Roles in drawing quality assurance Within a project’s drawing set, which role is explicitly responsible for reviewing and verifying that drawings are free of errors before release?

Introduction / Context:
Quality in technical drawings is ensured by formal reviews. A specific role—separate from the original drafter—examines geometry, dimensions, tolerances, notes, and standards compliance to catch errors before release.

Given Data / Assumptions:

• Drawings must be verified for correctness and completeness.
• The reviewer should be independent of the drafter where practical.
• Organizations use sign-off workflows (drafter, checker, approver).

Concept / Approach:
The checker validates accuracy, standards adherence, and consistency with design intent. They verify dimension chains, tolerances, materials, references, and revision integrity, helping prevent costly downstream rework.

Step-by-Step Solution:
Identify the role tasked with pre-release error detection.Eliminate roles not involved in technical QA (client, receptionist, trainee).Select “Checker.”

Verification / Alternative check:
Release blocks commonly have signature lines for Drafter, Checker, and Approver/Engineer of Record, confirming the checker’s formal responsibility.

Why Other Options Are Wrong:

• Client: receives deliverables; not responsible for internal QA.
• CAD trainee: learning role; not accountable for final verification.
• Receptionist: administrative role; no technical review duties.

Common Pitfalls:
Skipping checking due to schedule pressure; relying solely on automated CAD tools without human review.

Final Answer:
Checker
