Metronet has drafted in a programme management expert from Bechtel to review its problem tube station contracts.

It is understood that John Gaudette, formerly of engineers Bechtel and Jacobs, was appointed 鈥渧ice president, stations鈥� of the tube consortium about a month ago and is looking at how the remainder of the works can be delivered.

Metronet is responsible for maintaining and upgrading two-thirds of the London Underground network, but went into administration in July. The stations work has been the most problematic part of its contract.

A consultant involved with the consortium said: 鈥淭he station delivery project needs serious reform and John is very much a big programme delivery guy.鈥�
