Cityringen Metro extension Sydhavn is a 4.5 km tunnel line with 5 stations. Ramboll acts as independent safety assessor for civil works.

The branch off to Sydhavn is the extension of the Copenhagen Cityringen metro which will serve the southern part of Copenhagen and will support future extension to the south east regions of greater Copenhagen.

Ramboll is employed by Metroselskabet to act as Independent Safety Assessor for the underground civil works design and built contract. This contract covers the assessment of the design by the design and built contractor for 5 underground stations, 2 technical charts, 4,5 km of twin tunnels and electrical and mechanical systems such as station and tunnel ventilation, fire alarm and fighting system and related SCADA.

The overall goal of the safety assessment is to support the authorisation process by the Danish National Safety Authority which includes:

  • Partial Building Permit, based on preliminary design
  • Safety Notifications to support construction activities, based on detailed design packages of each structural elements
  • Final Building Permit - Permit to use of the stations based on As Built design and Safety Cases

The assessment work is executed by a team of assessors covering the following disciplines:

  • Retaining structures and excavations
  • Permanent structures 
  • Tunnelling 
  • Geotechnics 
  • Hydrogeology Building Damage Assessment and Monitoring 
  • Electrical systems, including SCADA
  • Mechanical systems, including ventilation, fire alarm and fighting systems
  • Construction risk (property loss and injury to third parties)
  • Operational safety (based on EN50126 and CSM-RA)

The objective for Ramboll as Assessment Body is to perform an independent assessment of technical design documentation according to applicable standards and regulations and to assess the operational safety and construction risk management processes carried out by design and built contractor.

The project has started in 2018 and it is currently under construction. It is expected that the Civil Works structures will be completed and handed over for operation by 2024.
