From measurement to review
How Ackcio fits your monitoring setup
The instrument output, reading interval, site layout and data destination determine the system configuration.
Match the interface
Connect supported instrument outputs to the appropriate acquisition node. Check the exact sensor model, excitation, output and power needs.
Analogue Nodes Vibrating Wire Nodes Digital NodeCollect the readings
The gateway receives data from the Beam network. Plan its location, power and backhaul around the bridge and the required workflow.
Explore the GatewayReview and integrate
Manage the network and sensor data through Snape. Send readings to compatible third-party platforms or your own software using supported API or FTP integrations. Confirm the data format, destination and access requirements for your project.
Explore SnapeWork with the instruments you use
Select the node by the instrument’s electrical output: analogue, vibrating wire or a supported digital interface. The instrument category alone does not determine compatibility.
Check output type, excitation, power, channel requirements and reading interval for each model. Ackcio sensors and compatible third-party instruments can form part of the same monitoring plan.
Fit your existing data workflow
Choose where engineers will review the readings: Snape, a compatible monitoring platform or an internal system. Plan the gateway connection and integration around that destination.
Confirm supported interfaces and data formats with the project team before specifying the system.
The wireless differentiator
Self-Healing Mesh
Bridge geometry and site conditions can affect radio links. Ackcio Beam automatically selects communication paths, using alternative routes where available.
This is radio-path resilience. It does not remove the need to maintain instruments, sensor cables or power supplies.
How Ackcio Mesh worksWhat can you monitor?
Six areas. A connected view.
Explore the bridge from the surrounding environment to the quality of the data itself. Each area combines measurable parameters, typical instruments and a route to the right products.
Monitoring area 01
River, scour & weather
How are river conditions and weather changing around the bridge?
Connect changing site conditions with the bridge’s response. Specify environmental measurements separately from structural measurements.
- Water level
- Water-level instruments record changes around the bridge piers.
- Wind and temperature
- Anemometers, weather stations and temperature sensors provide environmental context.
- Scour assessment
- Use project-specific scour instrumentation or surveys. Structural tilt can provide additional context, but is not a direct scour measurement.
Measurement considerations
Water-level and weather instruments shown are supported instrument categories; they are not presented as Ackcio-manufactured products.
Monitoring area 02
Piers, abutments & approaches
Are the supports tilting, or is the surrounding ground displacing?
Review changes in structural orientation and the displacement of adjacent ground using measurements suited to each location.
- Tilt and rotation
- Tiltmeters measure angular change on piers and abutments.
- Settlement and heave
- Suitable settlement instrumentation measures vertical displacement at the approach or foundation.
- Subsurface displacement
- An appropriately installed in-place array can help characterise the displacement profile around the asset.
Measurement considerations
A tiltmeter measures angle; it does not directly measure settlement. Array installation and orientation determine the displacement being measured.
Monitoring area 03
Deck deflection & vibration
How is the deck responding to traffic and changing loads?
Understand how the deck responds to traffic, project activities and changes in loading. Define the response you need before selecting the acquisition system.
- Deck deflection
- Suitable displacement instruments track changes at specified points and reference locations.
- Vibration
- Appropriate vibration sensors and acquisition equipment capture the required dynamic response.
- Temperature context
- Temperature measurements help engineers interpret changes alongside environmental conditions.
Relevant Ackcio products
Discuss measurement requirementsMeasurement considerations
Dynamic measurements need a sampling rate, bandwidth and synchronisation plan appropriate to the engineering question.
Monitoring area 04
Strain in girders, cables & stays
How are selected structural members responding to load?
Measure local structural response at selected members. Interpret readings using the bridge design, installation details and the engineering model.
- Strain in steel or concrete
- Surface, embedment or rebar strain gauges measure strain at the installed location.
- Load at selected connections
- Suitable load cells may be specified for the particular load path and installation.
- Thermal response
- Temperature readings support the interpretation of strain and load changes.
