On Attachment ‘D’ Small Biz Plan, pg. 1. Are we to include 20% or 30% for Small Business…under the Sample Dollars / NASA goals…it shows under *To all Small Business = $300,000 and 20%? Please clarify.

The intent of the Sample Subcontracting Plan that was provided as Attachment D to the Final RFP, is to assist potential offerors in creating a Subcontracting Plan that meets all of the requirements listed in FAR 19.704 and FAR 52.219‐9. The example shown on Attachment D Page 1 of 13 is for informational purposes only and does not accurately reflect the goals for this project. For the example shown on Attachment D Page 1 of 13, please substitute 30% in place of 20%, so the math is correct.

Please confirm if the 450 calendar day completion date is considered to start after the Construction Notice to Proceed is issued.

As stated in Clause B.6, the Contractor shall complete the entire work ready for use within 450 calendar days after the first Notice to Proceed is issued.

56 M‐02 ceiling calls for the panel size to be 24”x20” which does not exist. What size panel was intended for use? Panel size shall be 24" x 120" for M‐02 ceiling.

Detail 6/A502 indicates gray silicone sealant. Specification sections 08 81 00 and 08 44 23.98 do not indicate that gray sealants and/or gaskets are required. Please confirm if gray sealants are required for insulated glass units and curtain wall sealants as well as gray curtain wall gaskets; Black is the standard for both

Gray is required for all sealants and/or gaskets

The Door Schedule, sheet A‐601, indicates aluminum door types B and C as having a thickness of 2‐3/8”.

Specification 08 11 16 Aluminum Doors, section 2.4.2, indicates the door thickness at 1‐3/4”. Which is correct? 2‐ 3/8” aluminum doors are considered themally improved.

Aluminum door types B and C shall have a thickness of 2‐3/8”. The schedule listing 2‐3/8" is correct.

Specification 08 81 00 Glazing, section 2.4.5, indicates all glazing gaskets are to be “One‐Piece” (Vulcanized Gaskets/Pre‐molded Corners). This is not possible with the specified curtain wall systems. Since the curtain walls are two‐sided and four‐sided SSG systems, which equates to using what is termed as “Cassette” by some curtain wall suppliers and “Toggle” by other curtain wall suppliers. This means the glass will be shop applied with structural sealant to a perimeter frame; therefore, no gaskets involved with this portion. These perimeter frames that are adhered to the back of the glass will be attached to the main curtain wall members in the field using either a cassette clip or toggle type fastener. Field applied silicone sealant will then be applied between the glass joints. Since face caps only occur at the sill and vertical members in some occasions, it is not possible to have “One Piece” gaskets. Those types of gaskets are only meant for systems that do not have applied pressure plates or are only meant for the back‐member portion of the curtain wall systems

With the understanding that Specification 08 81 00 Glazing, section 2.4.5, which indicates all glazing gaskets are to be “One‐Piece” (Vulcanized Gaskets/Pre‐molded Corners), cannot be met with the specified curtain wall systems, Silicone Sealant is acceptable in place of gaskets for this specific situation.

Specification 08 80 00 Glazing:

a. IGU‐2 – White Silkscreen

b. IGU‐4 – White Spandrel

c. IGU‐3 – White Silkscreen

d. It is the recommendation from both the manufacturer and installer that White spandrel and silkscreen be applied to low‐iron glass; otherwise, the white tends to appear green when applied to standard clear glass.

Regarding Specification 08 80 00 Glazing, the white silkscreen (IGU‐2, IGU‐3) and white spandrel (IGU‐4) on standard clear glass shall be provided.

Would NASA and Bialosky be open to running the vertical curtain wall mullions continuous from level 1 to the roof in lieu of the interruption that is detailed on wall section 2/A‐408 and detail 3/A‐503? . This would be the aluminum curtain wall on column line BG from 1 to 10 and from 11 to 13.

a. This method would eliminate the 3”x3” x3/8” hss tube steel as we would connect our curtain wall to the web beam under the floor slab.

b. This would simplify installation in our opinion.

c. The clip for the louver fins could be one of the curtain wall manufacturers standard brackets back to the curtain wall

The suggestion of running the vertical curtain wall mullions continuous from level 1 to the roof in lieu of the interruption that is detailed on wall section 2/A‐408 and detail 3/A‐503 is not acceptable. The detail provided is required to support the vertical fins at the mid‐point and shall not be changed.
