Reducing Labor Time with Custom Metal Fabrication for Highway Projects
Engineering Custom Assemblies for Interstate 265 & 65
We engineered a direct bolt-in stainless steel assembly for scalable production and to reduce field installation time.
Our shop brings together one of the largest waterjet tables in the region, a responsive in-house design team for rapid drawing revisions, and full-service fabrication capabilities across a wide range of metals and construction materials.
That combination of engineering agility, production capacity, and consistent communication is why Transurban chose to partner with us on this project.
The Challenge
Transurban needed a new fixture that would integrate seamlessly with their stainless steel electrical boxes. The material needed to match both visually and structurally while maintaining long-term durability in the elements.
We sourced 14GA 304L stainless steel, a highly corrosion-resistant alloy, ideal for heavy-gauge components requiring strong weld joints without post-weld annealing.
After reviewing their initial drawings, our waterjet technician re-engineered the design to simplify both fabrication and installation. The updated fixture became a direct bolt-in solution, significantly reducing labor time on-site. We also integrated ground lugs directly into the bracket, eliminating an additional installation step in their workflow.

The Scope
What began as a one-month production request—30 modified camera mounts and 24 internal electrical box brackets—expanded into a six-month partnership. During that time, we delivered:
- 555 Camera Mounts
- 545 Z Brackets
- 376 Posts
- 24 Additional Custom Fixtures
Forming small flat plates into precise stainless brackets presented a production challenge. To ensure consistency and efficiency, we designed and machined a custom die in-house for our press brake, enabling accurate 90-degree bends in 14GA 304L polished stainless steel.
This in-house tooling streamlined production and ensured repeatable quality across all fabricated components.
The Impact
Redesigning the fixture into a direct bolt-in solution reduced on-site labor and simplified their electrical box assembly process. The consistent material match ensured seamless integration with existing components, preserving both structural integrity and visual continuity across the project.
Our ability to adapt designs quickly, solve production challenges in-house, and deliver high volumes within a tight timeline helped keep their construction schedule on track.
The result was fewer installation steps, reduced field labor, dependable product consistency, and a fabrication partner capable of supporting both immediate project demands and future infrastructure needs. At Heumann Environmental, we don’t just build fixtures, we engineer efficiencies that keep projects moving.
