building was intended, hence the municipality considered them necessary in the future operation of the building. The project also included the design of paved areas and fencing of the playground. The main requirement of the municipality was to build a grandstand within the already built-up area of ??the object, and therefore part of the building is being demolished. This will change the layout of the basement and move the operation of the restaurant from the basement to the first floor with a view of the playground. Football players' locker rooms will be maintained in the basement, moreover a boiler room with air conditioning, facilities for referees and a club room with hygienic facilities will be added. On the first floor, the operation of the offices will be partially maintained and separated, and there will also be more space for a hairdresser and a restaurant. The last floor will be completely removed and rebuilt with a flat roof covering only half of the area compared to the current state. Following the current state, the 2nd floor will serve for housing, but as starting apartments for young families. The risers are made of autoclaved concrete and the new masonry is made of brick blocks for precise masonry. Over the restaurant is an extensive green roof and the roof over the apartments has a classic order of layers with a stabilizing layer of gravel. The building is contact-insulated with the ETICS system using mineral wool and the final layer is made of white exterior plaster. The plinth is lined with concrete cladding. Part of the restaurant is lined with wood on the so
