Kungliga operan, Stockholm
The Royal Opera, Stockholm

About the Object
The Royal Opera in Stockholm was built between 1892-1898. Since first being commissioned the building has undergone numerous extensive renovations and reconstructions.

How have we assisted the project?
Brandskyddslaget has collaborated with the National Property Board of Sweden for more than 12 years on numerous projects.

In the case of the Royal Opera, the building and operations are very complex. This means that there is a need for flexible solutions that do not limit the scope of the cultural activities while preserving the heritage value of the building, which is an invaluable national treasure.

Brandskyddslaget is presently working on the project A New Opera in the Opera (NOiO), where the aim is to, amongst other things, create an additional scene for 300 visitors. The building is to be opened-up, both to allow access to more activities and to make the building more accessible to people walking in off the street.

We have conducted continual risk assessment of the entire building across the year. We have also conducted investigations into the following:

  • Doors and glazed partitions
  • Fire cells including fire seals
  • Reconstruction of scene machinery above and below stage
  • Reconstruction of fire gas ventilation in the stage area including the air supply
  • Adjustments for new activities, for example to accommodate new restaurants and bars
  • Operakällaren and Café Opera (two restaurants in the building)
  • Evacuation of the Gold Foyer
  • New sprinklers for the stage area and associated technical systems

Nationalmuseum, Stockholm
National Museum, Stockholm

About the Object
The National Museum lies in the center of Stockholm at Blasieholmen and was completed in the year 1866. It is Sweden’s largest, and one of Europe’s oldest, art museum. For the first time in 150 years, it has undergone an extensive renovation. The renovation began in 2013 and was completed in 2018.

How have we assisted the project?
Brandskyddslaget participated in the extensive reconstruction project from the preparatory study conducted in 2007. After completion of the preparatory study, we did participate in all phases of the project including, program documentation, system documentation, and building documentation. Skanska, the lead contractor, has handed the building over to the National Property Board of Sweden, and in conjunction with that Brandskyddslaget provided the Fire Protection Documentation. This documentation provided the basis for the final approval from the Stockholm Planning Office. The cost of the project is estimated to be over 1 billion SEK.

We have collaborated with a range of different consultants, but particularly with Gert Wingårdh’s Architects. They are also the consultants that have been most active in developing the fire protection drawings together with us.

The greatest challenge for us has been to ensure that the museum can allow 2 000 people to be on site at the same time, even though certain stairwells are too narrow. This was solved by opening two previously closed existing stairwells, by incorporating sprinklers into the building and by installing fire gas ventilation in the main stairwell. We have used analytical design to show that the Swedish Building Requirements (BBR) have been fulfilled.

The sprinkler system is comprised of water filled plastic piping, that is not under pressure. To activate the sprinkler system, it is necessary for both smoke and sprinkler detectors to be triggered.

To ensure the best possible conditions for the evacuation of visitors with restricted mobility, two evacuation elevators have been installed together with so-called evacuation refuge locations. To facilitate potential extinguishing operations for first responders, special passage cards and response plans have been developed. These have been revised as needed.

Brandskyddslaget has also conducted hot smoke tests to verify the operation of the suction fire alarm system. Additional such tests are planned in conjunction with other performance verification prior to the final inspection.

Gamla Wermlandsbanken, Karlstad
Wermlands Bank, Karlstad
Read More

About the Object
The old Wermland Bank building is one of the most impressive buildings in Karlstad. The Bank Palace was built at around the turn of the century (approx. 1906) and stands as a symbol of the important role that the bank has had in the economic development of Värmland. The building has significant architectural, esthetical and environmental value. Since 1993 it has been declared a heritage building with legal protection of the exterior and large parts of the interior of the building.

How have we assisted the project?
Brandskyddslaget has been involved in the design of the fire safety in conjunction with the reconstruction in 2016 and 2017. The building was opened for the public and contains a restaurant. The building is in direct connection to a new commercial shopping mall.

The project has placed high expectations on the fire safety while at the same time endeavouring to maintain the marble, mahogany and wall murals in their original condition. The building has also been adapted to accommodate handicap access. The fire protection has to a certain degree been developed analytically to minimise physical encroachment on the building and to maintain the existing open floor plan. An inventory of the existing fire safety was necessary as part of the design.
