REDLINE

Redline — Drawing Redlining

The process of marking engineering drawings to identify proposed, approved or field-verified changes pending formal revision.

Definition

Drawing Redlining is the controlled process of annotating engineering drawings with proposed, approved or field-verified modifications prior to incorporating those changes into the next controlled revision. Redlining provides a temporary record of engineering changes to support design review, construction, maintenance, commissioning and configuration management activities.

Why It Matters

Drawing Redlining records engineering changes pending incorporation into controlled engineering documentation.

In Practice

Drawing Redlining is commonly performed during construction, commissioning, maintenance and field inspections to ensure that engineering changes are accurately captured before controlled documents are updated.

Common Misuse

Drawing Redlining is the activity of recording engineering changes on drawings, whereas a Redline is the individual markup documenting a specific change.
