Telecommunication Satellite Facility Adelaide – UPS Capacity Upgrade
Ryan Wilks completed the full electrical and mechanical design & construction of this Uninterrupted Power System at a critical site in Adelaide. The project was completed remotely from the Sydney branch during the height of the COVID-19 Global Pandemic and associated national and international border travel restrictions, with practical completion and final load migration completed ahead of schedule.
The new UPS system has been installed in a vacant old EPG Room. This vacant room enabled the installation and commissioning of the new system ahead of the load migration of all final new and existing and associated critical business loads.
High praise was received from this global telecommunications provider for the team’s positivity and quality project delivery during these difficult pandemic times.
Building Works Summary
- The relocation of storage spares and storage racking from the old generator plant room
- FRL of 120/120/120 fire rating of the external walls to achieve fire separation under the DTS provisions of the BCA for this new battery and power room.
- Replacement of existing external door with a fire rated door and frame to achieve a fire rating of -/120/30.
- To achieve compliance with C2.12 all new penetrations through fire rated walls have been suitably treated, using tested systems to maintain the existing 120/120/120 fire separation.
Fire Detection Summary
Given the criticality of the facility, the building requires fire detection throughout. As the system is monitored by the fire brigade, full coverage to AS1670.1 is maintained as part of the SAMFS conditions of connection. On this basis the following works were completed:
- Decommissioning of the existing pre-action sprinkler system within the old generator plant room.
- Supply, installation and commissioning of new VESDA aspirated detection system within the UPS room compliant with AS1670.1.
- Updating fire alarm block plans to suit the new and decommissioned system.
Mechanical Summary
- Design and installation of new UPS Room cooling system and the supply of 2 x Liebert PCW PH025 Chilled Water Cooled CRAC Units (PCW). These are downflow units which provide direct cooling to the UPS system and ambient cooling in the UPS room.
- Chilled water modification works.
- Battery room exhaust ventilation.
- Full load and site acceptance testing of the cooling and ventilation system.
Electrical Summary
