Forming part of a larger mixed used scheme, Varso Tower is the tallest building in Poland and one of the tallest in Europe
Building features a number of innovative sustainable features and is set to achieve a BREAM ‘Outstanding’
Safety within the tall building is paramount, with specialist systems installed to protect against fire
With health and well-being of business people and visitors alike, the building has already been awarded Europe’s first WELL Core & Shell Precertificate
Forming part of the flagship Varso Place development in central Warsaw, Varso Tower will be the tallest building in the European Union, featuring spectacular views of the city’s skyline from a 230m high observation deck. Sitting next to the Central Railway Station, the scheme marks the beginning of the regeneration of the area, adding vibrancy to a previously brownfield site.
Reaching 310m, Varso Tower will offer office space and a restaurant spanning the 46th and 47th floors, as well as shops and cafes on the ground level. The development will become home to many businesses as well as serving as a destination for tourists and residents of Warsaw.
A key challenge for the BuroHappold Engineering team was the proximity of the site to busy city centre streets, existing buildings and the main railway station. As well as solving problems stemming from where the land is situated, including vibrations caused from the railway line, we also had to ensure the railway tunnel remains safe to use during construction.
With aspirations for the project to achieve WELL certification, we needed to ensure that all of the services installations adhere to strict regulations and provide the best possible internal environment. Treading lightly on the environment is another key goal, with green design expectations taking a high priority in our brief.
We also had to carefully consider the location and scale of the services to make the most of the space available for lease, maximising income potential for our client.
The site is very complex, with railway station infrastructure running adjacent to the tower. Working in close collaboration with our client, we coordinated the development programme so that the works will run smoothly, completing the geological survey and demolitions while allowing the station to operate as normal.
To incorporate the highest possible level of energy efficiency, we conducted a thorough analysis of the potential for innovative solutions early in the project so that we could recommend a strategy that will have a positive impact on the performance of the tower. The sustainability strategy will see water and energy consumption reduced, with Varso Tower expected to receive a BREEAM ‘Outstanding’ certification. With a focus on future-proof design, we have carried out predictions as to how the mechanical equipment will be replaced or refurbished in 20-30 years’ time and used these to specify how equipment should be installed.
Safety is also a vital part of the project; especially given that the tower is one of the highest buildings in Europe. Our team are carefully designing the services to incorporate fire safety features such as water mist systems, hydrant systems, smoke extraction and air compensation required for the smoke extraction process. The building will feature a pressurisation system to guarantee safe evacuation for occupants, along with an internal wireless communications system that is approved by the fire authorities. In addition, there will be an early warning system that predicts thunderstorms.
To increase the amount of leasable space within the tower, our engineers used high strength reinforcements to allow the size of the superstructure column to be reduced. We also carefully planned the installation of the mist and HVAC systems to minimise the core area.
Setting the scene for the regeneration of this part of Warsaw, Varso Tower represents the future path of the city. As well as providing commercial accommodation of the highest standard, the tower also offers a showpiece for Poland as one of the highest and most energy efficient buildings in the region.
