University innovation

The latest addition to UNSW’s Physical Sciences precinct at its Kensington campus in Sydney, the new Science and Engineering Building (SEB) features world-class research facilities designed to foster learning and research breakthroughs as well as provide contemporary spaces for students and staff.

The ten-storey building – designed by Grimshaw architects and constructed by main contractor Multiplex – is a companion building to the adjacent Hilmer Building, with the two sharing similar internal layouts, as well as a physical connection and a number of services.

It features seven levels of modular laboratory spaces arranged at the core of the building. These labs are surrounded by light-filled offices,

lecture theatres and classrooms to the perimeter.

Ground and basement levels are dedicated to teaching and study facilities, the Mark Wainwright Analytical Centre (MWAC) and UNSW’s Creative Practical Lab that features the state-of-the-art Io Myers Studio and Studio One performance theatres.

Following a two year period of design development led by engineering firm Arup, A.G. Coombs was engaged by Multiplex as the project’s mechanical services specialist contractor under a Design and Construct contract.

Taking Arup’s preliminary design, A.G. Coombs relied on its engineering, building information modelling (BIM), prefabrication

A new Science and Engineering Building at the University of New South Wales has reinforced A.G. Coombs’ capability to design, construct and deliver complex mechanical services systems that serve a multiplicity of research environments.

and commissioning capabilities to deliver a range of complex mechanical services to support the multiplicity of spaces and functions within the building.

The modular laboratory arrangement and corresponding mechanical services layout was improved through A.G. Coombs’ design that saw the laboratory exhaust system removed from the services-heavy corridor space and instead run through the laboratories alongside the supply duct.

This had the effect of decongesting the corridor and allowing for an easier installation of all services, while minimising penetrations through the smoke-proof walls dividing the laboratories and corridors.

Additionally, A.G. Coombs proposed the adoption of a manifolded fume cupboard exhaust system that required a risk assessment to be completed prior to reaching agreement with UNSW stakeholders.

It was shown that through the use of a manifolded strobic exhaust fan system, a static pressure could be maintained in the duct thereby enabling a single large fan system with N+1 redundancy to serve large numbers of fume cupboards without the need for the same number of exhaust fans. This solution offered considerable energy efficiency benefits.

Where the use of some chemicals made a manifolded system non-permissible, dedicated fume cupboard exhaust fans with onboard scrubbers were used and a constant volume achieved via a bypass sash.

A number of other efficiency improvements were made in the final mechanical services design.

The equipment cooling water (ECW) system, used to support laboratory equipment, was redesigned to a gravity return system while the deletion of acoustic louvres at the cooling tower compound was achieved through the adoption of low noise cooling towers featuring water silencers. Plantroom layouts were also reconfigured to improve installation and maintenance accessibility.

Corridor modules, services risers and laboratory supply air branches were all constructed off-site using prefabrication techniques, as were

the pump skids and large chilled water and condenser water pipe modules that serve the building’s central energy plant.

The use of prefabrication aided in the quality of construction, reduced site activity and associated safety risks and accelerated the mechanical services installation significantly.

A.G. Coombs also led the coordination of services and building information modelling (BIM) – the latter critical in the delivery of the project on time and on budget given the compressed construction programme and complexity of services.

Practical completion of the main works was reached in February 2019. The completion of the basement performance theatres and fitout of Level 5 and 6 laboratories followed in mid-2019.

“We are proud to have delivered the new Science and Engineering Building for UNSW and played a role in creating a world-leading research and education facility,” said Luis Soares, Project Manager for Multiplex.

“A.G. Coombs is recognised for its technical capability, quality and experience in prefabrication and this quality is evident throughout the mechanical services systems that serve the variety of uses across this building.”

Sands of time

There is a long-shared history between A.G. Coombs and the University of Melbourne.

From design and installation of building services systems in both new and refurbished buildings, to the important role of independent commissioning agent (ICA) on others, the A.G. Coombs Group has had a hand in supporting the University’s facilities and status as a world-leader in tertiary and higher education.

Successfully tendering for the mechanical services maintenance contract in 2018, A.G. Coombs Service is working closely with the University of Melbourne to drive transformative change across its campuses as a predictive maintenance model is introduced.

