ASPENSTUDENTACCOMMODATION, DUBLIN
DELIVERING A COMPLEX MECHANICAL WORKS PACKAGE TO A 10-STOREY ACCOMMODATION BLOCK WAS ALL IN A DAY’S WORK FOR GAFFNEY MECHANICAL SERVICES… MASTERCLASS IN MECHANICAL WORKS
I nstallation of mechanical services to the brand new 365 bedroom student accommodation blocks at Lidl’s Ballymun development in north Dublin, was a mammoth task but it delivered great rewards for Gaffney Mechanical Services. Project Manager, Eamon McKeown at Gaffney Mechanical Services and the rest of the team were tasked with a full supply and install of mechanical works into a congested city site. The package of works consisted of soils and waste, low pressure hot water district heating system, plumbing to communal toilets and kitchens and 365 bedroom pods, Daikin air conditioning units, supply and extract ventilation including fire dampers and fire smoke dampers. Hevac supplied and installed the flue system for the six Hamworthy Wessex
boilers, FG Wilson generator and the Indop 110N CHP unit. They carried out the site visit and agreed routes with the design team to ensure no detrimental effect to building structure. A Tridium Building Management System was installed and commissioned by Ashdown Controls to control all the pumps and valves throughout the building to maintain pressure for the district cold water system. Three plant rooms were installed. One housed six, highly efficient ModuMax gas fired boilers with six circuits feeding the different elements of the building. Heatmerchants supplied all the Grundfos pumps for the distribution of LTHW and DHW circuits to final outlet positions. Grundfos was brought on board and worked in close partnership with the
consultant to ensure most efficient and adequately sized pumps selected for the application. A basement plant room was installed for water storage with all tanks supplied by Tricel. As part of the water services a water softening system and purification plant were also installed and supplied by Environmental Services Ireland. The third plant room consisted of a combined heating and power unit that was installed as the primary energy source with the boiler back up. BUSY SITE Project Manager, Eamon, certainly had his hands full on this busy site. “We had a number of sub-contractors employed on the job,” says Eamon. “Heatec Mechanical Services fromWexford installed a lot of the distribution GB pipework and copper
“It was a great project to be involved with, quite an iconic one within the Ballymun area.”
