Although the construction site at Silver Tower has never really come to a standstill, everything is now at full speed again and SECO is happy to once again take up its various tasks.
To guarantee the towers overall quality, SECO has been appointed by Ghelamco Group in order to apply its expertise in the fields of fire safety, stability, safety coordination and technical installations.
As a landmark in the Brussels scenery, the tower offered us some interesting technical challenges:
- The overall stability and rigidity of the structure is ensured by a reinforced concrete core and a system of metal struts located halfway up the tower.
- Given the location of the building between several other tall buildings, a wind tunnel test needed to be performed to determine the forces on the building. This resulted in important wind loads in certain places, partly due to the shape of the building.
- To obtain an excellent U-value with double glazing and the vertical decorative fins on the façade, the composition of the glass was modified with new coatings (anti-fog) and the type of anchor was made in a special stainless steel composition, to limit the thermal conductivity.
Because Ghelamco also sets high standards for total conformity in the field of fire safety, SECO provided them with its technical expertise and support in the domain.
Designated by the Brussels Region, Ghelamco Group is developing this project, an radiant office tower with an above-ground surface of 45,000 m², seven underground levels, a ground floor with two mezzanines and thirty-two further above-ground floors to accommodate the 2,000 officials of the Brussels-Capital Region from autumn 2020.
The building has the shape of an ellipse 28 m wide and 69 m long.
Its height is a towering 137 m.”
