The contract to deliver and look after the Aberdeen bypass has reached financial close at £220M below original estimates.
Aberdeen Roads – consisting of Carillion, Balfour Beatty and Galliford Try – will design, build and operate the Aberdeen Western Peripheral Route for £550M.
The Scottish government said it had estimated the cost at almost £770M before the procurement process began. Quicker and more durable construction techniques have helped to reduce the cost of the project.
Scottish infrastructure secretary Keith Brown said: “I’m delighted the deal to deliver the Aberdeen bypass construction is now sealed.
“Our robust procurement approach has been successful in driving efficiencies in both the long term maintenance operations and the funding of the project.”
Carillion chief executive Richard Howson said: “The project is firmly in line with Carillion’s selective approach to construction, namely of focusing on large, high quality projects, notably those involving integrated solutions.
“We look forward to working closely with Transport Scotland, Aberdeen City Council and Aberdeenshire Council to deliver this major improvement to the transport network around Aberdeen.”
