Notice of Intent to Sole Source - Humboldt Mfg

The solicitation announces a sole‑source procurement for a Round Panel Determinate (RDP) test machine. The RDP machine will enable standardized testing of fiber‑reinforced shotcrete, allowing results from high‑energy deformation and impact drop test equipment to be correlated to an ASTM‑compatible method. This capability supports ongoing research at the Shotcrete Materials Research Division (SMRD) and provides industry stakeholders—mine operators, shotcrete suppliers, engineers, and ground‑control practitioners—with comparable performance metrics. The agency intends to acquire the equipment from Humboldt Manufacturing under a sole‑source justification. • Sole‑source award to Humboldt Manufacturing (ID 99670) • Equipment: Round Panel Determinate (RDP) test machine for shotcrete evaluation • Purpose: Standardize shotcrete testing, link specialized test results to ASTM‑based metrics • End‑users: Mine operators, shotcrete suppliers, engineers, ground‑control practitioners • No public bidding schedule, pre‑bid meeting, or site visit disclosed.
