Work on the viaduct which has been reduced will take 5 months

The city of São Paulo announced that five months would be the deadline for the completion of the viaduct recovery works in the interconnection of the fast track to Marginal Pinheiros, near the Jaguaré bridge, which has surrendered on November 15th. The total cost will be $ 30 million.

The mayor, Bruno Covas, said that this amount could be repaid in the future by the state government, but that, in principle, the amount would be disbursed by the town hall itself. The company under contract, in case of emergency, was JZ Engenharia e Comércio. "The city council took full responsibility for the social security measures taken in the viaduct," he said.

Causes

The causes of the bridge break were reported by the town hall as a composition of factors. Concrete fatigue and hidden defects (unidentifiable during visual inspection) have been identified, such as the breaking of the middle part of a beam, which has bent and supported on the pillar. "We will reform the pillars, fix the beam and fix the painting," said Vitor Aly, Municipal Secretary of Infrastructure and Public Works.

After the construction of the last day, the secretary noted that the viaduct had uneven wear. "After putting the hydraulic cylinders, we found a non – symmetrical shortening of the plank.On one side, there was a shortening larger than the other.In the initial design, it was for [o tabuleiro] to deform in an equal and symmetrical way, "explained the secretary.

The city government rules out the need to demolish the viaduct because it would take up to three years for a new viaduct to be ready. In addition, a call for tenders would be required and the planned expenses would be R70 million. The mayor pointed out that reports would be prepared to badess the situation of 185 bridges and viaducts in São Paulo, in order to avoid new accidents.
