Track who is present when work overlaps
A project may have a small early crew and a busier period when trades work together. Give the rental contact that pattern along with existing bathroom access. Discuss toilet locations, handwashing and service around where workers are actually based, not just the project’s mailing address.
Keep sanitation clear of material handling
Choose a position with the site lead before storage, skips and deliveries fill the space. Review how people approach the units and how later service reaches them. If the job changes, request a revised arrangement rather than moving facilities into a convenient but unassessed corner.
From overlapping trades to ongoing service
Describe a typical busy workday: which trades overlap, where they work and which existing bathrooms they may use. Then identify the project stage most likely to change that pattern. This is more useful than selecting equipment solely from the number of people present during the initial site visit.
Include washing, supplies and the service arrangement in the same conversation as the cabins. Keep the unit position away from the space allocated to incoming materials and explain who can resolve a blocked approach. The rental plan should be reviewed as the worksite changes, not treated as a one-time delivery decision.
Use the busiest expected overlap of trades as a discussion point. The early groundworks crew may not describe the later workday; tell the rental contact when that change is expected.
