TECHNICIAN CERTIFICATIONS REQUIRED FOR USACE LAB VALIDATION
The MTC now requires that any Laboratory (AASHTO accredited or not) requesting USACE Laboratory Validation will present
non-expired American Concrete Institute (ACI) Certifications for those areas of testing requiring such certifications.
The Laboratory must have a minimum of two technicians on staff that have the required certifications, based on the test methods
performed by the Laboratory, as indicated below:
- Aggregate Testing Technician Level 1 ---- aggregate testing including ASTM D75, C702, C117, C127, C128, C136, C566, and C40.
- Aggregate/Soils Base Testing Technician ---- soils testing including ASTM D75, C702, D421, D422, D4318, D2216, D698, and D1557.
- Concrete Strength Testing Technician ---- concrete strength testing including ASTM C617, C1231, C39, and C78.
- Concrete Field Testing Technician Grade 1 ---- fresh concrete testing including ASTM C172, C1064, C143, C138, C231 and/or C173, and C31.
Laboratories that do not have these certifications in place cannot be validated for those methods covered by these certifications until they are in place.
Proof of enrollment/payment for a certification testing event will not be accepted for validation, only final certifications of the technicians doing the testing will be accepted for this requirement.
These certification requirements are subject to revision or change at any time, so please check the MTC website prior to requesting validation of a new laboratory or revalidation of an existing validated laboratory.
If the Laboratory has specific questions or issues concerning this policy, please contact the MTC to discuss further.
