Range of Services
Custom Engineering & Fabrication Services
From concept through to fabrication, BH Engineering delivers practical, high-performance solutions built for real-world environments.
Based in Bunbury, Western Australia, BH Engineering supports mining, civil, industrial, automotive and infrastructure projects with purpose-built components and fabrication solutions.
Whether you need a concept turned into a working design, precision fabrication, or specialised welding, our team brings practical engineering knowledge and hands-on workshop capability together under one roof.
Every successful project starts with a clear and accurate design. BH Engineering provides professional design and drafting services that transform ideas, sketches or existing components into detailed engineering models ready for fabrication.
Using modern CAD and 3D modelling tools, we ensure every dimension, connection and material specification is properly defined before fabrication begins.
This reduces costly errors, speeds up production, and ensures the finished product performs exactly as intended.
Typical services include
• 3D modelling and visualisation
• CAD design and drafting
• Concept development
• Fabrication drawings

The Innovation Hub is where ideas move from concept to real-world solutions.
BH Engineering supports inventors, engineers, and businesses who need help developing new products, improving existing equipment, or solving technical fabrication challenges.
By combining design expertise, fabrication capability, and modern prototyping technologies, we help turn concepts into working prototypes ready for testing and production.
Innovation capabilities
• Product concept development
• Prototype fabrication
• 3D printing for concept models
• Design refinement
• Rapid prototyping
• Custom engineering solutions
Who this is for
• Start ups developing physical products
• Businesses improving equipment or tools
• Industrial problem solving
• Custom engineering solutions
3D scanning allows existing components, parts and equipment to be digitally captured with extremely high accuracy.
This technology is ideal when original design drawings are unavailable or when components need to be replicated, modified or integrated into new designs.
By creating precise digital models of real-world objects, BH Engineering can quickly move from physical component to digital engineering file.
Benefits of 3D scanning
• Accurate measurement of complex shapes
• Faster reverse engineering workflows
• Digital models for CAD design
• Improved fitment and compatibility
• Reduced manual measurement errors
Typical uses
• Replicating worn or obsolete parts
• Capturing complex industrial components
• Modifying existing equipment
• Integrating new components into existing systems
In many industries, parts fail long after the original manufacturer drawings are lost or unavailable. Reverse engineering allows those components to be recreated accurately so operations can continue.
Using 3D scanning, measurement techniques and CAD modelling, BH Engineering can analyse existing parts and produce detailed digital models ready for fabrication.
This service is particularly valuable for mining, industrial and legacy equipment where replacement parts may be difficult to source.
Reverse engineering services
• Component analysis and measurement
• 3D scanning and modelling
• CAD reconstruction
• Fabrication-ready drawings
• Replacement part development
Common scenarios
• Obsolete equipment parts
• Machinery upgrades
• Rebuilding worn components
• Improving existing designs
Need Something Designed, Built, or Modified?
Lightbulb ideas, chook scratchings and napkin notes
Whether you have a rough concept, technical drawings, or an existing component that needs modification, BH Engineering can help bring the solution to life.
Our team works closely with clients to understand the application, environment and performance requirements before designing and fabricating the right solution.
