Project description / initial situation

• Increasing demands on the performance and reliability of the transport infrastructure in Germany
• Due to a wide variety of influences, a large number of infrastructure structures do not reach their planned service life
• Many infrastructure structures will reach the end of their technical service life in the coming years due to increasing use and their advancing age
• Currently, decisions about the measures during the useful life are made on the basis of the available property-related information.
• Obtaining information is difficult and time-consuming due to the heterogeneous quality of the as-built documentation.
• An advanced, intelligent life cycle management (LCM) can support this process substantially.

Challenge

• The current way of collecting and processing status data does not allow for preventive measures
• Development of the concept of a modular indicator-supported life cycle management with regard to quick, targeted and comprehensible decisions
• Elaboration of the different needs of the rail, road and waterway modes of transport Systematic collection of all relevant information in the form of parameters and timely and comprehensive evaluation
• The parameters and their combinations should take into account all structural, economic, socio-cultural and ecological concerns and requirements
• Development of two concepts that build on each other (object and network level) Identification of the relevant indicators and parameters at object and network level
• The information sources of the construction authorities (rail, road, waterway) serve as the working basis. The data are made available free of charge and can be in digital and/or analogue form. The procedure of the construction authorities (road construction administrations of the federal states, WSV, DB Netz AG) for recording the data should not be changed.

Measures

• Definition of terms, basics of life cycle management
• Analysis of existing systems
• Elaboration of the parameters and their combinations that are relevant for a transport carrier-overlapping LZM.
• Selection of the parameters and description of the added value for the assessment of building conditions compared to previous methods 
• Definition of the interface between network and object level 
• Validation of the concept based on pilot projects 

Benefit of the procedure for those involved:

• Universally applicable modular lifecycle management concept with a wide range of applications
• Linking of network and object level using SWOT analysis
• Weighting of buildings and measures using Paretro 
• The concept can be used in particular for the LZM of existing buildings
• Possibility of successive use and expansion of the concept
• Indicator-based damage risk assessment
