Forward Hadronic Calorimeter Absorber Structures

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the technical specifications for the FHCAL, specifically concerning materials and compliance standards for RFP 457842.

• Paragraph 3.2 - Materials (AISI 1020 Steel):
  • The required specifications in Para 3.3 apply only to Plate thicknesses, not the 14 Ga (0.0747") material.
  • Magnetic Permeability testing for Grade 1020 steel is not standard and is costly ($2400 per test, 4 samples per heat lot), with results provided "For Information Only".
  • The SOW and Specification documents are being revised based on this feedback.
• Paragraph 3.3 - Code/Standard Compliance:
  • ASTM A6 does not apply to 14 ga sheet; ASTM A1011 (hot rolled) or ASTM A1008 (cold rolled) should be used instead.
  • ASTM A773 (Magnetic Permeability) testing requires samples to be evenly spaced across sheets and can be arranged through third-party facilities.
  • For ASTM B733 (Nickel-Phosphorus Coatings), plating ideally uses the threaded holes; secondary coating is not necessary, and thickness testing can be done on samples.
  • ASTM A830 applies to Grade 1020 plate but not the 14ga 1020 sheet.
• Paragraph 4.1.2.1 Acceptance Tests:
  • Magnetic permeability samples should be spaced out across the heat and not be too close to each other.

This Q&A document indicates that the SOW and Specification documents are being revised, which may impact the requirements and details of the solicitation. Bidders should refer to updated documents for definitive specifications.
