Pigra Engineering is committed to promote the development of a modern, comfortable, sustainable, effective and environmentally friendly road infrastructure. We rely on our specialised team of engineers, architects and geologists to develop preliminary studies, feasibility studies, specialised designs, site supervisions and technical assistances in construction phases and bridges inspection and reparation.


Development of road infrastructure makes usage of prefabricated structures necessary. Pigra Engineering has the necessary skill set in terms of structural engineering, material knowledge and infrastructures to find optimised solutions from its preliminary design phase to the rehabilitation and renovation phases, including studies for foundations, pathologies and material and structures research.
