Head of Department, Tunnels
T: +45 51615202
We work with ventilation requirements for air quality and safety, and make evaluations of fire fighting access within tunnels - including making simulations of conditions that can be expected during a fire. Analyses can then be made of fire and smoke spread, and together with evacuation modelling and planning will act as input for a final Risk Analysis. This expertise resides in separate department, Risk and safety.

Nordhavnsvej – Copenhagen Municipality

Nordhavnsvej – the largest road construction project in Copenhagen in 50 years

The project for “Nordhavnsvej” is the first stage of a new road to Copenhagen’s Nordhavn (North Harbour). Nordhavn is an old industrial and port area, planned to be developed into a new urban area in the north-eastern part of Copenhagen. When fully developed, the urban area is planned for 40,000 residents and 40,000 workplaces.

Ramboll is responsible for planning and design of the stretch of tunnel from Söder Mälarstrand to Södra Station on the Stockholm City Line and for designing tunnel ventilation, general ventilation as well as smoke and heat ventilation.
