Work can continue on 300m London tower after Judge rules that site vibration levels are acceptable

Work will continue working on the Pinnacle tower in London after a judge postponed a ruling on vibration levels.

Insurance company Hiscox had claimed that contractors had flouted vibration levels on four occasions in the last four weeks.

Hiscox lodged a claim with the High Court to impose absolute levels of vibration on developer Arab Investments and subcontractor Keltbray, sparking fears demolition would have to be restricted or halted.

At a hearing yesterday the court refused an application by Hiscox to impose interim limits until the full case is heard in January.

The court also refused to grant an injunction for water damage, but upheld one for site access. The companies must allow regular access to the Hiscox office at 1 Great St Helen's or face contempt of court.

The Pinnacle, also known as the Helter Skelter, was granted planning permission in February 2007 and is set to be the tallest tower in the City of London.
