In the coming weeks, another £70m in sub-contracts will be advertised through Public Contracts Scotland, with a further £30m to be advertised in the coming months, bringing the total package to £221m.“These will provide excellent opportunities to get involved in the largest project to be procured using the Scottish Government’s innovative non-profit distributing funding model.”Preparatory work on Aberdeen bypass is nearing completion with full construction due to start shortly.
