Fiji’s new-look airport As the international gateway to the Fiji islands, Nadi International Airport has been redeveloped through a major modernisation project that improves the traveler experience and enhances Fiji’s reputation as a major tourism destination.
Installed by Fiji’s largest mechanical services contractor, Mechanical Services Limited, the new HVAC system operates from 12 plant rooms and Fiji’s largest water-cooled chiller.
Located on the west side of Fiji’s main island, Viti Levu, Nadi International Airport handles 97 per cent of Fiji’s annual international passenger arrivals and is the most strategic asset owned and operated by Airports Fiji Ltd, a fully Government owned Commercial Company. Historically Nadi Airport was made up of three buildings constructed at different times over the last 70 years.
Operating since 1971, Mechanical Services Limited employs 250+ staff, including skilled technicians and HVAC engineers, from its head office in Suva and branches in Nadi and Labasa. The company provides mechanical services including refrigeration, air conditioning and ventilation, sheet metal works, stainless steel works, plumbing, automation and controls across Fiji and the Pacific islands.
The Nadi Airport Terminal Modernization Project (NATMP), worth $132 million, was undertaken to transform the Airport into a modern, upgraded, bigger and better terminal. Built by New Zealand firm Hawkins in partnership with Fiji’s largest building company Pacific Building Solutions, the NATMP involved upgrading every square inch of the Nadi International Airport terminal building. This included the extension and redesign of the arrivals and departures halls, and a redeveloped immigration arrivals area that provides natural light and views.
Fantech is pleased to have supplied a number of fans to Mechanical Services Limited for the NATMP. Paul Smith, Internal Sales Engineer at Fantech, said the majority of Fantech products supplied for this project were 710mm and 1000mm diameter New Generation Series roof mounted smoke spill fans. These are an integral part of the fire and life safety operation of the building. Other general fan products supplied included PowerLine Series, Ring Plate Series, Adjustable Pitch Axial Series and the Heritage Series.
When you enter the Airport today you will be welcomed by a world class facility. The upgrades were undertaken to enhance the passenger experience by providing seamless processing in arrivals and departures. The airport now features additional facilities such as a non-denominational prayer room, enhanced retail, food and beverage offering and a children’s play area to complement the modern traveller’s needs.
Fantech also supplied a number of Danfoss Vacon Variable Speed Drives and attenuators on the project.
The Nadi International Airport features an environmentally sustainable design (ESD) and is the first airport in the South Pacific to receive Level 1 Airport Carbon Accreditation by the Airports Council International. Many of the airport’s existing building services and HVAC systems have been replaced with a design by local building services engineering company Irwin Alsop Pacific.
“Fantech has worked closely with our Projects Team on fan and attenuators selections, to ensure the equipment met the needs of the project. Fantech’s sales support has been very valuable, and we are delighted with the outcome.”
“The redevelopment of the Nadi International Airport has been an important project for the country, and we have been proud to be part of it,” said Mr Shiv Nand Sharma, Managing Director of Mechanical Services Limited.
The upgrades at Nadi International Airport came to a practical completion in April this year. The second phase has now started which is the theming of the terminal building.

Technically Speaking with Lucas Campbell
Ventilation in small indoor swimming pools Ventilation is essential for enclosed swimming pools and spa rooms for the following reasons: • To prevent the enclosure becoming excessively humid; • To eliminate or minimise condensation; • To prevent the build-up of chloric acids, which are highly corrosive and potentially harmful; • To ensure chlorine fumes and/or odours do not migrate to adjacent indoor areas; • To maintain comfortable conditions for bathers. BCA
BCA requirements for small indoor swimming pools Where swimming pools are enclosed, the Building Code of Australia (BCA) requires natural ventilation complying with clause 4.6, or mechanical ventilation complying with AS1668.2 or AS/NZS 3666.1. Australian Standard AS1668.2-2012 specifies a minimum flow rate per m² of floor area in APPENDIX B. These flow rates are listed below for their respective pool types: • Spas and Hydrotherapy pools - 15l/s.m² • General Pool and Deck areas - 10l/s.m² It is important to note that these values are specified as a minimum only. In internal spaces where temperatures exceed 30°C or there is agitated water surfaces, it may require significantly higher hourly air change rates. For the purpose of minimising contaminant levels, AS1668.2-2012 also recommends that the intake side of the fan is positioned as close to the pool surface as practical.
Corrosion resistance to chlorine The formation of chlorine-saturated condensation in pool enclosures creates an aggressive electrolyte that causes corrosion. Steel fan components suffer heavily from these types of conditions as do aluminium components such as impeller blades and inlet cones. Epoxy-coated fans offer a degree of corrosion resistance against chlorine water however they are not suitable for the extraction of dry chlorine fumes. It is also important to note that chemical compatibility databases such as Cole-Parmer only list epoxy as satisfactory up to 22°C. For this reason Fantech recommend fans with a chlorinated rubber coating, a protective layer highly effective in resisting hypochlorous acid.

