How should a construction quality manager handle design change requests (DCRs) that propose enhancements outside the original project scope?

A Design Change Request (DCR) is a formal proposal to modify project specifications. While

enhancements can improve design outcomes, each DCR must be evaluated for its impact on quality,

cost, and schedule before approval.

The best approach is to evaluate DCRs systematically (Option C) by:

Assessing compliance with project requirements, quality standards, and codes.

Identifying quality risks and ensuring the proposed changes maintain structural integrity.

Conducting impact analysis on cost, schedule, and constructability.

Coordinating with relevant stakeholders (owners, engineers, and contractors) to verify feasibility.

Why Other Options Are Incorrect:

Option A (Approving all DCRs based on team preference): Can lead to scope creep, delays, and

budget overruns.

Option B (Rejecting DCRs outright): Ignores potential improvements that could enhance project

quality and efficiency.

Option D (Allowing the design team alone to decide): Lacks multidisciplinary review and can

overlook broader project constraints.

According to DOE G 413.3-1 and ISO 9001:2015, systematic evaluation of DCRs is essential for

maintaining quality and project success​.

Thus, the best answer is C: Evaluate the DCRs to ensure quality checks are identified.
