SCOTLAND'S PARLIAMENT building is expected to cost close to three times original estimates, project sources said this week.
Latest projections put the cost of the Edinburgh project at £250M, compared with the original March 1998 estimate of £90M. Of this £50M was for construction.
The sum, which includes £20M set against contingencies, has been drawn up following the decision by members of the Scottish parliament in June to remove a £195M cap on project costs.
When site preparation got under way in 1998 the Scottish parliament was predicted to cost £90M in total, but the project has been dogged by cost escalations.
According to chief architect John Gibbons, final construction costs will be £116M. Some £100M of contracts will be let by the end of this month.
The remaining £115M to £135M is accounted for by site acquisition and preparation, fees, services, fit out and VAT.
A principal risk still facing construction is integrating services and glazing, said operations director at construction manager Bovis Lend Lease Alan Mack.
Design of the parliament's debating chamber and support buildings by architects Enric Mirelles and RMJM, and structural engineer Arup, is a complex of angles and planes, presenting some 'difficult' interface issues, said Mack.