Appropriate ventilation solutions The correct ventilation solution for a given pool enclosure depends on a number of variables – including the pool surface area, the enclosure volume and whether or not the area is sealed from adjacent rooms. The required 10-15 l/s.m² of replacement air may be drawn from an adjoining room, however taking conditioned air from this room will significantly decrease the building’s energy efficiency during both winter and summer months. It is therefore recommended that the following two methods are considered: • Saturated air is exhausted via a roof/wall mounted fan(s) at, or above the specified minimum flow rate. A supply air fan positioned at the opposite end of the enclosure should replace the exhausted air at a flow rate no more than that of the exhaust air unit. This ensures that a slight negative pressure is maintained within the swimming pool enclosure. • Alternatively, to minimise running costs, a supply air fan may be replaced with louvered fresh air openings allowing low velocity air to enter the pool enclosure. The fresh air openings should be positioned opposite the exhaust air unit(s) to prevent short circuiting and areas with stagnant air. Air may be exhausted from a pool enclosure via roof, wall or window mounted fans. Duct mounted fans are also suitable, providing the fan and surrounding duct work are treated to avoid accelerated corrosion. Roof mounted fans should have a vertical discharge to ensure all contaminants are ejected away from the building envelope. This also reduces the risk of roof cladding, fittings and other components adjacent to the discharge suffering from exposure to chlorine. For the same reason, wall and window mounted fans should not discharge directly onto surrounding structures.
Clowning around for a great cause
Fans by Fantech Product Selection Program with Stuart Bryson
Hints and Tips
Fantech Queensland conducted the third annual Ride for Clown Doctors event early last month with a record number of participants cycling across three separate routes. One dollar for every kilometre ridden by participants raised around $5,000 for The Humour Foundation.
Exporting drawings for a Schedule
When you have a Schedule of fans selected in the program, you can export all the drawings at once, rather than each fan individually.
The Humour Foundation spreads “doses” of good fun and laughter to people in need across Australia. It operates four programs including Clown Doctors who work with medical professionals to engage with children in hospitals - proving that laughter really is the best medicine.
In the Edit Schedule screen, click Export, then select Specifications. For each fan or silencer, you have the option to export the specification of each item in an Excel, CSV, XML or PDF format, or none. You can then select the drawing format (for fans only) to be in DWG, DXF or Revit (RFA).
According to organiser, Fantech Queensland’s Lynda Griffiths, the event was inspired by Mechanical Contractor’s AE Smith’s fundraising efforts for Clown Doctors in the past, of which Fantech was a supporter. “We became so connected to the important work of the Clown Doctors that we decided to continue our support by starting our own small cycling fundraising event,” Lynda said. “That was three years ago and the event continues to grow.”
Click the Export button, and choose a Folder to export the files to. The program will put each specification (if selected) and each drawing into that folder, which can then be used in the drafting process.
This year over 60 riders participated, including Fantech Group CEO Mark Rickard, Non-Executive Director of Elta Group John Bent, Fantech Queensland’s State Manager Shawn …participants Harris, Fantech Trade’s National Sales Manager raised around $5,000 Darren Robinson and Applied Technology’s National Manager Rudi Van Rensburg. for The Humour Foundation.

The event included a “fast-paced” ride covering 80km with some significant climbs, as well as a more “relaxed” ride chaperoned by the Gold Coast’s all-female cycle group, the Spin Sisters. Fantech would like to thank all those who supported this year’s Ride for Clown Doctors, including TEW Solutions who graciously supplied the support truck, and Just Ride Nerang for the much needed coffee and breakfast after the rides.

