Required Data
Building Geometry
Length, width, height, roof levels, projections, tanks, antennas and nearby structures.
Location
Coordinates, terrain, isolation, elevation and authoritative lightning-density data.
Occupancy & Use
Population, evacuation, public access, critical operations and service continuity.
Construction & Contents
Fire load, explosive material, structural materials, sensitive electronics and asset value.
Incoming Services
Power, telecom, data, pipelines, CCTV, signalling and external instrumentation.
Consequences
Life safety, fire, environmental damage, downtime, data loss and economic impact.
Preliminary Collection Area
For a simple isolated rectangular structure, a common preliminary geometric expression is:
This is not a complete risk assessment. Location, line collection areas, probability factors and consequence factors must also be evaluated.
Deliverables
- Risk-input schedule

Inspection, Maintenance and AMC
Visual Inspection
Check terminals, masts, conductors, joints, labels, supports, corrosion and mechanical damage.
Electrical Testing
Verify continuity, bonding, earth-system performance and SPD status using appropriate test methods.
Post-Strike Review
Inspect after a recorded event, severe storm, roof alteration or electrical modification.
AMC Documentation
Maintain inspection reports, earth-test records, event-counter readings, photographs and corrective-action BOQ.
