Testimonies

Recognition of the great names in engineering sector.

We are surprised by the way the company solves the structural problems. We compared our working process with one of the greatest north american companies, on the designing of reinforced concrete elements as well in steel, and came to the conclusion that we are a step ahead of them, which makes us very satisfied.

Dr. Mário FrancoE.T. Julio Kassoy e Mario Franco - São Paulo, SP.

Our designs show today a quality level much higher than before. In every design we perfom simulations, where several alternatives were testes, which it was almost impossible some years ago. Nowadays, the computer that does the most part of the mechanical calculation operations and alows our engineers to be free in their activities and more suitable to their real competency: think and create.

Eng. Vitor Faustino PereiraEstrutural - Londrina, PR.
