Usiminas Mecânica promotes workshops on bridges and metallic viaducts in São Paulo and Brasília


After an event in Belo Horizonte last June, several workshops have been held with the participation of companies and government agencies

Nearly 50 representatives from 23 companies and government agencies directly responsible for the execution of works in several segments participated in the 2nd Workshop on the manufacture of bridges and steel viaducts. The event was held in São Paulo (SP) on September 21, when the company presented the advantages in the use of metallic structures, Usiminas steel technology and success cases of projects carried out in Brazil and abroad.

The debate was also held in Brasilia, on September 27th, dedicated to Federal Government representatives and consulting companies. There were 38 participants sent by government agencies such as the Ministry of Transport, the National Department of Transport Infrastructure (Dnit), the National Land Transport Agency (ANTT) and Valec, a public company linked to the Ministry of Transport.

These presentations for the market are part of a broad work of Usiminas, developed jointly with Usiminas Mecânica. “We want to spread out the use of steel as an intelligent solution of great contribution to the development of the country. It is necessary to overcome paradigms, to show that we have innovative products, engineering intelligence and much more to promote sustainable development and implementation of innovations in Brazil. The economy is showing signs of recovery for the coming year and we expect the return on investment. This puts us as an option to make infrastructure and industrial projects feasible”, said Usiminas Mecânica's chief executive, Heitor Takaki.

Usiminas Mecânica´s engineer Samuel Lamounier Soares, demonstrated that the use of metallic structures meets the main demands of this segment. “We have very significant results, such as lower weight, special assembly conditions, modularization, larger spans, lower demand for pillars and foundations, shorter execution time and reduction in waste generation at the construction site,” he outlined.

Change of Culture

Among the ongoing discussions was the need to propose a new model for the consultation and bidding of projects for the public sector, with greater openness for the participation of companies during the basic project design phase. “Today, when we receive projects, mainly from the public sector, they are already approved and most of the time already planning the use of concrete,” says Andrade Gutierrez's engineering manager, Paulo Nahass.

Ricardo Duarte project area engineer of São Paulo Roads Department (DER-SP), confirmed the importance of the workshop for that matter. “It is possible to study the feasibility of using steel since the design of projects. This goes through a culture change in engineering that uses concrete a lot. The important thing is to think that metal structures are another option to be considered.”

Innovative Products

In addition to showing the differentials in the manufacture and assembly of bridges and viaducts by Usiminas Mecânica, the development of steel by Usiminas was also highlighted. “As manufacturers, we meet with designers to develop and perfect our products with focus on their applications. Innovation is in the DNA of Usiminas, seen by our Research Center and highly qualified team to propose solutions. That's how we developed high-performance types of steel and better cost-benefit for welding, also used today in the oil and gas, energy and machinery industry, for example,” says Usiminas product specialist Leonardo Turani.

These differentials were outlined by those present as new possibilities for the market. “Currently we have projects in development where we already consider the feasibility of using steel, as seen by the benefits pointed out. We carry out works with the participation of Usiminas Mecânica, such as soccer stadium roofs and we are open to new partnerships. This event contributed a lot in this direction, with massive participation of large companies,” said Eduardo de Moraes, WTorre Group engineering director.
