A large-scale
construction site
Its architecture is intended to be sober and elegant: a "city ground floor", composed of glass and wood facades 11.50 metres high, will be open to the public space and the neighbourhood. It is at this height that the terrace, planted with some fifty trees, will overlook the reception areas and allow visitors to stroll around the facility at 360°.
Outstanding
Technical Building Control (TBC) assignments
With the main task of guaranteeing the solidity of the works and the safety of users, Apave must also ensure the acoustic and thermal insulation of the buildings, as well as compliance with the regulations on accessibility for the disabled.
According to Eve Brunelle at the City of Paris, this large-scale project is exceptional. "It was launched under a CREtM (Design - Build - Operate - Maintain) contract. This means that we are working with a joint venture made up of the entire project management team (architects, design offices, prevention specialists, etc. ....), the general contractor and the maintenance company.
This project, in which Apave is a stakeholder, represents a real challenge due to its specific and unique characteristics, which go beyond the CTC mission and mobilise all of Apave's expertise:
- With more than 6,000 m2 of green roofing, a process never before implemented on this type of roof, and 1,700 m2 of planted terrace, this represents a real challenge for the inspections of the infrastructure (lattice girders with a span of 80 m in the longitudinal direction and 60 m in the transverse direction)
- Recycled plastic bleacher seats from the circular economy, which requires expertise in bio-based materials for durability and strength
- Compressed mud brick partitions from the Grand Paris Express excavation, also involving an appreciation of bio-based materials, but above all an increased knowledge of thermal and acoustic issues.
We awarded this project to the Apave teams, thanks to their skills and experience in Technical Construction Control.
A project with undeniable
environmental qualities
Biobased materials will be used extensively, with 100% wooden frames for the two gymnasiums, mixed wood-concrete floors and the use of recycled cotton for the insulation of the main hall.
To reduce the building's carbon footprint, in addition to the use of wood, 30% of the concrete used for the construction will be from low-carbon sources.
The future Arena will also house a district cooling plant using local geothermal energy. This installation will provide all of the future Arena's cooling and heating needs in the short term.
With more than 6,000 m2 of green roof and 1,700 m2 of planted terrace, 80% of the future Arena's horizontal surfaces will be covered by nature.
