- ItemThe Effect of Railway Projects Increasing Safety on the Frequency of Occurrences(MDPI, 2024-10-09) Hromádka, Vít; Funk, TomášThis contribution is focused on the presentation of individual research results aimed at evaluating the socio-economic impacts associated with increasing the safety and reliability of the railway transport route. The goal of the research is to propose and subsequently verify an original approach for assessing the impact of the implementation of investment projects, including measures aimed at increasing the safety and reliability of railway transport routes, on the resulting number of occurrences that happen on the railway in the Czech Republic. The proposed procedure is based on several key documents. In addition to already existing national methodologies, these are mainly the database of occurrences managed by the Railway Administration of the Czech Republic, including approximately 1000 occurrences for each year of the evaluated period (2009–2018), and information on 33 projects on the railway transport route, where the effects of their implementation on the overall frequency of occurrences are examined events in the subject location. The output of the research is a methodical approach for assessing the impact of the implementation of projects aimed at increasing the safety and reliability of the railway transport route. We perceive the impact on the occurrences from the point of view of the frequency of their occurrence and from the point of view of the socio-economic impacts that are achieved as a result of the implementation of the projects. From the point of view of the frequency of occurrence, a reduction in its value of 4.63% was found. As part of the research, the impact on the occurrence of extraordinary events is also assessed in the context of the scope of the railway transport route, both with regard to the length of the reconstructed track and also with regard to traffic performance.
- ItemManagement of the Territory Restoration Process Following a Disaster: The Case of the South Moravian Region in the Czech Republic(MDPI, 2024-10-14) Hromádka, Vít; Helešicová, Barbora; Nováková, JanaThe article presents a methodology for the management of repairs to property damaged by a disaster. The article describes the procedure for the development of an organizational layout, along with planning and managing activities leading to the restoration of damaged property. Last but not least, the article deals with financial planning. The methodology presented was applied to a case study that was conducted in the village of Hru & scaron;ky, South Moravian region, the Czech Republic, which was hit by a tornado in 2021. More than three years have passed since this tragedy, and repairs to the village's property are still planned to continue until the middle of 2025. Qualitative approaches to data collection and evaluation were used for data collection, especially in-depth interviews related to the given issue. The mayor of the village, the village management, and representatives of construction companies were involved in the in-depth interviews. Another important source of data was the project documentation and the municipality's accounting records. The main outputs include a list of construction works, which served as a basis for the financial damages; the municipality's participation in state subsidy programs for the financing of the restoration; and, last but not least, a list of works that was used to create the project documentation for the reconstruction of individual buildings. Other outputs of the work include a structural plan, which has been developed for the purposes of planning and managing activities leading to the restoration of the damaged area, and a financial plan, which contains information on expenses and funding sources. The key contribution of the paper is a methodical procedure for the identification, the design, and the execution of crucial activities connected with the restoration of the territory after a disaster. The methodological procedure is designed considering the experience associated with a specific disaster, namely, a tornado in the southeastern part of the Czech Republic, which served as the basis for this case study.
- ItemPricing of water and sewerage charge rates of a selected water management company in the Czech Republic – a case study(EDP Sciences, 2024-07-16) Oblouková, Aneta; Vítková, EvaThe article deals with water and sewerage charge rates issues in the Czech Republic over the last 4 years. This article is focused only on part of the research. Research is based on data collection. The data were obtained from the internet portal eAGRI.cz. The aim of the article is to describe the development of water and sewerage charge rates in the Czech Republic during the last 4 years (2018-2021) and to analyse the pricing of a selected company in the Czech Republic. First, analyse the average water and sewerage charge rates system in the Czech Republic in the monitored period, then define the average water and sewerage charge rates system for the individual regions in which the selected water management company operates. The goal of the research is the analysis of the individual components of the calculation formula of the selected water supply and sewerage operator in the Czech Republic, namely the joint-stock company Brněnské vodarny a kanalizace, a.s. The vertical analysis methodology is chosen for data evaluation. The analysed operator has the largest representation in other direct costs and material in the calculation formula.
- ItemUsage of Building Passports and BIM in Multi-Criteria Evaluation(Elsevier B.V, 2024-07-29) Tuscher, Martin; Hanák, Michal; Navrátilová, Vladimíra; Tichá, AlenaThis paper presents a proposal for a multi-criteria evaluation methodology for partial building structures. The use of the multi-criteria methodology allows, in contrast to the usual assessment of the sustainability of buildings (e.g. for building certification), the assessment of individual building structures, which is essential, especially for the renovation or reconstruction of existing buildings. The survey aims at administrative buildings of public administration, however, the design of the methodology can be applied to a variety of building structures. The authors carried out research into innovative ways of using building information tools that are important for making the overall property management in facility management more efficient. The paper focuses on the possibility of using information based on these building information tools. One of the possibilities how to make building management more efficient and increase human performance can be using building-specific information along with providing a pleasant healthy workplace. Maintenance, renovation or reconstruction represent a significant cost over the entire life cycle. However, it is necessary to set limit conditions defining the level above which the condition of buildings should be maintained in relation to their purpose and demands placed on them. The article also responds to an anticipated EU decision that shall lead to renovations or reconstructions of office buildings as a result of efforts to reduce their emissions impact and energy intensity. Thanks to the proposed methodology, the owner which specifically in this article is the state and public administration, will be able to better evaluate both the financial impact and other criteria important for the choice of a specific type of construction, product and implementation procedures.
- ItemIncluding Carbon Dioxide and Sulphur Dioxide Production in the Lifetime Costs of Buildings(Elsevier B.V, 2024-07-29) Federla, Jakub; Korytárová, JanaReduction in the consumption of operational (primary) energy and emissions of harmful gases has recently become the focus of attention of the civil engineering sector. In this context, there is also emphasized the energy consumption and emission production values associated with the whole life cycle of the construction materials used, which is referred to as “bundled energy consumption” and “bundled emissions”. This paper analyses the energy performance certificates in combination with the SBToolCZ methodology. Sustainability Building Tool is a methodology designed to assess the sustainability of buildings. This methodology is used to assess the environmental impact of buildings at different stages of their life cycle, such as production, operation and demolition of the building. The amount of carbon dioxide and sulphur dioxide produced during the life cycle of buildings was determined by analysing and extending the building assessment data by the SBToolCZ methodology, which was subsequently valued and incorporated into the lifetime costs. The data from 17 case studies from the Czech environment were analysed. Taking these environmental impacts into account, valuing them and analysing the cash flows of investors and society shows the importance of paying increased attention to sustainable construction and reducing its negative impact on the environment and climate. Research data shows that 30% of the operating costs of buildings are the societal costs associated with CO2,eqv. and SO2,eqv. production.
