Utility tunnels and underground space where GPS never reaches

The problem on site

Underground assets are inspected on a schedule that has nothing to do with when they fail. A cover lifts, a level rises, gas accumulates — and nobody knows until somebody complains or something collapses.

Inside a tunnel there is no GPS, often no mobile signal, and standing water for half the year. Consumer IoT hardware does not survive there, and battery life measured in months makes the maintenance burden worse than the problem.

What we deploy

We instrument the points that predict failure: covers, levels, gas, vibration and access. Devices are IP68 where they sit in water, and they buffer locally so a week offline loses nothing.

For inspection we use robots and push cameras that record position along the run, so a defect found in month nine can be compared with the same metre in month twenty-one.

Devices typically in scope

• Solar Smart Manhole Cover — cover position, tilt and unauthorized-opening detection
• Smart Manhole Monitoring — gas, water level and temperature beneath the cover
• Solar Water Level Monitor — level sensing for drains, channels and stormwater
• Pipeline Inspection Robot — CCTV crawler with distance-referenced defect logging
• QV Push Camera — quick-view pole camera for shallow or restricted laterals
• Structural Monitoring — vibration and displacement sensing for tunnel linings
• Inspection Robot — tracked robot for gallery patrols and thermal screening
• Smart Access Control — controlled entry with audit trail for restricted chambers

What we need from you

• Route drawings or a plan showing chamber and cover locations
• Whether a wired backbone exists inside the tunnel
• Which parameters trigger an intervention today
• Confined-space entry rules your teams work under

What we do not do

• Carry out confined-space entry ourselves
• Replace a structural engineer's condition assessment — we supply data, not a verdict
