mgoodman60 Drawing Control Skill — Foreman OS
Overview
The drawing-control skill is the central nervous system for managing construction drawings in Foreman OS. It tracks every revision, incorporates Architect/Engineer directives (ASIs), flags superseded sheets, and ensures the field works from the current set. Drawing management directly impacts quality, safety, cost, and schedule — this skill prevents costly rework by controlling the flow of information from the A/E to the field.
Core Responsibilities
- Revision Tracking: Maintain complete drawing log with revision history, dates, and change descriptions
- ASI Processing: Automatically update affected sheets when directives are received; flag superseded revisions
- Current Set Verification: Generate discipline-based reports of the latest drawing revision for every sheet
- Field Audit: Compare physical field sets against digital log; alert on out-of-date usage
- Distribution Control: Track which team members received which revision and when
- Change Summary: Extract revision cloud data and summarize deltas between revisions
- Integration Pipeline: Feed current drawing data to RFI prep, daily reports, submittals, and look-ahead planning
1. Drawing Log Data Model
The drawing-control skill stores all drawing metadata in a JSON schema. This provides a single source of truth for the project's drawing package.

2. ASI Processing Workflow
When the Architect or Engineer issues a Supplemental Instruction (ASI), the drawing-control skill manages the intake, revision updates, and distribution.
ASI Receipt & Processing Steps
- Receive ASI → Capture ASI number, date received, engineer/architect name
- Identify Affected Sheets → Parse ASI document to extract sheet numbers impacted
- Update Revision Numbers → Increment revision (Rev 0 → Rev 1, etc.) for each affected sheet
- Mark Superseded → Flag previous revisions as superseded with ASI reference
- Extract Change Summary → If revision clouds are present, summarize deltas
- Cross-Reference ASI Log → Update project-config.json ASI table with drawing link
- Generate Distribution Notice → List which sheets changed and who needs new copies
- Queue Automatic Re-distribution → Trigger notifications to field team
ASI Tracking Table Template
| ASI # | Date Received | Issued By | Sheets Affected | Description | Status | Distribution Complete | Notes |
|-------|---------------|-----------|-----------------|-------------|--------|------------------------|-------|
| ASI-001 | 2026-01-15 | Smith Architects | A-101, A-102, A-103 | Floor plan revisions for door swing conflicts | Distributed | 2026-01-16 | All field copies updated |
| ASI-002 | 2026-02-05 | Yeiser Structural | S-201, S-202 | Anchor bolt layout modifications | Distributed | 2026-02-06 | Confirmed with steel sub |
| ASI-003 | 2026-02-18 | Davis HVAC | M-101, M-102 | Equipment substitution | Pending | - | Awaiting drawings from vendor |
ASI-to-Revision Mapping
When an ASI requires drawing revisions, the mapping below ensures consistency:
{
"asi_number": "ASI-001",
"date_received": "2026-01-15",
"drawings_affected": [
{
"sheet_number": "A-101",
"previous_revision": "Rev 0",
"new_revision": "Rev 1",
"description": "Door swing and furniture layout corrections"
},
{
"sheet_number": "A-102",
"previous_revision": "Rev 0",
"new_revision": "Rev 1",
"description": "Door swing and furniture layout corrections"
}
],
"distribution_initiated": "2026-01-16",
"distribution_complete": true
}
3. Current Set Verification
The drawing-control skill generates on-demand reports showing the latest revision of every sheet in the project.

4. Revision Cloud Summary
When new drawing revisions are received, the drawing-control skill extracts and summarizes revision cloud data (if available in PDFs).

"sheet_number": "A-101",
"comparison": {

}
}
5. Drawing Distribution Log
The drawing-control skill tracks who received which revision and when, providing accountability and re-distribution triggers.
Distribution Log Entry
{
"sheet_number": "A-101",
"revision": "Rev 1",
"distribution_round": 1,
"date_distributed": "2026-01-16",
"distribution_list": [
{
"recipient": "W Principles (Super - Miles Goodman)",
"role": "Super",
"method": "email",
"date_sent": "2026-01-16",
"email": "miles.goodman@wprinciples.com",
"confirmed_receipt": true,
"receipt_date": "2026-01-16"
},
{

"method": "email",
"date_sent": "2026-01-16",
"email": "office@stidhamcabinets.com",
"confirmed_receipt": true,
"receipt_date": "2026-01-17"
}
],
"re_distribution_required": false,
"notes": "ASI-001 revision; follow-up call made to EKD on 2026-01-17 to confirm receipt."
}
Automatic Re-distribution Triggers
The skill automatically initiates re-distribution when:
- New revision issued for a sheet already in circulation
- ASI affects multiple sheets in one directive
- Field reports reference superseded revision
- Submittal review flagged a drawing as outdated
6. As-Built Drawing Integration
When processing as-built or record drawings, the drawing-control skill connects revision tracking data to the closeout documentation pipeline. As-built markups must be reconciled against the current revision of every sheet before project closeout can be certified.
As-Built Data Source
Read plans-spatial.json → as_built_overlay
Per-Sheet As-Built Tracking
Track as-built markup status per sheet in drawing-log.json → as_built_status[]. For each drawing sheet, record the following fields:
| Field | Type | Description |
|---|---|---|
as_built_markup |
string | Status: none, in-progress, or complete |
deviations_count |
number | Total deviations from the issued-for-construction drawing |
markup_by |
string | Name of person who marked up the as-built |
markup_date |
ISO 8601 date | Date the as-built markup was completed |
reviewed_by |
string | Name of person who reviewed the as-built markup |
review_date |
ISO 8601 date | Date the review was completed |
Revision Cross-Reference
Cross-reference as-built deviations against the current revision of each sheet — deviations should reference the latest revision number. If a sheet has been revised via ASI since the last as-built markup, the markup must be re-verified against the new revision before it can be marked complete.
Deviation Cause Linkage
Link deviation causes to upstream change documentation:
- RFI-directed changes →
rfi-log.json(deviations that resulted from RFI responses or field clarifications) - CO-directed changes →
change-order-log.json(deviations that resulted from approved change orders)
This linkage ensures every as-built deviation is traceable to its authorization source.
Closeout Completeness Check
Flag sheets where as-built markup is still none or in-progress as closeout-incomplete. These sheets must be resolved before the drawing package can be submitted for final owner acceptance. The /drawings status report should include an as-built completeness column during the closeout phase.
