We don’t have any, but I have heard of these facilities. From my understanding they have become really popular over the past few years. I beleive many of our Cities will see these in the coming years.
I would agree with Duncan, the building department should be involved; as they have altered the original design of the building related to egress and exiting. In addition, I would not accept the reliance on an employee opening doors with a key.
From a code perspective, I believe if they contact the right consultant, they could develop an acceptable alternative solution with the installation of proper locking hardware connected to the fire alarm system, provision in the fire safety plan, etc.
