Administrative receivers have been called in at the Galleria shopping centre in Hatfield by bankers owed £130 million by the project's developers.And that is bad news for subcontractors and management contractor Balfour Beatty, which has a high Court writ outstanding claiming £500,000 in unpaid fees from the developer A1 Gallerias Investment Corporation.Receiver Grant Thornton partner Scott Barnes said: 'Basically any claim from that writ would leave Balfour Beatty as an unsecured creditor with very little chance of getting any money.'Mr Barnes said his team are currently sifting through the centre's financial situation and no figures have yet emerged on how much is owed to contractors or held in retention monies.A Balfour Beatty spokesman said: 'Our exposure in all this is minimal. It is the trade contractors who will suffer because most of that money would have been passed on to them.''This is a small amount in relation to the overall development, but it could hit some subcontractors hard.'Mr Barnes and his team are confident of maintaining the centre as a going concern.The receivers are also looking into other outstanding legal action involving architect Aukett Associates.
