The secretary of Metropolitan Transport of the state of São Paulo, Paulo Galli, said, in a press conference this Wednesday (2), that the central lane of Marginal Tietê in the stretch that collapsed on Tuesday (1st), can be released until the 11th of February.
“At the meeting, the construction company brought two scenarios as solutions: providing for the placement of piles to contain the Marginal lane, it would be ready on the 11th for normal traffic. Today they will position whether you will need this staking, if you don’t need it, in two, three days it would be ready,” she said.
The secretary also announced that an Executive Committee was created, formed by STM (Metrô, CPTM), Infrastructure and Environment, Sabesp, Cetesb, DAAE, Municipality of SP (CET, Infrastructure and Works and Civil Defense).
According to Benedito Braga, president of Sabesp, a collector to drain the tunnels was identified. Thus, sewage in this specific stretch will not affect the Tietê River.
The president of Acciona in Brazil, André Angelo, the company that manages the works on the 6-Orange line, said that 100 people are working at the Marginal Tietê point alone.
Angelo added that the rest of the subway line works are continuing as normal.
During the press conference, it was also informed that the causes are still being studied, but there was no rupture of any structure of the work. According to Acciona, 120 people were working at the scene at the time of the accident.
An Acciona technician also informed the work plan. The well will be backfilled to prevent soil loss; interruption of interceptor flow; filling the cavity with mortar and the application of pile barriers to contain the cavity.
“We placed more than 50 trucks, 30 concrete mixers and 6 pumps to fill the area. It started yesterday afternoon and continues today, with 24 hours of work. As of this morning, we already have more than 3,000 cubic meters of rock thrown into the crater,” said the technician.
According to Governor João Doria, the Municipal Civil Defense concluded that there is no risk for residents of the region and that all costs of recovery will be assumed by Acciona.
