Plan around the hours without building access
Write down when setup begins, when participants arrive and when the last worker leaves. If an existing bathroom is closed during any of those periods, explain that gap to the supplier. Consider the route users will take after dark or in wet weather. Ask about handwashing replenishment and accessible facilities as part of the working layout, rather than adding them after a position has been chosen.
Keep servicing possible as the site changes
At a home project, delivery access can disappear when building materials or subcontractor vehicles arrive. Choose a position that remains reachable for cleaning, then tell the crew which approach must stay clear. At a public recreation site, get the manager's agreement on vehicle access and placement. Recheck the arrangement if the activity moves to a different part of the grounds.
Coventry temporary-facility planning terms
Compare the unit mix and service frequency against the hours when permanent toilets are unavailable. Include delivery, pickup, handwashing and any extended work period; ask how changes in crew size or event duration affect the proposal.
