Outline: A detailed outline of the subject matter
covered by the exam, including the percentage of questions
from each content area and task.
01.
General Requirements Comply with special inspection requirements
of the enforcing jurisdiction. Review approved plans
and specifications for project details that pertain
to special inspection requirements. Notify the contractor
of deviations from approved plans and specifications.
If the deviations are uncorrected, notify the architect
or engineer of record and the building official
of deviations. Submit progress reports to the architect
or engineer of record and the building official,
describing tests that were performed and compliance
of work. Submit final summary report stating whether
work requiring special inspection was in conformance
with the approved construction documents and applicable
provisions of the building code.

Concrete Quality
Verify that individual batch tickets indicate delivery
of the approved mix as specified. Verify time limits
of mixing, total water added, and proper consistency
and workability for placement. Determine the required
type, quantity and frequency of tests to be performed
on fresh and hardened concrete. Observe sampling
of concrete, field testing of fresh concrete and
making of test specimens. Provide or arrange for
proper specimen identification, site storage and
protection, and transportation to the testing laboratory.
Provide or arrange for communication of field testing
results to the architect or engineer of record and
to the building official.

03.
Reinforcement
Verify that reinforcing steel and tendons are of
the type, grade and size specified and are in conformance
with acceptable quality standards. Verify that the
reinforcing steel and tendon system are fabricated
in conformance with acceptable quality standards.
Verify that at the time of concrete placement tendons
are free of oil, dirt and excessive rust, and are
properly coated and/or sheathed as specified. Verify
that reinforcing steel and tendons are located within
specified tolerances, and are adequately supported
and secured to prevent displacement during concrete
placement. Verify that minimum concrete cover is
provided. Verify that placement of reinforcing steel
and tendons (or ducts) comply with spacing, profile
and quantity requirements, as indicated by the installation
drawings and approved plans. Verify that hooks,
bends, ties, stirrups and supplemental reinforcement
are fabricated and placed as specified. Verify that
required lap lengths, stagger and offsets are provided.
Verify proper installation of approved mechanical
connections per the manufacturer's instructions
and/or evaluation reports. Verify that welds have
been inspected and approved as specified. Verify
that prestressed rock and soil anchors are fabricated
and installed as specified.

04.
Prestressing and
Grouting
Verify that the required concrete strength has been
attained prior to transferring prestressing forces.
Verify proper equipment calibration. Verify that
proper stressing (or tensioning) sequences are used,
proper jacking forces are applied, and acceptable
elongations are attained and recorded. Verify that
tendons and anchorages are properly sealed or otherwise
protected as specified. Verify that ducts, including
inlets and outlets, are of the required size, are
mortar-tight and are located correctly. Verify that
proper grout materials, strength and grouting pressures
are used as specified.

05.
Formwork, Joints
and Embeds
Verify that formwork will provide concrete elements
of the specified size and shape. Verify that the
location and preparation of construction joints
are in accordance with the approved plans, specifications,
and applicable codes and standards. Verify that
the type, quantity, size, spacing, condition and
location of embedded items are as specified.

06.
Concrete Placement, Protection and Curing
Verify acceptable condition of the place of deposit
before the concrete is placed. Verify that methods
of conveying and depositing concrete avoid contamination,
segregation of the mix, and displacement of reinforcement,
embedments and forms. Verify that concrete is
being properly consolidated during placement.
Verify that concrete is protected from ambient
temperature extremes during placement and curing.
Verify that concrete is being cured as specified
by approved plans, specifications and applicable
codes.
