How many units does a downtown site need under the federal rule?
The count follows the crew, using the federal table in 29 CFR 1926.51(c)(1). A small crew needs one facility, and larger crews need seats and urinals set by the table's ratios.
The table sets one facility for 20 or fewer workers. Above 20 workers it calls for one toilet seat and one urinal per 40 workers, and at 200 or more it calls for one toilet seat and one urinal per 50 workers. A widely repeated figure of one toilet per 20 workers does not match the table, and a plan built on that figure will fall short on a larger crew.
How far can a unit sit from the work?
Far enough to be used, but not so far that the crew walks away from the work to reach it. OSHA treats a toilet that takes too long to reach as not provided, so the distance is measured in practice, not on a plan alone.
OSHA's standard interpretation letters say that a toilet which takes too long to reach is not provided, and the sense of the rule is that the crew must be able to use the facility within the working day without leaving the work for long. On a downtown lot, that usually means the unit sits inside the fence line near the work area, or as close to it as the right of way allows.
Do construction-only units have to be accessible?
An informal 1993 Justice Department letter says that portable toilets used exclusively by construction personnel are not required to be accessible. The letter is not binding, so the plan should note what applies to the site.
The letter is informal guidance rather than a rule, and it does not bind a site or a court. The sensible course is to plan an accessible unit where the site is open to other people, such as the public using a nearby walkway or a visitor to the building, and to check the requirement for the particular site before the units are placed.
What does a right-of-way placement involve?
A unit on the right of way needs a Temporary Use of Right of Way permit, notice to 311 at least three days ahead, and a walkway that stays open. Sidewalks should not be closed for more than 14 days without approval.
A Temporary Use of Right of Way permit is needed to close a sidewalk or driveway for work on private property. The approved permit and the traffic-control plan stay on site, and the crew has to show them to the inspector if asked. The permit describes the closure, its dates and the route that pedestrians are sent along.
What moves the price of a downtown site plan?
The price moves with the size of the crew, the number of units, the placement, the servicing visits and any right-of-way work. The provider confirms the figure for the site before work starts.
Crew size and unit count are the first factors. A larger crew needs more seats and urinals under the federal table, and each unit has to be delivered, placed and serviced. A site with several staging points for a tall build needs more units than a single lot, and the plan should show the count for each stage.
