Create future real estate projects with a unique and sustainable constructive model

GA has developed a unique construction model that combines high build quality and on-time delivery, while guaranteeing energy efficiency and user comfort.

GA uses industrial construction methods to consistently deliver high-quality buildings and ensure deadlines are met. The company’s model ensures that projects remain on schedule and shortens construction lead times by 20 to 30% compared with conventional projects. Implementing unique construction methods and manufacturing exclusive temperature control installations results in projects carried out at a quick pace, with pinpoint precision and limited investment in human and physical capital.

Efficient processes with a proven track record

GA develops exclusive construction processes and manufactures building elements at its industrial sites: two equipment factories and three precast concrete factories on the outskirts of Toulouse, Colmar and Rouen. One key component of GA buildings is the use of Leiga and Tridal frames, which are installed in multi-storey buildings with slabs that are either laid on a post-and-beam system or directly fitted onto the posts. For their part, Intertec frames are manufactured using precast concrete structural elements assembled on-site using mechanical fasteners, which ensure extremely accurate mounting and reduce construction times.
