3d-Printed formwork for noise barriers along highway A9

Smarter construction with 3D-printed formwork

As part of the widening and deepening of highway A9 between Badhoevedorp and Holendrecht, new noise barriers were installed to reduce sound pollution for nearby residents. For the foundations of these barriers, we delivered 145 3D-printed formworks used to cast the concrete footings.

This innovative method offers significant advantages on-site. The formworks remain in place after pouring, acting as a permanent shell around the concrete footing—eliminating the need for stripping. This results in immediate time savings and allows multiple footings to be poured simultaneously. Additionally, less skilled labor is required: a crane and an excavator operator are sufficient to install the formworks. The process is simple and efficient: place the reinforcement, position the formwork, backfill the sides, pour the concrete—and done.

Why choose 3D-printed formwork?

• Safe & smart: less heavy lifting and easier on-site assembly
• Fast & efficient: complex shapes produced in a single step
• Flexible: custom solutions without skyrocketing costs

The use of 3D-printed formwork demonstrates how smart technology is driving progress in the construction sector. By choosing this approach, we maintain control over scheduling, costs, and workforce deployment.
