Built around the regulation:

OSHA Worker Ratios for Unit Quantity Planning

OSHA 1926.51(c) mandates one portable toilet for every twenty workers on a standard forty-hour shift. Longer hours or the absence of a hand washing station require additional units to maintain compliance. Crew size and shift duration dictate the final count for your job site. Review these four categories to determine your requirements.

1 per 20 Workers

One toilet per twenty workers is the required baseline for single shift crews.

Female-Worker Add

Separate stalls once crews include workers of more than one gender.

Urinal Substitution

One urinal counts as one fixture, but not more than one-third of the total requirement.

Large-Crew Step

Crews of 200 or more workers use one fixture per 40 workers per shift.

Weekly Servicing Schedules on Active Job Sites

Construction sites in Charleston with crews under twenty receive a weekly pump and pressure rinse. Once headcount exceeds thirty or summer heat persists, our crew switches to twice-weekly service. Our driver swaps the deodorizer puck, restocks paper, and logs each visit in our digital system. These records ensure site supervisors maintain a proper paper trail for all compliance audits. Reach our dispatch for scheduling at (843) 350-2992.

Rough-Site Logistics with Crane-Liftable Units

High-rise builds in Charleston need jobsite units that move with the work — our crane-liftable restrooms have a reinforced steel cage and rigging eyes for tower crane lifts between floors. The skid-mounted base rides a crane sling to the hoist deck; rugged casters roll it into place. On grade, anchor to gravel or bolt to concrete. Each unit cycles waste through a holding tank drained by suction hose into the vacuum truck’s waste tank. Relocate between phases with monthly construction portable toilet rental pricing that meets the OSHA 1910.141 sanitation rule for construction worker restrooms.

Construction Site Questions

  • + How many units do I need for a thirty-worker crew?

    Two standard units satisfy the waste tank capacity for thirty workers under OSHA 1926.51(c), while adding an ADA stall supports mixed-gender crews or public-funded projects.

  • + Can the service day be locked to a specific weekday?

    Monthly contracts lock in a fixed weekday and route window for the duration of the entire construction build.

  • + What does monthly billing include?

    Delivery, weekly servicing, paper and sanitizer restocks, final pickup and phase relocations on long-term contracts.

  • + Do you deliver to active concrete pours?

    Concrete pours need the drop scheduled ahead, units staged clear of the forms on gravel, and repositioned once the pad cures.
