Heavy Civil Infrastructure

Asset Intelligence for Bridges, Tunnels & Heavy Civil Infrastructure

From bridge bearing to tunnel ventilation. From road pavement to fire safety system.

AssetStack connects structural condition, mechanical systems, safety-critical equipment and inspection workflows into a single intelligence platform, so infrastructure owners and contractors can move from fragmented inspection reports to defensible, regulator-ready asset decisions.

The Industry Challenge

Structures, Tunnels and Safety Systems. Managed in Silos

Australia's heavy civil infrastructure is ageing, inspected constantly, and governed by multiple overlapping standards, yet the data lives in disconnected systems. Bridge inspections in one database, tunnel safety systems in another, pavement condition in a third, and capital planning in a spreadsheet that hasn't been updated since the last consultant left.

  • 50,000+

    Public Road Bridges

    Across Australia managed by 800+ organisations. State Road Authorities manage 20,000+ bridges; local councils manage the remaining 30,000. Each with their own inspection cycles, condition ratings and deteriorating funding positions.

  • Level 1, 2 and 3

    Inspection Complexity

    Level 2 visual inspections are the common basis for forward works programming, but the data often lives in PDF reports with no link to photos, no connection to capital plans, and no update mechanism when the next inspection cycle arrives.

  • 8 Tunnels

    In One Network Alone

    Ventia maintains 670km of roads, 201 bridges and 8 tunnels in NSW Sydney South. Each tunnel carries mechanical ventilation, fire detection, emergency lighting, drainage and ITS, all with separate maintenance regimes and proof-test intervals.

The compounding problem: Bridge condition data sits in consultant PDFs. Tunnel safety systems (ventilation, fire suppression, emergency lighting) are maintained on separate schedules with no connection to structural condition. Pavement resurfacing is planned by age, not by actual ride quality or traffic loading. And when a major weather event hits, there's no integrated view of which structures, tunnels and safety systems are compromised, because the data was never connected in the first place.

Who It's For

Built for Infrastructure Owners and the Contractors Who Maintain Them

AssetStack serves both the asset owners who need defensible condition data and capital plans, and the engineering contractors who need consistent, scalable asset intelligence across massive, multi-site portfolios.

For Infrastructure Owners & Network Operators

Toll road operators, state road authorities, local councils and transport agencies who need to understand the condition of bridges, tunnels, pavements and safety systems across their network, with defensible data for regulator submissions, capital planning and duty-of-care compliance.

  • Integrated view of structures, tunnels and safety systems
  • Condition-informed capital planning for forward works
  • ARRB-aligned inspection data with photo evidence
  • Tunnel safety system compliance tracking (ventilation, fire, lighting)
  • Post-event damage assessment and recovery prioritisation

For Engineering & Maintenance Contractors

Organisations delivering long-term road network maintenance, tunnel operations and structural inspections across multiple contracts, who need a consistent digital asset register, visual reporting and condition intelligence that scales from 201 bridges and 8 tunnels to thousands of kilometres of network.

  • Consistent asset hierarchy across all client portfolios
  • 3D digital twins for complex structures and tunnel environments
  • Level 1, 2 and 3 inspection management with audit trails
  • Shutdown maintenance planning and closure coordination
  • Differentiated service offering beyond reactive maintenance

Capabilities

Inspect. Model. Maintain. Verify.

Four integrated capability groups that close the gap between bridge inspection data, tunnel safety compliance and defensible capital decisions, so every ARRB submission, tunnel closure plan and council forward works programme is backed by traceable evidence.

Inspect

Structured inspection and condition assessment

  • ARRB-Aligned Inspection Management

    Manage Level 1 (routine), Level 2 (detailed visual) and Level 3 (structural investigation) inspections with structured data capture, photo evidence and condition grading, all linked to the individual bridge element or tunnel system, not just the structure ID.

  • Component-Level Condition Register

    Bridge: deck, superstructure, substructure, bearings, joints, parapets, drainage, approach. Tunnel: lining, pavement, ventilation, lighting, fire suppression, drainage, ITS, emergency systems. Each element carries its own condition grade, defect log and intervention history.

  • Photo-Evidence & Defect Logging

    Every inspection photograph is geotagged, dated and linked to the specific asset element it depicts. Defects are logged with location, severity, recommended action and target date, creating an audit trail from first observation through to repair verification.

Model

Digital twin and structural intelligence

  • 3D Digital Twin for Structures

    Navigate a digital representation of a bridge, tunnel or interchange and select individual elements to access inspection records, condition grades and maintenance history. Understand physical relationships between structural components without relying on drawing numbers.

  • Structural Health Monitoring Integration

    Connect sensor data (strain gauges, accelerometers, displacement sensors, corrosion probes) to the digital twin. Monitor load distribution, dynamic response and deterioration trends over time, with alerts when measured behaviour deviates from the baseline model.

  • Spatial & Corridor Intelligence

    For linear infrastructure, organise asset information across geographically dispersed networks. Identify clusters of deterioration, recurring defects and climate-exposed structures in their physical and corridor context.

Maintain

Tunnel safety, pavement and structural maintenance

  • Tunnel Safety System Compliance

    Track mechanical ventilation, fire detection, emergency lighting, smoke extraction, water suppression and drainage systems against their performance standards, proof-test intervals and regulatory requirements. Overdue tests and bypassed systems surface before they become safety incidents.

  • Shutdown Maintenance Planning

    Program quarterly tunnel closures, bridge lane restrictions and pavement rehabilitation within existing closure regimes, avoiding additional disruption. Coordinate structural, mechanical, electrical and pavement works in a single integrated schedule.

  • Pavement & Ride Quality Management

    Track pavement condition, roughness, rutting and skid resistance across the network. Link ride quality data to traffic loading, climate exposure and maintenance history, so resurfacing is prioritised by actual condition and consequence, not just age.

Verify

Capital planning and verified outcomes

  • Dynamic Forward Works Programme

    Model bridge rehabilitation, tunnel refurbishment and pavement replacement based on actual condition, traffic loading and safety risk, not static age-based schedules. When a new Level 2 inspection identifies critical defects, the forward works program updates automatically.

  • Scenario Modelling & Capital Forecasting

    Model Premium, Balanced and Must-Do funding scenarios for structures, tunnels and pavements. See exactly what each service level costs and what deferral does to your renewal backlog, ready for council papers, RMS submissions and board reports.

  • Verified Savings & Audit Trail

    Every prediction tied to an intervention, attached evidence and a verified outcome. Your auditor can trace every dollar from the forward works programme back to an individual inspection photo or sensor reading. Independently verified, not self-attested.
