15. Can you clarify if it is the intent of the project is to keep all existing working components in place to allow the current operation to continue while the new system is installed?

A: That is the intent. The major concern for taking the old system down during construction is the audible bell schedule. We are open to alternatives to facilitate the project.

17. Is it in the governments best interest to have an emergency call button and an integrated camera to ensure emergency events can be assessed visually and if so would recording of the event be in its best interests?

18. The government has stated an intent for “mass notification”. Per UFC 3-600-01 a Fire Protection Engineer is often required to perform an analysis and design review and UFC 4-021-01 dictates the design and O&M standards for all branches of service directing NAVFAC and AFCESA as two of the responsible parties for determination of interpretation and improvements. Has a determination been made that meeting UFC requirements for UFC 3-600- 01 and UFC 4-021-01 for this solicitation are or are not required?

A: Due to the security requirements of the building, meeting UFC 3-600-01 and UFC 4-021-01 are not required in regards to tying the proposed PA system into the current Fire/Mass Notification system.

19. Per UFC 4-021-01 any PA system in place must have the ability to interrupt PA system announcements and to silence building background music while delivering voice messages. Will this supporting capability need to be available on the new PA system should the building receive a future mass notification system?

20. UFC requires conduit for mass notification systems. Will the system require new conduits or is securely mounting low voltage cabling in accordance with UFC 3-580-01 Information and Communications Technology Infrastructure Planning and Design acceptable?

A: Secure mounting IAW UFC 3-580-01 is acceptable.

21. As for time sync across the school will GPS time be required or will the school develop and SOP for updating network time manually?

A: With contractor assistance, the school will develop an SOP for manual time updates.

22. What vendor is currently supporting or recently supported the Dukane PA system repairs for the school?

A: There is currently no support for the installed system.

23. Can you provide photos of each electrical room where power will be available, mark the location of the room on the plans, and a provide a photo of the electrical panel with adequate space for a 20 amp breaker to be used to power each rack for the new system on each floor?

A: See Pictures in folder labeled “Electrical Closet”

24. Can you clarify if space D106 will require call button, emergency button, clocks, or speakers?

A: D106 will require a connected clock placed at the rear of the space. No other equipment is required in that space.

25. Can you clarify if outdoor speakers will be required on the building to replace existing speakers?

26. Can you clarify 2 hour rated fire wall locations on the plans?

A: See Building Schematics. 2 Hour rated fire walls are noted on the schematics.

27. Can you clarify 1 hour rated fire wall locations on the plans?

A: See Building Schematics. 1 Hour rated fire walls are noted on the schematics.

28. Can you clarify if there is any concrete/masonry interior walls or if they are all sheetrock?

A: Construction is noted on the schematics.

29. Can you clarify the separation requirement for unclassified air gapped network cabling from the PA systems and the classified and unclassified government network cabling?

A: Separation between PA/unclassified cabling and classified network cabling is 6in. Separation between classified and unclassified/PA equipment is a minimum of 3ft.

30. What is the final decision on decommissioning on old system, will it include the decommissioning of old wiring as well as the rack in the auditorium?

A: Old rack and equipment shall be decommissioned. Old wiring can be retired in place as necessary.

31. Is there current cable tray or ladder tray in the hallways?

32. Is there any requirement for tying into the existing fire alarm? (the consensus during the walkthrough was no, but weren’t 100% sure) A: No. Since PA system is a stand alone, it shall not interface with any system that has outside connections such as the fire alarm.

33. Can we use existing space and power from current IDF Cabinets?

34. Can we use GPS based NNTP services which requires an antenna mounted outside the building?

35. Is there any requirement about how large the Time display is?

37. Is there set requirement of uptime duration on UPS backup power? (i.e. 90 minute, 2 hours, etc.)

A: 60min for the server rack.

38. We were told that work hours could be 10:30 PM to 5AM for this project, however we were also told that the last classes end 6 PM and that there was some room for adjustment of working hours (like 7PM -2:30 AM). Can we get a definitive answer on this?

A: Classes end by 5PM. Study hours for the students are from the end of their classes until 10:30PM. We may be able to facilitate specific work during the designated study hours timeframe, but that will require coordination beforehand as to not disrupt the academic training that occurs in the building. These working hours are to specifically address any work that will take place inside the classrooms. Work that will take place in the hallways, electrical closets, attic, and other spaces can be accomplished during the day. Work done during the academic day must be as unintrusive as possible as to not interfere with the academic training.

39. Emergency functionality: Support rapid dissemination of emergency notifications, alarms, and lockdown procedures across all exterior areas - (is this doing with access? are they going to run this through access to go to the pa system to make the audio pick up when button is hit?)

A: The PA system has no connection to access control. Audio pickup is activated by the announcing station after a distress signal is received.

40. Stand alone network operation: The system shall operate on a stand alone network, with all necessary software updates provided by the Contractor as required. The Contractor shall provide all equipment, hardware, and resources necessary to support the operation and maintenance of the Software (if this is stand alone how do they expect to integrate to all other systems?)

A: There are no systems to integrate outside of the bounds of the PA system.

41. Approximately how much cable do we need to run? Are there any existing cables we need to use?

A: KTR shall use the drawings to perform material take-offs for this requirement. Existing conduit and cabling may be reused if they are compatible with the new system and are code compliant.

42. SOW mentioned that we need to Utilize the existing PA software to manage announcements, schedules, and message boards for exterior zones. (What is the brand of the existing PA system or what is the current software?)

A: This was for the UNFONDED CLIN that is no longer required.

43. What is the ceiling height from where we need to run the cables?

A: 9ft

44. Are there existing conduits that we need to use? or we need to provide the conduits?

A: KTR shall use the drawings to perform material take-offs for this requirement. Existing conduit and cabling may be reused if they are compatible with the new system and are code compliant.

45. Is this a one time purchase or do you require a system that supports monthly subscription based cloud services?

A: One time purchase

46. Can you better describe the intercom requirements for exterior?

47. Please clarify the requirement “Integrated scheduling and messaging: Speakers must include a built-in clock, message board, and bell schedule.” You want the actual speaker to have a clock and message board?
