Underground Works
CBNA implemented its groundbreaking innovation capabilities in North America when tunneling through a unique geology with the world’s first hybrid Tunnel Boring Machine (TBM) based on the Water Control Process method.
Proficient in the entire range of construction techniques, we have built our reputation on our ability to deliver iconic structures and to design customized tools and equipment to adapt to the natural constraints of the site.
We are now ready to rise to the challenges of the future: building in dense urban environments, designing floating structures, developing very long span bridges. As a responsible builder, we are constantly improving the durability and optimization of civil engineering structures in order to conserve resources and minimize humankind’s impact on its environment.