Measurement considerations
Strain is not a direct measure of stress without the appropriate material assumptions and engineering interpretation.
Monitoring area 05
Bearings, joints & cracks
Are cracks and joints opening or closing, and are bearings displacing?
Follow opening, closing and relative displacement at selected details, including during repairs or strengthening works.
- Crack width
- Crackmeters measure opening and closing across an installed gauge length.
- Joint opening and closing
- Suitable joint or displacement sensors measure relative change at the selected joint.
- Bearing displacement
- Displacement instruments record relative displacement at specified bearing locations.
Measurement considerations
Choose the node from the actual instrument output and electrical requirements. The sensor model’s output determines the acquisition interface.
Monitoring area 06
Data & network health
Does an unusual reading reflect structural change or a measurement issue?
A measurement is more useful when the team can also review how it was acquired. Keep the instrument record and the communication network in view.
- Device and network status
- Review available battery and communication status information.
- Missing or unusual readings
- Investigate gaps and unexpected changes alongside site events and instrument checks.
- Self-Healing Mesh
- The Beam network automatically selects communication paths as radio conditions change, using alternative paths where available.
Measurement considerations
Radio rerouting does not repair a cut sensor cable or a failed instrument. Physical faults still need inspection and maintenance.
Between inspections
The bridge keeps responding.
Your evidence should keep building.
Inspections provide essential observations. Instrument readings add a record of selected parameters between visits, helping engineers investigate changes in context.
Internal deterioration
Changes within cables and structural members may need targeted instrumentation.
Corrosion and ageing
Measurements add context when reviewing an ageing asset’s condition.
Changing loads
Understand the response to traffic and other project-specific loading conditions.
Construction and repairs
Track selected parameters as construction, strengthening or rehabilitation progresses.
Illustrative bridge scenarios.
Periodic observations
Visits and inspections record conditions at particular times. Access arrangements can make additional readings difficult to obtain.
A configured measurement record
Wireless acquisition brings readings from suitable instruments to a gateway at the project’s configured intervals. Engineers can review trends alongside inspections and site events.
Start with your asset
Different bridges.
A focused monitoring plan.
Choose the parameters that answer a defined engineering question. The same layout does not fit every bridge.
River bridges
Coordinate environmental observations with foundation and structural measurements.
Viaducts
Select pier tilt and displacement measurements around access constraints.
Cable-stayed bridges
Define the strain or load question for the relevant members and connections.
Rail bridges
Plan measurements around the asset, operational windows and access requirements.
Rehabilitation
Track cracks and relative displacement alongside repair activities.
Ageing structures
Build a record to support inspections and engineering assessment.
Define the question
Identify the asset, engineering concern, required parameters and the people responsible for reviewing the data.
Plan the deployment
Select the instruments, acquisition method and network layout. Agree access, power, installation and commissioning requirements with the project team.
Review, then extend
Validate readings and the response workflow before extending the system. Use actual project costs and access requirements to assess the business case.
Build a project-specific business case
Consider site visits, access arrangements, installation, connectivity and ongoing maintenance. Savings depend on the actual monitoring scope.
Keep engineering decisions with the team
Monitoring supports assessment. Inspection, engineering interpretation and the agreed action plan remain essential.
Common questions
Before you specify a system
Can we connect instruments we already use?
Potentially. Match each sensor’s output, excitation, electrical and sampling requirements to the supported acquisition interface. The instrument name alone does not establish compatibility.
Does wireless monitoring remove every cable?
No. Some instruments connect to a local node by cable. In a Beam deployment, Mesh carries data wirelessly between nodes and the gateway. Local sensor connections still require protection and maintenance.
Does every measurement use the same sampling interval?
No. The monitoring objective and instrument determine the interval and acquisition requirements. Dynamic vibration measurements require separate technical validation.
Can monitoring replace bridge inspections?
Instrument readings complement inspections and engineering assessment. The bridge owner and engineering team define how readings inform the asset’s response plan.
