1. Memorandum Len Taplin Principal Consulting /Chief Engineer Professional Services Portfolio From: Glen Kay Position: Senior Electrical Engineer Division: Electrical Engineering Phone: 3227 8626 Date: 23 July 2007 Subject: Gold Coast Hospital - Electrical Services Audit Len, PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C To: Ref: 50445 DE Inspections of the QEII hospital were carried out on the 8th June, 14th June and the 20th July 2007 with the assistance of Mr David James and Mr Kim Fetter. The purpose of the inspection was to examine the infrastructure which needs to be upgraded to meet current accepted standards and practices. In compiling this report, information has also been used from as installed drawings, where available and information gathered during inspections. Electrical Services Audit - Gold Coast Hospital-CFDE59AB.doc RTI Folio No. 1 -2- 1. 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. 1. 2. 3. 4. PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C The services covered by the electrical services report include the following: Substations and Incoming Supplies Tower Block Block D Mental Health or Psych Building Each building is examined for the following electrical services: • • • • • • • 2. Electrical reticulation Standby Generator System Lighting Emergency lighting General Power Outlets and circuits Uninterruptible Power Supplies. Lifts 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. RTI Folio No. 2 PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C -3- ESK 01 - Substations and Incoming High Voltage Feeders 3. 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 RTI Folio No. 3 -4- • • • • • PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C • 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. DE • RTI Folio No. 4 PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C -5- Typical Distribution Switchboard in part A of the Tower Block – Email E Frame circuit breakers which are in the order of 30 years old. Switchboard chassis is not fully insulated and requires power down of all connected loads to connect a new circuit. 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. PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C It is recommended that future refurbishment of general wards consider the use of more efficient lighting systems with electronic ballasts, T5 fluorescent lamps. DE Typical Ward Bed head Lighting RTI Folio No. 6 -7- PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C Birthing Suite Lighting – Comprising room lights and examination lighting. Pendant and room lighting for Theatres. 3.5 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. RTI Folio No. 7 -8Theatre pendant and examination lighting is supported by 32 and 24 volt DC central battery systems and are locate on level 1 part B on the same level as operating theatres. PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C It is recommended that consideration is given to replacing the existing 240 volt AC central battery emergency lighting with a computer monitored self contained emergency lighting system. This will standardise the emergency lighting systems throughout the complex and simplify maintenance, modification, and extension of the emergency lighting system.

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). DE Typical Ward - Six socket outlet on the LHS of the bed. All are connected to essential lighting circuits. Two are for computer equipment only. One ceiling mounted socket outlet provided for television. Local 6 bed ward RCD Protection for Bed Socket Outlets. One circuit for essential and one for computer socket outlets (also on essential) RTI Folio No. 11 - 12 - Socket outlets in general wards are installed to AS 3003 body protected areas with six outlets adjacent each bedhead. All socket outlets are connected to essential circuits. Two are for computer equipment only. PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C 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. Cardiac Protected Area in Birthing Suite – 6 socket outlets on essential circuit RTI Folio No. 12 PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C - 13 - Operating Theatre main service panel with 4 socket outlets. DE Recovery service panel with 6 essential socket outlets. RTI Folio No. 13 - 14 - 3.7 Uninterruptible Power Supplies The present installation has UPS installed for IT equipment in server rooms and communication cupboards, Cardiac Catheter Ward and each Mechanical Services Switchboard for BMS monitoring. No UPS power is provided for Theatres, Emergency, delivery rooms, HDU, NICU and ICU areas. PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C Recent hospital projects have included reticulated UPS for all these areas to enable electronic computer based equipment to continue to operate in the event of a power outage and to protect such equipment from voltage disturbances due to electrical faults and lightning. It is 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 distribution switchboards serving computer and electronic equipment. 3.8 Lifts. DE Recently completed Cardiac Catheter Ward services panel with blue UPS socket outlets – Level 9 part B/C The Tower block is served by 8 traction lifts which were upgraded in 1997. Lifts 1 and 2 are public lifts and the remainder designed for staff use. Lifts 3 to 8 can operate as emergency lifts and have emergency recall key switch control on the ground floor. Staff lifts (3 to 8) comply with the minimum dimensions for lift car size and entrances for emergency lifts as specified in the Building Code of Australia. Lifts 3 to 8 are sized to accept a stretcher. Lifts 3 and 4 have doors at the front and rear and can be switched between operation for the staff lobby or the public lobby. A fire service key on the ground floor calls all lifts to the ground floor. RTI Folio No. 14 - 15 - PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C All lifts are connected to generator power in the event of loss of normal supply. In the event of only one of the two standby generators failing, only four lifts will operate and comprise two staff lifts and two public lifts. Lifts generally comply with the Australian standard AS 1735.12 - 1994 for Facilities for persons with disabilities however they do not comply with the latest standard dated 1999 in the following points: 1. Control buttons within the lift cars and at landings shall have braille and tactile information. 2. Audible automatic information provided within lift cars. Floors identified in English voice at each lift stop. 3. Braile and tactile information provided for landing control buttons. 4. Automatic identification of each lift at the answering service receiving communication from the lift car. The minimum features required to comply with the current Building Code of Australia is items 1 and 3 – Braille and tactile information.

