Infrastructure Cost Planning-Information System for Cost Prediction of Communal Infrastructure

摘要

As in many industrialized countries, the population of Germany is constantly getting older and smaller nowadays. These demographic changes cause adaptations of technical and social infrastructure in both quality and quantity, to ensure their aspects of economy and usability at long term. Therefore, settlement development planning and municipal infrastructure planning have to work closely together. Decisions like expansion, renovation, re-dimensioning or even closing of municipal infrastructure should be based on long term strategies of settlement development, in order to keep the budget of future remaining costs. As well as development strategies and large new projects have to be evaluated within their infrastructural running costs. A current research project, together with the City of Stuttgart, will enable the planning teams to systematically integrate the consequences of demographic changes in their infrastructural projects in terms of supply quality and cost efficiency. As part of the project, this first study prepares the database of cost indicators for municipal infrastructural project cost estimation in early project phases.
