| ELEMENT DESCRIPTION |
|
| ACCESS FLOORING |
Designed to accommodate 600mm clear depth access flooring throughout technical areas |
|
| ELECTRICAL |
|
| AUTHORITY SUPPLY |
Two (2) 33kV cable feeds from switching station with two(2) 33/11kV transformers
providing n+1 redundancy.
|
| RETICULATION |
11kV cabling reticulated to transformers on each level, arranged in parallel
redundant configuration. Cabling originates from 11kV switchboards connected
to direct diesel coupled rotary UPS systems providing continuous output
for critical loads and short break output for non-critical loads. |
| CAPACITY |
IT power of up to 800 watts/m2 plus power for air-conditioning plant with
cable and transformer capacity for 1000w/m2 on any floor |
| RELIABILITY |
n+1 for all equipment including cable reticulation. |
| UPS AND STANDBY POWER GENERATION SYSTEM |
Provided by direct diesel-backed Piller rotary UPS systems that fully
support the facility under maximum load with combination of continuous
and short break supplies.
|
| GENERATOR FUEL CAPACITY |
48 hours fuel capacity onsite with 24x7 fuel supply contract to be
executed to increase operational time. |
|
| ENVIRONMENT |
Constant 22oC +/- 1oC. Relative humidity 50% +/- 10% at control instruments. |
| HEATING, VENTILATING AND AIR CONDITIONING SYSTEM |
Chilled water produced by water-cooled central chillers in (n+1) configuration,
circulated to down blow process coolers in technical areas. Cooling towers
located in roof plantroom. HVAC System will use non- HCFC refrigerants. |
| HEATING, VENTILATING AND AIR CONDITIONING FEATURES |
On floor chilled water ring main served by three (3) independent risers,
each riser sized for 50% load at maximum capacity. |
| CHILLERS |
Three (3) Trane 4,500 kW
|
| PROCESS COOLER |
Process Coolers are Liebert, or as specified by tenants |
| CHILLER POWER SUPPLY |
6.6 kV high voltage supply to each chiller. |
| CHILLER BACK UP POWER SUPPLY |
Chillers provided with continuous power from diesel-backed rotary UPS
system. |
| REDUNDANCY FEATURES |
n+1 for central chillers and cooling towers. On floor process coolers
to be n+1 as a minimum or a 125% load at maximum capacity. Cooling tower
water storage will have a capacity of 48 hours of operation in the event
of mains failure. Water supply will also incorporate dual connections
to authorities main. |
|
| CABLING SYSTEM |
Carriers permitted to install interior proprietary cabling. Global Switch
managed installations to structured wiring plans and cable management practices. |
|
| FIRE SERVICES |
Three-stage fire detection system that maximises detection
|
| FIRE SPRINKLERS |
Double interlocked pre-action sprinkler system to the technical areas,
conventional wet pipe sprinkler system to the ancillary areas. The double
interlocked pre-action sprinkler system requires a signal from the detection
system and a loss of air pressure in the pipework due to the activation
of a sprinkler before the solenoid valve will activate and charge the pipework
with water. |
| SMOKE DETECTION |
Multi-point aspirated smoke detection system to the technical area and
sub floor. Addressable point type smoke detectors in the ancillary areas.
The multi-point aspirated smoke detection system will have three stages
of alarm.
Stage 1 (alert) - Alert signal to fire affected area and security to prompt
investigation. Stage 2 (pre alarm) - Evacuation sounded in fire-affected
area.
Stage 3 (alarm) - NSWFB is called, gas discharges, detection system signals
pre-action system. |
| GAS SUPPRESSION SYSTEM |
Centrally stored Inergen with risers to each technical space. This allows
tenants to enclose their area and extend the gas pipework to provide local
gas suppression via directional valves. |
| FIRE EXTINGUISHERS |
Fire extinguishers throughout the building with CO2 extinguishers on the
technical floors. |
|
| SECURITY SYSTEMS |
|
| MANNED |
24x7 staffed security.
|
| CCTV |
Full coverage of exterior, entryways, lifts, stairs and site interior
with LCD colour monitor screens. 28-day digital system |
| ACCESS |
Fully staffed security control room. Proximity access control system for
entrance, exit and lifts. All tenanted areas have door access controls. |
| SITE ENTRANCE |
Entrance barriers controlling vehicle entry. Personnel access through
revolving access doors via a security personnel trap |
| ALARM SYSTEMS |
Intrusion detection alarms will include perimeter and internal door sensors,
glass breakage sensors and motion detectors for CCTV interlock. |
|
| WATER SUPPLY |
Dual cold water connections from the authorities’ mains in Harris
Street and Quarry Street |
| COOLING TOWER WATER SUPPLY |
A separate cooling tower water supply with feeds from the primary water
supply and from the secondary supply consisting of a water storage tank
that will have a capacity of 12 hours of operation in the event of the failure
of both mains. |
|
| BUILDING ACCESS |
|
| DELIVERY |
Articulated truck access to delivery zone. Loading bay, goods lift with10,000kg
capacity to all technical floors, secure storage area, staging area. |
| PASSENGER LIFTS |
2 x 2000kg – 30 person passenger lifts that serves all technical
floors |
