Given age of the shop area addition and previous asbestos testing (see report provided per RFI 8), further ACM is not anticipated. If the contractor identifies additional ACM, an equitable adjustment will be negotiated for any required abatement. | N/A |

| 3 | The drawing show the lightning protection being removed and then reinstalled after the new system is in place. Is the existing lightning protection being reused or is it new? If reused, does it have to be recertified? | 14-Feb-24 | 26-Feb-24 | In general, the lightning protection system is new. Refer to Existing Keynotes throughout the drawing set for select components of the existing system that are to remain (Examples: most down conductors, but not all, and some air terminals). Specification section 26 41 00 outlines the testing requirements. | N/A |
| 4 | For bids being submitted by courier, please provide delivery address. | 15-Feb-24 | 26-Feb-24 | The address is on page 9 of the SF1442, paragraph 4.3 under the "Instructions to Bidders". | N/A |
| 5 | Is there a staging area available on site to store mechanical equipment, or must all mechanical equipment be moved off-site and stored by the contractor for later reinstallation? | 16-Feb-24 | 26-Feb-24 | Outdoor staging areas on the installation, in the vicinity of the project site will be made available to the contractor. | N/A |
| 6 | Will temporary protection be required at entrances? Can entrances to the existing building be closed? Please clarify what entrances must remain open, and what entrances may be closed during construction. | 16-Feb-24 | 26-Feb-24 | The main entrance and airfield side entrance must remain usable during construction, provide protection if/when construction activities would create a hazard at these locations. Other entrances are to remain available for emergency egress, but may be closed for routine use when work effects these areas. | N/A |
| 7 | Please confirm if mechanical TAB / commissioning pre and post verifications should be made to existing equipment being removed from the roof, to confirm operation prior to the contractor moving equipment off the roof and to confirm operation following reinstallation of equipment? | 16-Feb-24 | 26-Feb-24 | Pre- and Post TAB is required on all equipment that is to be removed and re-installed. If an item is to be demolished it does not need to be TAB'd | N/A |

| 9 | the contract documents do not discuss any phasing requirements specific to the timing of the removal and reinstallation of the rooftop HVAC equipment. Are there any phasing or outage timing requirements for this rooftop equipment? | 16-Feb-24 | 26-Feb-24 | Specific phasing is not required. However, interruptions and outages should be minimized to that which is reasonably necessary for the diligent completion of the work. Coordinate with the Government during construction as indicated in the project documents. Note that the majority of the spaces under Roof 1 have been temporarily vacated and present less of a concern for interruption of Government operations than Roof 2 & 3. | N/A |
| 10 | The specifications call for 1/4” per foot tapered insulation with an R-30 base. Our concern is that this will result in an insulation height that exceeds the wall height. Will it be acceptable to use 1/8” tapered insulation in lieu of 1/4” to reduce the overall height of the insulation at the walls? | 15-Feb-24 | 26-Feb-24 | Per UFC 3-110-03 section 6-4-4, a 1/4":12 slope is the minimum allowable slope where 1/2":12" slope cannot be achieved. Section C402.2.1.1 of the 2021 IECC allows the R-value calculation to use average thickness of the roof insulation; therefore, an R-30 base would not be required in all areas of the roof. Coordinate with roofing manufacturer for insulation calculations and design. |
| Th existing roof structure is also sloped. Please see drawings "SZDT001064 ADAL Aircraft Maintenance Hangar 254 - Reference Drawings.pdf" provided with the solicitation. | N/A | |||||

Glycol should be drained and stored for reuse as necessary for removal of the solar collectors to allow the roofing to be replaced. After the roofing is replaced reinstall the collectors and refill with salvaged glycol. | N/A | |
