Infrastructure isn’t built by projects. It’s built by repeatable systems.

Back on site with BBV on HS2 near Birmingham — where this system is being deployed across a 16-mile stretch of viaduct sidewalls.

At that scale, the challenge isn’t casting a wall.
It’s doing it hundreds of times — consistently, safely, within a live structure.

Space is tight.
Access is restricted.

Conventional approaches — ground-based cranage, winching, external handling — quickly become inefficient.

So the solution had to be engineered differently.

Working with the client and Forkast Engineering, DEMA supported the development and delivery of a system tailored to these constraints:

✦ Deck-handled formwork using a side-shift forklift — removing ground-based lifting
✦ Pincer lifting for controlled release and precise lateral movement
✦ Single- and double-wall capability across phases
✦ Heavy-duty steel units designed for repeat cycles at infrastructure scale

This isn’t just about forming concrete.

It’s about making engineered solutions work in real site conditions —
where constraints are constant, and every cycle matters.

Because over 16 miles, inefficiencies don’t stay small.

They multiply.
