BGE Inspection & Quality Control 4

Question 1

When conducting an above-ground survey (AGS) of a gas distribution system, what parameter is primarily being measured?

Accepted Answer

Pipe-to-soil potential to assess cathodic protection effectiveness

Answer

Above-ground surveys measure pipe-to-soil potential (voltage) to evaluate whether cathodic protection is providing adequate corrosion protection.

Question 2

A BGE quality inspector is reviewing a contractor's material certifications. What is the inspector verifying?

Accepted Answer

That materials meet the specified grade, standard, and traceability requirements

Answer

Material certifications confirm that materials conform to required specifications (e.g., ASTM, ANSI) and provide traceability to the manufacturer and heat/lot number.

Question 3

During electric underground residential distribution (URD) cable installation, what is the purpose of mandrel testing the conduit before cable pull-in?

Accepted Answer

To verify the conduit is free of obstructions or deformation that could damage the cable

Answer

A mandrel (a rigid cylinder of defined diameter) is pulled through the conduit to confirm the bore is clear and undamaged before the expensive cable is installed.

Question 4

What is the key difference between a quality control (QC) inspection and a quality assurance (QA) audit in utility operations?

Accepted Answer

QC checks finished products; QA audits the processes and systems used to produce quality work

Answer

QC focuses on detecting defects in the actual work or product, while QA evaluates whether the overall processes and management systems are designed to prevent defects.

Question 5

A BGE inspector finds that a gas main was installed at a shallower depth than the minimum required cover. The area has been paved. What should be recorded in the inspection report?

Accepted Answer

A non-conformance report (NCR) with location, depth found, required depth, and corrective action required

Answer

A formal non-conformance report documents the specific deficiency with measured data, location, applicable standard violated, and required corrective action.