Psychiatric Unit - Electrical Services 4.1 General The Psychiatric Building was constructed in 1992. The building was designed for the later addition of extra floors. Services have extra space or capacity to allow expansion to extra levels. The first level was refurbished in 1999. Electrical services on ground level are of an older vintage than level 1 and are in need of an electrical upgrade. The lift installation has been recently upgraded and changed from the original Boral to Kone lift installation with new controls. 4.2 Electrical Reticulation PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C The Psychiatric Unit has a separate substation to the Tower Block and Block D. A 1000 kVA transformer powers the building. Due to the electrical infrastructure being sized for additional floors the present main switchboard is lightly loaded and the maximum demand is less than 50% of the supply capacity. The main switchboard is in good condition, however replacement switchgear is no longer available for the Merlin Gerin compact circuit breakers in the event of equipment failures. Lift main switches do not comply with AS3000 as they are down stream of a switch which controls non emergency services. It is recommended the switchboard is relabelled to comply with AS 3000. Main Switchboard Essential Section – MCCB are no longer available Main Switch Labelling is incorrect. 4.3 Standby Generator DE A 165 kVA/ 132 kW Detroit Diesel with Stamford Newage Alternator standby generator is located on basement level and supplies essential lighting, general power, lifts, FIP and ventilation. A single automatic transfer switch connects essential loads to the generator in the event of mains supply failing. The generator is in reasonable condition. RTI Folio No. 17 PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C - 18 - Standby Diesel Engine Generator with base fuel tank. 4.4 Lighting DE Lighting generally comprise recessed plasterboard fluorescent vandal proof luminaires with prismatic diffusers. Lighting in wards is either recessed troffers with prismatic diffusers or bed head lighting. Some luminaires on the ground level are showing signs of ageing and it is recommended all lights are cleaned, relamped and provided with new diffusers. Ground Level lighting is showing signs of ageing. Exit light no longer complies with code. RTI Folio No. 18 - 19 - 4.5 Emergency Lighting 4.6 PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C Emergency lighting on the first floor comprises single point emergency lights with integral batteries and test switches located on distribution switchboards. Emergency lighting on the ground floor appears to be the original emergency lighting installation. Colour of exit signs does not meet the current standard and automatic time delay test switches are provided on the ground floor. Current practise is to provide emergency lighting in all rooms with staff and patients in a secure mental health facility. It is recommended the ground floor lighting is replaced with a compliant system and consideration be given to adding additional emergency lighting in areas where staff are at risk. General Outlets and Circuits Socket outlets in patient areas have vandal resistant stainless steel cover plates. RCD protection of socket outlet circuits is provided on level 1 however RCD protection is limited on the ground level. It is recommended RCD protection is provided to all socket outlet circuits throughout the building. Surge diverters, filtering or uninterruptible power supplies are not provided. It is recommended as a minimum all socket outlets for IT equipment and electronic medical equipment are protected by surge protection at each floor distribution switchboard. 4.7 Lifts Lifts have recently been upgraded from the original Boral lifts to Kone controls. Control panels in cars are provided with facilities for disabled with tactile and Braille information and control buttons. Two lifts are installed with a spare lift shaft for a third lift. The third lift was planned to served future floor levels if installed. DE The two lifts have stretcher facilities with a stretcher recess in the rear of the lift car to provide the 2000 length required by the BCA. Lift car dimensions are as follows: - 1472 Wide, 1709 deep, 2400 High with a 920 wide entrance. Lifts are provided with emergency Call and Fire Service controls, and hands free communications for assistance.

Rehabilitation Building (Block D) Electrical Services 5.1 General Block D is the latest building on site and was constructed in 2001. Electrical equipment is generally in good condition and complies with current practice and standards. The building has basement, and levels ground to 3. Level 3 is not used but is available for future expansion. All lifts can travel to level 3. The building is primarily used for rehabilitation wards and clinics, endoscopy services and consultation rooms. 5.2 Electrical Reticulation PA RT RT I R ME EL E N W T AS OR O E KS F P UB LI C The building has a substation located on the basement level. A 1500 kVA transformer powers block D and out buildings on the west of the complex. The substation is sized for expansion to 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 without maintaining the fire barrier integrity. It is recommended that these are filled with fire rated sealant and certified. 5.3 Standby Generator DE A 350 kVA/ 280 kW Cummins Diesel engine with Stamford Newage Alternator standby generator is located on basement level and supplies essential lighting, general power, fire pumps and fans, lifts, FIP and ventilation. A single automatic transfer switch connects essential loads to the generator in the event of mains supply failing. The standby generator has a heat exchanger located on level 3. Exhaust pipes share the same exhaust riser as the Tower block generators and the same 20,000 litre underground fuel storage system as the Tower Generators. The generator is in reasonable condition.