Whilst recognised as one of Australia’s “sandstone universities”, the University of Melbourne’s buildings and facilities are ever-evolving, resulting in a dynamic mix of both historic and new state-of-the-art buildings featuring a wide variety of mechanical services assets of differing age, application and complexity.

Capturing the detail of these assets has been critical to the A.G. Coombs approach, with the first year on site being one of discovery as asset information, including condition, duty and associated expenditure history was captured. Equally important has been the management of the University’s existing fault-logging

procedures and determining the best methods of triage and prioritisation of the number of calls that come from the very large staff and student population.

To this end, a site-specific dashboard system has been implemented to geomap fault calls and the status of service technicians to enhance the management and response to jobs. This has also provided both the University and A.G. Coombs greater visibility of works in progress.

About to enter the second year of the contract, A.G. Coombs is planning to implement with the University a strategic maintenance approach based on the data gathered and learnings to date that is expected to further improve system performance, reduce the number

of plant and equipment failures and the resultant reactive works, and improve equipment lifecycles and cost.

To deliver the maintenance model to date A.G. Coombs has formed a dedicated team of over 20 experienced technicians, management and support personnel to service the University’s campuses. This team works very closely with University management on site, with productive day-to-day dialogue and collaboration between stakeholders is building the foundation for success.

To assist in reducing energy consumption across a number of University buildings, A.G. Coombs has commenced a process that will identify, scope and deliver in conjunction with the University environmental initiatives which will produce lasting savings and other benefits.

“The servicing and operation of our buildings and facilities is critical in maintaining the University of Melbourne’s position as a worldleading university,” said Colin Reiter, Director Campus Services at the University of Melbourne.

“Having a single provider like A.G. Coombs engaged with the University, who is committed to being responsive and collaborative with our team, will contribute to improvements in the operation of our buildings for the benefit of our students and staff.”

Hands on learning

A.G. Coombs has played an important role in the creation of a new world-class facility at Holmesglen Chadstone that brings Vocational Education and Training (VET) together with industry to secure the future of mechanical services training in Australia.

Purpose-built, the HVAC Centre of Excellence is the first of its kind to offer applied learning and has been designed to offer mechanical services professionals with a clearer pathway from training to their career.

The Centre is the result of a collaborative partnership between Holmesglen and the nation’s peak mechanical contracting body, Air Conditioning and Mechanical Contractors’ Association (AMCA). It has also received government support through the Workforce Innovation Training Fund.

The training facility features cutting-edge equipment and technology in a simulated environment that replicates the technologicallyadvanced and environmentally efficient mechanical services systems found in today’s climate-controlled buildings.

As well as having been designed to upskill existing HVAC tradespeople and train tomorrow’s mechanical services professionals, the Centre also provides an opportunity for teachers to advance their skills and knowledge.

It is hoped it will also attract new teachers to meet the increasing demand for mechanical services training.

The A.G. Coombs Group is proud to have been intimately involved in the development of the Centre, including providing direction and input to the design of the training facility.

A.G. Coombs Projects also carried out the installation and commissioning of the equipment and systems used for training. This includes air handling units, variable air volume boxes, ductwork systems, chillers, boilers, pumps, valve arrangements, an energy recovery ventilation unit, heat exchangers, chilled beams, hydronic and underfloor heating systems and various split air conditioning systems.

As well as the latest HVAC equipment, the Centre also provides industry with a glimpse into the future of digital deliverables through a Building Information Modelling (BIM) laboratory, commissioning laboratory and an augmented reality environment.

The 3D interactive model of the Centre’s laboratory not only illustrates the size and scope of the facility, but also allows the viewer to investigate various items of plant and equipment. Each “tag” provides detailed information about the asset as well as operational and maintenance information.

The new HVAC Centre of Excellence at Holmesglen’s Chadstone campus opened in late May 2019.

“The industry is rapidly evolving, with new technologies continuing to emerge,” said Holmesglen’s Dean of Building, Construction and Engineering, Ross Digby. “This Centre will allow us to stay at the forefront and give our future learners plenty of new training opportunities.”

In his role as AMCA National President, A.G. Coombs Group Managing Director Russell Telford said that rapid advances in the HVAC industry are bringing changes to the skills required by both qualified technicians and new entrants to the industry.

“The AMCA has committed to developing and growing partnership arrangements with TAFEs to address these challenges,” he said.

He has identified three key themes for industry and VET collaboration.

