Transaction Schedule

Work in progress

On the west side of the building, completion of the metal framework and structural work is scheduled for late autumn 2023. The final waterproofing work on the top level is progressing on the western part of the building, to ensure that it is watertight and to fully launch the work on the various secondary interior trades.

The technical trades are still working on the current floors of the entire site, while the architectural trades are working on the current floors of the eastern zone. Façade work is nearing completion on the upper floors to the east of the building. Façade work on the west side of the building will begin in the next few weeks.

As for the façades of the Atrium, work began this summer on the Esplanade façade, as well as on the façade facing the heart of the block/Cours Michelet.

Focus on the dismantling of the cranes and work on the PRM passage between the Cours Michelet and the esplanade

The Lightwell cranes were dismantled in October. One crane dismantled the other, then a mobile crane dismantled the second.

Now that the cranes on our site have been dismantled, we can finalise the waterproofing work on the heart of the block, the area crossed by the PRM passageway at the heart of our site, which we've been working on since August.

In order to carry out our work safely and to guarantee everyone's safety, we are occasionally closing access to the PRM path during the day. However, the PRM path remains accessible at all times. A telephone number is available for opening access to the PRM path (see below).

Don't hesitate to use it, an agent will come to open it for you and help you cross if necessary. PC Sécurité Lightwell: 07 64 33 18 00
