Construction group BESIX has been appointed by commercial real estate firm Unibail-Rodamco-Westfield (URW) to construct the Tour Triangle in Paris, France.
Designed by architects Herzog & De Meuron, the 180m-high Tour Triangle will comply with the BREEAM Excellent, HQE Exceptional environmental certifications and the Effinergie label.
The company’s in-house design office, BESIX Engineering has developed the planning, logistics and construction methods for the new development to minimise the impact on local mobility and operation of the Parc des Expositions.
Additionally, the design office team will undertake execution studies for the structure and support those dedicated to the façade.
BESIX France director Andres Penaloza said: “The Tour Triangle is the latest addition to our ongoing projects in the Paris region. In perfect collaboration with URW, our engineering and operational teams have worked meticulously to optimise the construction process and deliver the high quality required by our client. All our teams are now mobilised.”
Slated to complete in 2026, the development will include a conference centre, a cultural centre, a hotel, a health centre, a restaurant, a crèche and office space.
