The first 6 Star Green Star rating for a public building in Western Australia was for the Mills Park community facility in the City of Gosnells in the south-eastern suburbs of Perth.
The sustainability lead for the project was Michael Thompson from AECOM. He said a practical approach to sustainability was pivotal to the rating, with the City adopting a large number of low-cost initiatives.
“This is a publicly-funded project, so everything we did needed to represent good value,” Thompson says. “Rather than trying to force expensive and over-engineered systems into the design, we went for initiatives with synergy, initiatives that work well in a building like this one. There’s a lot to be said for getting the basics right.”
The facility uses low-energy LED lighting and a smart, responsive air conditioning system. In addition, it will have
a 30 kW solar array, capable of generating up to 15% of the building’s electricity requirement annually. Thompson says they came up with a building with eeffciencies that could save the City of Gosnells up to $145,000.

The Singapore Sports Hub features a number of sports venues including a 55,000 seat stadium with the world’s largest free span dome.
Mike King was the driving force behind the roof, which comprises a retractable roof in two symmetrical halves, supported by a fixed dome roof.
The fixed roof structure comprises a series of arch-shaped steel trusses in a dome form, varying in depth from 5 m at the centre to 2.5 m at the base, and a post-tensioned concrete ring beam support.
The fixed roof directly supports the retractable roof via a series of ‘bogies’ running on the parallel ‘runway trusses’ that span perpendicular to the pitch axis.
Anoop Kumar Arya has invented a new type of footing called ‘Soil Anchor Footing’, which can be used to support steel or concrete columns, walls, light posts, sign posts, electrical substation equipment, pipe support, railway infrastructure, light industrial structure, etc.
This footing is lightweight, requires minimum excavation and soil disposal, is economical, environmentallyfriendly, and easy to construct.
The footing can be cast in-situ, completely pre-cast type, or partly pre-cast type. In the cast in-situ type, 150-350 mm depth of ground is excavated so as to accommodate the top slab.
Deformed steel bars of 12 mm to 36 mm size, 0.3 m to 2 m long, are then pushed into the ground in accordance with a predetermined grid pattern. A concrete slab of about 200-400 mm thick is then cast on top of the bars so as to effectively encase all of the bars, and hold down bolts which can also be chemically or mechanically secured over the slab.
Arya has led patent applications in Australia, USA and India.

Nick Birks led the deconstruction of the derrick, 57.5 m above the drill floor in the North West Shelf Project in Western Australia.
The innovation was the concept design and detailed engineering of the method to use a relatively small KBAD crane.
The lift involving the most steps was the removal of the 900 kg monorail at the top of the derrick on 1 August 2014.
This was lowered onto the ‘water table beams’ using two manual chain hoists and lever hoists to thread it sideways.
It was then skidded into a position where it could be lifted with the Hiab Sea Crane and lowered 50 m to the drill floor.
Matthew Linegar is the Technical Manager of the team responsible for the Structural Design of Australia’s First Engineered Timber Commercial Building, International House at Barangaroo, Sydney, expected to be completed in late 2016.
The six-storey structure comprises a glue laminated timber frame, cross laminated timber floor and recycled ironbark. Using these engineered timbers opens the project to a range of environmental, social and economical sustainable benefits.
Linegar turned to engineered timber as there was a tight delivery timeframe combined with a desire for an appropriately innovative entrance to the precinct.
Andrew Harris joined Laing O’Rourke in 2011 to help set up and lead a centre of excellence in strategic innovation.
The Engineering Excellence Group is a specialised innovation lab designed to promote positive change in the construction industry.
The multidisciplinary group has doctoral level expertise in the sciences, engineering, arts, and more. Its role is to identify and develop strategically important or disruptive innovations to improve safety, quality, productivity and profitability.
“They have invented … a hardhat that measures your health in real time.”
They have invented, commercialised and deployed innovations in virtual and augmented reality, construction-scale 3D printing, intelligent infrastructure (bridges that ‘talk’ to the trains running over them), next-generation health and safety technology (a hardhat that measures your health in real time and warns you if you are in danger), and the world’s first relocatable hybrid solar-diesel system.
