Selected problems in the process of building operation appraisal for the purposes of expert opinions
Novák, Jindřich ; Pivoda, Bohuslav (referee) ; Puchýř, Bohumil (referee) ; Mikš, Lubomír (advisor)
The basic requirement for a good quality expert opinion are high quality sources of information, i.e. adequately detailed and valid groundwork. This dissertation analyzes groundwork for expert activities in the area of building operation appraisals, handling of information and its transmission within the life cycle of a construction. For this purpose, it is possible to divide the construction according to its functional parts. The thesis puts emphasis on drawing up a budget according to its functional parts, which is clearer for the investors, contractors and real estate administrators as well as the expert. A significant part of the dissertation is dedicated to recommendations on how to determine the usual price of building operations. In this section I define some options of how to determine the usual price of building operations, including their comparison. Likewise, I investigated and compared real agreed prices of building contracts for public commissions. The basic recommendation resulting from this chapter is the recommendation for the Czech statistics department to automate the data collection based on registers of building operations created with one of the budgeting programs (preferably according to functional parts). For the experts, I prepared a set of recommendations based on the analyzed differences between the budgeted prices and those applied in real contracts. There is no generally accepted method to evaluate the losses created due to delays in construction. For the purposes of this dissertation, I investigated the common prices of rent of the individual equipment and then established two approaches to put value on the cost of equipping the site, percentage rate and individual calculation. I examine in more detail the issues related to quantification of costs for wintertime arrangements. At the end of the chapter I define recommendations for experts. With regard to recommendations for establishing discounts from the construction price due to occurrence of defects and unfinished tasks, I analyzed real examples of distribution of defects and unfinished tasks at the moment of delivering the building operation to the investor and discovered that approximately 50% of defects are part of the surface working. Additionally, I analyzed the Czech technical regulations regarding surface working in order to find basis for assessment of the presence or absence of a defect. While investigating the approach to non-removable defects, I discovered incorrectly considered shelf life of waterproofing within the appraisal. Based on this, I investigated the market and determined the shelf life of common waterproofing systems. At the end of this dissertation I carry out a comparison of selected items of the two pricing systems most commonly used in the Czech Republic, URS and RTS. The differences are a result of contemplating using different technologies, varied mechanisms and diverse approaches to determine the costs of material.

Use of advanced oxidation processes in pool water treatment
Trávníček, Jakub ; Pivoda, Bohuslav (referee) ; Biela, Renata (advisor)
The research part of the thesis is focused on the use of advanced oxidation processes in the treatment of swimming pool waters. In the first part, the common disinfection technologies that are used domestically and abroad for the treatment of swimming pool waters are described. In the second part, the research focuses on the basic types of advanced oxidation processes used in swimming pool facilities and other similar laboratory-scale technologies with potential for future use in the spa industry. The practical focus of the thesis consists of two parts. In the first part, data from a questionnaire of selected swimming pool facilities in the Czech Republic are processed, which summarizes what technologies are used in the treatment of swimming pool waters in the Czech Republic. The second part consists of a case study that analyses the effect on the quality of treated water before and after the installation of advanced oxidation processes system in the pool recirculation circuit.
