The cost of the Aberdeen bypass has been driven down by almost £220m over the life of the contract.

The Aberdeen Roads Limited consortium of Balfour Beatty, Carillion and Galliford was named preferred bidder this summer.

The deal has now reached financial close with construction costs on the Aberdeen Western Peripheral Route/Balmedie-Tipperty project also cut by £11m on original estimates.

Cabinet Secretary for Infrastructure, Investment and Cities, Keith Brown said: “While the overall estimated scheme costs remain at £745 million, the contract value, which is around £550 million in net present value terms, is almost £220 million less than the pre-tender estimate and amounts to a reduction in payments over the life of the contract of approximately £26.5 million per year.

“The capital cost of construction also came in under the £472 million estimate, (cost at 2012), by £11 million on a like for like basis.

“Our robust procurement approach has been successful in driving efficiencies in both the long term maintenance operations and the funding of the project.”

The contractor is planning to deliver a more durable ‘long-life’ road, which will reduce the future maintenance requirements.

The shortened construction schedule, with project completion now due in winter 2017, has also helped to keep building costs to a minimum.

Work will start immediately and the project includes designing and constructing 58 kilometres of new dual carriageway.

The contract also includes constructing 40 kilometres of new side roads, 30 kilometres of access tracks and more than 100 new structures, including two significant focal point bridges over the rivers Dee and Don.
