  • Condition monitoring, revision and operational tests for assessing the performance development of processes or individual components and need for overhaul and maintenance
  • Noise measurements and modelling (3D modelling of noise transmission to the area for environmental permitting needs)
  • Provision of technical advisors for annual overhauls and operation and maintenance planning

Extensive wind power measurements during development phase covering also arctic climatic conditions:

  • Implementation of meteorological measurements by means of mast measurements and supplementary soundings
  • Development of measurement systems

Wind power measurements in operational phase:

The perception of the interdependencies of operation and infrastructure forms the basis of our solutions for an infrastructure which is adapted to economic efficiency and operational requirements. We particularly focus on the structural implementation under the 'rolling wheel'.

The objective of facility management is to keep facilities in an operationally safe condition taking operational quality and profitability into account. Our services in this field range from ascertaining the actual status (inspection) and damage surveys, and the planning and tendering of maintenance and sanitation measures through to the monitoring and final inspection of construction services. The services are rendered either individually or as a complete package.

In case of private railway operators we can offer the whole railway infrastructure management including the provision of a railway manager for the operation.

Our main services include:

  • Operation and maintenance concepts, manuals and planning
  • Operational recommendations concerning track planning and infrastructure
  • Tendering and supervision of maintenance and repair
  • Provision of the railway manager for private railways
  • Cost and time management
  • Coordination of safety and health protection
  • Emergency management, organisation of winter service
  • Setup and operation of information systems
  • Maintenance-Control for all civil structures
  • Infrastructure Management System (IMS) for economic analysis
  • Trackwork Control for on-site track diagnosis
