How many toilets does a large industrial crew need?
The count follows the peak shift, because a crew that peaks on one shift needs units for that shift. Under OSHA's table, the count rises with seats and urinals as headcount rises.
Large crews come in shifts, and the peak is often a single shift or a single trade working at the same time. A concrete pour or a steel erection can bring a large group onto the site for a day, and the count should be set for that day. The superintendent gives the technician the expected headcount by shift, and the technician sets the units against the highest of those numbers, not the average.
How is the yard laid out for units?
Units sit near the work zones, on firm ground and out of the path of freight, with one cluster for each area where a crew works.
A yard is divided by work, not by building. The frame crew, the concrete crew and the finish crew each work a different zone, and each zone gets a cluster close enough for a short walk. The technician marks those clusters on the site plan, so the superintendent can see where each group will be and can ask for a unit to move when the zone changes.
How does service work around freight traffic?
The service truck uses a set window and a lane that is not on the freight route, agreed with the yard. The times are set so the truck is not caught between pours or deliveries.
Yard traffic is the constraint on every visit. A pumping truck is large, slow to turn and heavy on the ground, and a lane used by concrete trucks or forklifts can be unsafe for it at the wrong time. The technician agrees a service window and a route with the superintendent, and the truck uses that route on each visit so the crew and the drivers know where it will be.
How long do units stay on an industrial build?
A warehouse build can run for months, so a unit placed for the start of the job may need a different spot and a different count by the time the interior crews arrive.
Phases change the count. Foundations, structure, roofing and interior finish each bring different crews and different headcounts, and the count should follow them. The technician reviews the count at each phase change, adds units for the new crews and removes the ones the finished areas no longer need.
What changes the price?
The count, the number of clusters, the number of visits, the access to the yard and the length of the build all change the quote. The price is explained and approved before work starts.
The number of units and clusters is the first factor. A yard with many work zones needs a cluster for each zone, and each cluster is its own placement and its own stop on the route. The number of visits and the length of the build come next, since a build that runs for a year means many more visits than one that runs for a few weeks.
