Interested parties must be registered in the Federal System for Award Management (SAM) and with H2C's vendor registration system. Submissions must include a statement of interest, a detailed capability and experience statement regarding high-temperature electrical heating and stainless steel fabrication, a Quality Assurance Program Manual, and a signed confidentiality agreement.
