Collapsed ceiling

A ceiling to an external archway to a modern block of flats suddenly occured following high winds. Fortunately no one was hurt.

The ceiling comprised a softwood timber frame supporting a proprietary soffit and was crudely plugged and screwed into the concrete soffit using DIY style rawl plugs and domestic screws.

Over a period of 20 years or so, the rawl plugs had become brittle and the fixings were inadequate to support the weight of the ceiling in addition to the high suction loads from the wind. The wind loads were significant as the site is adjacent to the River Thames and the archways act as funnels, between the large buildings.

We designed a new, more robust ceiling with stainless steel resin fixings and a steel framework, to provide better durability than the timber.
