Real estate operations on the Triolet Campus (Newsletter #11 - March 2022)

Are we all asking the same questions about Building 6?

- Complete change of use of the building (currently 4 lecture theatres with 250 seats and TD/TP rooms on the ground floor) -> very high restructuring costs (demolish everything inside, including the concrete tiers in the lecture theatres, reinforce the load-bearing structure to accept higher loads, etc.).
- The building is in a very poor state in terms of energy efficiency (note: the energy renovation of building 05 alone cost 11 M€)
- In the end, the cost is lower if we demolish this building and build a new one.

- asbestos removal completed (mid-November to mid-December 2021)
- deconstruction from early January to March 2022 (from the center of the building towards the wings)
- start of construction of the new building in Q4 2022 (for 2 years of work... at least)

- dust -> permanent spraying of rubble to limit impact
- noise (machines, trucks, loading, etc.)
- vibrations

- fully enclosed site with opaque barriers around the perimeter
- truck and personnel access only through the gate located on the fire road
- company personnel made aware of the situation (work on an occupied site), reminder given recently

- wood, steel and glass materials evacuated to recycling centers
- several items recovered by DPI (spare parts, etc.)
- concrete crushed on site for reuse as filler material in the construction of the platform for the new building
- the remainder will be deposited in a landfill site for recycling

- environmental impact study (fauna, flora, natural habitats) carried out on Triolet in 2011, followed by a second study in 2020-2021 (Bât. 06 + Bâts. 01 to 04) by the consulting firm ECOTONE: ecological diagnosis based on naturalist inventories to identify fauna and flora issues (also used data established by the GNUM) -> 17 species at stake and/or protected (birds = 6, chiropterans = 6 -the most impacted-, mammals = 1, reptiles = 4)
- implementation of impact reduction and accompanying measures: staggering of the work period, installation of alternative nesting sites and a wildlife hotel, site monitoring by an ecologist (with a chiropterologist on assignment)
- submission of a dossier to the DREAL concerning this operation (in application of Art. L.411-2 of the Environment Code)

And after building 6...

What will replace this behemoth on the Triolet campus? It took just a few weeks to demolish it and clear away the tons of rubble from the building that had housed thousands of students since the 1960s.

You'll have to wait until the 2024-25 academic year to find out who will replace him. We're offering you a sneak preview of artists' views, so you can imagine what's coming next and look ahead 3 years.

In the near future, this new 4-storey Faculty of Science building will house the Mechanics Department, the Computer Science Department, part of the Physics Department, part of the EEA Department and numerous rooms and facilities for students, who will be able to work on a variety of projects in optimal conditions.

The building will also house the Preventive Medicine and Health Promotion service for students and staff, and provide additional premises for the Campus Life Department for various activities concerning the University's students.

We've been promised a functional building with numerous adapted rooms and, as the icing on the cake, a belvedere terrace next to S'PACE: we can't wait to discover this new building!

Other real estate operations are scheduled for next spring. From May to September, the renovation and restructuring of Building 19, which houses the FdS Chemistry Department, is scheduled.
