Projects
Widening A27 Houten – Hooipolder
Houten – Breda, Netherlands
Project duration: 2024 – 2032
For the widening of the A27 between Houten and Breda, extensive monitoring was carried out to quantify soil settlement and long-term residual deformation over a twenty-year horizon. The same monitoring system also tracked the Merwede Bridge in Gorinchem and a high-pressure water pipeline. This integrated network delivered continuous, consistent measurements across all critical infrastructure elements.
The project provided early and reliable insight into settlement and object movement, enabling faster execution and reducing liability risks.
Project Purpose
The project aimed to identify soil settlement, compaction and object movement at an early stage, ensuring optimal planning and execution of the road works. By monitoring multiple infrastructure assets through a unified system, detailed insight was obtained into subsurface processes as well as the structural behavior of the bridge and pipeline.
Implemented Solution
Settlement rods and Locator One units were deployed to achieve high-precision positioning of soil layers, structures and pipeline routes. All sensors reported through the same platform, supported by multiple reference stations. Measurement frequency was configured per sub-area, ranging from one to twenty-four measurements per day. This provided a consistent and timely picture of current and future settlement.
