6) 1.6.10.10 of the design requirements calls out to provide new receptacles/ switch plates in all rooms. Will the receptacles and switches need to be replaced as well?

ANSWER:

Yes-the requirement includes the receptacles and switches as well.

7) During the Contractor’s site walk the Base Fire Dept and Anti-terrorism-Force Protection (ATFP) Representatives noted that there should be three (3) LOC’s provided throughout the Control Tower in lieu of the two (2) required in paragraph 1.6.10.11 of the Design Requirements.

ANSWER:

Section 01011-Design Requirements-Paragraph 1.6.10.11 is changed to require three (3) LOC’s throughout the Control Tower at no more than 200’ separation. The Final locations will be determined during the design process per the approval of the Base Fire Dept. and ATFP Officer.

8) During the Contractor’s site walk the Base Fire Dept noted that the Control Tower existing Fire Alarm and Mass Notification System (FA/MNS) strobes included two (2) separate colors-amber for MNS and clear for FA- and combined onto one devise. Will these devises have to be changed out to a single clear strobe per new pending UFC changes?

ANSWER:

NO-The existing FA/MNS devises (dual strobe) in the Control Tower will remain as is.

There is no change in the requirement to provide a single clear strobe. Any new strobes added as required for this project scope will match existing (dual strobe-amber for MNS and clear for FA).
