The subcontracts are on the Balmedie to Tipperty section of the £745m Aberdeen Western Peripheral Route
The latest tranche is in addition to more than £121m of subcontracts already advertised since August, including drainage works, plant and equipment hire, earthworks, steel reinforcement and rock crushing and screening.
Transport Minister Keith Brown said: “These significant subcontract opportunities mark the final steps prior to the construction of the Aberdeen Western Peripheral Route / Balmedie-Tipperty scheme. In the coming weeks, another £70m in subcontracts will be advertised through Public Contracts Scotland, with a further £30m to be advertised in the coming months, bringing the total package to £221m.”
He added: “Preparatory work on Aberdeen bypass is nearing completion with full construction due to start shortly. Work on new road improvements at Inveramsay Bridge on the A96 is moving apace, and I will be visiting Aberdeen tomorrow to see for myself ground investigation work start on the notorious bottleneck at Haudagain roundabout. This vital preparation work is essential to ensure we are ready to start work when the Aberdeen bypass is finished, and forms an impressive package of transport infrastructure improvements we are delivering for the north east.”
The project is being delivered in partnership by Transport Scotland, Aberdeen City Council and Aberdeenshire Council and is being procured under the Scottish government's non-profit distribution (NPD) model.
Main contractor is the Connect Roads consortium of Balfour Beatty, Carillion and Galliford Try (Morrison Construction).
