CCI Inspection Techniques & Procedures 3

Question 1

When inspecting driven pile installation, the inspector should record the number of blows per foot primarily to:

Accepted Answer

Calculate bearing capacity using driving formulas

Answer

Blow count per foot is used with driving formulas (e.g., ENR or WEAP) to estimate the bearing capacity of driven piles.

Question 2

Which condition requires an inspector to STOP work immediately on an excavation in a Type C soil?

Accepted Answer

No sloping, benching, or shoring present in an excavation over 5 feet deep

Answer

OSHA requires excavations in Type C soil deeper than 5 feet to have adequate cave-in protection; absence of protection is an imminent danger.

Question 3

A slump test on a concrete batch shows 5 inches when 4 inches is specified with a ±1-inch tolerance. The inspector should:

Accepted Answer

Accept the load since it is within tolerance

Answer

A slump of 5 inches falls within the ±1-inch tolerance of the 4-inch specification (acceptable range 3–5 inches), so the load should be accepted.

Question 4

When inspecting masonry construction, the inspector verifies that mortar joints are tooled at the CORRECT time. What is that time?

Accepted Answer

When the mortar is thumbprint hard

Answer

Mortar joints are tooled when thumbprint hard to compress the mortar surface and improve weather resistance and bond.

Question 5

An inspector notes water ponding on a newly placed asphalt surface. This most likely indicates:

Accepted Answer

Inadequate cross-slope or improper surface elevation

Answer

Ponding water on pavement indicates that the surface lacks the required cross-slope or has low areas due to grade control errors.
