Dome expert for Montreal roof investigation

MILLENNIUM DOME engineer Ian Liddell is in Montreal after being commissioned to advise on the Olympic Stadium's failed fabric roof.

Five people setting up a motor show were hurt by snow and slush when a 350m2 panel failed on 18 January (NCE 28 January). Dome designer Buro Happold confirmed that Liddell will use his expertise of tensile structures to investigate the cause of the accident.

But the consultant denied that the cladding fabric used on the ill-fated Montreal roof was the same grade to that on the Dome. Suspicion had been growing that the Millennium Dome had been constructed using fabric diverted from Montreal, following allegations by US-based

roof installation contractor, Danny's Construction.

Work on Montreal's £23M roof was well behind schedule, with heat welding of the sealing flaps at panel joints suspended until spring and sections of the perimeter unfinished.

Danny's was suing fabric supplier Birdair for £2.5M after being thrown off site last October. It had claimed the main reason for the delays was that Birdair was diverting the Teflon-coated glass fibre fabric to another project.

But Buro Happold confirmed that the fabric at Montreal is a lower grade material, with a tensile strength nearly 40% below that used on the Greenwich structure.
