Matrix Service utilizes an Approved Supplier/Vendor List process for material suppliers and subcontractors. In order to be placed on the list, suppliers and subcontractors are required to complete the following:
Major Material/Fabrication Suppliers:
Submittal and approval by Matrix Service 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:
Due to the complexity and risk associated with the work performed by its Subcontractors, Matrix Service 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 Service 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.
