The work has seen LST install nine-tonne ‘transformer housing’ to the hospital’s roof, along with a similar-sized low voltage panel and ring main units. The equipment will improve the operating capability of the hospital’s chillers and the quality and level of air conditioning for operating theatres.
In conjunction with the works on the roof, a new substation has been constructed at ground level to serve the new equipment. This has required high voltage cables to be installed through seven floors of the hospital and across the roof.
To increase power at the south side of the hospital, a building has been constructed to house a new mains switch panel. Low voltage cables have been installed through ceiling voids in live areas across four floors and into a main plant room in the neurological department.
The project has required LST to manage large crane lifts as well as associated groundworks in preparation for the equipment. A 500-tonne crane was used to lift the chillers onto the roof of the seven-storey building and a 300-tonne unit was needed to lift the secondary items, including huge cable drums and other materials for the associated works.
Justin Horton, Site Manager at LST, said: “This contract builds on our long-established relationship with University Hospital Southampton (UHS) and required specialist experience and expertise.
“It was a very challenging project requiring specialist electrical works and many logistical considerations. Stringent management, co-ordination and communication were key to minimise disruption for the hospital’s staff and patients.”
LST has delivered a wide range of construction projects for UHS in recent years, including the expansion of an eye unit, the construction of a new cancer care facility and an extension to Southampton General Hospital’s north wing.
