50-person film crew, 12-hour days: how many porta potties?
We're running a three-week film shoot with a 50-person crew on a rural location. The days are long, 12 hours on set, with lunch catered on site. Breaks are short and staggered, so the restroom situation has to be efficient to avoid production delays. The ground is level grass, and a vacuum truck can park right next to the placement area.
I'm debating between a few standard units and a restroom trailer. The crew will appreciate any comfort we can provide, but the priority is zero downtime. We'll need at least one ADA-compliant unit to meet the ADA 5 percent cluster rule. For a crew this size working these hours, how many total units should I plan for? Is a restroom trailer overkill, or is it worth the investment for crew morale over three weeks?