“The first is to establish a culture of co-investment between VET, industry and government. The second is renewing the focus of quality industry-led outcomes. And finally, elevating the status of apprenticeships by communicating how it will lead to a sustainable career pathway.”

“This Centre will allow us to stay at the forefront and give our future learners plenty of new training opportunities.”

Regional good health

A state-of-the-art redevelopment of Goulburn Valley Health in Shepparton will deliver new and expanded healthcare facilities to meet the growing community needs of one of Victoria’s most important agricultural regions.

The $172 million expansion of GV Health’s Graham Street, Shepparton campus will see the addition of a new fivestorey inpatient unit (IPU) building accommodating 64 inpatient beds, 10 intensive care unit beds, four operating theatres and a new kitchen. A new emergency department will increase its previous capacity.

The redevelopment will also include a women’s and children’s precinct, a new dialysis unit and the upgrade of existing facilities and services infrastructure.

With a proven track record of delivering major health projects, including the new Bendigo Hospital, the multi-stage redevelopment of GV Health Shepparton was awarded to managing contractor Lendlease in 2017.

The first two stages of the project are scheduled for completion in early 2020.

Walker Fire Protection was engaged by Lendlease in late 2018 to install and commission fire protection systems as part of an integrated fitout of the new IPU building. These works have included the installation of fire protection systems serving a variety of spaces in the building, including the car park, café, operating theatres, emergency department, dialysis unit, patient wards and plant room – each with their own standards and code requirements to be met.

To avoid interruptions to critical hospital services and day-to-day operations during the construction and refurbishment works, detailed planning and coordination between GV Health and the project’s construction teams has been required.

The installation of all new fire protection systems and their connection to the health service’s existing operating systems will be completed by Walker Fire Protection with minimal disruption to the health service or patients. Careful management of materials, delivery and handling on the spatially-constrained site has also been required to avoid inconvenience to hospital staff, patients and visitors.

The refurbishment and upgrade of existing facilities, services and systems at the health service is proposed and would form a second stage of the project.

To this end, Walker Fire Protection completed a detailed survey of the existing fire alarm system to ascertain the available system capacity and its compatibility to the new systems being installed as part of the redevelopment. An upgrade of the proposed fire system network schematic was adopted that will allow for the construction and testing of the new services to be conducted with minimal impact.

As part of the project’s local jobs policy, and the Victorian Government’s Major Projects Skills Guarantee, Walker Fire Protection has employed apprentices and local labour on the project alongside its Melbourne-based project team.

The installation of all new fire protection systems and their connection to the health service’s existing operating systems will be completed by Walker Fire Protection with minimal disruption to the health service or patients.

A canvas of silence

Melbourne Conservatorium of Music features one of the largest oculus windows in the world.

Best known for his work with the Philadelphia Orchestra, British conductor Leopold Stokowski is said to have addressed an audience at New York City’s Carnegie Hall with what would be his most famous quote:

“A painter paints pictures on canvas,” Stokowski said. “But musicians paint their pictures on silence. We provide the music, and you provide the silence.”

While his words quietened the audience in attendance, they also hold true of any music venue and the people behind its design – each playing a vital role in the acoustic environment, or as Stokowski might put it, the canvas of silence.

Facilities like the Melbourne Recital Centre are world-renowned for their acoustic performance thanks, in large part, to the careful design, construction and commissioning of building services and noise controls.

It is through its involvement with the Melbourne Recital Centre that the expertise of A.G. Coombs continues to be called upon a decade later.

Engaged as Independent Commissioning Agents (ICA), A.G. Coombs Advisory has contributed to the construction of two new music Conservatorium projects in Melbourne and Hobart.

Central to the University of Melbourne’s $200 million Southbank campus redevelopment, the state-of-the-art Ian Potter Southbank Centre is the new home to the Melbourne Conservatorium of Music (MCM) – Australia’s oldest and most prestigious music institution.

Designed by award-winning John Wardle Architects and constructed by Lendlease, the building features a 400-seat cantilevered auditorium, 200-seat studio and numerous world-class performance, teaching, recording and rehearsal spaces. It is also home to one of the largest oculus windows in the world.

Continuing its long association with the University of Melbourne, A.G. Coombs Advisory was engaged as the ICA on the project in October 2017.

