Pigra is committed to promoting the development of a modern, comfortable, sustainable, efficient and environmentally friendly transportation infrastructure. We have a team of engineers, architects and geologists who develop from the preliminary phase, feasibility studies, projects and specialized annexes, construction management and technical assistance in the execution phase and studies of repair, maintenance and inspection of bridges and crossing works.

At the same time, the development of the linear works, cause the existence of factory works. The knowledge of a wide range of structural solutions, of different materials and of the stages through which a structure passes, allows Pigra to obtain the optimal solution from its conception and design to its rehabilitation and reinforcement, including the study of different types of foundations, pathologies, technical assistance on site and support in research on structures and their materials.
