Clarify what can be handled remotely
Send current property information and ask WTG what further review is needed. Photographs may support the initial conversation without replacing every on-site observation. Identify a representative who can explain the grounds and provide approved access if a visit is arranged.
Agree on the completion handoff
Ask how the approved work and any changes will be documented for you. Keep the map, exclusions and follow-up questions together. An unattended visit should still have a clear authorization and record. If necessary information or access cannot be confirmed, resolve that before proceeding rather than relying on a vague instruction to do whatever is needed.
