Sounds like the start of a plan. My questions would be around those 10 minutes at the entry door. What do we do with people? How are they connected to the test? How do we keep separation between people? How do we grant access after the passed test? What happens to those around if someone is +ve?
Maybe it can be accompanied with an app which would send you test result so you don't have to literally queue. And then use the result to enter the building.
