W911YP‐18‐B‐2300; Repair Fire Suppression

Question: Does the entire system need to be brought up to current code, or just the new equipment installed?

Question: Just to clarify that the project will not be brought to a full ETL requirement

Answer: No, the entire system does not need to be brought up to code. The project scope is designed to eliminate the common inadvertent discharge causes without making a large investment in upgrading the system. The new equipment and modifications made in this project should meet code as much as reasonably possible given the scope of the project, but there is no intention to expand the scope of the project to modify the entire system. If a specified item will not work without upgrading further components of the system, that should be disclosed as soon as it is identified for the Government to make a determination.

Question: RFP Section 5.4 requires compliance with, "applicable UFC's, ETL's, local, state and national

Codes, base standards and all other applicable laws, codes and guidance." The scope of work in the RFP is very specific about the design of the detection and control system. If the requirements stated in the scope of work do NOT match applicable UFC, ETL, etc. requirements, then which takes precedence.

Answer: Any discrepancies between applicable code and the SOW shall be brought to the CO’s attention for determination. In general, the most stringent requirement will apply. As stated above, this project is not a full upgrade and only the work done in the project is intended to meet current code.

Question: SOW asked that all the trim on the Deluge valves be changed to Brass. Is it the intent to do the check valves trim above the deluge valves? And how far do we replace on trim that goes to the air compressors and drains on the deluge valves that drain to the exterior (Main Drains etc..)

Question: How far back on the air line should the deluge valve trim be replaced? Should the check valve trim also be replaced?

Answer: The air compressor trim shall be replaced with brass all the way to the air compressor. The drain lines shall be replaced with brass up to the point of the tamper sealed drain valve. The check valve trim shall be replaced as well.

Question: Are the Control Valves at base of the Deluge valves that have tamper switches needing to be replaced? (Most butterfly valves don’t have a field replaceable tamper switch and require the entire valves to be replaced)

Answer: No, project scope does not specifically require replacing control valves or tamper switches.

They would only need to be replaced if their replacement is necessary to meet other requirements laid out in the SOW.

Question: SOW states for pipe labels to be plastic wrap around type but not adhesive or strapped on. Do you want them to be magnetic type label (Vinyl adhesive signs are most common and most economical if considered)

Answer: Base prefers snap‐around labels. Magnetic labels are acceptable if they fully wrap around the pipe.

Question: Will a full trip test of the foam systems be required on this project?

Answer: Per SOW 2.2, Contractor shall develop a testing procedure with their QFPE that meets all the testing requirements specified in the SOW, NFPA 72, UFC 3‐601‐02, and other applicable code. QFPE shall witness and approve all testing. SOW sections 2.5.3 and 2.6.9.4 require testing to confirm two cross zoned heat detectors or activation of a manual foam releasing station will activate the foam system, but do not require actual discharge of water or foam.

Question: Are Hangar 3 or Hangar 19 (or any portion of those hangars) considered to be hazardous/classified locations per NEC? If so, please provide the hazard classification (Class / Division /

Group) and define the boundaries of the hazardous/classified area(s).

Answer: Up to 18" above the Hangar 19 floor is NFPA 70 Class 1 Division 2 requiring explosion proof equipment.

Question: Are Hangar 3, Hangar 19, and Pump House 212 provided with existing lightning protection systems?

Answer: No.

Question: RFP Section 7.4 indicates that, "There may be hazardous materials associated with this project." RFP Section 8.5 indicates that, "There is no known asbestos containing materials present in or around the building that could be affected in the performance of this work under contract." What are the potential hazardous materials that may be encountered? What if hazardous materials are discovered while performing work?

Answer: Both buildings 3 and 19 have sections of floor tile that are suspected asbestos‐containing material (ACM). There is no known ACM in pipe insulation or any other components of the building that will be affected in this project, however due to the age of the buildings there is potential to encounter hazardous materials such as ACM or lead based paint. Contractor shall follow industry standards to identify suspected hazardous materials, and if encountered they shall follow the differing site conditions procedures (give written notice to CO before conditions are disturbed and allow CO to investigate).

Question: RFP section 2.4.2 states that for new heat detector circuits, "all wiring shall be in minimum

3/4 inch or rigid conduit." Assuming that the hangars are not hazardous/classified at the roof level, is it acceptable to use 3/4" EMT with standard outlet boxes and compression fittings? Is there a requirement to provide a weatherproof conduit/raceway system for the heat detectors?

Answer: Government is not requiring any additional requirements above applicable code for heat detector conduit. RFP states EMT or rigid conduit is acceptable, depending on NEC requirement. If it meets NEC requirements and all other applicable code, EMT is acceptable. No weatherproof requirement above applicable code is required for heat detector conduit (RFP does specify requirements for pull station conduit).

Question: What is the Brand and Model of your fire alarm headend system?

Answer: AES Intellinet 7705i

Question: Will the government provide the building as‐builts?

Answer: Yes, they will be sent via AMRDEC on request.

Question: Who is responsible for providing fire watch when fire protection systems are impaired?

Answer: Contractor is responsible for fire watch during base business hours, and the Government is responsible for fire watch during non‐business hours. Liquidated damages may apply if fire watch period exceeds contract schedule.

Question: The existing fire alarm control panels are 20 years old. I have confirmed that replacement parts ARE AVAILABLE for these panels. Does the government want option pricing to upgrade the control panels to the latest version?

Answer: No, the panels are only intended to be replaced if necessary to meet the requirements of the scope of work. If replacement is necessary, that should be identified in the base bid.

Question: What is the scope and schedule of the AFFF bladder project?

Answer: That work is scheduled for 7‐17 Sep 2018. The expected scope of work is replacement of AFFF foam and foam bladder in both hangars.

Question: Are Hangar 3 and Hangar 19 considered to be "fueled" hangars?

Answer: Aircraft are drained of fuel when fuel cell work occurs in Hangar 19 or when they are doing major maintenance in Hangar 3, but are not fully drained of fuel when doing minor maintenance in either hangar.

Question: Would the base prefer to phase install so hangars are worked on at the same time or at different times?

Answer: For any work that prevents full usage of the hangar, different times would likely be more convenient to the Government, but it will depend on the operations at the time. Work that does not significantly impact use of the hangar can be done at the same time. Contractor’s construction schedule will have to be evaluated against the base maintenance schedule at the beginning of the project and re‐ evaluated consistently during construction.
