Tunnel collapse probe begins

News

INVESTIGATORS ARE considering whether the collapse of a tunnel entrance in Doncaster last week was caused by the failure of two 25m span precast concrete roof beams.

A construction worker was injured as sections of roof gave way beneath the Frenchgate shopping centre development in Doncaster town centre last Thursday.

The collapse occurred as workers raised a concrete beam by 50mm at the £200M site.

The tunnel is one of two carrying traffic underneath the shopping centre, which is being refurbished and extended.

The incident happened in the northbound tunnel, but the parallel southbound link was also closed after the collapse.

A spokesman for developer Scarborough Development Group said consultant Arup had 'undertaken a thorough structural inspection of the incident site - and declared that both tunnels are entirely structurally sound'.

He added that contractor Sir Robert McAlpine was co-operating fully with the Health & Safety Executive investigation.

The development, due for completion next year, also involves combining a 30 bay bus station and a railway station on one site.
