This paper of the BIM method to the existing buildings of VSB - TU Ostrava. The aim of the paper is to introduce the BIM method and the way in which this method is gradually implemented into three selected objects - nursery school, faculty of electrical engineering and informatics and faculty of civil engineering. During BIM implementation, 2D documentation is converted to BIM models and a digital twin is created.

In this study, we investigated the modelling and optimization of drinking water supply system reliability in the village of Zaben, Czech Republic. An in depth overview of the water supply network in the municipality, passport processing and accident and malfunction recording is provided based on data provided by the owner and operator of the water mains as well as the data collected by our own field survey. Using the data processed from accident and failure reports in addition to water main documentation, the water supply network in Zaben was evaluated according to the failure modes and effects analysis methods. Subsequently, individual water supply lines were classified based on their structural condition. In addition, a proposed plan for financing the reconstruction of the water supply mains in Zaben was created. As such, this study provides an overall assessment of the water supply network in Zaben alongside a proposed plan for the structural restoration of the water supply system, which accounts for the theoretical service life of the system and the financial resources of the owner.

Valuation of single-family detached houses is necessary when determining the amounts of some taxes. The current systems of the Czech Republic are outdated in this respect, and they are based on procedures used in the 1980s. The values found do not correspond to current market conditions very often. This article attempts to verify the applicability of a methodology where the value of a detached house is decomposed into the value of the land and the value of the object as such when considering wear. For verification, 122 sales of detached houses in Ostrava and its surroundings were analyzed, and the results show that the values determined by the verified methodology do not differ by more than 10% from the actual sales prices in most cases. The methodology is very simple and practically applicable for users without deep knowledge of construction or valuation principles. It can be applied, for example, when calculating the bases of certain taxes or as an indicative guide for the pricing of real estate for sellers, buyers, real estate agents, etc.

This article focuses on the information modeling of buildings and its subsequent extension to the information modeling of cities, which can be considered as the main topics of the construction industry development. It offers new knowledge for city management, facility management and other fields of construction sector. Information modeling of buildings and cities creates a suitable basis for the creation of various simulations (acoustic, thermal, environmental influence, sunlight or the spread of pollution) and analyses. Simulations and results obtained from them can help us in the decision-making phase, they predict problems or unexpected situations during the life cycle of cities and buildings, and thus make it possible to prevent their occurrence. In the second part of the contribution, an innovative model, the so-called R-WIM, is presented. BIM modeling methods were used for the research and extended to the public environment. The expansion of the public environment digitization enables to obtain a sufficient amount of information about the public space and then subsequently combine them with static weather data. This model deals with Urban Water Infrastructure with the focus on Rainwater Management and has been developed for the particular needs of individual municipalities in the process of solving problem situations associated with rainwater, which is very current due to climate change, and municipalities require appropriate tools to predict the behavior of rainwater so that various compensatory measures can be created.

Brownfields areas are one of the biggest problems of contemporary communities. These are old abandoned structures without adequate use and they cause many social, economical, environmental, medical and urban problems. So, it is possible to say, that brownfields are a very topical issue and its solution is fully in compliance with the principles of sustainable development. It is obvious, that brownfield regeneration and the above problems elimination have a significant positive impact on overall development of former brownfield site and its surroundings. So, a possibility of a forecast of this development based on mathematical model tools offers. Modified Dynamic Model (MDM) is one of these tools. This paper describes the possibilities of locality development modelling in the case of brownfield regeneration in the MDM environment. All these possibilities are shown on a practical example of chosen Czech brownfield for better understanding.

Brownfields are one of the most important problems, which today’s cities have to solve. Regeneration of them and their reintegration back to the city organism are very time-consuming and expensive. New development is realized on the edges of cities for this reason. However, this situation is not in accordance with sustainable development principles, but the situation is not only about finances and brownfield regeneration can have very positive effect on many other aspects. Software tool Modified dynamic model (MDM) facilitates to model the long-term development on the defined factors basis. Thus, it can be convenient to model the land development in the case of brownfield regeneration in this software and to compare this situation with greenfield development. On the basis of results, we can find that brownfield regeneration is more effective in the long run. Then, these models can help potential investors with decision about their finances investment.
