1.4 N6275851556950 BN Justification_Redacted.pdf

This document is a Sole Source Justification form from NAVSUP Fleet Logistics Centers for Garnet Abrasive Grit used in surface preparation (blasting) operations. The requirement is specifically for GMA Garnet USA Corp's SPEEDBLAST 2TON BAG product, which must conform to MIL-PRF-22262 military specification. The form indicates that while other QPL-listed manufacturers exist, their abrasives have not met operational requirements in practice, thus justifying the sole source procurement.

The document details that alternative abrasives previously tested at the Ship Repair Facility (SRF) proved unsuitable due to repeated clogging from non-uniform particle sizing, and abrasive grains becoming embedded into hull surfaces, causing protective coating damage. By contrast, GMA SPEEDBLAST has demonstrated superior consistency, reliability, and performance across calibration, protective systems, and quality assurance procedures. The procurement is for the SRF-JRMC Yokosuka C500 activity, with a future document date of 7/2/2025, and is prepared by an Equipment Specialist to preclude competition to the maximum extent practicable.
