A Concrete Construction Special Inspector is a person qualified to inspect and record the results of concrete construction inspection based on codes and job specifications. The program covers inspection during pre-placement, placement, and post-placement operations.

A Concrete Construction Inspector-in-Training is a person who is knowledgeable about inspection procedures for concrete construction, including pre-placement, placement and post-placement operations; but does not have the experience required to qualify as an ACI Concrete Construction Special Inspector.

The programs require a knowledge of concrete construction, including plans reading, formwork installation and removal, reinforcements, embedments, sampling and testing freshly mixed concrete, conveying, placing, consolidation, finishing, jointing curing, and protection.

The technical resource materials used in these programs include the following:

Certification Requirements

Concrete Construction Special Inspector

ACI will grant certification only to those applicants who:

• Hold current certification as an ACI Concrete Field Testing Technician Grade I
• Obtain a passing grade on the written inspection examination
• Obtain a passing grade on the written plans reading examination
• Possess at least one of the following qualifications
  • A minimum of two years of college or technical school, earning at least 60 credit hours, plus two years of satisfactory work experience, or

  • Proficiency in appropriate areas of concrete construction inspection

Verification of the amount and range of work experience by the applicant's employer(s) is required.

The three-hour written inspection examination is "open book" and consists of approximately 80 multiple choice questions. The one-hour plans reading examination consists of approximately 20 questions and is designed to test the examinee's ability to read and understand engineering drawings. The minimum passing grade for each examination is 70%.

Concrete Construction Inspector-in-Training

ACI will grant certification to those applicants who meet the Field Technician prerequisite and pass both written examinations. Individuals with Inspector-in-Training Certification can upgrade to full inspector status upon submittal and approval of sufficient education/work experience.

Recertification is necessary every five (5) years, and requires successful completion of the written examinations.

If you pass the exam, you will be issued a certificate from ACI international qualifying you as a Concrete Construction Special Inspector.
