Approved Supplier Process

Matrix NAC utilizes an Approved Supplier/Vendor List (AVL) process for material suppliers and subcontractors.  In order to be placed on the AVL, suppliers and subcontractors are required to complete the following:
 

Major Material/Fabrication Suppliers:

  • Submittal and approval by Matrix NAC of a completed Supplier Prequalification Questionnaire.
  • Third Party Accreditation (ASME, ISO, AISI, SISAP) based on receipt of accreditation certificate and registrar listings.
  • Acceptable shop survey by way of on-site assessment of supplier’s capabilities.

 

Subcontractors:

  • As a union construction company to the North American energy, power and industrial markets, Matrix NAC requires our subcontractors to be union subcontractors in accordance with collective bargaining requirements.
  • Due to the complexity and risk associated with the work performed by its Subcontractors, Matrix NAC follows a rigorous process to admit Subcontractors to the Approved Supplier (Vendor) List:
    • Subcontractor’s that fall into the Tier I Medium/High Risk exposure category (see chart below) are required to complete their prequalification process through ISNetworld. Matrix NAC requires an A or B rating in accordance with our ISNetworld requirements.
    • If the Subcontractor falls into the Tier II Low Risk exposure category, inclusion in ISNetworld is not mandatory, but the Subcontractor must complete a manual prequalification process to be reviewed by Procurement and other departments as needed.
