The decision follows a thorough process of information sharing and was confirmed at a meeting of the Cabinet Office’s Commercial Relationships Board.

It means the private contractor will work with an appointed crown representative as part of the Government’s new approach to monitoring and managing strategic suppliers.

The crown representatives help the Government act as a single customer when engaging suppliers.

Laing O’Rourke joins Amey, Balfour Beatty, Kier and Interserve among its main construction contractor partners, while Atkins, Jacobs and Mott MacDonald feature among its industry consultants.

Laing O’Rourke’s selection as a Strategic Supplier comes as the Government finalises plans to transform investment in vital infrastructure, including the School Rebuilding Programme, the delivery of 40 new hospitals by 2030, new nuclear facilities and rail projects.

These are all sectors in which Laing O’Rourke has a strong track record of delivery.

It has recently completed several new schools in Yorkshire, the Manchester Metrolink and, in November, The Grange University Hospital in South Wales, which was built using modern methods of construction and handed over to the health board four months early and with zero defects.

John O’Connor, group commercial director at Laing O’Rourke, said: “We are delighted to have secured Strategic Supplier status.

“It is exciting news and reflects both the health of our business and our strong track record of delivery using our DfMA led approach.”
