GUERNSEY AIRPORT has clocked up more than £10m. in new costs since the development project started in 2009, it has emerged.

The costs are detailed in an appendix to Public Services’ report on the project in this month’s Billet d’Etat – but has been signed off as value for money by Treasury.

It provides a comparison between the development’s budget in 2009 and May’s final estimate.

The costs include a ‘pre-award contingency risk’ of £4.7m., an increase in professional fees from £1.8m. to £5.2m., a £400,000 increase in nose-in, push-back parking for aeroplanes and £3m. allocated for soil treatment provision.

Although negotiations with PSD’s preferred tenderer, Lagan Construction, identified savings of more than £2m. it is unclear why some costs have gone up by so much.
