The brightest engineers improving our world have been recognised by create’s Australia’s Most Innovative Engineers 2020 awards.
30 engineers were awarded across 10 categories including building & construction, community, utilities, manufacturing & automation and more. The innovations tackle some of the world’s biggest challenges to improve process, safety, sustainability, and efficiency.
“Innovations ranged from macro-scale pieces of infrastructure like railway stations and sports stadiums, to micro-scale technology like atomically thin materials,” says Engineers Australia CEO Dr Bronwyn Evans.
Here’s a closer look at the winners:
Pandanus Leaf-Inspired Cantilevered Stadium Roof
Scott Rathie, Senior Structural Engineer, Arup
Category: Building & Construction
Inspired by the leaf of a pandanus tree, Rathie developed an innovative structural system for Queensland Country Bank Stadium. Rathie first experimented using origami to mimic the behaviour of the leaf and develop it into a workable solution for the stadium roof.
The result was the use of folded plates to stiffen the cantilevered roof instead of using trusses, whilst still providing enough strength to withstand cyclonic winds.
This solution eliminated the need for horizontal ties on the outside of the roof, which allowed the design to satisfy the architectural intent of creating the stadium’s emblematic “kites” cladded on the roof backstays.
Rapid Construction of Central Station Northern Colonnade and Canopy
Michael Chernyavsky, Senior Structural Engineer, Aurecon
Category: Building & Construction
Works to upgrade Sydney’s Central Station for the new metro have continued whilst the station remains almost fully operational, posing a range of construction and engineering challenges.
Chernyavsky and his team engineered a solution to construct the new northern colonnade and canopy over a major thoroughfare without impacting pedestrians entering and exiting Australia’s busiest train station. They designed precast concrete colonnade and steel-framed roof segments that could be rapidly installed during a 4-hour window at night whilst train services have stopped.
“By designing prefab components with four simple connections for rapid on-site installation, we eliminated the need for temporary works or falsework that would otherwise interfere with commuters,” Chernyavsky told This Is Construction.
AI-Powered Camera for Moving Plant Blind Spots
Dr Nathan Kirchner, CTO, Presien
Category: Oil, Gas & Mining
Borne out of Laing O’Rourke’s R&D team, Kirchner and the team at Presien have developed an AI-powered camera with computer vision to identify workers in blind spots of moving plant and equipment.
The camera is connected wirelessly to alarm systems that alert the driver and any other team members of the workers presence through visual, audio and haptic feedback.
Toolbox Spotter has been trained by over 100,000 hours of video footage of worksites to learn how to identify workers and their behaviour.
“Toolbox Spotter sees objects, understands what they are, and what actions to take, seamlessly and in real-time, with no special tags or markers or changes in normal site operating procedures,” the company told This Is Construction.
Robotic Crawler for Rock Tunnel Safety Inspections
Daniel Rechichi, Senior Engineer ROV Design, The Water Corporation
Rechichi developed a battery-powered robotic crawler that can enter tunnels as small as 1.6 m in diameter to conduct a safety assessment prior to worker entry.
The crawler assists crews entering unlined rock tunnels by allowing them to first inspect the tunnel remotely via high quality cameras. It then accompanies crews into the tunnel and provides lights, power, cameras, communications and safety equipment.
The crawler has four-wheel drive, an articulated body for tight cornering and can even clear small boulders and debris with its hydraulic blade.
Optimisation Software to Reduce Energy Use of Building Plant
Iain Stewart, Founder, Exergenics
Category: Building & Construction
Through clever application of machine learning to collect and analyse data Stewart has developed software that creates digital twins of chilled plant. This allows building operators to test various control strategies under a range of scenarios.
An optimisation algorithm extracts the ideal equipment loading for all possible cooling loads and ambient weather conditions.
Combined with IoT (Internet of Things) equipment sensors, the software allows real-time optimisation and performance tracking to reduce CO2 emissions by up to 35,000 kg/year for a typical large office building.
An Automated Model to Identify High-Risk Water Leaks
Nicholas Deeks, Technical Director Hydrology, GHD
Hunter Water Corporation approached GHD looking for a solution to high-pressure water mains leaks. 20 large leaks occur per year risking property damage, road flooding and water service interruption.
Deeks developed a solution by creating software to automatically apply data into multiple scenarios to identify the highest risk areas. By applying the algorithm to spatial data for the entire Hunter region, the equivalent of 57,000 2D models could be created to process 35 billion flood hazard combinations.
This created a database of potential consequences for every water main segment, allowing Hunter Water to identify the high-risk mains that required extra monitoring, renewal or replacement.
“Traditional manual methods used to build each ﬂood model aren’t possible for 57,000 models. So I needed GIS tools and processes to automate the build,” says Deeks.
Dr Shuaiwen Leon Song, Senior Lecturer, University of Sydney
AI-powered accelerator system for cloud-based immersive VR experiences.
Meg Panozzo, Engineer, Arup & Founder, ConnectSTEM
ConnectSTEM is a membership program that facilitates education, collaborative partnerships, and storytelling to address gender imbalance in engineering.

Artificially intelligent system that can identify protected objects, people and symbols, such as hospitals, in near real-time for military operations using computer vision at very high probabilities.
Dr Kyaw Lwin, Overhead Wiring Design & Review Lead, Metro Trains Melbourne
Lwin contributed to several overhead wiring innovations on Melbourne Metro’s Caulfield to Dandenong section.
This included the development of Melbourne’s first 66 kV insulator overhead wiring cantilever arrangement, eliminating the need for protective bonding cables and reducing material usage and installation times.
In addition, Lwin and his team developed the first braced dual anchor mast arrangement, and Melbourne’s first use of a Tensorex spring tensioning anchor system for overhead catenary and contact wires, resulting in a sturdy and compact anchor assembly requiring no heavy weights or guide rods.