Providing building services commissioning advice to the project team, A.G. Coombs Advisory worked closely alongside building services engineers Aurecon and acoustics consultant Marshall Day.

With every building element of the Conservatorium affecting the acoustic performance and resonance of these spaces, the tuning and commissioning of the low air velocity mechanical services design was critical. Air distribution, mechanical isolation and fire mode were all considered during this process.

“The Melbourne Conservatorium of Music is an important addition to the University of Melbourne’s Southbank campus,” said James Dalglish, Project Engineer (ICA) at A.G. Coombs Advisory.

“A.G. Coombs’ expertise in building services commissioning, and experience in similar projects, has contributed to the completion of a facility that all project members can be extremely proud of.”

Across Bass Strait, a similarly impressive landmark building is nearing completion in the form of The Hedberg.

Considered one of Tasmania’s most ambitious arts projects, the $96 million creative industries and performing arts development in Hobart incorporates the University of Tasmania’s Conservatorium of Music and the refurbished Theatre Royal – one of Australia’s oldest operating theatres.

Delivered by Hansen Yuncken, The Hedberg building features a contemporary recital hall, studio theatre and salon, as well as a range of teaching and music rooms.

Appointed ICA on the project in 2016, A.G. Coombs Advisory has provided specialist building services commissioning advice including detailed design, constructability and commissionability reviews as well as construction inspections and commissioning witnessing.

“In an environment where acoustic performance is paramount, there are a host of challenges associated with the building services that support the facility,” said Warwick Stannus, A.G. Coombs’ Independent Commissioning Agent for The Hedberg project.

“A.G. Coombs Advisory has applied its experience and technical expertise to ensure these challenges have been overcome, and the acoustic requirements of the project have been met.”

While each project has presented its own unique set of challenges, the design of life safety systems, particularly given the complex arrangement of spaces and large number of patrons within the building at peak times, has been common to both.

A.G. Coombs Advisory’s contribution to the delivery of these special buildings will ensure Australia’s rich history of academic and musical excellence is nurtured for years to come.

Building on its reputation in the recital hall space, A.G. Coombs has played a key role in the commissioning of two new conservatoriums that will contribute to enriching the study of music and the arts in Australia.

With every building element of the Conservatorium affecting the acoustic performance and resonance of these spaces, the tuning and commissioning of the low air velocity mechanical services design was critical.

Survival at sea

The Royal Australian Navy’s principle training establishment for naval personnel in Victoria, HMAS Cerberus has played a crucial role in preparing Australia’s defence forces for the rigours of sea since 1920.

Located 75 kilometres south-east from Melbourne near Crib Point, on Western Port Bay, HMAS Cerberus occupies over 1,500 hectares and includes training and recreational facilities, office and living-in accommodation, two chapels and a marina.

As well as being home to approximately 980 staff, the base is capable of accommodating 1,100 trainees at any one time –providing 6,000 training places annually across 300 courses ranging in duration from one week to one year.

Following an engineering assessment on the condition, capacity and compliance of the facilities and infrastructure at HMAS Cerberus in 2013, the Department of Defence committed $463.1 million to the redevelopment and upgrade of the base’s training, support and accommodation facilities.

The project is being delivered by managing contractor Lendlease in two phases.

Phase One will see important infrastructure and services upgrades completed to HMAS Cerberus buildings and facilities.

Walker Fire Protection has been engaged by Lendlease to upgrade the fire and smoke systems within the base’s existing buildings, including training facilities, administration spaces, Living in Accommodation (LIA) and the base’s galley.

A separate works package, includes the construction of a new training ground and support facility for the new Royal Australian Navy School of Survivability and Ship Safety.

A.G. Coombs Projects has been engaged by Lendlease as head contractor on this unique aspect of the overall project.

These new facilities include a simulator control building, a Dynamic Leak-Stop-Repair simulator, a gas-fired diesel firefighting simulator and a portable extinguisher practical training fire pit.

Modelled on an existing facility operating at HMAS Creswell in New South Wales, the Dynamic Leak-Stop-Repair Training Unit (DLSRTU) is a multi-deck ship simulator that replicates the conditions of a navy ship at sea. It is capable of being flooded and oscillated to 10 degrees via a specially-designed hydraulic system to allow for realistic combat survivability training.

Another training facility replicates the environment of a fire onboard a navy vessel, such as that encountered in an engine or electrical room.

