Resilience of Inland Urban Areas to Disasters Occurred Due to ExtremePrecipitations

Among possible manifestations of climate change, which, according to predictions for coming period, may oc- cur in different regions of Europe, are the extreme precipitations. These events, often accompanied by storms, may further lead to a whole series of consequences in urban environment and to the occurrence of disasters, such as massive floods. Starting from the description of case of Serbia floods 2014, this paper identifies some of the past human mistakes with ex- perienced (and possibly future) catastrophic consequences, gives overview of future climate change expectations in terms of extreme precipitation occurrence, considers possible negative implications on urban population, built environment and functions, and defines resilient city concept. Finally, the paper introduces strategic proposal on achieving flood-resilient cities. Proposed concept deals both with the mitigation of past errors and the introduction of new, climate-resilient prac- tice in further urban development. Time gap between future (with supposed achieved resilience) and present moment (with supposed high level of vulnerability and therefore risks) is overcome by definition of priorities and introduction of three different time-related categories of actions and results: immediate, short-term and long-term. Achieving social pre- paredness for possible extreme weather events represents the first important step in reducing the possibility of their nega- tive transformation into disaster.

Towards Life Cycle Complete BIM

The goal of Building Information Modelling (BIM) is the integral overarching digital modelling of all properties regarding a building as well as its construction. This is targeted through the integration and support of all involved experts. Due to the interdisciplinary nature of this task, the necessary data often only exists in a very fragmented and uncoordinated way throughout different departments. BIM tries to mediate between the different views of its users and allows for a coordinated accumulation of data, as well as synchronously keeping the planning status up to date. However, in most cases this available information is still not used throughout the complete lifecycle of the building. Clear gaps exist between the different phases of planning, construction as well as use and maintenance. Within this paper we aim to give an overview of possible BIM data, as well as its relevance for construction processes. This is especially considered from a process automation viewpoint, in order to identify the required interfaces as well as missing and irrelevant data for assembly processes within construction. Based on this a BIM informed design to production becomes possible. Primary goal is the development of strategies for the creation of BIM-aided planning processes that continue into actual fabrication and construction and are efficient in terms of time, energy and costs considering changing user demands and the resulting usage requirements. We address the lifecycle of a building using the concept of BIM. Therefore, we also consider the required information for future conversion and refurbishment of the building, in order to complete the lifecycle approach of BIM. Hence, we give a first brief overview of possible techniques for modelling pre-existing buildings within BIM, as well as the required level of detail (LoD). Looking closer at the LoD for different lifecycle phases.
