A timber-frame housing development under construction in north London burned to the ground in less than nine minutes, a 好色先生TV investigation has revealed.

The findings of a London Fire Brigade (LFB) inquiry into the fire that ripped through the Beaufort Park development in Colindale on 12 July has raised questions about safety procedures on timber-frame developments.

A meeting in December to discuss the findings could lead the Health and Safety Executive to publish new guidance on how firms should protect construction sites from fire.

In an exclusive interview with the LFB, Stephen Robinson, the group manager of the fire engineering department, said little can be done to save half-constructed multistorey timber buildings from total destruction. 鈥淚f an unfinished building like this catches fire, it will spread more quickly than the fire brigade can intervene,鈥� he said.

The fire is understood to have started accidentally in a building consisting of a structural timber frame and roof. It burned rapidly and radiated vast amounts of heat owing to the lack of protective external cladding.

The LFB and other experts have warned that the uncontrolled spread of this fire means a new approach is needed for multistorey timber-framed construction sites.

鈥淲ith timber-framed buildings of this size you need to take a different approach from steel or concrete during construction,鈥� said Peter Bressington, the director of multidisciplinary consultant Arup鈥檚 fire engineering department.

鈥淚f there鈥檚 a fire in a concrete or steel building it wouldn鈥檛 be an issue, but in a timber-framed building you would lose the lot.鈥�

Bressington said it was the Construction (Design and Management) supervisor鈥檚 job to consider risks specific to timber-frame early in the design process and to mitigate these.

He said: 鈥淚f it鈥檚 flagged up that a development is going to be built from timber, it should trigger a process. [The programme] should address the time the building is vulnerable. For example, you should get the fireboarding on as soon as possible. You also need to reduce the fire load and ignition sources on site.鈥�

The HSE said it was 鈥渁ware of the particular health and safety issues during the construction of timber-frame buildings鈥� and was 鈥渨orking with the industry to help them manage these risks鈥�.

Bryan Woodley, chief executive of the UK Timber Frame Association (UKTFA), said there were no special problems with timber-frame construction, noting that 鈥渁ll building methods have their areas of vulnerability鈥�.

But he said the UKTFA was due to meet with the LFB and HSE in early December. 鈥滻f Colindale shows extra measures are needed, we will look at that,鈥� he said.
