The builder will be working as part of the SPACE consortium, which includes Davis Langdon and Fulcrum Infrastructure Group.
This is the first of several hub schemes being piloted by the Scottish Futures Trust to pursue value for money in infrastructure investment.
The first hub project, to get underway later this year, is the £5.7m design and build of a library and community joint facility in west Edinburgh.
The hub initiative resembles the LIFT and BSF programmes in England.
Under the deal, SPACE will team up with the South East hub Territory Board, Councils, NHS Health Boards and the Emergency Services to deliver a whole swathe of building projects.
It is based on a single-point-of-delivery model whereby the private sector consortium takes responsibility for project strategic planning through to project delivery, funding and facilities management via an integrated supply chain.
Greg Fitzgerald, chief executive of Galliford Try, said: “We’re delighted to build on our experience of major public sector partnering schemes through this key role with the South East hub Territory Board in Scotland.”
SPACE beat rivals Alba Community Partnerships (a consortium made up of Cyril Sweett Investment and Miller Corporate Holdings and Robertson Capital Projects) to prized preferred bidder slot.
