When heavy piling, demolition, or tunnelling happens close to existing structures, managing ground vibration is vital to prevent structural damage and keep local communities on side. To keep sites compliant and data transparent, reliable monitoring is essential. At PQS Survey, advanced environmental and vibration solutions are a core part of our hire fleet. I caught up with John Hutchinson, our internal product champion for environmental monitoring, to talk about the Sigicom INFRA C22 Wireless Triaxial Vibration Monitor and why it has become an indispensable asset for many PQS customers.
Zero Wires, Maximum Freedom
Simon Lunt (PQS): John, traditional vibration monitors can be cumbersome with long cable runs across active sites. How does the Sigicom INFRA C22 change things for site teams?
John Hutchinson (PQS): “It is completely wireless. The C22 packs a triaxial geophone, data logger, and a 4G cellular modem into a single, compact unit small enough to fit in your hand. Because there are no messy cables to run, our hire customers can mount it on site hoardings or structures and be up and running in minutes.”
Long-Term Battery Performance on Remote Sites
Simon: Site managers hate units that constantly need power attention or battery swaps. How does the C22 hold up over extended project timelines?
John Hutchinson: “Battery longevity is a massive win here. It delivers up to four months of continuous, uninterrupted monitoring on a single charge. That means fewer site visits, lower maintenance overhead, and total peace of mind for medium to long-term civil engineering projects.”
Meeting UK Legislation and Protecting Local Residents
Simon: Why do our hire customers rely so heavily on these monitors on-site? Is it purely for compliance, or is it about wider community management?
John Hutchinson: “It is a mix of both. Contractors use them to strictly respect UK legislation requirements and prove their vibration levels remain fully compliant with standards like BS 7385. But just as importantly, it ensures that local works do not unnecessarily disturb local residents. Having indisputable data protects you from complaints and keeps community relations smooth.”
Instant Remote Alerts via INFRA Net
Simon: How does the system handle vibration alerts?
John Hutchinson: “It streams data directly to the INFRA Net cloud platform. If vibration thresholds are breached, the system automatically triggers instant SMS or email alerts to key project personnel. You can check live graphs, adjust settings remotely, and download compliance reports without ever stepping foot back on site.”

John’s Top Tip: Mount Firmly and Early
John Hutchinson: “Always mount the unit securely to a rigid surface or dedicated pier close to the asset you are protecting before heavy breaking or piling begins. Getting your baseline readings established early ensures your compliance record is bulletproof from day one.”
