CTQP Quality Control (QC) Manager

Question 1

What is the primary distinction between Quality Control (QC) and Quality Assurance (QA) on FDOT construction projects?

Accepted Answer

QC is the contractor's process for verifying their own work meets specs; QA is FDOT's independent verification that the QC process is working

Answer

QC is the contractor's internal process — they test, inspect, and correct their own work. QA is FDOT's independent oversight to verify that the contractor's QC is functioning effectively and that the finished product meets specifications. Both roles have distinct responsibilities and cannot be combined.

Question 2

Under FDOT's Contractor Quality Control program, who bears primary responsibility for developing and implementing the Quality Control Plan on a construction project?

Accepted Answer

The Contractor's designated QC Manager

Answer

The Contractor is responsible for quality control of their own work. The Contractor's designated QC Manager develops the QC Plan, oversees its implementation, and ensures all work and materials meet contract specifications. FDOT performs Quality Assurance (QA) as a check on the contractor's QC process.

Question 3

A Non-Conformance Report (NCR) is required when:

Accepted Answer

Work or materials fail to meet contract specification requirements

Answer

An NCR documents any instance where completed work, tested materials, or construction processes do not conform to the contract specifications. The NCR initiates a formal corrective action process, including root cause analysis and disposition of the non-conforming item.

Question 4

In a Quality Control Plan, a 'hold point' is defined as:

Accepted Answer

A mandatory stopping point in a work sequence where work cannot proceed until inspection or approval is obtained

Answer

Hold points are critical junctures in the construction process where work must not advance until a specific inspection, test, or approval step has been completed and documented. Unlike witness points (which notify but do not stop work), hold points are mandatory stops.

Question 5

When a QC test result fails to meet specification requirements, what is the FIRST action the QC Manager should take?

Accepted Answer

Document the non-conformance and initiate a corrective action investigation to determine the root cause

Answer

Upon a failing result, the QC Manager must first document the non-conformance formally and investigate the root cause before any disposition decision is made. Premature removal or work stoppage without investigation may be unnecessary if retest data, mix design review, or equipment calibration check reveals the initial result was an outlier.
