CCI Structural Inspection Methods 2

Question 1

When inspecting a reinforced concrete beam, what is the primary concern regarding concrete cover over rebar?

Accepted Answer

Protection of steel from corrosion and fire exposure

Answer

Adequate concrete cover protects embedded steel reinforcement from corrosion due to moisture ingress and provides fire resistance.

Question 2

Which test is used to evaluate the in-place compressive strength of hardened concrete non-destructively?

Accepted Answer

Rebound hammer (Schmidt hammer) test

Answer

The rebound hammer test measures surface hardness of hardened concrete, which correlates to estimated compressive strength.

Question 3

During structural steel erection inspection, what does a 'plumb' check verify?

Accepted Answer

Vertical alignment of columns

Answer

A plumb check verifies that steel columns are perfectly vertical within allowable tolerances specified in the project documents.

Question 4

A construction inspector notices a crack pattern in a masonry wall that is diagonal and runs from a window corner downward. This most likely indicates:

Accepted Answer

Differential settlement of the foundation

Answer

Diagonal cracks emanating from openings such as windows are a classic indicator of differential foundation settlement.

Question 5

What is the purpose of a hydrostatic pressure test on a structural waterproofing membrane?

Accepted Answer

To verify the membrane resists water penetration under pressure

Answer

A hydrostatic pressure test confirms that the waterproofing membrane can resist water under sustained pressure without leaking.
