ACI Special Inspector study guide
ACI Special Inspector · Work through your exam, one topic at a time.
The Concrete Construction Special Inspector (CCSI) credential is one of the inspection programs administered within the ACI certification system, which the source describes as offering over 30 certification programs designed to form a minimum qualification for personnel employed within the concrete construction industry. Within that system, inspection programs are grouped separately from field and laboratory testing programs; the Concrete Construction Special Inspector sits in the Concrete Construction Inspection category alongside the Concrete Transportation Construction Inspector. The credential is aimed at personnel whose job is to inspect concrete installation and construction practices - verifying that work in the field conforms to project requirements and accepted practice - rather than at the technicians who perform and report field or laboratory tests. Because the exam draws on both inspection practice and the testing knowledge an inspector relies on, preparation should combine a working command of concrete construction inspection fundamentals with the field and laboratory testing knowledge that supports inspection decisions. The ACI Special Inspector study guide has 2 sections and about 628 words.
01Concrete Construction Inspection: Duties, Documents, and Field Controls
An ACI special inspector works for the owner (or the owner's agent), not the contractor, and documents whether work conforms to the approved plans, specifications, and referenced standards. Know the hierarchy: code and specifications govern, the approved drawings define geometry and reinforcement, and approved submittals and mix designs fill in details.

Understand slump (ASTM C143) as a measure of consistency, not strength; air content by pressure meter (C231) or volumetric method (C173); temperature; and density/yield (C138). Know that test methods specify the sample must be obtained and tests started within defined time limits after mixing, and that specimens must be molded, cured initially in the field, and transported without damage.
