INFORMATION SYSTEM FOR COST ESTIMATION OF COMMUNAL INFRASTRUCTURE

misbe2011 Tracking Number 77

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, urban 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 urban development, in order to keep the budget of future remaining costs. For this reason, development strategies and important new projects have to be evaluated within their infrastructural running and life cycle costs. A current research project in cooperation with a German Municipality will enable the involved 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 and their drivers for municipal infrastructural project cost estimation in early project phases.
