As we prepare our proposal, we are experiencing a challenge related to the timing of subcontractor and vendor quotations. Many subcontractors and vendors do not release final pricing until one to two hours before our proposal is due. This significantly affects our ability to finalize our price volume, as we cannot determine which subcontractors or vendors will ultimately be included in our final pricing until just before submission.

Because the RFP requires the Small

Business Subcontracting Plan (SBSP) to be submitted with the Price

Proposal volume, contractors must either (1) base the SBSP on preliminary assumptions made several hours in advance of submission, or (2) submit the SBSP at a later time on bid day, once subcontractor and vendor selections are confirmed. To ensure full compliance, while providing the most accurate information possible, we respectfully request your guidance and preference: Submit our SBSP based on assumptions made prior to receiving final subcontractor and vendor pricing OR submit an accurate

SBSP by 5:00p EDT on bid day, once all pricing and selections are finalized.

Propose per RFP

Item 4-5

Please clarify the required degrees of freedom for the blade manipulator and scan system. As it currently reads, this specification could be satisfied with a total of three axes. Specifically, one axis to:

1) Move the source and detector along the length of the blade

2) Move the source and detector along the height of the blade

3) Rotate the blade

In practice, many more axes are typically provided to achieve the intended inspection coverage.

Also, is there a preference or requirement to have the gantry mounted source and detector manipulator mounted to the floor or ceiling? We interpret this as floor-mounted because it would interfere with the 2-ton internal bridge crane

22 P995, 3 41 34 23 1.3

Specification Section 41 34 23, Paragraph 1.3 requires the Paint Booth

Contractor (PBC) to perform a Hazard

Evaluation and Analysis in accordance with ANSI Z9.7, 29 CFR 1910.107, and NFPA 33, as well as a Dust

Hazard Analysis (DHA) in accordance with NFPA 652, Chapter 7.

However, the specification does not appear to provide sufficient Basis of

Design information necessary to perform these analyses. Specifically, the following information is not defined:

-Identification of processes that generate airborne particulates (e.g., sanding, grinding, composite repair, etc.)

-Characterization of particulate matter

(metallic, composite, organic, etc.)

-Material properties required for

DHA, including but not limited to Kst, Pmax, MEC, particle size distribution, 1 - Answered by Government in Specification. The specification explicitly defines

"Sanding Mode," "Spray

Mode," and "Brush/Roll

Painting Mode" as required operational modes (Section

1.7.3). These are the core processes the system must be designed to handle.

2 - Responsibility of the

Contractor. The specification provides a detailed list of all metals, composites, coatings, and adhesives to be used

(Section 1.3). It is standard practice for the expert contractor to be responsible for obtaining the Safety Data

Sheets (SDS) for these specified materials to conduct their analysis.

3 - Responsibility of the

Contractor. The Government and combustibility classification

-Safety Data Sheets (SDS) or emission data for coatings, adhesives, and associated materials listed in

Paragraph 1.3

-Expected concentrations, generation rates, or operational scenarios for both particulates and vapors

-Confirmation whether combustible dust conditions are anticipated within the paint booth

As these inputs are required to determine compliance with NFPA 652, NFPA 33, and ANSI Z9.7—including evaluation of recirculation permissibility, explosion protection requirements, and ventilation system design—the Contractor is unable to fully develop the required analyses or accurately size and price the system.

Request:

Please provide clarification and/or supplemental information regarding the Basis of Design for the required

Hazard Evaluation and Dust Hazard

Analysis, including:

1. Identification of all dust- and vapor-generating processes to be performed within the booth

2. SDS documentation for all coatings, solvents, adhesives, and materials listed in the specification

3. Characterization of expected particulate types and whether combustible dust is anticipated

4. Any available existing Hazard

Evaluations, Dust Hazard Analyses, or environmental/air permitting studies

5. Confirmation whether exhaust air recirculation is intended to be permitted as part of the design

Alternatively, confirm that the

Contractor may base the Hazard

Evaluation and Dust Hazard Analysis on reasonable industry-standard assumptions, and that any impacts resulting from actual material properties or regulatory requirements will be addressed as a contract modification.

has characterized the particulate types by listing the materials (e.g., Nickel, Titanium, Carbon Fiber) in

Section 1.3. The core task of the DHA, which the contractor must perform per NFPA 652, is to analyze these materials to determine if they are combustible and what their properties are. The

Government does not need to pre-determine this; they are paying the expert contractor to make that determination.

4 - Answered by Government in Specification. The specification does not reference any existing studies.

Instead, it explicitly requires the PBC to "perform a Hazard

Evaluation and Analysis" and submit a report for approval

*before* developing their design (Section 1.3 & 1.8.b).

This makes it clear that a new analysis is a required deliverable of the contract.

5 - Answered by Government in Specification. The specification confirms that recirculation is a key design requirement. It specifies "80%

Recirculation" for both Spray and Brush/Roll modes

(Section 1.7.3) and outlines the NFPA 33 requirements that must be met for this to be permissible (Section 1.7.4.d).
