Vienna, August 2012:
In cooperation with the Vienna University of Technology, ASFINAG's rehabilitation and maintenance management were analyzed and recommendations for further development with regard to an optimal, integrated system for all systems (asset management) based on the state of the art in technology and science have been developed. The existing approaches with the analyses and recommendations of TU Wien - Institute of Transportation have been the basis of ASFINAG's maintenance strategy in the last decade.
Project title
Analysis of maintenance and rehabilitation management at ASFINAG - analysis and evaluation of used methods and development potentials
Customer
ASFINAG
Type
Research project
Duration
September 2011 to April 2012 (revisited 2018/19 with data and models from Habilitation)
Partner/Role
Vienna University of Technology - Institute of Transportation with Prof. Blab with project concept and analysis of asset stock and methods being used on pavements, bridges, tunnels, and electrical equipment
Project goals
Analysis and evaluation of the applied methods in the maintenance management of the road infrastructure of ASFINAG as well as potential analysis and strategy recommendation.
Pavements: Analysis of ASFINAG's pavement management system with the presentation of the methodological basis from condition survey and condition assessment to planning, optimization, and implementation
Bridges: Analysis of the structural bridge management with a periodic condition survey, assessment (grades); risk assessment, M&R planning, and implementation
Tunnel: Analysis of the constructional tunnel management with a periodic condition survey, assessment (grades); risk assessment, M&R planning, and implementation
Electrical equipment: Analysis of inventory and condition recording, risk assessment, and retrofitting strategies
Results:
Analysis of general condition distribution and investment environment, group environment and risk management, inventory (systems, traffic, LOS, accident development, expenditure, condition development), maintenance strategies, methods, and instruments for superstructure, bridges, tunnels, and electrical machinery with summary and recommendation. The following objectives are essential for the further development of the methods and instruments used in the ASFINAG EMS with regard to an optimal, integrated system for all road systems (asset management) based on the state of the art in technology and science:
Providing a safe road network
Providing a comfortable, reliable road network with high availability
Securing the value of fixed assets
Economical and appropriate use of resources
Taking into account the impact on users, the environment / third parties, and the economy
Recommendations are reflected in the implemented maintenance and rehabilitation strategy of ASFINAG until today. Further development of the currently used methods and asset management tools shows a savings potential of at least 10-15% with annual investments of € 500 million in rehabilitation as a basis (see Habilitation Hoffmann).
