How many restroom units does a roadwork crew need?
The count depends on the headcount on site and how far a worker can walk to a unit. It is checked against the federal table, not against a rule of thumb.
OSHA's construction sanitation standard, 29 CFR 1926.51(c), sets the toilet count by the number of workers, in a table that steps up as the crew grows. A small crew may need only one unit, and a larger crew needs seats and urinals counted by headcount.
Units that are in an unsanitary condition do not count toward the minimum, so a unit that is full, tipped or locked will not satisfy the count on its own. Washing facilities are a separate requirement under the same standard, and a crew with only a toilet on site has not met the full standard. Ask the foreman for the actual headcount for each shift, because a count taken on paper on Monday may not match the crew on Thursday.
Where should a roadwork unit sit?
Off the travel lane and outside the path of the barriers, on firm and level ground that a truck can reach.
The unit has to be far enough from live traffic that a vehicle drifting into a lane cannot reach it, and close enough that a worker does not have to cross the active zone to use it. Those two goals pull in different directions on a narrow street. A technician looks at the lane closures, the barriers and the crew's route before choosing a spot, and the spot is usually at the edge of the work zone rather than in the middle of it.
How do you move a restroom when the work zone moves?
A relocation is planned as a new placement. The route and the ground are checked again, and the old unit is removed on the same visit.
Work zones move. A paving crew works a block at a time, and the restroom has to follow it or sit too far from the people who need it. A move is a new placement: the technician checks the new spot, the route and the ground, then removes the old unit. Doing the removal and the placement on the same visit keeps the crew from losing its restroom in between.
Ask the crew lead to tell the provider when the barriers move, not only when the work moves. A lane closure that shifts overnight can leave a unit stranded behind a new barrier. A technician may need to re-site the unit to keep it reachable, and the crew should not have to walk through the work to reach it.
How often do roadwork units get serviced?
On a schedule set by the headcount and the length of the job, with extra visits when the crew is heavy on the unit or the weather turns.
A crew's use of a unit is steady and often heavy at the start of a shift and at lunch. The interval depends on how many workers share the unit and how long it stays in one spot. A busy crew on a long job may need a visit more often than a single person on a short one, and a technician sets the schedule at placement and adjusts it once the use is clear.
What moves the price up or down on a roadwork job?
The number of units, the length of the job, how often the unit moves and the access along the route. The price is explained and approved before work starts.
A job that moves the unit several times costs more than one that leaves it in place, because each move is a placement, a removal and a route check. A longer term adds service visits. More units on a wider job add placement and service time. Tight streets, closed lanes and steep grades add time for the truck, and a crew that needs a unit on a short notice schedule adds coordination time as well.
Weather and the time of year also matter. A unit on a winter job needs the antifreeze and the clearing covered as described on the winter units page, and a job that runs across seasons has to plan for both. The local provider quotes the job once the crew's count, the work schedule and the route are known, and explains the price before work starts, so the crew knows what it is paying for.
