Separate the order contact from the site contact
The person approving a purchase order may not be the person meeting a vehicle. Provide the appropriate contacts through the rental team and explain who can approve changes. Record the agreed delivery location in the site plan so that different subcontractors do not give conflicting directions.
Review each change in the project footprint
Early earthwork may leave an open entrance; later fencing, paving or occupied areas can change access. Look ahead to those stages when choosing a restroom location. If relocation becomes necessary, ask the supplier how it should be handled rather than dragging or lifting a cabin yourself.
Multiple work zones can call for separate accessible locations instead of one distant group of units. Discuss walking routes and service access for each location, including whether the vehicle can reach them without crossing active work.
Document the ongoing arrangement
Ask which cleaning and supply visits are included and how changes in use should be reported. Keep a simple site log of access problems or missed visits with dates and unit location. Send the facts to the rental team so it can investigate; avoid assuming every issue has the same remedy.
Close the rental as deliberately as you opened it
When the project changes to an occupied building, confirm which permanent toilets are available before removing temporary facilities. Request pickup, leave the equipment accessible and reconcile the final invoice against the agreed rental and any approved changes. Billing periods and cancellation terms must come from your actual proposal.
