High-rise site: what's the backup plan if the service elevator is reserved?
We're 14 weeks into a 20-story tower. The crew is 45 to 50 people daily. I have one standard portable toilet and one ADA-compliant portable toilet lifted to the 20th floor by crane. The service elevator is constantly reserved for materials, steel, and drywall. My rental company schedules pumping every Tuesday, but last week they couldn't get access. The driver waited 20 minutes and left. Now the unit is nearly full and the crew is complaining. I can't move it to the ground because the crane is on another task. What's the backup plan when the elevator is booked? Do I need to schedule a specific elevator time slot with the GC, or is there a way to get the driver up there without the service car?
