School Bathroom Nightmare, Part III

Twenty days into Ramadan (a full month after the estimated completion date), and the bathrooms still aren't finished. The foreman only shows up to work every few days, and then got most of the measurements wrong ("if you didn't want me to add anything onto the plan you drew, you should have told me not to add anything."), meaning we had to buy more bricks, cement and steel. Then he forgot to leave a space for the windows. I've passed the point of frustration and now everything that goes wrong just makes me laugh. Though I do want to somehow (without creating any enemies) make sure that the association realizes that if we'd gone with the original foreman, the bathrooms would have been completed a month ago, to the exact measurements we wanted, under budget, with windows. School starts in six days, and there's still a classroom full of cement, random wood pieces and a duct tape, to-scale drawing of the plan on the floor.
