Counting units by crew size and phase
A crew of a given size needs a set number of toilets at each phase, and the count goes up when the crew does and comes down when the job moves to a lighter phase.
A small crew on a demolition or a first-fix stage can use a single unit, because the crew is spread over the site and only some of them are at the unit at any one time. A larger crew at finishing, when the whole crew is in one building, will queue for a single unit within an hour.
The plan sets the count from the number of people on the site at the busiest time and the number of hours they spend there. The contractor's own schedule is the source for both, and the plan records it.
Keeping the unit clear of the work zone
The unit goes at the edge of the work zone, off the delivery route and the fire access, and where a worker can reach it without crossing a live work area.
A unit inside a live work zone is a hazard to the worker walking to it and to the crew moving materials. The technician places the unit where the walk is short and the route does not cross a lift, a scaffold or a pile of material.
Deliveries are the other conflict. A truck that needs the loading bay cannot be blocked by a unit, so the spot is measured against the truck's turning and the bay's door.
- At the edge of the work zone
- Off the delivery route and loading bay
- Clear of the fire access and hydrants
- A short walk from the work area
Servicing and handwashing on a job
A job site needs a steady servicing visit and a handwash station beside the units, because a crew that works with materials and dust needs to wash before it eats.
Servicing on a job is usually set on a fixed weekday so the crew knows when to expect the truck. A visit on a Monday morning before the crew arrives is less disruptive than a visit at lunch.
A handwash station needs water and a place to drain, or a holding system that is emptied on a schedule. It is sized to the crew and placed beside the units so the washing and the toilet are in one place.
Moving and removing units as the job ends
Units move with the phase or come out at completion, and the spot is restored and signed off by the contractor so nothing is left behind on the street.
A unit moved from one phase to another is moved on a planned day, when the crew has agreed the new spot. A unit removed at completion is emptied and collected, and the spot is checked for spills and marks.
The contractor signs off the collection so the record shows the unit was taken away and the site was left in the state it was found.
What the superintendent needs to see
A site superintendent needs a simple record of the count, the phase, the servicing days and the contact for a fault, and the plan gives them on one sheet.
Most superintendents do not want a drawing of the restroom. They want to know how many units there are, when the next visit is due and who to call if a unit is low or broken. A single sheet with those four things, posted at the site office, answers most questions before they are asked.
The sheet changes when the phase changes, and the superintendent is sent the new version before the crew moves onto the new phase.
Weekends, holidays and the stopped site
A site that stops for a weekend or a holiday needs its units checked and locked, and the servicing schedule skips or shifts the visits so no unit goes unserviced through a long stop.
A site that closes on a Friday and reopens on a Monday leaves units standing for two days. A unit left with a full tank or a dirty seat is a problem for the crew on return, so the Friday visit is set for the last working hour.
Where a stop is longer than a weekend, such as a winter break, the units are either emptied and locked or collected, and the crew is told which option the plan has chosen before the stop begins.
