Potential of Computed Aided Facility Management for Urban Water Infrastructure with the Focus on Rainwater Management

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.
