21. Johnson Controls Fire Protection, LP. has been involved with various fire life safety projects at

Selfridge Air National Guard - for over twenty (20) years. In our past performances, we have standardized all initiating and notification circuits to be installed class B wiring. The specification section 283176 states to install all fire alarm simplex products are to be installed with class A wiring.

Please clarify if the fire alarm devices shall be installed class A or B wiring.

a. Class A wiring is typically utilized for hangar projects, however, new language in UFC 3-600-01 makes it clear Class B is preferred. The drawings and specifications will be updated in addendum 1 to show Class B wiring.

22. Drawing F-103 does show 10 detectors, but that is for the triple coverage required for automatic release of a foam system per UFC 4-211-01. Sundown Policy Change 1 removed the foam and modified this coverage requirement to double coverage. Per spec, 28 31 76 § 3.3.6 Provide a sufficient number of optical flame detectors around the perimeter of the hangar bay, such that all portions of the hangar bay are within the range and cone-of-vision of at least two (2) detectors. Per spec 28 31 76 § 2.22 The detector manufacturer shall determine or approve the detector layout. Det-

Tronics has determined that 8 detectors meet the double coverage specified. Please clarify if 8 flame detectors are sufficient for this project and meet the requirements of the specification 283176 and drawings dated December 16th, 2022.

a. The 10 detector layout was provided by the manufacturer during design to meet the Sundown

Policy Change 1. If Detronics has provided an updated layout with 8 detectors it is acceptable.

However, the latest Sundown Document removes the requirement for flame detection therefore it is recommended that the base remove the system since it has a high cost and is no longer required.

23. Per the specification, section 283176, item 3.8.3 Intelligibility Tests with any CIS testing capabilities in relation to NFPA-72 intelligibility of an emergency communication system is considered acceptable.

Intelligibility measurements are not required in large open areas such as industrial work areas, warehouses, and aircraft servicing areas, garages, and similar facilities. Please clarify if

CIS testing procedure will still be part of this scope of work.

a. Yes, CIS testing is still required throughout the facility by UFC 4-211-01 Section 3-6.20.3 and project specifications.

24. As per the attachment current DOD standards call out for ASCE 7-16 for design standards for tank design but in this solicitation, it is calling out for ASCE 7-10 which is from the earlier versions. Please let us know which code needs to be used for Tank design as we need to provide the shop drawings which needs to be signed by a PE.

25. Specification 102113 lists the toilet partitions as both overhead braced and ceiling hung. Drawing A-

401 shows only overhead braced partitions. Please verify if they are ceiling hung or overhead braced.

(Architectural, Ref: A-401/102113).
