9. The location of door DA-104A falls in the middle of the existing wall mural. What is the expectation for painting the wall around the new door?

Drawing A-4 notes "Paint to match adjacent walls" at location of existing door filled in with CMU block. Any disturbance caused by demo for new doorways DA-104A and DE-100A should be touched up with matching solid gray paint.

10. There is an IBR repeater or LAN hub mounted on the hanger wall in the new aisle way created by moving the fence. Will this stay or will it need to be moved?

Did not see anything like that in the new aisle, although there is a PA amplifier mounted to the wall near the mural. If there is anything in the way of the two doorways being opened up, such as the amp, conduits, water lines, etc. they will need to be relocated. The new aisle created by the fence will be wide enough that anything mounted anywhere else on the wall can stay (except maybe the TV).
