Answer No. 2: Please provide an overall schedule to include the days that you will need access to the rooms as a submittal prior to start of work Question No. 3: Is there a way to coordinate access to the 2 ER Rooms in the same day, shut down the ATS 3, which powers all or most of the hospitals MRI machines, and Panel EGR to tie it all in, in the same week and shut down ATS#3 and the panel feeding it, all in the same week?

Answer No. 3:

Part 1: both ER rooms would be able to be closed at the same time, in doing so a barrier would have to be placed at the entrances, as only one tile can be out at a time otherwise.

Part 2: ATS-3 is critical and down time is limited to four hours in total, it can not be down for a week.

Question No. 4: What are the hours we can work, without noise affecting patients with drilling through concrete walls?

Answer No. 6: No more than 4 hours. Provide schedule of work Question No. 7: Do we need to shut down the Panel EGP, which supplies ATS #3 and features a 225 amp breaker, in order to work on it, or can we work on it while it's live?

Answer No. 7: Panel EGP is only energized when the generator is running, there will be no problem in shutting the main breaker off, located left of the panel in generator control gear, as long as electrical staff is made aware at the time, no notice would be required for this portion of the project. Question No. 8. Please confirm award contractor will have access to the emergency room during construction.
