Page Section Paragrap h

Per the project Solicitation, the minimum small business participation requirement, through work performed by the small business prime and/or subcontracting with small business, shall meet or exceed 20% of the total contract value. With the inclusion of both a Project Labor Agreement (PLA), and Cybersecurity Maturity Model Certification (CMMC) requirements, many non-union, small business firms are reluctant to sign and/or comply. We request the minimum small business participation requirement to be reduced due to these competing requirements.

The solicitation remains unchanged.

Propose per RFP.

Steel posts are required for the roof framing at the tall end of the stair shaft roofs (see PSF121 and PSF401). The only detail for the tall end of the roof, C1/PSF411, does not indicate any embed plate size or connection requirements.

Please provide required embed plate size and detail. Note there is a detail B2/PSF501 that may be the detail, its just not cut from anywhere. Please confirm.

The carried column indicated on the plan north end of 'Typical Stair Roof Framing Plan' on PSF401 and PSF401Y is a Galvanized HSS4x4x1/4. B2/PSF501 is the 'Typical Carried Column Detail' and would apply for the support of the HSS4x4. The embed plate in detail B2/PSF501 must be galvanized. On sheet PSF401 and PSF401Y and the associated 'Typical Stair Roof framing Plan', revise the size of the HSS8x4 on the plan east and plan west sides of the plan to HSS8x8x1/2. All the joists and HSS members indicated on the 'Typical Stair Roof Framing Plans' must be hot-dipped galvanized.

The HSS framing penetrates the precast wall panels on OSF101A. The framing will have to go up first since there is no way to access the steel after the walls are

up. Looking at OAE221 and OAE224, these wall panels are solid panels, they would need to be split at the beam penetration at the wall in order accommodate this condition. Please provide updated panel layout and in addition, at detail needs to be provided showing other elements at this interface.

Please clarify.

Revise the end of the two HSS girts to be connected to the face of the precast panel. Design the embed plate for a vertical load of 5 kips and a combined horizontal ultimate load of 5 kips.

Weld the HSS all around to the embed plate with 1/4" diameter fillet weld.

An alternate bolted connection may be designed and submitted for review.

2.13.1 appears to include generic requirements for fire alarm/mass notification speakers. Please clarify performance criteria and basis of design for "ceiling mounted speaker clusters".

PENDING RESPONSE

Fire alarm/mass notification system matrix on drawing FA502 refers to "fire pump supervisory signals". The Project doesn't appear to include new fire pumps; please clarify requirement for fire alarm supervision of fire pumps.

Fire pump supervision is not required.

Hangar, OSF, and parking garage drawings (multiple disciplines) require "exterior exposure corrosion protection and control in accordance with an environmental severity classification (ESC) of C4 for building systems and components" in several areas. Please clarify required corrosion protection and control methods.

Corrosion protection and control methods are outlined throughout the specifications for the applicable building systems and components.

Please differentiate the four dry pipe sprinkler systems shown on parking garage drawing PFX501 (Volume 4). It's unclear which part of the building is served by each system.

Each system serves half of a level of the parking garage (less than 52,000 sq.ft. per system in accordance with NFPA 13 requirements). Final configuration of the system piping is the responsibility of the contractor.

Please clarify routing of vertical distribution for fire protection system piping in hangar (Volume 2B) and parking garage (Volume 4). It's unclear where sprinkler system risers will penetrate each floor.

Second floor fire protection piping in the hangar penetrates the floor in Mech

243. Second level fire protection piping in the parking garage penetrates the floor of the parking space plan east of column line 5.

Parking garage fire protection drawing PFX121 appears to show interior hose connections along column line B. Please confirm whether interior hose connections are required.

Interior hose connections are not required.

87 09 09 00 3.3.3

Section 3.3.3 09 90 00 Indicated the cleaning and prep requirements for galvanized metal that shows damage.

Please confirm that if galvanized coating is in tact it does not require a top coat of paint and can remain exposed.

Galvanized steel requires top coats under 09 90 00, 09 96 00, and 09 97

13.27 respectively.

88 13 49 20.00 10

For example, electrical power drawing EP102E only appears to show power filters at the three interior secondary containment spaces, but not at the perimeter of the primary containment space.

See response to PPI#52.

89 AE611 13 49 20.00 10

6 & A1/AE611 – RF Window – Please confirm that the basis of design for the RF/STC window is Krieger. This window is tested at 68 dB to 95dB with IEEE-299 standards. If this is not the basis of design, please specify correct product. If it is the BOD, please note that it fails short of the RF shielding requirement.

This is a performance based specification. Refer to Section 13 49

20.00 10 as provided in the solicitation.

90 Amendment 2

Per Amendment 2, RFI #2, it appears the proposal due date will remain unchanged.

This will not allow adequate time to finalize negotiations with the local union for a PLA, and engage compliant/willing subcontractors to participate in the procurement. Additionally, with the inclusion of CMMC Far Clauses, it is abundantly clear that most of the subcontracting community is not currently registered/self-assessed or compliant with CMMC which will not support the requirements of the solicitation, as per the FAR, is required prior to an award. If the proposal due date is not extended, it is unlikely the project will have adequate compliant interest from the subcontracting market.

See Response to PPI #27.

91 2127 13 1.4

May framing for tensioned fabric structures be excluded from additional protective packaging since standard industry practice is to ship them in bundles and the steel framing does not require additional protection?

PENDING RESPONSE

92 2128 13 2.1 a.

The overall exterior width and interior minimum clear dimension both state 60'.

The adjacent flightline has existing 60' wide structures which clear 56' inside. Will 64' wide structures clearing 60' width inside be sufficient while still meeting airfield clearance requirements?

PENDING RESPONSE

93 2128 13 2.1 a.

Can the structures reach 30.5' exterior height? This allows the frame to clear 28'6" at the peak.

Provide interior clear dimensions per 2.1a. Frame dimensions to be confirmed with the engineered shop drawings.

94 2128 13 2.1 a.

Fabric is described as a "laminated " fabic cover, which is inconsistent with a coated 28oz./sq. yd. material described in 2.3.1.

Please confirm "coated" material is correct since lamination is a different process used on lighter weight materials.

PENDING RESPONSE

95 2129 13 2.4

The stated design requirements for the lightning protection system do not match the actual air terminal placement for a code compliant lightning protection system. Is the lightning protection system to be installed to match the previously protected shelters? Additionally, aluminum materials must be used due to corrosion of dissimilar metals (copper cannot be used on galvanized steel).

The lightning protection system must be designed and installed to comply with NFPA 780 and to receive a UL Master labeled once installed.

Aluminum is acceptable as a substitute for copper to avoid corrosion due to dissimilar metals.

96 Site Walk

During the site walk, it was indicated that the 2nd tier security fence would be relocated by the GC for the duration of the project.
