Railway bridge – Grand Paris Line 18

Scope of Works

Detailed design for precast special bridges with integrated BIM LOD 400 for shop drawing production;
High-precision modelling of rebars and prestressing tendons to meet strict structural detailing standards.

Grand Paris Express – Line 18 is a 35 km fully automated metro line and a key component of the major expansion of the Paris transit network. It connects Orly Airport to Versailles Chantiers, passing through strategic areas such as Massy-Palaiseau and Plateau de Saclay.

Currently under construction, the project is expected to be completed in phases between 2026 and 2030, aiming to improve connectivity across the Île-de-France region and support both economic and scientific development.

We contributed to the project by producing rebar detailing for precast segments of special bridges, including RN118, RD36, and Aqueduc.
