Social inclusion and safety 

The association Pépins production is the winner of the Call for Events launched by La Sablière to co-build a railway incubator located at 2 rue des Coudreaux, which offers weekly activities throughout the year for volunteers of all ages. The railway incubator is a place open to all associations and services to residents to offer activities that federate.

The support of the City of Chelles makes it possible to welcome extracurricular and school children from the Arcades Fleuries et Lise London establishments every week. Open doors are held every Wednesday and Saturday for all our tenants with various entertainment. The dense program is a good illustration of all the efforts made by the Sablière in favor of social cohesion.

Mobility strategy

• Maintaining an effective public transport offer (TCSP under study by the community);
• Establishment of a cycle network and bike rooms.

SOLUTIONS

Maquette BIM

Description :

Rehabilitating the 552 housing units of the Cité Cheminote involves taking into account three different construction periods and therefore requires setting up three work programs with specific materials and colours. To manage this project, which will run from summer 2020 to the end of 2024, the teams opted for a simplified BIM model that is accessible to all companies. The idea is to facilitate access to reliable and up-to-date data for everyone. Even novices can access the glued model and know the work carried out, the equipment replaced, the reception and the lifting of reservations, etc.

Biodiversity and natural areas

• Inclusive, permeable (valleys) and intensely planted public spaces;
• Enhancement of biodiversity both at the public and private scales.

Buildings

Given the diversity of pavilion typologies, the work program varies according to the years of construction.

€67,000 have been invested on average per dwelling, for savings on post-work charges between €19 and €120 per year.

3 operational teams are mobilized for the 3 types of pavilions. During the works, the constraints are limited to the maximum and several devices guarantee a continuous dialogue with the tenants.

At the end of the works, the buildings originally with an energy label G, F or E are switched to a D or C label.

A common program

• Revision or repair of the roof, parasitic treatment of the frames;
• Replacement or repair of the gutter and downspouts;
• Insulation of facades from the outside (pavilions 1920 and 1948);
• Attic insulation;
• Installation of a hygro-adjustable VMC;
• Installation of a gas condensing boiler;
• Upgrading to electrical standards;
• Prose of assistance in climbing steps as needed;
• Doorbell replacement;
• Replacement of gates, gates and mailboxes.

Social economy

Social economy and professional integration :

Both parts of the project called on integration professionals. For the renewal of the district, there are already 7,125 hours of integration through economic activity carried out on new constructions for 19 beneficiaries, including 2 hirings carried out on permanent contracts.
