Infrastructure monitoring

Infrastructure and lifelines

Measure what each asset actually experienced, so the decision to reopen a bridge, restart a terminal or prioritise inspections across a network starts on data, not a drive-around.

Trusted on critical assets

One event, dozens of open-or-close calls.

A quake hits a network of assets at once: bridges, wharves, a control tower, pump stations. Closing everything is safe and expensive. Reopening on a hunch is neither. The gap is not knowing what each asset actually took.

Canterbury Seismic instruments the critical points, capturing the motion the structure experienced against a free-field reference on one synchronised clock. Configurable thresholds drive alerts and dry-contact relays the moment they are exceeded, and the record is the evidence an asset owner needs to reopen with confidence or focus inspection where it matters first.

How infrastructure is instrumented, from two units up

Start: two instruments. For a bridge, one at an abutment near free-field and one at mid-span. For a network, one at the single most critical node. Establishes response against ground input.

Standard: the recognised topology. Bridges: abutments, piers and deck spans. Ports and airports: the wharf, terminal or control tower plus a free-field station. Water networks: the key pump stations and treatment plants.

Extended: full array. Multi-span or multi-node arrays on one EQR-C, LVDT on bearings and expansion joints, dry-contact relays into SCADA to trip or isolate, and the record fed to your asset-management system by API for prioritised inspection.

Right-sized protection: IP54 as standard, IP65 where the location is wet or exposed. Marine and outdoor sites specified to suit.

Proven on ports and airports

Our instruments run on port and airport assets and feed owners' own asset-management and response processes, and captured record ground motion in a major earthquake sequence. Supplied, installed and commissioned across New Zealand and Australia by the team that builds the hardware.

Over 20 years in the field

A team instrumenting dams, buildings and ports through real earthquakes since 2003, including the Canterbury sequence.

Support from the engineers

The people who answer your questions designed and built the instruments, so support is fast, competent and direct.

Delivered working

Design, supply, installation and commissioning from one team. You get a working system, not a crate of boxes to integrate.

One record, whole structure

Acceleration, displacement and weather on one synchronised clock, so engineers read the whole structure from a single record.

Fits your response plan

Thresholds in your own labels, with alerts and relays into your systems, so your EAP or TARP starts on a measured value.

Specs you can compare

Every figure comes with its conditions, like 128 dB over 0.1 to 20 Hz, so you can compare instruments like for like.

Your data, your tools

Raw time-series, MiniSEED, CSV and an open API. Run the record in the monitoring and control software you already use.

Transparent pricing

Scope your system and build your budget fast, then talk to us for help achieving your instrumentation goals within budget.

Your data, in your systems

Every instrument records raw time-series acceleration and outputs MiniSEED, CSV and a programmatic HTTPS API, with SeedLink streaming and dry-contact relays into your SCADA or PLC. The web interface is the console, so there is no separate software licence or subscription to run it. Feed the record into your existing dam-monitoring and control systems, or hand it to your engineer's own analysis tools. If you specify instrumentation as a consultant, we supply the measurement layer for your analysis. Your data stays yours.

Infrastructure seismic monitoring questions

How many sensors does a bridge need?

Two is a workable start: one at an abutment near free-field and one at mid-span deck. The recognised topology adds the piers and further deck spans, capturing deck response against ground input. Long or critical bridges extend to a multi-span array on one EQR-C.

Can it monitor a whole network of assets, not just one?

Yes. Instrument the critical nodes across a port, airport or water network, each reporting to the same system, so after an event you can see which asset took the most and inspect there first.

Does it alert automatically?

Yes. Configurable thresholds trigger email and SMS alerts and dry-contact relays into SCADA or a control system the moment measured motion exceeds them.

Do we need a subscription?

No. The instrument's web interface is the console, with no separate software licence. The record streams into your existing asset-management or SCADA systems.

Will it integrate with our asset-management system?

Yes. MiniSEED, CSV and a programmatic HTTPS API, plus dry-contact relays into SCADA or PLC, so the record lands where your inspection decisions are made.

Has it recorded real earthquakes?

Yes. Canterbury Seismic instruments have captured strong ground motion through a major earthquake sequence and run continuously on operating infrastructure.
