How many toilets are needed for large builds?
This one says 20 for a construction site with 200 workers: https://tardishire.co.uk/toilet-hire/tardis-toilet-calculator/ - but only 3 for a 200 person concert (10 hours per day). If conert is multiplied by 2.4 for whole day - that makes 7 toilets. That is 3x off the construction site value. Do construction workers use 3x more energy?
