HEATHER HOUSE, ST MARY’S HEALTH CAMPUS, CORK
MURPHY & KELLY DELIVERS HEAVILY SERVICED 60-BED COMMUNITY NURSING UNIT FOR ST MARY’S HEALTHCARE CAMPUS IN CORK… MECHANICAL SERVICES CONTRACTOR
M echanical services contractor Murphy & Kelly (Thomastown) Ltd delivered a rapid mechanical services installation for a 60-bed community nursing unit (CNU) at St Mary’s healthcare campus, Cork. The newly built CNU, Heather House, provides both long and short stay accommodation for Co. Cork’s older residents. The building was expedited as part of the HSE’s emergency Covid-19 works. Mechanical services installation consisted of the complete installation of water services, soils and waste drainage, air source heat pumps, gas boilers, gas water heaters, buffer vessels, mechanical heat recovery, air conditioning, M&E coordination and BMS controls.
The heating system is fed by two heat pumps into a buffer vessel with two gas boilers as backup also into a buffer. The two heat pumps run in a duty standby arrangement. Each room has a digital thermostat with temperatures controlled by Modbus from the BMS system. Control of the heating via the LST radiators is through pressure independent control valves (PICVs) which are controlled by the addressable thermostat. Two gas fired water heaters feed the domestic hot water requirements, assisting the heat pump preheat buffer. Each of the 60 bedrooms has a handbasin and also its own ensuite shower, basin and WC which is serviced by a Mitsubishi Lossnay heat recovery unit. Murphy & Kelly is a family-owned, highly-
skilled and well-resourced mechanical contractor with almost 40 years’ experience servicing large and small projects throughout Ireland. Commenting on the project at St Mary’s CNU, Contracts Director, Dean Kelly said, “We worked closely with the main contractor MMD Construction and the M&E consultants Semple & McKillop on this design & build project to deliver a tight programme of works within six months.” Complying with Covid-19 regulations meant the site team was split in order to mitigate against outbreaks. “We kept the crews completely separate,” said Dean. “They ate their lunch separately, had separate materials storage facilities
“It’s a building that we’re proud to have been involved in.”
