A disaster is always unexpected.


On 4 September 2014, there was an explosion at the Beukenhorst apartment complex in Diemen. Two people died. 15 people were injured, and more than 200 residents were affected because their homes were uninhabitable for an extended period. Woonstichting De Key was hit by a serious and extensive claim for damages.

Woonstichting De Key is a housing corporation with over 30,000 rental housing units in Amsterdam, Diemen and Zandvoort. Together with his department, Business Bureau Manager John Haakman is responsible for providing the organisation with various aspects of support and advice. The business bureau is responsible for disaster management at De Key and for contract management, which also includes managing insurance contracts. De Key and Raetsheren have worked together for a long time in the field of risk management.


John Haakman has worked for more than 30 years with De Key, an organisation with over 300 employees. “A well loved colleague died in the explosion. She had also worked at De Key for a long time and everyone knew her, but at that moment we had no time to mourn. We had to act quick and effectively to get everything sorted out.

From the start, Raetsheren worked with us as our partner. In consultation, we called in expert advice and considered the possibilities regarding the engagement of opposing expertise. Together with Raetsheren, we prepared in our role as housing corporation for claims from residents and organisations. Periodic consultation was therefore quickly established. A disaster always comes unexpectedly, and you try to make preparations as well as possible in the ‘cold phase’, but you can never prepare for such a big and serious event.”

Peter de Koning is Claims Manager at Raetsheren. “Right from the start, De Key did everything possible to limit the problems arising from the explosion for residents to a minimum. Thy organised temporary accommodation for affected residents, and in many cases long-term housing, in order to help the residents through this difficult period as much as possible.”

After the disaster, De Key interviewed those involved with a view to improving the disaster plan and maximising preparedness.
