PROJECT 47 Another issue here was the fact that some of the boreholes had substantial water yields and diverting the water from the drilling area was challenging. There was also no Eskom electricity on site but luckily, this could be overcome with the use of a generator. “There were no serious challenges, but planning was important,” explains Holden. “The project was simplified thanks to a great deal of assistance by the main construction contractor.” PA LIST OF PROFESSIONALS Project manager John Wicks CIR Construction Contractors Main building CIR Construction HVAC and wet services Reliance Eco Geothermal drilling, testing, and installation of ground-loop system Aqua Earth Product suppliers Heat pump-chiller; FCUs, electronic thermostats, chilled water buffer tank, FCU valves, and actuators AERSA Hot water buffer tanks, gas boiler, distribution manifolds, high temperature and mixing group-sets for all hydronic systems, three-way diversion valves, PLC control system, and HMI Valsir Uneeq Alpin Easy Flat plate solar collectors Solar Energy VS Giga variable speed pumps for FCU supply Wilo www.plumbingafrica.co.za July 2018 Volume 24 I Number 5
