Collapsed quay wall Amsterdam was cordoned off last month due to subsidence

The quay wall in Amsterdam, which partially collapsed on Tuesday, had already been sealed off as a precaution due to subsidence in the paving. The University of Amsterdam (UvA) had had the pavement renewed in May and in August part of it sagged. An investigation into the cause was still in progress, reports the UvA.

The building adjacent to the quay houses various UvA training courses and services. After the piece of quay wall near the Grimburgwal collapsed, the building was evacuated. Another university building on the quay was also cleared.

Keep an eye on

The quay wall is strutted. In the next few days the condition of the two UvA buildings on the quay will be monitored. In any case, the buildings will remain closed for the rest of the week. Employees can go in with security guards to collect things, reports NH Nieuws. Education is given elsewhere.

What caused the quay wall to collapse is still being investigated. It cannot be said with certainty that the subsidence in the paving and the collapse of the wall are related, “but that could well be,” says a spokesman for the UvA.

Alderman Sharon Dijksma previously announced that the collapse is being investigated for overdue maintenance. “Probably a sinkhole,” she said. With such a sinkhole, a lot of water suddenly flushes away, for example due to heavy rain or a rupture in the water pipe, which also involves soil.

Overdue maintenance

Many bridges and quay walls in Amsterdam are in bad shape. Dijksma: “We have done too little maintenance in recent decades An external study commissioned by the municipality last year showed that the city had been systematically spending too little money on maintenance since the 1980s.

Overdue maintenance will have to be tackled in the coming years, but it will still take some time before everything is back in good condition. “We have about 200 kilometres of quay wall to investigate, and more than 800 bridges,” says Dijksma.
