Preparation of the Building Order
Vítek, Marek ; Mikulinec, David (referee) ; Waldhans, Miloš (advisor)
The topic of this bachelor thesis is the preparation of construction contract. The first part of the thesis is theoretical and focuses on basic concepts of project management, project life cycle, planning of resources. In the practical part there is described contract for construction of pre-treatment of waste water. Result of this thesis is documentation design of development planning from the time, costs and contractualisation aspect.

The concrete with a higher resistance to high temperatures
Mikulinec, David ; Hela,, Rudolf (referee) ; Bodnárová, Lenka (advisor)
The result of this master’s thesis is acquaintance with the issues of cement concrete resistance to high temperatures. This work describes the processes ongoing in the structure of concrete at extreme thermal loads and analysis of effects of high temperatures on the individual components of reinforced concrete structures is given, then influence of high temperatures and fire on the aggregates, matrix, reinforcement steel and the resulting changes in their properties. In the experimental part is given design of composition of concrete with a higher resistance to high temperatures and subsequent verification of the physico-mechanical properties of sample of concrete after exposure to temperatures at intervals of 200 ° C, 400 ° C, 600 ° C and 900 ° C. In individual recipes were observed changes of volume weight, changes of compressive strength and tensile strength flexural , tensile strength of surface layers and the occurrence of cracks and then were compared the results of thermally loaded and unloaded samples. The benefit in this issue is to evaluate the surface appearance of samples after heat load - study of area of crack and measurement of their width - was used according to the methodology's authors Xing, Hebert, Noumowe a Ledesert given in Cement and Concrete Research. This methodology allows to quantify changes of surface, after temperature load.
