Set expectations in writing [1]:
- Explain the sources: surface evidence observed, 811 markings, utility records and maps, and any subsurface utility engineering (SUE) if contracted.
- Define the scope in the proposal: what will and won't be shown, and how.
- Label sources on the drawing: observed, marked or from records.
- Note limitations clearly: underground utility locations from records or markings aren't guaranteed.
- Offer SUE services (designating or locating) through your firm or a partner, when the client needs higher quality data.
Coordinate the request early with the lender, title company and client. Utility information often takes the longest to gather [2].
