ACI-301 and ASTM C-94 vs ACI-318 and IBC

ACI-301 and ASTM C-94 vs ACI-318 and IBC

ACI-301 and ASTM C-94 vs ACI-318 and IBC

(OP)
I compiled the below information for another forum question but thought I’d ask something else about it here.  ACI-301 and ASTM C-94 require CERTIFIED techs for performing field tests but the building code, ACI-318 and IBC, only require QUALIFIED techs for the same tests.  What is the significance of the difference in the wording, if any?   

ACI-301
1.6.2 – Field tests of concrete required in 1.6.3 and 1.6.4 shall be made by an ACI Concrete Field Testing Technician Grade 1 in accordance with ACI CP1 or equivalent.

ASTM C-94
16.2 – Tests of concrete required to determine compliance with this specification shall be made by a certified ACI Concrete Field Testing Technician, Grade I or equivalent.

ACI-318
5.6.1 — Concrete shall be tested in accordance with the requirements of 5.6.2 through 5.6.5. Qualified field testing technicians shall perform tests on fresh concrete at the job site, prepare specimens required for curing under field conditions, prepare specimens required for testing in the laboratory, and record the temperature of the fresh concrete when preparing specimens for strength tests. Qualified laboratory technicians shall perform all required laboratory tests.

R5.6.1 — Laboratory and field technicians can establish qualifications by becoming certified through certification programs. Field technicians in charge of sampling concrete; testing for slump, unit weight, yield, air content, and temperature; and making and curing test specimens should be certified in accordance with the requirements of ACI Concrete Field Testing Technician—Grade 1 Certification Program, or the requirements of ASTM C 1077,5.3 or an equivalent program. Concrete testing laboratory personnel should be certified in accordance with the requirements of ACI Concrete Laboratory Testing Technician, Concrete Strength Testing Technician, or the requirements of ASTM C 1077.

5.6.1 Laboratory and Field Technicians
The concrete test procedures prescribed in the code require personnel with specific knowledge and skills. Experience has shown that only properly trained field technicians and laboratory personnel who have been certified under nationally recognized programs can consistently meet the standard of control that is necessary to provide meaningful test results. In the ’02 code, provisions in 5.6.1 were added to require that tests performed on fresh concrete at the job site and procedures required to prepare concrete specimens for strength tests must be performed by a “qualified field testing technician”. Commonly performed field test which will require qualified field testing technicians include sampling of fresh concrete; testing for slump, air content and temperature; and making and curing test specimens. Field technicians in charge of these duties may be qualified through certification in the ACI Concrete Field Testing Technician – Grade I Certification Program. Section 5.6.1 also requires that “qualified laboratory technicians” must perform all required laboratory tests. Laboratory technicians performing concrete testing may be qualified by receiving certification in accordance with requirements of ACI Concrete Laboratory Testing Technician, Concrete Strength Testing Technician, or the requirements of ASTM C 1007.

IBC 2003 - 1905.6.1 Qualified technicians.
Concrete shall be tested in accordance with the requirements in Sections 1905.6.2 through 1905.6.5. Qualified field testing technicians shall perform tests on fresh concrete at the job site, prepare specimens required for curing under field conditions, prepare specimens required for testing in the laboratory and record the temperature of the fresh concrete when preparing specimens for strength tests. Qualified laboratory technicians shall perform all required laboratory tests.

RE: ACI-301 and ASTM C-94 vs ACI-318 and IBC

ACI 301 is a specification while ACI 318 and IBC are building codes.  The building codes direct the engineer to make sure that the inspectors are qualified. The engineer's specification says how they are qualified.  If the engineer chooses to use ACI301 as part of the specification, 301 says that qualification is determined  by certification.
