The £30m facility, expected to be ready by late 2018, will have 74 acute mental health ensuite bedrooms including six psychiatric intensive care beds.
Northern Ireland health minister Michelle O’Neill cut the first sod at a ground breaking ceremony.
“Graham-BAM Healthcare Partnership is delighted to be working with the Belfast Health & Social Care Trust in the delivery of this impressive new facility, which will bring consolidation, modernisation and centralisation of acute mental health care inpatient services to the community of Greater Belfast,” said director Peter Reavey.
The contracting joint venture is currently delivering a £185m four-year framework at the Ulster Hospital. A seven storey, 30,000m2 inpatient ward block will open to patients in the new year and work has just begun on a new 31,000m2 acute services block, which is expected to complete in summer 2019.