A.G. Coombs is designing and installing the mechanical building services required to create the training environments of each simulator, with Walker Fire Protection engaged to design and install a water mist system. Normally installed to quell a fire, the system installed within the firefighting simulator will instead be used as a training aid to create confusion among naval personnel undergoing training.

Project wide, all services are being designed and installed to strict Defence security requirements.

Both A.G. Coombs Projects and Walker Fire Protection have leveraged from the A.G. Coombs Group’s capability, and previous experience in Defence projects, in the successful delivery of the HMAS Cerberus redevelopment project.

““The HMAS Cerberus redevelopment will not only deliver key infrastructure improvements but will also enhance the Royal Australian Navy’s training capabilities,” said Barry Hope, Construction Manager for Lendlease.

“A.G. Coombs and Walker Fire Protection have brought technical expertise across multiple disciplines to the project, as well as an ability to meet compliance with well-documented processes and procedures, which is critical to a project like this.”

Phase One of the HMAS Cerberus redevelopment is scheduled for completion in mid-2020.

“The HMAS Cerberus redevelopment will not only deliver key infrastructure improvements but will also enhance the Royal Australian Navy’s training capabilities.”

For the care of our kids

Located in South Brisbane, the Queensland Children’s Hospital (formerly known as Lady Cilento Children’s Hospital) is the major children’s hospital for families living in Queensland and northern New South Wales.

Designed around the needs of patients and their families, the hospital opened to the public in 2014.

As one of the largest and most advanced paediatric hospitals in Australia, it features a floor area in excess of 100,000m² across 16 levels.

As well as providing specialist healthcare to the most ill and injured children in the state, the hospital plays an important role in paediatric training and medical research. The Centre of Children’s Health

Research, Queensland’s first fully integrated research facility focused on child and adolescent health research, is co-located at the hospital.

Consequently, the Queensland Children’s Hospital features a number of specialist mechanical services systems to support the delivery of quality healthcare, training and research. This includes a central energy plant that satisfies the site’s entire power, heating, cooling and steam requirements via a large trigeneration system featuring two gas-powered 2,400kWe generators.

Despite not being involved in the design or construction of the Queensland Children’s Hospital, A.G. Coombs Advisory has, from time to time, been engaged by the hospital’s in-house engineering team to provide technical support and advice on a range of matters.

Behind the colourful walls of the Queensland Children’s Hospital are a range of mechanical services systems that maintain a world-class environment in which sick and injured children receive highly specialised care.

Through this collaboration, the A.G. Coombs Group of companies has been able to demonstrate its capabilities and technical expertise in a number of areas. This eventually led to A.G. Coombs pursuing the hospital’s mechanical services maintenance contract with a proposal that challenged the business-as-usual delivery model of HVAC maintenance.

In the last quarter of 2018, A.G. Coombs was formally engaged to deliver the contract from the 1st January 2019 under the hospital’s Facility Manager, Medirest – part of Compass Group Australia.

Required to mobilise in a period of less than two months, A.G. Coombs deployed a small but experienced team of skilled technicians permanently at the hospital. It then set about completing an asset verification program that also allowed the team to become familiar with all existing assets and building layouts.

Additionally, A.G. Coombs has implemented an alternative methodology and frequency of mechanical services plant maintenance that aims to reduce the number of service and fault calls, and identify opportunities where operational expenditure can be reduced.

Given the critical nature of the hospital’s operations, the maintenance contract sets out a number of strict Key Performance Indicators (KPIs) that need to be met.

This includes a requirement that 12-hourly checks of the steam boiler plant be conducted. To meet this demand, A.G. Coombs has introduced morning/afternoon shifts for its on-site technician team and a permanent 12 hour/3 day shift incorporating Friday, Saturday & Sunday. While unusual in the HVAC industry, this shiftwork approach has created opportunities for after-hours maintenance to be carried out in areas that are otherwise difficult to access during normal (peak) hospital hours.

Clinical spaces such as clean rooms, infection control rooms, operating theatres, intensive care unit and specialist wards for the treatment of burns and bone marrow transplants also require a planned approach to maintenance in order to adhere to hospital processes. A complex fire matrix must also be negotiated carefully.

Building on the company’s experience at other critical healthcare facilities around Australia – including the Royal Children’s Hospitals in Melbourne – the A.G. Coombs team is working with Medirest to add value to the mechanical services maintenance contract.

