Testing and Quality Assurance Flashcards

Under IBC Chapter 17, which condition requires continuous special inspection rather than periodic special inspection?

Answer: Welding of moment frame connections

Welding of moment-resisting frame connections requires continuous special inspection because the inspector must be present throughout the entire welding operation.

What does an ICC-approved 'approved agency' mean in the context of special inspections?

Answer: An established and recognized agency regularly engaged in inspections with competent personnel

An approved agency is one with established competence and recognized status for conducting the specific inspections and tests required.

Under the IMC (International Mechanical Code), when must duct systems be tested for leakage?

Answer: When required by the energy code or when ducts are located outside conditioned space

Duct leakage testing is triggered by energy code requirements, particularly when ducts run through unconditioned spaces where leakage causes significant energy loss.

Which ASTM standard governs field testing of soils for compaction verification as referenced in ICC codes?

Answer: ASTM D1556 — Sand Cone or D6938 — Nuclear Gauge

Field density of compacted soils is measured using the sand cone method (ASTM D1556) or nuclear moisture-density gauge (ASTM D6938) to verify relative compaction.

Under the IPC (International Plumbing Code), what test is required to verify the integrity of a drainage, waste, and vent (DWV) system?

Answer: Air test at 5 psi or water test to the highest point for 15 minutes

IPC requires DWV systems to be tested with water to the highest point of the system or air at 5 psi, maintained for 15 minutes without leakage.

What is the role of the 'inspection record card' or job card required by the IBC during construction?

Answer: To be posted at the work site for recording required inspections as they are approved

The inspection record card must be posted at the construction site and serves as the official log for recording each required inspection approval.

When concrete strength test results fall below the specified compressive strength (f'c), what is the first course of action per IBC Chapter 19?

Answer: Conduct additional testing such as cores or load tests to evaluate actual in-place strength

IBC directs that when cylinder tests fall below f'c, the adequacy of the structure shall be evaluated by additional testing, including cores or structural analysis.
