Implementation of daylighting in hangar should be done to include South, East and West walls of B1007 per Tab A3 Elevation Model/Notional Concept. #97. Current version of UFC 4-010-01 is from 12 Dec 2018; vendor should use latest version of UFC 4-010-01 in consideration of a) glazing requirement of window/daylighting panels, b) door openings and c) exterior hardening. This requirement is amended/added into SOW.

Question #428: Page 50 of the Planning Charette indicates that the existing floor slab is sloped at 0.36%. The Planning Charette does not make it clear where this measurement was taken, and the plans only vaguely show slope arrows around the north end of the building (were not sure if these indicate new or existing floor slope).

With this information, and the fact that a physical site visit is not allowed, we dont have a way to accurately gauge the quantity of floor sloping materials required to meet the 0.5% slope requirements. If the Government can provide a drawing showing all existing floor sloping in the hangar, the following questions will be answered:

a. Where was the initial slope measurement high point measured from and in which direction(s)? b. Is the location noted High Point of Slab in TAB A1 the existing high point of slab? c. Assuming the existing high point of slab is the location shown on TAB A1, is the existing floor slab sloped at 0.36% on both sides (north and south) of this line? d. If the existing slope is not the same on either side of the line shown as High Point of Slab in TAB A1, please provide the existing slope north of this line. (note that the existing slope to the north of this line could impact the amount of sloping material well need on the south side of the line, as we may have to bring this high point up higher to achieve the required slope going both ways).

Answer #428: Slope arrows around north end of building indicate existing floor slope. A) From high point of slab toward hangar door; B) yes; C)assume yes; D) assume slab slope north of high point where aircraft nose is located DOES NOT require adjustment.

Question #479: Per Amendment 0005, Answers #362 and #363 indicate that no exterior concrete or asphalt paving work is required. However, per the Tab A2 Site Plan Map, there is new asphalt paving noted (i.e. for the tug route, the relocated parking spaces, etc.). Please reconfirm what asphalt and/or exterior concrete work is required, if any.

Answer# 479: See Amended SOW date 1 May 2020_exterior concrete paving work is required for dedicated tug route to flightline, walkways, and barrier curbs. Requirements have been added in SOW as 4.14 A, B, C, respectively.

Question #429: In order to slope the floor to the required 0.5%, existing expansion joints will have to be replaced. Does the grid pattern shown on the slab in TAB A1 represent the existing expansion joints? If not, please provide the locations of all existing expansion joints.

Answer #429: Assume Slabs grid patterns shown Tab A1 represent existing expansion joints.

Question #430: Q and A numbering in Amendment 0003 skips a lot of numbers (ex. Question #177 is followed by Question #203). Same thing with Amendment 0004. Are the skipped question numbers questions that are yet to be addressed?

Answer#430: Yes, skipped numbers are questions that are still waiting to be addressed.

Question #431: On future amendments where the Government modifies miscellaneous items in an attachment or section of the solicitation, can the Government please highlight the changes?

Answer#431: The areas that have been changed have been identified in Block 14 of the Amendment and updated attachments have been provided with associated Amendments. For future Amendments the Government will specify the page, section, and/or paragraph when possible.

Question #435: Are we to provide harnesses for the fall protection system and if so how many sets?

Answer #435: No, you are not required to provide harnesses.

Question #437: Loads to the steel frames. The as-builts for the hangars that are being referenced as comparison show that the structures are not the same as B1007. It is very likely the loads added to the structure because of added roof thermal insulation, automatic fire sprinkler system, foam suppression system, fall protection rails and heaters is anticipated to exceed beyond the 2.2 psf reserve capacity they discuss in Tab A original structural design loads. Structural as-builts and design calculations were not provided with the bid package, therefore the extent of structural modifications is unknown; how are we to quantify?

Answer# 437 No additional existing structural as-builts and design calculations are available; installation of structural frame reinforcement and/or purline to support and transfer additional loads from roof thermal insulation, automatic fire sprinkler system, foam suppression system, draft curtains, fall protection rails and heating elements is stated SOW, para 4.5.

Question #438: The metal wall panels in the video are aluminum, are the roof panels the same? There may be a concern with being able to walk on the roof to make repairs if its thin old aluminum.

Answer# 438: Assume Roof and Wall panels material identical Question #439: In the revised SOW it calls out for 25 each 10ft X 12ft panels, we dont think the panels are 10ftX12ft. Is this a type-o?

Answer# 439: panel size stated in revised SOW dated 1 May 2020 is the max ref; not actual size Question #440: In regards to Amendment 03 response to question #63 which states: Question#63: Page 50 of TAB A Planning Charette states that 10 foot CMU walls are required at all exterior walls. Attachment 1.3 the SOW, states that exterior walls are to be repaired only. Please clarify. Answer#63:See Revised SOW 17 April 2020, Page 6, Section 4.5 Architectural and Structural Works, D.

Answer# 440: See Answer #14 Amendment 0003.

Question #441: Exterior CMU Wall Repairs a. Added 1. For bidding purposes, assume 100 LF of CMU Wall requires repair Answer# 441: See Answer #14 Amendment 0003.

Question #470: BACKGROUND: Virtual Site Visit; TAB A2 - Site Plan Map. In the site plan map it reflects a new gate to be installed on the south east corner. In the Virtual Site Visit video, it shows a light tower approx.

center between Bldg. 1007s hanger door pocket and the rails and track assemblies for Bldg. 1005.

QUESTION:

a) There appears to be a new trench repair leading to it. What is it and how deep is it?

b) Since its not reflected in the site plan, please provide exact location in relation to the building and the door pocket.

c) Are we to relocate the light pole since it sits within the dedicated path of the new tug route?

Answer# 470: A) Structural concrete pavement on the airfield is typically 16 to 17 inches in this area. Shoulder asphalt is typically about 3 inches. However, the asphalt could be thicker, up to 6 inches, where it is used for structural pavement (for heavy aircraft). There may be isolated spots where that occurs. B) Hangar door pockets are on either sides of the buildings southern facing corners. C) Yes Question #442: Solicitation documents state exterior walls we must comply with UFC 4-211-01 - 3-3.2.3 which states; 3-3.2.3 Exterior Walls Provide a masonry or concrete finish up to a minimum 10 ft. (3.0 m) minimum above the finished floor for the interior and exterior face of the entire perimeter of the Aircraft Maintenance Bay, except at hangar doors. This includes the side/end walls, as well as the back wall which typically separates the Aircraft Maintenance Bay from shops and parts repair rooms. Question: Please clarify response given to question #63 and subsequent revised SOW which states to assume 100LF of CMU wall repairs. Existing CMU low wall was not constructed to support the additional weight of the anticipated 10ft+ high perimeter wall required to meet UFC requirements. For bidding purposes are we to assume low wall is sufficient and only needs repairs to 100LF, or are we to follow UFC requirements and provide costs to remove low wall and construct new 10ft+ perimeter walls?

Answer# 442: See Answer #14 Amendment 0003.

Question #443: Question: Please clarify response given to question #63 and subsequent revised SOW which states to assume 100LF of CMU wall repairs. Existing CMU low wall was not constructed to support the additional weight of the anticipated 10ft+ high perimeter wall required to meet UFC requirements. For bidding purposes are we to assume low wall is sufficient and only needs repairs to 100LF, or are we to follow UFC requirements and provide costs to remove low wall and construct new 10ft+ perimeter walls?

Answer# 443: Clarification: Assume 100 LF of 54 1/2inches tall, exterior CMU wall require repairs; new, 10-ft interior CMU wall, which separates aircraft from support facilities and be adjacent to the exterior CMU wall, is to be constructed.
