As Built Documentation

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.

Quick Start

# Register document
doc = manager.register_document(

    title="Floor Plan Level 1",
    document_type=DocumentType.DRAWING,
    discipline="Architectural",
    original_file="drawings/A-101.pdf"
)

# Add field markup
markup = manager.add_markup(
    doc.document_id,
    description="Wall moved 6 inches south",
    location="Grid B-3",
    marked_by="Site Superintendent"
)

# Upload as-built
manager.upload_as_built(doc.document_id, "as-built/A-101-AB.pdf", "AB")

# Verify
manager.verify_document(doc.document_id, "Project Manager")

# Check completeness
report = manager.get_completeness_report()
print(f"Completion: {report['completion_percent']}%")
