Explain simultaneous use and existing provision
Provide the people present together, duration and break pattern. For Winter Garden work, list overlapping trades; for events, include helpers and vendors. State which permanent bathrooms remain available and whether separate activity areas need their own access.
Treat the recommendation as a complete proposal
Ask how toilet quantity, washing, accessible facilities and cleaning relate to the expected use. Do not apply one headcount formula to every situation. Review applicable requirements with the responsible organiser and confirm the equipment arrangement for the actual property.
Explain where demand is separated
A total count may conceal crews or guests in different working or activity areas. Describe those groups, their busiest overlapping periods and the permanent bathrooms each can use. Ask how the proposed quantity and placement work with washing and service; do not turn a rough estimate into a claim that every site requirement is met.
- Groups in different areas
- Peak overlap and available bathrooms
- Quantity considered with placement and support
