Quality Control Procedures Flashcards

Benchmark panels in finishing trades (e.g., brickwork, plastering) are used to:

Answer: Set an agreed visual and dimensional standard that all subsequent work must match

A benchmark panel, agreed and signed off by the client or engineer, becomes the physical reference standard against which all subsequent work on the project is judged.

Which of the following is the BEST description of 'quality assurance' as opposed to 'quality control'?

Answer: Quality assurance focuses on preventing defects through planned processes; quality control detects defects through inspection

Quality assurance is the proactive, process-oriented approach to prevent defects, while quality control is the reactive detection of defects through inspection and testing.

The Construction (Design and Management) Regulations 2015 require that quality-related information is maintained in which document?

Answer: The health and safety file, which is handed to the client at project completion

CDM 2015 requires a health and safety file compiled by the principal designer and handed to the client, which includes as-built information relevant to future maintenance and safety.

Water pressure testing of a newly installed pipework system is an example of:

Answer: A commissioning test that verifies the completed installation meets the design performance requirement

Pressure testing at commissioning verifies that the installed system is leak-free and can sustain the design operating pressure before handover.

Photographic records taken at each stage of construction primarily serve to:

Answer: Document the condition and conformance of work before it is concealed, supporting quality and dispute resolution

Dated photographic records provide irrefutable evidence of what was constructed and its condition at each stage, invaluable for quality disputes and future maintenance.

What does 'statistical process control' (SPC) help a site manager identify?

Answer: Trends and variations in a process that may indicate it is moving out of control before defects occur

SPC uses data from ongoing measurements to identify trends indicating a process is drifting from targets, enabling corrective action before defects are produced.

At project handover, which document package should the contractor provide to demonstrate quality compliance throughout the project?

Answer: A quality dossier including signed-off ITPs, test certificates, non-conformance records, concessions, and as-built drawings

A complete quality dossier with all inspection records, test results, non-conformance dispositions, and as-built drawings provides the client with full evidence of quality compliance.