Seismic tested fans now available

To successfully supply fans to the VAE Group for the Christchurch Hospital, Fantech has completed a series of seismic testing on a group of its fans.
acceleration outlined within NZS4219. Additionally, the fans were tested to the acceleration limits specified within the design requirements of the Christchurch Hospital project.
The ability of engineering systems in buildings to be securely restrained for an earthquake, and preventing them from collapsing or damaging property, has become increasingly important in light of the series of devastating earthquakes that affected Christchurch in recent years.
All fans tested passed AC156 shake-table testing at both acceleration limits and continued to operate afterwards.
Similarly, it is important that essential engineering systems (such as ventilation for operating theatres and areas handling medical emergencies) continue to function in critical buildings such as hospitals both during and after an earthquake. Working with a leading Australian University, Fantech tested a number of in-line Axial, PowerLine and FlexLine fans to ensure they meet the requirements of New Zealand Standard 4219:2009. NZS4219 sets out the seismic performance requirements of engineering systems related to a building’s function. While NZS4219 provides requirements for restraining engineering systems in buildings to resist seismic actions, it does not define or establish a test method for shake-table testing of non-structural equipment. It does, however, define acceleration limits.
“
“As a result of this successful testing, Fantech is now able to offer a range of fans that have been tested at the highest seismic acceleration limits for both New Zealand and Australia,” says Kerry Dumicich, Fantech Group Engineering Manager.
…tested at the AC156-‘Seismic Certification by Shake-table Testing of Nonstructural highest seismic Components’ is an International Code Council (ICC) standard and is the most internationally-accepted verification method.

Fremantle’s heirloom As one of the largest heritage renewal projects to be undertaken in Western Australia, an iconic wool store in Fremantle has been transformed into industrial-style apartments that reflect the rich history of the site.
Located in the heart of Fremantle, the Dalgety Wool Stores have been a symbol of Western Australia’s wool industry since they were built by J. Hawkins & Son in 1922. Almost 100 years later, the brick and timber buildings have been lovingly restored by boutique developer Match to create 183 luxury, industrial-style apartments. Known as Heirloom by Match, the award-winning heritage renewal project contains a mix of one and two bedroom warehouse apartments that reflect the historic and cultural significance of the building. About 85% of the original building fabric and structures have been retained, including century-old jarrah beams and exposed brickwork, and the building’s unique sawtooth roof structure. Local mechanical services contractor, Triple M Mechanical Services (part of the BSA Group) was engaged by project builder, Built, to provide a mechanical services solution that suited the project’s heritage values while meeting the specifications of a modern HVAC design. This design sees the exhaust for apartment bathrooms and toilets vented at roof level via 60 Twin Gamma centrifugal fans supplied by Fantech’s West Australian Branch, Systemaire. These are connected to risers that double as the builder’s work shafts, which have been properly sealed to prevent air leaks.
According to Triple M Construction Manager, Chris Sawdon, the design called for roof-mounted fans, however due to the acoustic impact on high level apartments and height restrictions for discharge vents at roof level, this design was changed. Instead, lined duct work runs across the roof from the duct work riser penetrations to the fans to absorb fan noise. Where roof fans could not be installed due to the location of the apartment, Fantech Ultimate header box fans were used instead. Additionally, Systemaire supplied a number of JetVent fans to provide effective ventilation in the basement car park. “We use Systemaire for most of our projects here in WA because of the service we receive from them,” said Chris. “The fan selection was pretty straightforward, but Systemaire provided a number of different selections for us to examine to ensure we achieved the best fit for the project.” Heirloom by Match was completed early 2017.

CIBSE’s 30th anniversary honours past leaders
In June, the Australian and New Zealand (ANZ) region of the Chartered Institution of Building Services Engineers (CIBSE) celebrated its 30th Anniversary with a cocktail evening at Melbourne’s Sealife Aquarium.
Members and guests from across its eight chapters celebrated the impact CIBSE has had on promoting the profession of building services engineering in the region since it was first formed in 1987. New Zealand was inaugurated as the region’s sixth chapter in 1992, and as a result membership in the region quickly grew to 320 members. Now in its 30th year, CIBSE ANZ membership has grown to over 650 across Australia and New Zealand. Among the attendees at the 30th Anniversary event were regional committee members, including current ANZ Chair, Paul Angus and current Hong Kong based CIBSE Global President, Peter Y. Wong. The event also coincided with the presentation of the third annual CIBSE ANZ Student and Young Engineer Awards, recently named in honour of two past CIBSE ANZ leaders.
This award was named in honour of Mark who had served as Chair and committee member of both the NSW Chapter and the ANZ Region. “Mark was passionate about building services engineering and an inspiration to his many colleagues and friends, so it was fitting to name this award in his honour,” said current CIBSE Victorian Chapter Chair, Peter Kinsella.
“Jack is held in the highest of esteem and was a real inspiration to all of us at CIBSE,” said Kinsella. “He was passionate about encouraging young engineers to get involved in the industry, and throughout their lives to never be afraid to take a chance. So it was a natural fit that the Young Engineer of the Year award was named in honour of Jack.” We congratulate CIBSE ANZ on their anniversary, and the 2017 award winners.
The Jack Pirie Inspiring Excellence Award – 2017 Young Engineer of the Year was awarded to Simon Green.
