TECHNICIAN CERTIFICATIONS REQUIRED FOR USACE LAB VALIDATION
Beginning in 2021, the MTC now requires that any lab (AASHTO accredited or not) requesting USACE Laboratory
Validation will be required to present non-expired American Concrete Institute (ACI) Certifications for
those areas of testing requiring such for any technicians working in the laboratory to be validated.
The MTC is aware that due to the COVID-19 Pandemic during the calendar year 2020, ACI training workshops and testing
sessions may be limited and acquiring certifications may be somewhat difficult during the calendar year 2021 and into the beginning of 2022.
The MTC will work with labs to accommodate these conditions. Please contact us for questions you may have on this requirement.
Currently, the ACI Certifications that will be required, along with the testing methods covered by
each, are as follows:
- 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.
