About Us
Certified Mechanical & Structural Engineering Consultants
Geometric Design Engineering (GDE) is a premier Melbourne-based engineering consultancy dedicated to delivering robust mechanical and structural solutions. We specialise in transforming complex industrial challenges into certified, code-compliant, workshop-ready realities. Grounded in rigorous engineering analysis, advanced Finite Element Analysis (FEA), and precise hand calculations, we ensure every project meets strict Australian Standards. We partner closely with fabricators, manufacturers, commercial developers, and heavy industries including specialised transport and weighbridge systems. Through these partnerships, we provide the precise technical foundation required for absolute structural integrity and manufacturing efficiency.
Our Team
Eddie Khan
Principal Engineer
MIEAust | CPEng | NER
Eddie founded Geometric Design Engineering and leads its mechanical and structural engineering work. He holds a Bachelor of Mechanical Engineering (Honours) from Swinburne University and is a Chartered Professional Engineer. Over the past eight years he has built a deep working knowledge of manufacturing, structural steel and reinforced concrete footings, with a strong grounding in engineering design, hand calculations and finite element analysis. That hands-on background shapes how GDE works: practical, buildable designs backed by clear calculations and a real understanding of how things are fabricated and used. Clients deal directly with Eddie from the first conversation through to sign-off.
Bodo Siemienowicz
Senior Mechanical & Structural Engineer (Associate)
MIEAust | CPEng | NER | RPEV | RPEQ
Bodo brings more than 50 years of engineering experience to the GDE team. A graduate of RMIT University, he has experience across mechanical, civil and structural engineering and is a registered professional engineer in both Victoria and Queensland. Over his career he has designed and delivered a wide range of projects, with deep expertise in structural steel, reinforced concrete and foundation design. At GDE, Bodo collaborates on complex mechanical and structural projects and provides independent certification where state registration is required, giving clients the added assurance of two experienced engineers on their work.

Your Partner in Industrial Advancement
We deliver advanced mechanical and structural solutions engineered to withstand the most demanding operational environments. From heavy vehicle components to complex industrial machinery, our designs undergo rigorous virtual stress testing and compliance verification. We ensure every asset is optimized for maximum structural integrity, durability, and seamless manufacturing efficiency.
Our engineering practice is built on first principles analysis to evaluate stress, shear forces, bending moments, and deflections under maximum loading conditions. We integrate critical data from the site geotechnical soil report to precisely calculate foundation requirements, concrete reinforcement configurations, and structural footing capacities. By balancing axial, lateral, and torsional loads, we mathematically verify the structural integrity of every mechanical and civil component. This rigorous analytical approach guarantees that all steelwork, connections, and concrete elements comply fully with Australian Standards prior to workshop execution.
