São Paulo Diary: Fresh Bubbling Newsflow From the Pinheiros Smoking Hole Watch

Erro em túneis não atrasará obras da Linha 4, diz Consórcio: “Error in Line 4 tunneling will not delay work, says consortium.”

Earlier this year, a smoking hole opened up in the earth at the excavations for the future Pinheiros station on the Yellow Line extension to the São Paulo Metrô subway system.

It looked an awful lot like a small meteor strike.

This took place in our general neighborhood, by the way. The governor also lives around here, and the federal Treasury minister reputedly has an apartment right up the hill here.

As the “big armadillo” excavator has continued to dig, the foam used to lubricate the bit has tended to bubble up to the surface.

Which is why this desencontro — two tunnel segments failed to meet by a bit less than a meter, which actually does not seem like a major margin of error, on the face of it — is news.

I wish somebody would interview an engineer about whether this error really is within acceptable margins or not.

Comments the Mrs., somewhat obscenely, on the item, which she notices at just the same moment I do:

Eu não vou pegar essa Linha Amarela nem fodendo.

To the fresh, bubbling newsflow:

Frentes de trabalho das obras da Linha 4 se desencontraram em 80 cm. Consórcio Via Amarela afirma que problema não vai provocar atrasos.

Two excavation fronts on Line 4 fail to match up by 80 cm. The Yellow Line Consortium says the problem will not cause delays.

Know who is in charge of New Projects, I believe it is, for the Metrô authority here?

The mayor’s brother.

Who is a construction contractor.

You never see the local press remarking on that curious fact. That I have seen.

O encontro entre duas frentes de trabalho nas obras da Linha 4 (amarela) do Metrô de São Paulo ficou prejudicado por um desalinhamento horizontal de 80 cm entre as escavações. O erro ocorreu no local em que deveriam se conectar os túneis construídos por operários que trabalham nas frentes de trabalho denominadas Caxingui e Três Poderes, na Zona Oeste.

The junction of two segments on the Yellow Line were harmed by a horizontal displacement of 80 cm between the two excavations. The error occurred in the location where the two tunnels, being built by workers on the so-called Caxingui and Três Poderes segments, in the Western Zone,

Segundo o Consórcio Via Amarela, responsável pela obra, a correção da falha não atrasará a entrega das obras. Em nota divulgada nesta quarta-feira (19), o consórcio diz que o erro “não gera qualquer alteração no prazo, custo ou segurança das obras” e que a “correção geométrica ocorrerá na seqüência dos trabalhos.”

According to the Yellow Line Consortium, which is responsible for the project, correcting the flaw will not delay its delivery of the project. In a press release issued today, the Consortium said the error “is not creating any change in the deadline, cost or safety of the project” and that “the geometric correction will be made in the normal order of work.”

Ainda em nota, o Via Amarela diz que “é absolutamente normal que haja um pequeno desalinhamento no encontro de túneis.”

It also says that “it is absolutely normal for there to be a small misalignment at the junction of two tunnels.”

Procuracada pelo G1, a assessoria do Metrô informou até as 9h30 não tinha um posicionamento oficial sobre o assunto.

Sought out by G1 (Globo online news portal), the press office of the Metrô authority said it has no position on the matter.

It is not backing the Consortium?

That, cynics say, would be a first.

 

That kilometers of tunnel would miss one another by 80 cm does not seem like the end of the world, of course. But then I am not a civil engineer. Has anyone interviewed one yet? Someone not working for one of the parties to the contract?

Nesta quarta-feira (19), às 21h, a Rua dos Pinheiros, sob a qual é realizada parte das obras da Linha 4, será interditada pela Companhia de Engenharia de Tráfego (CET) a pedido do Consórcio Via Amarela.

Today at 9 pm, Pinheiros Street, underneath which part of the work is being done, will be closed by the state traffic engineering company (CET) at the request of the Consortium.

O objetivo da interdição seria a realização de procedimentos operacionais na obra do local. Em nota, o Consórcio Via Amarela afirma que solicitou à CET a interdição do trecho final da Rua dos Pinheiros para passagem do shield, uma máquina perfuradora conhecida como megatatuzão. A medida é de caráter preventivo, de acordo com o consórcio, devido à presença de edificações antigas e da qualidade do solo local.

The objective of this closure will be to conduct operational procedures at the location.

That is, they will

carry out the realization of operative operational field operations  to implement procedures designed to further advance toward the practical completion, through concrete work activities, of the projected project end-state, using ways and means designed and planned in advance to accomplish end goals as specified by contractual provisions bearing on final delivery conditions that deal with the project in its projected completed state.

In a press release, the Yellow Line Consortium acknowledges it asked the CET to close the final Pinheiros Street segment so that the “shield” [in English in the original –Ed.], an excavator also known as the “Mega-Big Armadillo,” can pass underneath. The measure is of a preventive nature, the Consortium says, due to the presence of older buildings and the quality of the local soil.

The question of why the line did not go “old-school Chicago elevated” in the first place, rather than subterranean, homesick, and blue, in an area that until the 1970s was the bed of a lazy, serpentine Jurassic river, is an interesting one. Anyone?

A interdição será a segunda em pouco mais de um mês. No início de agosto, a Rua dos Pinheiros foi fechada entre as ruas Mourato Coelho e Mateus Grou por causa da abertura de um buraco no meio da pista.

The closure will be the second is just over a month. In early August, the street was closed between Mourato Coelho and Mateus Grou because a sinkhole open in the middle of the roadway.

No, actually it was multiple sinkholes, as I understand it from watching local news. See video segment, above.

O Metrô disse na época que houve uma acomodação do terreno por conta do reinício da operação do megatatuzão e o asfalto cedeu. A Rua dos Pinheiros é um dos trechos por onde vai passar a Linha 4.

The Metrô authority said at the time that there was settling of the terrain because of renewing excavation by the “Mega-Big Armadillo” and the asphalt gave way. …

Most press outlets have just been calling it the “Big Armadillo,” I think.

If more things go horribly wrong, it might be fun to to start naming it after a massively destructive creature from a Japanese rubber-monster movie.

Who was that rocket-powered, revolving, outer-space voyaging mega-turtle again?

Gamera?

O caso trouxe à tona os problemas com a obra. Em janeiro, sete pessoas morreram com a abertura de uma cratera no canteiro de obras da Estação Pinheiros. Em fevereiro, um laudo apontou possíveis falhas nas soldas da estrutura metálica da Estação Fradique Coutinho, que fica na Rua dos Pinheiros.

The case brought problems with the project to the surface.

Literally.

In January, 7 persons died when a [giant smoking hole] opened up at a construction yard at the Pinheiros Station. In February, a technical report pointed to possible failure in the welding of the metal structure at the Fradique Coutinho station on Pinheiros Street.

Rocket-powered. Fire-breathing. Subway-car devouring. An 80cm mismatch may not be enough to start comparing the “Mega-Big Armadillo” to Japanese rubber supermonsters, but if any more smoking holes appear, I, for one, am ready to sic Godzilla on the Consortium. And I think I speak for quite a few of my Lusophone neighbors, too.
