23. Please define the spare equipment required for each fire protection systems.

a. For the clean agent system itself, there would not be any spare parts (we aren't asking for extra nozzles, extra cylinders etc.) but for the releasing system itself, we would require 10% of initiating devices (smoke detectors etc. including bases), 10% of notification devices (discharge beacons, strobes, horn strobes etc.), a spare bypass switch (the key switch they turn when they are testing to avoid discharge during routine maintenance) and a spare abort switch.

a. There is an existing wet pipe system protecting rooms 309 and 205.

31. Scope of Work on drawing FP-001 States “Existing wet sprinkler system will remain as the primary fire suppression system for the entire building …” What work is to be done to the fire sprinkler system?

a. See SOW.

32. Stated in spec section 212200 1.02 Part 3A “All work relating to the design and installation of the wet pipe sprinkler and/or pre-action sprinkler system.” What work is to be done to the fire sprinkler system?

33. Stated in spec section 212200 1.02 Part 4D “… dedicated 20-amp breaker to each fire system control panel and the pre-action air compressor...” What work is to be done to the fire sprinkler system?

a. There are no HVAC drawings available.

39. General Notes on drawing FP-001 #16 states “provide manually activated exhaust system to facilitate the extraction of any remaining clean agent after the hold time of total flooding discharge...” Is it the intent to have a purge exhaust fan system installed?

42. Can the locations of the dampers needed to install be noted on drawings?

a. The provided drawings are concept only and not complete. The contractor shall verify and complete this as a part of the design build process.

43. Stated in spec section 212200 section 1.06 “Main/ Reserve Switch.” Is it the intent to have a main/reserve clean agent system installed?

a. No.

44. Stated in spec section 212200 section 2.01 “Manufacturers” Kidde Fire Systems is proven to be an equal manufacturer. Kidde Fire Systems is a global leader in fire protection, protecting people, property, and processes from fire hazards. Is Kidde Fire Systems an acceptable substitution?

a. As long as the product is "non-proprietary" and the government is provided with all programming tools available it would be acceptable. By all tools we mean any programmers, computer software, key codes etc. If the government will incur cost to continually attend training for programming rights, then it wouldn't be an acceptable alternate. Keep in mind that the releasing panel needs to be separate from the building fire alarm system and it must report all alarm, supervisory and trouble signals to the building fire alarm system for transmission to our central station.

45. Stated in spec section 212200 section 2.06 Fire Extinguishing Clean Agent part A “Clean agent HFC-227ea, or equal ” Allowing only one type of gas as the fire suppression agent the solicitation does not comply with Air Force Engineering Technical Letter 01-18, " Fire Protection Engineering Criteria - Electronic Equipment Installations", Section 7.3.11.

Therefore, responses to the solicitation proposing other authorized fire suppression gases should be permitted. Is Novec 1230 an acceptable substitution?

a. It states “or equal” which allows for more than one type of gas to be considered. It is the contractor’s responsibility to ensure that the "clean agent gas" and installation are in compliance with ETL 01-18 and NFPA 2001. The government will only reject a specific gas if it isn't in compliance with these 2 documents. The intent of 7.3.11 and

7.6 is to eliminate Halogenated, agents, Hydrofluorocarbon and Perfluorocarbon agents and only use agents that have no known adverse environmental impacts.

46. Is there a staging area provided to the contractor?

a. Yes, the contractor will be able to select a staging area. There is space available both inside the fence line of 7011 and outside the fence line, however, the approval of the staging area will be accomplished during the AF Form 103 work clearance process to be completed after award.

47. Is the work to be done between normal working hours?

a. Yes, all work shall be done during normal working hours.

48. Are bathrooms facilities provided?

a. Yes, the contractor can utilize the restrooms inside of building 7011.

Officer or can the CQC Manager also function as the Site Safety Health Officer?

a. The SSHO can be either the Superintendent or the QC Manager, however, the

Superintendent cannot be the QC Manager.
