Electrical General
The Gold Coast hospital was been located on the present site for more than 50 years. The
site consists of three main buildings – Tower Block, Block D (Rehabilitation) and Mental
Health building. Numerous other smaller buildings also are present on the site.
The Tower Block electrical services were refurbished in 1998. The Mental Health building
was built in approx 1991 with major reburbishments to parts of the electrical installation in
1999 to 2000. The Rehabilitation building or block D is the most recently constructed
building which was built in 2001.

Substation and Incoming Energex Supplies
The hospital complex is supplied with electricity from the Energex 11 kV network and is
connected to three feeders from the Southport distribution subststation. The Southport
distribution substation is in turn connected to a 110 kV ring system and can draw power from
either the Surfers Paradise or Ashmore 110 kV substations. Separate 11 kv to 415 volt
substations are provided in the hospital complex for The Tower Block, Block D and the Mental
Health Building. Each of these substations can be connected to one or two 11 kV feeders from
the Southport distribution substation.
The Tower Block substation comprises three 1500 kVA transformers which can be supplied
from either one of the two incoming 11 kV feeders. An automatic high voltage transfer switch is
provided to switch to the alternate feeder in the event of a feeder failure.
DE
Block D and the Mental Health building have single transformer substations with 11 kV ring main
switches to enable manual switching to alternate backup incoming 11 KV supplies. Both of
these substations are sized to accept an additional transformer if required by future expansion.
The 11 kV supplies to the Mental Health and Tower Block are reticulated in underground cabling
The block D substation is connected to an underground feeder and a feeder which comprises
both underground and overhead reticulation.
The arrangement of substations and high voltage reticulation is considered sufficiently reliable
and no changes are recommended. The following electrical sketch ESK01 is based on
information provided by Energex and details the present arrangement of substations and 11 kV
feeders.

Tower Block – Electrical Installation
3.1
General
The Tower block was constructed in stages comprising part A and part B/C. While both stages
were refurbished in 1998, part A includes some older electrical equipment more than 20 years
old. Lifts were also 1997. The main switchboard and substation were upgraded in 2006. The
cardiac catheter laboratory on level 9 has also been recently completed.
3.2
Electrical Reticulation
DE
The electrical reticulation consists of the following:
• Three 1500 kVA transformers supplying a load of maximum demand of approximately
2600 kVA in summer with all chillers operating.
• Main switchboard located on the lower ground floor within a fire rated room and
comprises metalclad combination switchfuse units in the older section and circuit
breaker protection in the new section
• At the main switchboard lighting, general power, fire services, lifts 2, 3, 7 and 8 are
connected to transformers No 1 and 2. A low voltage bustie switch enables the total load
of transformers No 1 and No 2 to be transferred to a single transformer in the event of a
failure. Total load on these two transformers is less 50% which enables all loads to
operated on one transformer.
• Mechanical air conditioning loads, lifts No 1, 4, 5 and 8 and essential ventilation are

connected to transformer No 3. Transformer No 3 is fully loaded in summer when all
chiller plant is operating.
Automatic transfer switches connect the essential loads to the standby generator should
the normal power be not available.
The low load chiller No. 4 can be connected to the standby generator power supply.
MIMS and fire rated polymer submain cables distribute power to essential ventilation
and lift services.
Metal clad distribution switchboards are located in plant rooms and fire rated or non
combustible riser cupboards.
MIMS reticulation of 240v AC wiring for emergency lighting.
Connection points are provided for the connection of temporary generators to power non
essential loads in the event of a long term outage.
The electrical protection system throughout the hospital is also a concern. Unlike modern
hospital electrical designs the protection system is not discriminating for all types of faults. The
existing system comprises generally fuses to protect submains cables with downstream
subcircuit protection comprising non current limiting circuit breakers. With this combination it is
not possible to isolate subcircuit faults in all instances with the chance that a minor short circuit
fault on a distribution switchboard could blow the submains protection and affect numerous
other circuits connected to the same switchboard.
Subcircuit protection on lighting and power distribution switchboards in block A are
Westinghouse E frame circuit breakers in the order of 30 years old. These are not longer
available. Replacement circuit breakers are available but are relatively expensive. It is
considered more practical to replace circuit breakers and switchboard chassis with DIN style
miniature circuit breakers which are current limiting type and of suitable fault rating. All
distribution switchboards in sections A, B and C of the building have minimal RCD protection of
socket outlet circuits.
Existing switchboard chassis do not permit safe online connection of new circuits. Recent
advances in switchboard chassis provide fully insulated assemblies with switched busbar tee
offs which permit new circuits to be safely connected without load disruption.
The following recommendations are made for upgrading the electrical reticulation in the Tower
Block:
•
•
Distribution switchboards in part A of the Tower Block be replaced and distribution
switchboards in sections A, B and C are upgraded with RCD protection for all general
socket outlets circuits for office, kitchenette, cleaners, etc
Selection of new circuit breakers should be based on a fully discriminating protection
design which prevents short circuits on minor sub circuits blowing fuses which feed
multiple floors of the Hospital.
Replacement switchboards should incorporate circuit breaker chassis which enable online connection of new circuits to minimise hospital operations.

