9. Is there a requirement for painting the North and South hangar doors inside H16? If so, one paint color or two paint colors?

The hangar doors are not in the scope of work.

10. Paragraph 7.12 requires hangar ceiling to be surface mounted high-impact wood fiber panels, please clarify?

The panels should withstand highly exposed humidity and sag resistant.

11. Will insulation be required over the top of the new hangar ceiling system?

The Insulation is not required.

12. Paragraph 7.13 requires new LED lighting system in the entire hangar, is LED lighting required throughout the renovated spaces?

Correct.

13. Paragraphs 7.1 and 7.2 require the existing HVAC system serving the two-story module building to be removed. The two-story module building is currently served by three (3) split-DX systems. Is the new HVAC system required to be zoned similar to how the current HVAC is serving the two-story building?

The 3 existing split DX systems are to remain. The new HVAC system will service the same areas that the demolished system served.

14. The existing HVAC systems serving the two-story module building do not have ventilation air. Does the facility typically operate with the main hangar doors open such that provisions for ventilation air could be ducted to receive ventilation air from within the main hangar or will ventilation air need to be ducted to the receive fresh air from the exterior of the main hangar/building?

The ventilation from within the hangar would be fine. We work with the doors open in the warmer months.

15. For bidding purposes, does the Government have structural drawings of the 2-story building in the interest of verifying the existing structure can support the weight of a larger HVAC system?

The government does not have existing structure drawings for the 2-story building.

16. Paragraph 7.9 requires ventilation/exhaust in the Pneudraulic Room. The existing fan coil unit serving the building where the Pneudralic Room is, does not have fresh ventilation air ducted to the system. Is it the intent of the SOW to duct fresh ventilation air to the HVAC system or simply add an exhaust fan with provision for make-up air to the Pneudraulic Room? If it is the Government’s intent to have fresh ventilation air ducted to the HVAC system, the unit will be required to increase in size. Adding an exhaust fan to serve the Pneudraulic Room will cause the Pneudraulic Room to become negatively pressurized pulling air from the adjacent spaces. The adjacent spaces will have excess infiltration that the HVAC is not currently sized to handle.

Existing HVAC system will be disconnected from the Pneudraulic Room. Contractor shall design a new separate HVAC system for the Pneudraulic Room to separate from the rest of the building. New system shall include exhaust, fresh ventilation air and temperature exchanger.

17. The restrooms are required to be renovated to comply with ADA standards. Is the shower required to comply with ADA standards?

21. RFP Para. 7.16 states to add 5 additional data drops in the LOX Room. Please confirm the existing telecom equipment has capacity/space to connect 5 new data drops or if a new patch panel is required.

There is adequate space for the lines.

22. Specification section 27 10 00, Para. 1.6.1.2 of the RFP requires an RCDD to perform the telecommunication design. Since the scope of the communication work is only 5 new data drops connected to existing equipment, can the electrical DOR design the telecom portion of the RFP?

The electrical DOR can design the telecom portion of the RFP.

23. RFP requires contractor to relocate entire existing tire shop from the south side to the north side of the hangar. During the site visit we observed several pieces of equipment, tire racks, a modular trailer, etc. within this space. In order to quantify the level of effort necessary and the utility location that will be required, please provide an equipment list inclusive of all elements in the tire shop that will require relocation.

Prior to construction, the government will relocate all the rolling tool boxes, tires, furniture, and computer equipment. Contractor shall responsible to relocate everything else.

24. Statement of Work requires the installation of metal wall panels over existing windows on both side of the hangar to be painted egg shell white. Is it acceptable to install a pre-finished white metal wall panel?

Pre-finished white metal wall panel is acceptable. The new metal panel color shall match the new Base approved Egg white shell.

25. During the site visit, it was observed that there were hoists already located on both the north and south side of the hangar. On the south side of the hangar, both hoists appeared to be newer than the hoist on the north side. Please confirm that moving the hoist on the north side to the south side is desired.

Relocate the hoist to the south end of the hangar.

26. The Hazardous Material Report on Page 1 states that all light fixtures must be checked for PCB Ballasts and if ballasts are not marked as “NO PCBs” they must be handled and recycled per the report. As we have no way of quantifying this prior to bid, should we assume all lights have PCB Ballasts? Or should we assume that none have PCB ballasts and that if they are encountered it will be handled via a change order?

Assume all light fixtures have PCB ballast.

27. Statement of Work paragraph 6.7 requires that the contractor demolish the existing hard ceiling in the entire hangar area. There are items hanging around the entirety of the hangar. Please confirm if any items are suspended from the ceiling or are all items suspended from the structure above?
