Specs 1.15 PERFORMANCE TIME A: Page 9 states: The Contractor shall complete the installation within one hundred and eighty (180) calendar days after Notice‐To‐Proceed. The time required for the Government to review, comment and approve the submittals, and equipment, and the ordering and shipping lead time will not be included in the Contractor’s performance time. Contractor shall submit construction schedule prior to Notice‐To‐Proceed. Specs 1.15 PERFORMANCE TIME B: Page 10 States: Notice‐To‐Proceed with the construction phase will not be granted until the Contractor certifies to the Contracting Officer that all required materials and equipment, as approved by the Government, are in his possession and ready for installation. Is it the intend that a contractor mobilize after preparing all materials and equipment onsite and then receive the NTP?

Answer: No. The Notice‐to‐Proceed will be granted when all submittals are approved and the FAA has completed the proper coordination for commencement of the project. The vendor will need to verify that all material will be available when needed prior to project start.

5 10/18/2021 9:19am CST

Note no. 3 in sheet C‐009 states that “If additional railing/toe boards or material need to be installed in compliant with OSHA.

Please clarify the scope of the work so that contactor can prepare an accurate proposal. Or can it be prepared with a unit price for each item

Railing and toe boards should be Osha compliant. Vendor to field verify.

6 10/18/2021 9:19am CST Note no. 4 in sheet C‐009 states that “Paint all surfaces of the existing railing system.” Since there is not complete drawing showing entire system and photos present partial images, can the cost be prepared with a unit price for each item.

No. The stairwell needs to be assessed, treated and painted in it's entirety.

7 10/18/2021 9:19am CST Note no. 5 in sheet C‐009 states that “Paint all surfaces of the existing staircase system.” Does it include catwalk? No. This scope does not include the catwalk.

9 10/18/2021 9:19am CST Verify the exact locations and quantity of wall mounted lighting fixtures in sheet E‐002. These wall mounted fixtures are located at the access doors and there are four of them. Vendor will need to verify.

10 10/18/2021 9:19am CST Sheet E‐003 doesn’t clearly indicate which items to be demolished and to be install as new. Please clarify. Can it be assumed that all items in one‐ line drawing to be new except the panels?

Yes, Leave the panels unless significantly corroded and in need of replacement.

11 10/18/2021 9:19am CST The detail 4 in the drawing C005: Please clarify the use of the "continuous Galv. Plate 3/16"X2" DIA 24". Shouldn't be welded to the new metal siding in lieu of the existing one? Is it meant to have air gap between the PVC corrugated siding and the 3/8" fanfold insulation. What is the DIA represent, is it diameter? please clarify.

After review with the structural engineer, the details specify 18" at detail on the new metal siding. DIA reference is not applicable.

12 10/18/2021 9:19am CST What is the total height of the wall from the concrete deck to the bottom of catwalk? Structure height to the bottom of the radome is 25" . This needs to be vendor verified prior to making any materials decisions.

13 10/18/2021

9:34am CST Will the existing steel decking wall be removed and replaced or the new insulation system will be on top of it? The interior steel (decking) wall will not be removed unless localized repair calls for removal to properly treat and repair the panel.

9:34am CST Will all the existing railings be painted or only the sections to be repaired?

All railing (excluding the catwalk) to be corrosion treated and painted.

15 10/18/2021

1:56pm CST

The demolition notes stated that retrofit needs to be done "section by section". Can the FAA define the length of a section?

Section is defined as half of the facility at a time. For clarification, the building is made up of 12 panels. 6 sections can typically be exposed at a time to support replacement. The recommended approach is to scaffold and sheath the facility to allow for sectional replacement. Sheathing the facility also allows for construction activities to occur while minimizing the impact from local weather conditions.

16 10/18/2021

1:56pm CST

The new outer wall is specified to be a: 4.2 X 1/16in x 3/16in PVC corrugated panel. Can the FAA verify the "1/16in" which is the depth of the panel? We believe it should be more than that. Please confirm.

See Attachment 8 cutsheet of a comparable item for specification purposes only. Note do NOT recommend any product or manufacturer. Correct profile is 4.2" X 1‐1/6" x 3/16"

Additional Questions

25 10/22/2021 12:50pm CST Detail 3/C005 states “Install 1/8”x12” Alum. Flashing”. The typical flashing thickness is 24 or 26 ga (1/64”). 1/8” seems like a typo.

If it needs to be beefed up, 16ga (1/16”) should be enough.

The design recommendation is 1/8” thick Aluminum sheeting which is approximately 3mm and 8 gauges.

26 10/22/2021 1:00pm CST

On sheet C005, detail 4/C005 a "Continuous Galv. Plate 3/16in x 2in DIA 24in" is specified. Can you please provide more information and/or a clarification detail of this element? Is it a plate or a pipe? Existing detail does not show the full extension of its installation and purpose.

Remove from new installation, no need for plate or weld. Reference is from original existing drawings which is no longer applicable.

27 10/22/2021 1:00pm CST On sheet C005, detail 3/C005 a "Welded Corner Galv. Plate" is specified. Can you please provide more information and/or a clarification detail of this element? Existing detail does not show the full extension of its installation and purpose.

Remove from new installation, no need for plate or weld. Reference is from original existing drawings which is no longer applicable.

28 10/22/2021 1:00pm CST Does the FAA have a specified/prefered manufacturer for the PVC Corrugated Panels? At this point, the only panels that we have found that can comply with the specified length are either white or gray.

The FAA does not recommend any specified/preferred manufacturer for the panels. The specification requires a Forest Green custom color, also meeting the National Forest requirement. An example of a company that provides panels is H&F Manufacturing. Contractor can use any Company for acquring the panels that meet the specifications. Contractor IAW submittal specifications is required to submit products for FAA approval.
