Ingredient materials for concrete are managed to maintain their
characteristics.
The production facility has the capability of producing
concrete in cold
weather.
The batching systems in operation are defined and measuring devices are verified for accuracy at stated frequencies.
The batching systems are capable of accurately batching
concrete without interferences.
The batching process complies with the required tolerances stated in
industry standards.
There are systems in place and operational to account for aggregate
moisture when batching concrete.
There are systems in place and operational to manage the required slump
and consistency of concrete.
Production facilities with a plant mixer (central mixing plant) is
of adequate condition to produce uniformly mixed concrete.
The production facility issues a delivery ticket that conforms
to the mandatory reporting requirements of ASTM C 94.
Evaluates the recording capabilities for batched materials at
the concrete plant and states such on the certificate.
That 90% of the delivery fleet operating from the plant maintain current certification.
The delivery fleet has the ability, via a visual inspection, to produce
uniformly mixed concrete and has necessary devices in proper operating
condition.
Requires attestation to the completeness of the inspection by a licensed
professional engineer.
Requires statement by a company official that the accuracy of measuring
devices will be maintained in conformance for the duration of the
certification.
Inspectors and their assistants have to go through a
qualification
process and be approved by NRMCA to conduct inspections for this program.
The qualification process requires a thorough reading of the plant
inspectors guide followed by answering a series of questions, submission of
a statement of qualifications and signing a pledge.