Through the improved performance and maintenance of the mechanical services systems serving the Queensland Children’s Hospital, A.G. Coombs is playing an important role in delivering a world-class hospital environment for the benefit of patients.

“The Queensland Children’s Hospital is one of the state’s most important healthcare assets,” said Michael Caldwell, Hard FM Operations Manager for Medirest.

“In the few months since A.G. Coombs has joined our team, the quality and expertise of their technicians has been evident – as has their ability to perform their work in a manner that puts hospital patients, families and staff first.”

New chapter in Australian success story

CSL Behring is a global biotherapeutics leader driven by its promise to save lives. The parent company, CSL Limited, headquartered in Melbourne, Australia, employs more than 22,000 people, and delivers its life-saving therapies to people in more than 60 countries.

The CSL Behring Broadmeadows site in Victoria is Australia’s national plasma fractionator and is the only commercial-scale facility of its type in the southern hemisphere.

Now the addition of a new manufacturing facility at the site will help CSL Behring meet the growing global demand for Albumin –a protein derived from human plasma that is used in critical care to treat burns and shock.

Construction of the three-level, 23,900m building was managed by builder, Cockram Construction (now Icon).

In 2015, A.G. Coombs was appointed as the project’s mechanical services specialist contractor and tasked with bringing to life a highly complex mechanical services design documented by consulting engineer, Irwinconsult.

This included the integration of specialist process systems for manufacturing requiring chilled water, heating hot water, steam and compressed air, as well as a services-heavy HVAC solution.

The design also called for the control and management of strict air pressure regimes including transitions between high pressure in good manufacturing process (GMP) areas and low pressure spaces such as corridors and offices.

In an Australian first, a specially-designed laminar air flow booth was also installed within the facility. Supplied from Europe and

constructed on site by A.G. Coombs, the stainless steel facility features HEPA filtration and dedicated air handling plant to manage the high number of air changes required per hour.

The A.G. Coombs project team worked with CSL engineers from the construction phase through to the commissioning process.

A.G. Coombs led the coordination of all services on site, as well as the delivery of the project in BIM (building information modelling) to satisfy the high level of attention to detail required. Additionally, a process for documentation management was implemented, with one A.G. Coombs project team member dedicated to seeing the commissioning period through to completion.

An A.G. Coombs commissioning technician also remained on the site during the Defects Liability Period (DLP).

Following the completion of the project, A.G. Coombs hosted a client de-brief conducted by an independent facilitator. Thirty-five people from the project, including key stakeholders CSL and Cockram

Construction attended, where outcomes were discussed and key learnings documented.

The lessons from the CSL AlbuRx project are now being applied in the delivery of a new manufacturing facility at Broadmeadows, where A.G. Coombs has also been engaged as mechanical services contractor.

“On a project as technically complex as CSL’s AlbuRx facility, it is important that all project team members are focused on delivering a high quality outcome,” said Louise McKinnon, Project Manager for Cockram Construction.

“A.G. Coombs’ technical abilities and attention to detail, as well as its dedication to seeing the commissioning of the facility through to the end has proved invaluable.”

The new facility required the integration of specialist process systems for manufacturing requiring chilled water, heating hot water, steam and compressed air.

Closer to the action

Akey role was played by A.G. Coombs in the construction of the new $360 million Western Sydney Stadium, now known as Bankwest Stadium.

Part of the NSW Government’s Stadia Strategy that seeks to improve sporting infrastructure across the State, the new stadium replaces the former Parramatta Stadium while increasing spectator capacity by 10,000.

Designed and built by a consortium led by Lendlease and designed by Populous Architects, Bankwest Stadium offers modern corporate hospitality facilities, including Australia’s first continuous suite deck and a new conferencing and banqueting centre. It also features the steepest grandstands in the country, designed to bring fans closer to the action and amplify the noise of the crowd. The acoustics are further enhanced by the specially-designed roof.

A.G. Coombs’ early engagement as design and construct mechanical services contractor in mid-2016 afforded the project team the opportunity to explore a range of solutions, as well as influence final architectural and structural design decisions.

By exploring alternate mechanical services design paths, the aesthetic appeal of the stadium design was maintained while opportunities to reduce cost were identified.

