Level 1 Technicians conducting concrete testing for public and private projects must be certified as a Level I Concrete Field Testing Technician in accordance with Michigan Department of Transportation (MDOT), ASTM C94, ASTM C1077, and ACI specifications.
Course content for Level I is established by the American Concrete Institute (ACI) and MDOT.
Students pursuing Level I certification will be trained through a combination of classroom and laboratory instruction covering the following ASTM test specifications:
Sampling (C172) | Temperature (C1064) | Slump (C143) | Density (C138) | Concrete Cylinders (C31) | Air content-volumetric (C173) | Air content-pressure (C231)
In addition to these specifications, students will be introduced to the fundamentals of concrete including materials, curing, hot/cold weather concreting, and water/cement ratio calculations.
Technicians with little or no testing experience can prepare for attendance at a Level I class with the information below:
1. Review the MCA demonstration videos (see yellow button above) of the procedures for performing the seven ASTM Level I field tests.
Participants must successfully complete the following examinations in order to become certified as a Level I Concrete Field Testing Technician:
1. Michigan Fundamentals Examination
A 30-minute, “open book” exam consisting of 20 multiple choice questions covering the fundamentals of concrete. Students must score 70% or higher to pass.
2. ACI written Examination
A one-hour, “closed book” exam consisting of 55 multiple choice questions based on the seven field tests for concrete. Students must attain an overall score of 70% or higher and 60% or higher on each of the seven field tests to pass.
3. ACI Performance Examination
This exam consists of a verbal description of sampling procedures and a performance exam for the remaining six field tests. Students must successfully pass all seven performance tests.
