AZ Alkmaar to replace entire stadium roof

Dutch Eredivisie football club AZ Alkmaar has decided to replace the entire roof at its AFAS Stadion after part of it collapsed in the summer.

High winds were blamed for the partial collapse of the roof in the Molenaar stand. The stadium was empty at the time and nobody was hurt in the incident.

AZ Alkmaar said it has now decided to renew the roof above the main stand of the AFAS Stadion.

New research by the engineering company Royal HaskoningDHV has shown that this section of the roof is not designed for downward wind load.

AZ had previously said that three-quarters of the stadium roof would be renewed and that dismantling work started on 1 October.

The club said that in consultation with all parties involved, an assessment is now being made of the period within which work can be started and when it will be completed.

AZ’s CEO Robert Eenhoorn said:

We put the safety of our fans and visitors first and therefore don’t take any risks. That is why we have decided to renew the roof above the main stand as quickly as possible.

In the meantime, a safe solution for the home matches in December is being looked into.

An initial investigation by Royal HaskoningDHV found the roof collapse was caused by a downward wind load on the roof, poorly designed roof connection trusses and thin welds, while the roof structure had been weakened by earlier storms.

AZ is currently playing its home games at ADO Den Haag’s Cars Jeans Stadion.
