Transport infrastructures

CEMOSA performs a research line in the field of railway and road infrastructures. The activities carried out in this research line comprise the whole life cycle of the infrastructures, from planning to operation and maintenance, including innovative design, use of new materials, advanced monitoring and information systems, among others. CEMOSA’s capabilities in this field are listed below:

  • Innovative infrastructure design: Integrated Innovative Engineering (I2E) where a multidisciplinary team performs the design of new infrastructure elements using expert knowledge in: advanced numerical models, both geotechnical and structural; advanced mechanical models, developed from material characterisation at laboratory; and prototype validation with integrated monitoring.
  • Intelligent maintenance: During the exploitation phase of infrastructures, maintenance use to be the main source of costs as well as a major capacity limitation. The application of Information and Communitcation Technologies (ICT) may improve the maintenance efficiency. Within this area, CEMOSA develops advanced algorithms to predict defect degradation, deploys asset management systems provided with decision support tools for maintenance planning, develops effective maintenance procedures based on new technologies and carries out Reliability, Maintainability, Availability and Safety analysis (RAMS).
  • Advanced monitoring: New solutions in infrastructure and maintenance usually requires innovative monitoring solutions. A monitoring strategy developed by structural and geotechnical engineers ensures that the necessary parameters are measured effectively in order to assess the structural health of the infrastructure elements. Some of these solutions deal with low-cost wireless sensor networks integrated in the infrastructure during construction and using Operational Modal Analysis (OMA) for defect detection.
  • Impact assessment: Life Cycle Costs (LCC) and Life Cycle Analysis (LCA) are cutting-edge techniques for impact assessments, however the methodologies stated in regulations and the available software tools are not tailored made for transport infrastructures. Thanks to its large experience as engineering company, CEMOSA have an exclusive and unique cost and impact database to develop this type of analysis, as well as a own methodology for the development of new projects.

These topics are developed in the research projects where CEMOSA participates; in particular the railway infrastructures area has ensured a medium-long term continuity thanks to its recent membership in the Shift2Rail initiative (www.shift2rail.org) of the European Commission.
