Projet Silva: a wooden tower in Bordeaux

Egis is in charge of the engineering of a 50-m high wooden tower in the centre of Bordeaux in the Euratlantique perimeter next door to the city’s national wholesale market.

Date : March 2016
Contractor: Kaufman & Broad
Developer: Kaufman & Broad
Architect: Art & Build (Paris/Bruxelles) & Studio Bellecour (Paris/Bordeaux)
Wood companies: Intégrale bois système (Bordeaux), Sagba (Landes), Techniwood (Jura)
Commissioning date: 2022

Project overview

The SILVA project comprises three buildings covering a total of 17,700 square metres divided up between 14,200 m² of housing units bearing NF Habitat HQE certification, 3000 m² of office space with BREEAM “very good” certification, 500 m² of retail space and a car park.

With this program, the SILVA tower is projected to be one of the highest wooden towers in France and in the world, in view of the projects planned and known to date. Rising to a height of 50 m, this 18 storey tower supported by a primary structure with giant timber columns comprises more than 80% of wood.

Our missions

The building teams at Egis, Elioth (the group entity specialising in innovative structures) and Acoustb (Egis’s acoustics design office) are conducting all the engineering assignments relating to the tower: general structural and MEP design, economics, construction supervision and acoustics.

The project, which draws on Elioth’s specialist skills in the use of wood (Teamber by Elioth), is set to become an ambassador for French know-how in construction in this material. It is a new milestone in the journey towards the city of tomorrow.
