Royal South Hants Hospital – Capital Works Project

The works include the following: air handling unit replacement, provision of packaged hot water plant, water tank replacement, LV Switchboard modifications plus improvements to electrical infrastructure.

Replacement 1 MVA generator, HV switchgear and transformer replacement, improvements to theatres UPS provisions, replacement / reconfiguration of chilled water pumps, new BMS with Trend IQVision head end.

The works also incorporated departmental alterations including the following areas Pharmacy, Audiology, Children’s Services and Toilets.

The works were carried out with the hospital maintaining full functionality. The majority of system shutdowns were carried out on Sundays it being the only day of the week that Operating Theatres were not in use.

A temporary air handling unit was provided to ensure HVAC services were maintained at all critical times with air handling units being replaced in sequence. The air handling units, HTM 03 compliant, were either reconstructed on site from flat pack or provided in sections due to access and space limitations. Each air handling unit was air leakage tested on site.

A 1 MVA temporary generator was provided during the works to allow for bus bar modifications to existing LV Switchboard, upgrade of existing generator from 500 kVA to 1 MVA and allow the HCV Works to be carried out. Mechanical plant and UPS sub-mains cables and distribution equipment were also replaced as were obsolete plug in bus bar tap offs.

The water tanks were replaced sequentially to create potable water and softened water tanks each with division plates to allow continuity of water supply and to ensure all cold water outlets throughout the hospital could be designated drinking water. The water pressure booster sets were also replaced.

3 no. domestic hot water packaged heating units were installed to replace the old buffer calorifier arrangement. These units are fed from the district heating via primary plate heat exchangers and associated pumping and incorporate individual plates and hot water storage which can operate individually or together at peak hot water demand.