For example, the A.G. Coombs Group’s experience in data centre CFD modelling was applied to validate alternate design concepts. The discharge of kitchen exhaust under the fabric roof and the thermal load on the stadium’s electric substation were two problems for which CFD modelling was used to develop solutions.

The resulting substation design removed the need for the rigorous mechanical ventilation requirements set out by the energy provider and will influence similar designs in the future.

The project’s ambitions of achieving a Leadership in Energy and Environmental Design (LEED) Gold certification underpinned many of the mechanical services design decisions, and led A.G. Coombs to perform life cycle cost scenarios on the possible system solutions.

Life cycle analysis showed that because of the sporadic use of the air conditioned corporate facilities within the stadium two 1150kW aircooled chillers in a primary only pumping arrangement in conjunction with two 505kW gas-fired condensing hot water generators was the most cost effective arrangement. This system provides chilled water and heating hot water to the air handling units (AHUs) and fan coil units (FCUs) serving the five floors of the western stand.

A new 30,000-seat sports stadium in Parramatta is bringing rugby league, union and soccer fans in Sydney’s west even closer to the action.

A.G. Coombs’ early engagement as a full D&C mechanical services contractor afforded the project team the opportunity to explore a range of solutions, as well as influence final architectural and structural design decisions.

Selected with 65 per cent spare capacity on the calculated design day load, the air-cooled chillers were deemed to provide optimum performance over the 50-year life cycle of the stadium. High efficiency, variable speed pumps with N+1 redundancy were also selected for both cooling and heating pumping systems.

The HVAC design serving the air-conditioned spaces of the western stand largely consist of variable flow AHUs serving variable air volume (VAV) terminal units to provide local temperature control and thermal zoning. The use of larger AHUs afforded the benefits of economy cycles and CO2 control, reducing energy consumption and helping to assure indoor air quality. Function suites are served by a VAV system that can be disabled when the spaces are not occupied.

On non-event days when the total demand on the chilled water system is low, the large thermal inertia of the system is utilised to condition spaces such as offices or preparation kitchens with minimal chiller plant activation required. This design has avoided any requirement for a low-load chiller.

Distributed FCUs serve a variety of other spaces in the western stand that experience different usage profiles, including satellite kitchens, stadium office spaces and the atrium. A number of smaller, self-contained spaces located throughout the eastern, northern and southern stands are served by a mix of package units, split systems and ventilation fans.

As the lead contractor for services coordination, clash reporting and building information model management, A.G. Coombs worked to an accelerated construction program that saw the project completed on time and under budget by late 2018.

Four months later, the stadium held its first sporting event with a clash between NRL teams Parramatta Eels and West Tigers.

“The new Bankwest Stadium has been designed and built for the people of Western Sydney and forms a key part of the transformation and revitalisation of Parramatta,” said Richard Yarad, Construction Manager for Lendlease.

Arrivals and departures

A record 37.4 million people travelled through Melbourne Airport in the 2018/19 financial year, making it the busiest year in the airport’s 49-year history.

Managing passenger movement through the facility securely, and in safety and comfort, is critical to Melbourne Airport’s growth and standing as one of the world’s leading international and domestic airports.

More recently, management of the airport’s Terminals 1, 2 and 3 has been enhanced through the upgrade of its sophisticated building management control system (BMCS).

The upgrade is the result of three years of work undertaken by A.G. Coombs Advisory, on behalf of the airport’s owner, Australian Pacific Airports (Melbourne).

Engaged in 2016, A.G. Coombs Advisory undertook a thorough review of Melbourne Airport’s existing BMCS to determine the most

appropriate path forward for a system upgrade. This took into account the current and future demands placed on the system by a number of critical airport functions including IT systems, energy efficiency, operational visibility, and also the potential for integration with third party systems such as lighting control, aircraft information systems, aerobridges and transportation systems.

Several options were identified; total BMCS replacement, upgrade of the aging, redundant system and then migrate the entire site to that platform, or upgrade and conversion of the redundant equipment to the more recent BMCS installation that already managed approximately one-third of the facility including the new Terminal 4.

The cost, value and logistics of each option – including risk factors such as site disruption and business continuity – was evaluated against maintaining the most modern system and migrating the remainder of the airport’s buildings onto the same BMCS platform.

It led the A.G. Coombs Advisory team to recommend the third option, which was subsequently accepted by the airport owner.

