Ventilation, SCADA, life safety, traffic systems
Commissioning software for tunnels and highways where the road authority will not accept an assumption.
Tunnels and major highway schemes carry life-safety consequence in their ventilation, fire and SCADA systems, and a road or transport authority that inspects every claim before it signs. Deskely holds ventilation, fire life safety, SCADA, traffic management and lighting as linked subsystems, so integrated systems testing is run and evidenced against a fixed acceptance framework.

The problem
Dozens of subsystems have to behave as one system, on command, under fire scenarios.
A tunnel brings together jet fans, dampers, CCTV, variable message signs, fire detection, SCADA, emergency communications and traffic management, each installed and tested by a different specialist.
The road or transport authority does not accept individual test certificates in isolation; it requires proof that the systems respond correctly together, scenario by scenario, before it will accept the asset.
Deskely models each subsystem and its cause and effect relationships explicitly, so integrated systems testing evidence is structured the way the authority actually reviews it.
Setting up the register
Ventilation, fire, SCADA and traffic are linked subsystems, not separate projects.
Jet fans, dampers, extraction points, detection zones, SCADA points, CCTV, VMS, emergency telephones and traffic management assets are tagged by chainage or section and grouped into their systems.
Cause and effect matrices are held as structured data against the devices they connect, so a fire scenario's expected fan and damper response is a query rather than a document cross-reference.
Drawings, SCADA point lists and cause and effect schedules are parsed into that structure, keeping the register aligned with the design intent documents the authority will audit against.
Execution
Pre-functional checks feed integrated testing, scenario by scenario.
Each device is proven individually first — jet fan rotation and vibration, damper stroke, detector response, SCADA point-to-point verification — before it is included in an integrated test.
Integrated systems testing is then run scenario by scenario, with the actual system response recorded against the expected cause and effect outcome for each one.
Traffic management systems, lighting and CCTV coverage are verified against the same chainage structure, so a section's readiness reflects every system that operates in it.
Authority acceptance
Acceptance is a dossier built from evidence, not a claim made at a meeting.
The authority acceptance package is assembled from the same device and scenario records used during testing, with every signature carrying a name, role and timestamp.
Any deviation between expected and actual scenario response is logged as a punch item with a category and an owner, so it is visible before the authority finds it during their own witness testing.
The maintaining authority receives an asset register with full test history, settings and cause and effect logic intact, which is what supports safety case reviews long after opening.
How it runs
From individual devices to an authority-accepted asset.
Tunnel and highway schemes are dominated by proving systems together, which is exactly where structured cause and effect data earns its keep.
- 01
Model by chainage and system
Ventilation, fire, SCADA, CCTV, VMS and traffic assets tagged by section and grouped into their systems.
- 02
Hold cause and effect as data
Expected system responses to each scenario recorded against the devices involved, not just described in a document.
- 03
Run device tests, then scenarios
Individual device pre-functional checks completed first, then integrated systems testing recorded scenario by scenario.
- 04
Assemble the acceptance dossier
Authority acceptance package built directly from signed device and scenario records, with deviations tracked as punch.
