3D Monitoring & Deformation Surveys
Real-time precision monitoring — keeping your assets and infrastructure safe, 24/7.

Smart monitoring starts with smart technology. From Triaxial Tilt to Crack Sensor Nodes, we offer a range of wireless solutions to collect and analyse data — delivering stable, precise, and highly user-friendly data anywhere in the world from your geotechnical and structural monitoring installations. Our proven, easy-to-deploy, long-life systems are the benchmark for wireless remote monitoring solutions. Key Benefits: ✔ High-precision remote monitoring ✔ Easy, rapid deployment ✔ Proven long-life wireless systems

Keeping rail infrastructure safe is at the heart of what we do. We are experienced in providing specialist track monitoring surveys for embankment, UTX, piling works, and any construction adjacent to track in accordance with NR/L2/CIV177. We deploy either a manual or automated system, set to alarm if trigger values are reached. We also monitor other Network Rail assets and structures. For permanent monitoring, our systems provide 24/7 remote operation, continuous monitoring, real-time measurement data, and TRK001 Track Inspections. Changes in gauge, geometry, and position of the track are determined in accordance with NR/L2/CIV/177. Risk scoring matrices and Track Monitoring Plans (TMP) can also be produced for projects by our Competent Rail Engineer (CRE). Key Benefits: ✔ Compliance & risk mitigation ✔ 24/7 real-time insight ✔ Flexible high-precision monitoring

Before any works begin, getting an accurate baseline is essential. We undertake optical baseline surveys prior to commencement of any planned works, recording Easting, Northing, and Elevation coordinates, as well as physical cant and gauge readings — including visual TRK001 inspections. Targets are securely fixed to the web of each rail at 3m intervals, extending 30m outside any disturbed area within the Zone of Influence, surveyed on a local network grid. Key Benefits: ✔ High-resolution fixed-point monitoring ✔ Comprehensive track coverage ✔ Pre-works baseline accuracy

When your project demands round-the-clock precision, our Automatic Total Station systems deliver. We deploy total stations with up to 0.5" accuracy for 3D measurement and imaging — measuring absolute XYZ railway geometry, horizontal alignment, vertical position, gauge, cant, and twist. Data is transmitted live to monitoring software and pushed to online analysis and visualisation platforms. Automated reports are generated and sent daily to the client at an appropriate frequency. Trigger values are configured to send instant alerts by email and SMS if values are breached. Additional support and analysis is provided by our in-house nominated CRE, with actions reviewed and mitigations actioned promptly. Over long-term projects, significant cost savings can be achieved. Key Benefits: ✔ High-precision automated measurement ✔ Real-time data & alerting system ✔ Fully managed reporting & expert support

Dynamic voiding under load can introduce dynamic twist faults and raise derailment concerns. We manage this through traditional methods under line blockages and track inspection using void meters — as well as remote Network void meters that provide instant 24/7 monitoring data through an online web interface, without the need for personnel to access the line during normal operation. Key Benefits: ✔ Improved track safety under load ✔ Reduced need for line access ✔ Continuous real-time visibility

As rail networks face increasing temperature challenges, CRT management has never been more important. Where projects affect the track system and require CRT management, we offer CRT Assessments, CRT Watchman, and CRT Coordinator services under CRT Management Plan NR/L3/TRK/7012 & NR/L2/TRK/001/mod14. Remote Smart Sensors provide 24/7 live data, graphs, and alerts — helping manage the risk of rail buckle and derailment as SFT values are upgraded across the network. Key Benefits: ✔ Enhanced rail safety in high temperatures ✔ Continuous remote monitoring capability ✔ Flexible, cost-effective compliance support

Your data security is our priority. All monitoring data is delivered through secure, antivirus-protected data exchange services. Our SharePoint platform is Network Rail approved and actively in use with Balfour Beatty East & West, using Bentley ProjectWise in accordance with the Network Rail Wales & Western BIM Strategy — ensuring seamless, compliant data management from start to finish.