3.3
Standby Generator System
The standby generator system for the Tower Block compises two Detroit Diesel enginees
coupled to Newage Stamford alternators.with a rating of 750 kVA/ 600 kW. Generators are
located in a fire rated room on the lower ground level and were in stalled in 1997. The
generators have facilities to parallel with the output of transformer No 3 for load testing.
Loads connected to the generator include essential ventilation, lifts, air compressors,
emergency lighting and essential lighting and general power and the low load chiller No 4. The
generators have the capacity to operate existing essential loads and the low load chiller No 4.
The protection provided on the generator is comprehensive and includes under and over voltage
protection for the load.
Exhaust from the generators is piped to the original boiler flues which rise to the top of the
Tower Block. Access to the exhaust stacks for maintenance is not possible and future repair
works when required will be costly.
DE
Standby generators in the Tower Block and block D are served by a 20,000 litre underground
fuel storage tank (permatank) with dual wall construction and monitoring.
The standby generator system is considered to be in reasonable condition.
3.4
Lighting
Lighting throughout is generally fluorescent 36watt triphoshor lamps installed in recessed
troffers with prismatic diffusers. Lighting in wards is either recessed troffers with prismatic
diffusers or bed head lighting. Lighting birthing suites, ICU , HDU and recovery consists of
recessed troffers and medical examination pendants.
RTI Folio No. 5
-6-
Lighting in general wards is of lower a standard than current practice. A lighting upgrade of
wards on levels 4 to 9 is recommended. Consideration should be given to providing
additional general lighting, recessed medical inspection lights for each bed and night
lighting. Lighting in theatres is of recent design and considered satisfactory.
It appears that existing lighting does not have toxic PCB type power factor correction
capacitors as earlier buildings do, however in any refurbishment it would be prudent to
confirm this prior to reuse or removal of existing luminaries.

Emergency Lighting
General Emergency lighting within stairwells, corridors and larger spaces comprises a mixture of
a central battery emergency lighting system and single point stand alone units with integral
batteries. The central system was installed originally and single point lights have been added
more recently. Reticulation cabling for the central system is fire rated and uses MIMS cabling. A
dedicated UPS and battery room for the 240volt systems is located on the lower ground level.
Construction of the battery room appears to be fire rated as required by the latest building codes
and standards.
The central emergency lighting system is in reasonable condition. The calculated capacity
based on a 2 hour discharge with the existing batteries is approx 9400 watts of load which
appears sufficient capacity for the Tower Block. The battery recharge capacity is up to 30 amp
which will permit compliance with the 16 hour recharge time of the standard AS 2293.1.
DE
Non Compliance Aspects of the Central System are as follows:
• The switchboards in part B and C have three phase monitoring of local lighting circuits,
however part A of the Tower Block does not have three phase monitoring as required by
the code.
• The Master test switch for the central UPS does not automatically reset as required by
the standard AS 2293.1- part 3.
• Many Emergency Exit signs in part A of the Tower Block have green on white lettering
which is non compliant and have not been available for approx 15 years.
The disadvantages of the central battery system are that the cabling is fire rated and the system
does not have central monitoring system which is available for single point systems and aids in
maintenance. A further disadvantage of the central system is full testing requires discharge of
the central battery. This will remove all emergency lighting from the hospital until batteries are
recharged. With a computer based single point system testing can be carried out in sections so
that some emergency lighting is always available and non 24 hour operations are tested outside
of normal hours. Single point systems with central Stanilite monitoring have been installed in the
more recently built Block D.

Within the last five years the use of RCD protection of general socket outlets has become
normal practice. Since the majority of the Tower Block electrical installation was installed more
approximately 9 years ago RCD protection is restricted to medical areas and wards where
compliance with AS3003 only (body protection and cardiac protection) is provided. Many
general use socket outlets are connected to circuits without residual current protection (RCD).

Socket outlets in the operating theatres comprise four service panels with 4 socket outlets each.
Each panel is connected to a separate RCD, however all RCDs are on the one circuit. No UPS
power or line isolation monitored power is available. This arrangement is not considered
acceptable. Staff advised that on at least one occasion the single circuit to a theatre overloaded
and required an electrician to reset the circuit breaker at the distribution switchboard. As a
minimum it is recommended the following is installed:
• Additional 2 socket outlets per service panel connected to a separate circuit.
• Additional 2 socket outlets on each panel be installed connected to a UPS power supply
and line isolation monitored supply.
• Additional essential circuit and a UPS circuit.
Actual installation design would need to examine the possible equipment arrangements and
ratings.
UPS socket outlets are also recommended and typically installed for other critical care areas
such as HDU, ICU, birthing and emergency resuscitation room and minor operating theatre are .
DE
Surge diverters, filtering or uninterruptible power supplies are generally not provided. The use of
fuse protection in the distribution system is a source of voltage surges if faults short circuits or
overloads occur and therefore it is essential surge protection is installed to protect sensitive
equipment. It is recommended all socket outlets for IT equipment and electronic medical
equipment are protected by surge protection at each floor distribution switchboard.

recommended that a central UPS installation is installed and reticulated to staff stations,
operating theatres, emergency ward, delivery rooms, HDU, NICU and ICU areas where life
maintaining and computer based medical equipment or IT equipment is installed.
In addition to additional UPS power, it is recommended surge protection is provided at all

include an additional transformer.
A water leakage problem occurs in wet weather where water enters the building substation
through underground conduits which penetrate the building at the top level of the basement.
This is a major reliability and safety issue and need correction work. It is recommended that in
addition to sealing all conduit entries to the building and pits leading to the building that an
external conduit drainage pit with sump pump is installed adjacent to the building to collect any
water flowing along electrical conduits.
It was noted that the electricity HV supply conduits entering the building are not fire rated. All
electrical submains supporting emergency services are required to be fire rated by the BCA.
Recommended that fire rating is provided by a fire rated duct or sprinkler protection.
In addition several penetrations through fire rated walls and floors have been carried out
