Planning maintenance costs is not an easy task. The amount of costs depends on many factors, such as value, age, condition of the property, availability of necessary resources and adopted maintenance strategy. The paper presents a selection of models which allow to estimate the costs of building maintenance, which are then applied to an exemplary office building. The two of the models allow a quick estimation of the budget for the maintenance of the building, following only indicative values. Two other methods take into account the change in the value of money over time and allow to estimate, assuming the adopted strategy and assumed costs, the value of the current amount allocated to the maintenance of the building. The final model is based on the assumptions provided for in Polish legislation. Due to significant simplifications in the models, the obtained results are characterized by a considerable discrepancy. However, they may form the basis for the initial budget planning related to the maintenance of the building. The choice of the method is left to the decision makers, but it is important what input data the decision maker has and the purpose for which he performs the cost calculation.

The paper deals with the issue of evaluation of socioeconomic impacts of occurrences emerging from railway infrastructure. The presented research results form part of a broader research subject focusing on the evaluation of the socioeconomic benefits of projects for the implementation of measures aimed at increasing the safety and reliability of railway infrastructure. The research topic addresses a part of the evaluation of railway infrastructure project efficiency within its life cycle using the cost–benefit analysis method. The methodology is based on the description and definition of input variables that are essential for the process of evaluating socioeconomic impacts. It is followed by another important step, which is the analysis of the categories and the number of occurrences, separately, for regional and national lines, and, further, the data is sorted according to whether occurrences emerge at stations or on a wide line. The result of the presented research is an overview of the calculated values of the expected socioeconomic impacts of partial occurrences according to the categories related to the year of operation on the railway infrastructure and the unit of measure. The research team carried out an inquiry into the annual impacts of the subcategories of occurrences related to one railway station and one kilometer of wide line, e.g., for national lines, the impacts of €2922.72/station/year and €41.67/km of wide line/year were determined. The results of the presented research represent important and necessary inputs for the next phase of the research topic, i.e., the evaluation of the socioeconomic benefits of projects increasing the safety and reliability of railway infrastructure.

The article discusses the impact of key factors on the economic development of the company operating in the Czech Republic. The aim of the research is to analyze the magnitude of key parameters changes on the indicator of the economic development of the construction firm. On the basis of accounting data, average values as default values for the analysis were determined and change of these variables on the resulting pointer was studied. This indicator has been selected from different methods of financial analysis. Pyramidal decomposition of return on equity, also called Du Pont pyramid is taken into account. Changes in values acting on the economic development of the construction enterprise are recorded using of sensitivity analysis method. Conclusion of the article focuses on describing the resulting values which were determined based on sensitivity analysis with the impact on aggregate indicators of financial analysis.

This article focused on comparing the development of the price level of the water and sewerage charge rates in the regions of the Czech Republic to the development of macroeconomic indicators expressing the performance of the individual region. The following were selected as macroeconomic indicators: gross domestic product, gross domestic product per capita, net disposable income of households, net disposable income of households per capita and average gross wage. The Czech Republic is divided into 14 regions. In each region, a different price level of the water and sewerage charge rate was determined. At the same time, each region had a different performance which is represented by the above-mentioned macroeconomic indicators. It follows from the definition of Act No. 274/2001 Coll. on the water supply and sewerage systems operation is in the public interest. This raised the research question of whether regions with lower performance also have a lower price level of water and sewerage charge rates from the point of view of the purchasing power of the inhabitants of this region. Confirmation or rejection of this hypothesis was based on the creation of 91 matrix expressions. The input data for the creation of matrices contained 196 items of data on the price level of the water and sewerage charge rates and 1,176 items of data on macroeconomic indicators. The hypothesis was not confirmed as only one region met the condition (Olomouc Region), which had a lower price level of water and sewerage charge rates and lower efficiency.
