## Use cases

### Property Underwriting Hazard Scoring
A commercial property insurer scores addresses under consideration for new policies by checking whether the location or surrounding block has a history of utility strikes, particularly gas line hits, which signal elevated subsurface risk and potential for future claims.

| Street Address       | Facility Hit   | Facility Owner | Hit Date               | Hit Report Status |
|----------------------|----------------|-----------------|------------------------|--------------------|

### Contractor Liability Pattern Detection
A surety bond underwriter evaluating a construction firm checks whether the company appears repeatedly as the party responsible for utility hits across multiple dig tickets, which would indicate a pattern of negligent excavation practices before issuing a new bond.

| Hit By Name          | Related Dig Ticket # | Facility Hit  | Hit Date               | Street Address       |
|----------------------|----------------------|---------------|------------------------|----------------------|

### Utility Vendor Incident Exposure Monitoring
A financial analyst covering municipal utility operators tracks how frequently a specific utility company's infrastructure is being struck across the city, using incident volume and facility type to assess operational exposure and maintenance liability that may not appear in public filings.

| Facility Owner       | Facility Hit    | Hit Date               | Hit Report Status | Street Address       |
