Mechanical Engineering Services Central Coast NSW | Hamilton By Design Co.
Hamilton By Design Co. provides engineer-led mechanical engineering services across the Central Coast, supporting clients in Wyong, Gosford, Tuggerah, and Somersby with practical, site-based engineering and rapid-response project support.
We specialise in design, drafting, fabrication support, and advanced 3D LiDAR scanning, helping construction, food & beverage, and manufacturing businesses upgrade plant, replace critical components, and keep operations running when OEM lead times are too long.
If you need local, responsive mechanical engineers who understand how things are actually built and installed on site, our team is ready to help.

Engineer-Led Mechanical Engineering You Can Rely On
Unlike drafting-only providers, Hamilton By Design is an engineer-led team with in-house machining and fabrication capability. This means your designs are developed with real-world manufacturing and installation in mind โ reducing rework, clashes, and costly site delays.
Our engineers work directly with your site teams, fabricators, and contractors to ensure solutions are practical, compliant, and delivered fast.
We support projects from:
- Concept and feasibility
- Problem-solving and plant modifications
- Upgrades and replacements
- Reverse engineering of existing equipment
- Engineering certification and compliance
All work is completed to Australian and relevant international standards.
Advanced 3D LiDAR Scanning for Accurate Fit-Up
We use engineering-grade 3D LiDAR terrestrial scanning to capture existing plant and structures with high accuracy, allowing us to design components that fit first time.
Our scanning accuracy:
- ยฑ2 mm over 70 metres
- Suitable for structural steel, pipework, conveyors, platforms, and equipment layouts
- Reduces shutdown time and site rework
Scan data is integrated directly into our SolidWorks 3D CAD and FEA workflows, ensuring your designs are based on real-world conditions โ not assumptions or outdated drawings.
