The redevelopment of the hospital site was undertaken in partnership with hub South East Scotland, which has been involved from the initial stages of master planning, and main building contractor for phase one Morrison Construction.

Preparations are underway to start a rolling programme of service relocations to the new facilities and will see staff moving into their new surroundings throughout the first half of 2017.

Phase one of the campus redevelopment includes the Royal Edinburgh Building, a facility providing services for the adult acute mental health inpatient service, older people’s mental health assessment unit, Intensive Psychiatric Care Service (IPCU) and the new Robert Fergusson national brain injury unit.

Professor Alex McMahon, chair of the Royal Edinburgh Hospital campus project board, NHS Lothian, said: “We are delighted that we now have the keys to the new buildings.

“A lot of hard work has gone into reaching this important stage in the project and, while we are not yet at a stage to moving services into the buildings, it does represent a significant milestone in the Royal Edinburgh Hospital campus redevelopment.

“Throughout this process we have involved, listened to and taken on board the views of patients, staff and the public and we are confident that these new facilities will provide excellent mental healthcare to adults and older people in Lothian.

Jo Elliot, chair of hub South East Scotland, said: “I am delighted to mark the handover of Hub South East’s first revenue funded health facilities and largest completed project to date.

“Hub’s involvement from the beginning, helped shape the plans for this campus redevelopment and it’s exciting to be able to tour the new facilities and see the modern spaces patients and staff will soon be using. It’s also with great pride that we can demonstrate a range of community benefits, from supporting thirty apprentices and thirty seven new jobs during construction, to awarding 94 per cent of work packages to Scottish SMEs.

“One of the factors to the successful delivery of this project, delivered on time and on budget, was the relationship between ourselves, our supply chain and our client, NHS Lothian. We look forward to continuing this excellent working relationship as we further develop future phases of the campus together.”

David Wilson, operations director for Morrison Construction, added: “Morrison Construction was appointed by hub South East and NHS Lothian to deliver the new Royal Edinburgh Hospital campus phase one and we are delighted to have fulfilled this goal.

“The new hospital is a first class facility and will transform and enhance healthcare for patients and staff and I very much look forward to seeing the hospital campus up-and-running and welcoming patients in 2017.

“Morrison is proud to have played a part in this project and we look forward to working with all stakeholders on future phases of this significant development.”

The redevelopment of the rest of the campus is planned in two more phased stages, subject to full business case approval and financial close. Phase two will include a new Integrated Rehabilitation Facility, a newly refurbished MacKinnon House and a new Facilities Management Centre.
