Why it matters
Without AI, undetected decay, incorrect compartment delineation, unsafe hot work practices, hidden roof void risks, and unclear evacuation status can lead to failures in protection of significance and safety, with fragmented records and delayed actions.
From design to safety
Design
AI-supported conservation planning
The AI reads the conservation management plan, quinquennial inspection findings, significance assessments, and service layouts to flag high-risk locations and propose minimal intervention fixes.
- Aspirating smoke detection panel
- Fire compartment wall section
- Roof access hatch
- Evacuation route signage
Build
During build: monitored constraints
The AI integrates with construct stage Drawings, method statements for hot works, and works permits, checking alignment with fire compartments, roof void access, and temporary egress provisions.
- Aspirating smoke detection panel
- Fire compartment wall section
- Roof access hatch
- Intumescent seal on fire doors
Operation
Live monitoring of risk thresholds
AI correlates feed from aspirating detectors, climate sensors in roof voids, and evacuation status to detect anomalies and trigger alarms while logging state of conservation.
- Air-Sampling Tube Network
- Aspirating smoke detector unit
- Intumescent door seals
- Emergency lighting controller
Maintenance
Ongoing condition surveillance
The system analyzes quinquennial inspection defects, sensor drift, and service reports to schedule calibrations, replacements, and reinforcements, ensuring continued protection of significance.

- Aspirating pump and blower
- Roof void access hatch
- Fire-rated door assembly
Safety
Safeguards for occupants and assets
In fire or flood events, AI prioritises evacuation, integrates with fire brigade guidance, and preserves state of conservation data, causing actions to be signed off by the qualified person.

- AI action
- Alerts maintenance and reallocates air flow to maintain monitoring integrity
- 3
Fire compartment wall section
- Watch for
- Cracking through plaster or masonry compromising fire resistance
- AI action
- Flags compromised barrier and schedules reinforcement work
- 4
Intumescent seal on fire doors
- Watch for
- Seal degrades or gaps behind doors during movement
- AI action
- Alerts occupiers and requests inspection or replacement
- 5
Roof access hatch
- Watch for
- Unsecured hatch or corrosion of hinge, allowing unmonitored roof void access
- AI action
- Triggers inspection and secures access controls
- 6
Evacuation route signage
- Watch for
- Misleading or obscured signs hindering safe egress
- AI action
- Updates dynamic guidance and confirms visibility during drills
Worked example
Catching a seal leak before a charter
Illustrative scenario with sample data.
A heritage foundation with five sites, aged 200+ years and 120k annual visitors, relies on critical fire safety systems in historic interiors and roof spaces.
Signal in
sensorReadings: {smokeRate: 0.8, airflow: 0.95, doorSeal: 0.72, hatchState: closed}, quinquennial: {inspectionDate: 2026-03-12, defectsLogged: 3}, CMS: {stateOfConservation: 'good'}
System out
alert: potential seal leak detected in fire door 2B; workOrder: schedule reseal and re-test; signOff: conservation architect required.
Human sign-off: Conservation architect reviews the work order, approves reseal strategy, and signs the fire safety update to the quinquennial report.
How to roll it out
Phase 1
Weeks 1 to 4
Baseline data collection from all detector lines, air-flow validation, and existing compartment mapping.
Phase 2
Weeks 5 to 8
Integrate hot works controls, roof void monitoring flags, and evacuation status into the management platform.
Phase 3
Weeks 9 to 12
Drill and calibrate alerts, finetune thresholds, document decisions in the conservation management plan.
Where people stay in charge
- Decisions on fire safety measures must stay with a qualified person, and only they may approve evacuation changes that affect occupancy.
- No action may be taken without validated readings from certified detectors and a signed off plan by the fire safety officer.
- All data handling must maintain the integrity of significance records and be auditable for governance and compliance.
Questions owners and crews ask
What is aspirating smoke detection and why use it in heritage buildings?
Aspirating smoke detection draws air through a network of tubes to detect early smoke particles, enabling earlier intervention in sensitive interiors where visual cues are limited and preservation is crucial.
How are fire compartments mapped in historic structures?
Fire compartments are defined by fire-resistive barriers, occupied space boundaries, and heritage significance considerations, then documented in a conservation management plan with quinquennial inspection inputs.
What happens if hot works are required near priceless materials?
Hot works must follow a controlled permit process, with isolation of combustibles, continuous monitoring, and a sign-off by the fire safety officer before work begins.
How does evacuation integration work with heritage sites?
Evacuation signaling is integrated with route signage and emergency lighting, ensuring clear egress guidance is maintained during events and drills, aligned with safety management standards.
