As-Built Documentation Manager

Business Case

Problem Statement

As-built documentation is often incomplete:

• Field changes not documented
• Drawings not updated consistently
• Missing documentation at closeout
• Difficult to verify completeness

Solution

Systematic as-built documentation tracking with drawing markup management, completeness verification, and handover preparation.
