majiayu000 As-Built Documentation Tracker
Business Case
Problem Statement
As-built documentation challenges:
- Tracking hundreds of drawings
- Managing revisions
- Ensuring completeness
- Meeting handover deadlines
Solution
Systematic tracking of as-built documentation submissions, revisions, and approval status.

Quick Start
from datetime import date, timedelta
# Initialize tracker
tracker = AsBuiltTracker("Office Building A", handover_date=date(2024, 12, 31))
# Add documents
tracker.add_document(
document_number="A-001",
title="Floor Plans Level 1-5",
doc_type=DocumentType.ARCHITECTURAL,
discipline="Architecture",
contractor="ABC Architects"
)
tracker.add_document(
document_number="M-001",
title="HVAC Layout",
doc_type=DocumentType.MECHANICAL,
discipline="HVAC",
contractor="XYZ MEP"
)
# Record submission
tracker.record_submission("DOC-0001", revision="A", submitted_by="John Smith")
# Review
tracker.review_submission("DOC-0001", approved=True, reviewer="PM", comments="Approved")
Common Use Cases
1. Status Summary
summary = tracker.get_summary()
print(f"Completion: {summary['completion_rate']}%")
print(f"Overdue: {summary['overdue']}")
2. Contractor Report
status = tracker.get_contractor_status("ABC Architects")
print(f"Pending: {status['pending']}")
3. Forecast
forecast = tracker.forecast_completion()
print(f"On Track: {forecast['on_track']}")
