Presentation given to staff ahead of the McGuagh Hall Air Handler Replacement project.

1. McGaugh Hall Air Handler Replacement

5. Rusted Exhaust Fans

6. Leaking Coils

7. It’s just old!

11. Adapting to your input! In an effort to address the concerns raised by members of the Bio Sci community Facilities has met with EH&S, Goss Engineering, and Bio Sci Facilities to develop two plans to present today.

16. Work on AHU-1 AHU-3 in Operation Air Flow Exhaust Fan Max Flow Exhaust Fan Reduced Flow Each Floor of McGaugh Hall Work on AHU-3 AHU-1 in Operation Air Flow Exhaust Fan Max Flow Exhaust Fan Reduced Flow Each Floor of McGaugh Hall Phase 1 Phase 2 Plan B Plan B

18. Stocking up on provisions Do you use dry ice or liquid nitrogen? We encourage you to order extra for your department. We will work with the Bio Sci Facilities staff to cover the added expense.

19. Just in case! An empty -80 freezer will be set up in the loading dock area. Should a crisis arise it will be ready for you.

20. The Dry Run Plan A Wed. November 28th 8am – 12pm Shut off both air handlers and most building exhaust and monitor the temperature rise across the building noting potential trouble and reinstating air flow if a danger level is reached. Plan B Wed. November 28th 8am – 12pm Shutdown air handler 1 and lower the exhaust flow as shown in the phasing diagram. monitor the temperature rise across the building noting potential trouble and reinstating air flow if a danger level is reached. 12pm-4pm Shutdown air handler 3 and lower the exhaust flow as shown in the phasing diagram. monitor the temperature rise across the building noting potential trouble and reinstating air flow if a danger level is reached.