Development of a new Melbourne Airport BMCS Standard was the key deliverable of the Concept Design Phase. Completion of a schematic design report followed, including documentation of the processes required to complete the upgrade. Additionally, thorough benchtesting of all steps in the controls upgrade process was completed in conjunction with the controls provider, Schneider Electric.

In consultation with airport management and project manager, Root Partnerships, implementation of the BMCS upgrade commenced in late 2017. It has been carried out around embargo periods such as major public holidays, with little impact to airport operations.

As well as the BMCS platform upgrade which included new graphic display pages, configuration of trend data, reporting and alarm functionality, the project has involved the replacement of

approximately 50 network controllers, while the databases of over 3,500 field controllers located across the airport have been converted and reinstated into the new BMCS.

Additionally, the upgrade is being implemented with an eye to assisting the airport meet its energy efficiency targets. Consequently, a number of the airport’s sub-systems are being integrated into the new BMCS including flight information displays, baggage handling, aerobridge, lighting control, metering and transportation systems to provide greater visibility and control of their operation.

The control strategies of the airport’s two large central energy plants have also been upgraded, with each plant re-commissioned and being tuned over the next 12-months for energy efficient operation.

The updated Melbourne Airport BMCS Standard reflects the upgraded system and now forms part of the airport’s Standards documentation. A style guide for the look and feel of the new BMCS interface has also been developed.

A Building Efficiency Optimisation Program (BEOP) devised by A.G. Coombs Advisory is now underway to help the airport achieve its sustainability targets. This will include a deep-dive review of Melbourne Airport’s control strategies.

“The year-to-year growth of passenger numbers through Melbourne Airport demands that we get the best and most out of our building management control systems,” said Jeff Mansfield, Senior Development Manager – Utilities and Services at Melbourne Airport.

“A.G. Coombs’ process-driven and outcome focused approach, supported by its technical and practical experience, has ensured the BMCS upgrade will meet the needs of the airport both now and into the future.”

“A.G. Coombs’ practical expertise, commitment and ability to add significant value to the project has ensured the BMS upgrade will meet the needs of the airport both now and into the future.”

A number of the airport’s sub-systems have been integrated into the new BMS including flight information, baggage handling, aerobridge, lighting control, metering and transportation systems to provide greater visibility and control of their operation.

A substantial upgrade to its sophisticated building management and control system has enhanced Melbourne Airport operations and energy efficiency.

AIRAH and Fire Protection Association Awards for A.G. Coombs Group

Eliminating Overhead Drilling with Technology

Exposure to silica dust and other risks from overhead drilling into the underside of concrete slabs to install building services fixings is a significant Work Health and Safety concern in the building construction industry.

A.G. Coombs pioneering use of digitally located Cast-In Anchors for pre-poured concrete decks significantly reduces the extent of overhead and at height work carried out during typical services installation. This eliminates potential exposure to silica dust, manual handling, working at height and debris in eye injuries

Leading performance in project innovation and sustainability has seen A.G. Coombs Projects and consultants AECOM recognised with the Australian Institute of Refrigeration, Air conditioning and Heating (AIRAH) Award for Excellence in Innovation, and the AIRAH Award for Excellence in Sustainability, both for the International Convention Centre Sydney.

Virtual Buildings Information System –A Key BIM to FM Industry Initiative

There remains a significant gap between the digital models and data sets being used for construction, and the hand-over of useful information to facility managers. There is also a functional disconnect between the modelling and the data set content that is useful to facility managers such as operating and maintenance procedures, technical data sheets, schedules of equipment, commissioning and warranty information.

As a consequence, digital models and their associated data sets are significantly under-utilised post construction and their potential to support improved ongoing facility management, operation and maintenance is largely unrealised.

The Virtual Buildings Information System facilitates transfer of valuable

information from digital construction processes to building owners and facility managers.

Developed by A.G. Coombs Advisory with industry partners and significant assistance from the Victorian Government’s Future Industries Sector Growth Program the system is aligned to the Victorian Digital Asset Strategy VDAS, and based on an open syntax standard that will be freely available to the market. This straightforward system makes possible the calling up of useful information from a range of applications including Building Information Models and FM systems to link to associated data sets seamlessly, regardless of what stage in the building life-cycle. vbis.com.au
