Engineering Above the Lanes: How Amediate Delivered Airport Gantries Without Disruption

When critical infrastructure needs to go up—fast, safe, and with zero margin for error—Amediate Engineering steps in to make it simple.

As part of a major upgrade to accessways at Auckland International Airport, Amediate was engaged to fabricate, and install several large-format motorway gantries. These structures now carry directional signage across busy arterial lanes used by thousands of airport customers daily. “If you have been to the airport, you have driven under our work…”

What made this project different?
Everything had to be done without disrupting airport operations.

Working closely with the client’s delivery team, our engineers approached the project with a simple goal: make it look easy, even when it’s not. The gantries—each extending the full width of multi-lane roads—were fabricated in our East Tāmaki facility using precision welding, robotic prep, and stringent dimensional checks to ensure seamless installation.

But the real challenge was the install.

Rather than taking a piecemeal approach, we simplified the process by pre-assembling each gantry into single-lift sections. This not only reduced install time but allowed our site crews to perform each lift during carefully planned overnight windows, avoiding disruption to daytime traffic and maintaining safety for both workers and the public.

With cranage, traffic management, and site crews working in tight coordination, every gantry was installed exactly to plan—with no rework, no overruns, and no operational impact to the airport or its customers.

This project is a clear example of what Amediate brings to the table:
– Smart sequencing that reduces onsite hours
– Heavy lifting capability paired with real-world planning
– Simplifying high-risk infrastructure projects for smooth delivery

At Amediate Engineering, we don’t just build steel—we build trust by making complex projects straightforward and deliverable.
