AI Workflow for Automated Re-Submission and Revision Tracking

Reviewers spend hours visually comparing old and new plan sets to identify changes. This workflow automates that process using computer vision and drawing comparison algorithms to isolate modified elements—walls, fixtures, dimensions—instantly. The system generates a precise delta report, allowing reviewers to focus validation efforts only on what changed, not the entire resubmission.

By automatically verifying that all prior reviewer comments have been addressed in the new submission, the workflow prevents the common delay of a package being returned for missed items. It cross-references comment logs with the delta report, flagging unresolved issues. This ensures a complete resubmission, moving projects from 'revision' to 'approval' in a single cycle instead of multiple back-and-forths.

Uncaught discrepancies between revision sets can lead to construction-phase change orders, costing 5-20% of project value. This workflow creates an immutable, version-controlled audit trail of all changes, ensuring the approved permit set exactly matches the built design. By catching inconsistencies early, it protects project margin and prevents costly field corrections.

For municipalities, manual revision tracking is a major bottleneck, contributing to permit backlogs. Automating this step acts as a force multiplier, allowing a single reviewer to handle more resubmissions per week without sacrificing thoroughness. The system prepopulates review worksheets with change-focused comments, turning a multi-hour task into a 15-minute validation.

In disputes or liability cases, proving what was submitted and when is critical. This workflow automatically versions every submission, tags changes with timestamps and authors, and links them to specific reviewer comments. This creates a court-ready, defensible record of the entire revision history, strengthening legal and risk posture for all parties.

The workflow's value is realized through integration. It connects to project management platforms (Procore, Autodesk Build), document management systems, and municipal permit portals via API. This automates the entire flow: from revision upload, through delta analysis and comment closure, to final version archiving—eliminating manual data entry and ensuring system-of-record consistency.

The core component that ingests new and previous drawing sets (PDF, CAD, BIM) and uses computer vision and geometric algorithms to isolate modified elements. This replaces manual, error-prone visual diffing by reviewers, focusing their attention only on what has changed. Implementation involves integrating with document management systems like Autodesk Docs or Procore to automatically fetch version histories.

An orchestrated agent that cross-references the new submission against the previous review's comment log. It uses RAG over the comment database and document understanding to verify that each required change has been addressed, classifying items as 'resolved', 'partially resolved', or 'open'. This ensures no reviewer feedback falls through the cracks, preventing cyclical rework.

This component synthesizes outputs from the diff engine and verification agent into a structured 'delta report'. The report highlights changes, maps them to resolved comments, and flags new elements requiring fresh compliance checks. It includes intelligent routing logic to send the report to the appropriate discipline reviewer (e.g., structural changes to the structural engineer), integrating with municipal permit portals or project management tools.

Instead of triggering a full plan review, this orchestrator launches targeted compliance checks only on the modified building elements identified by the diff engine. It calls the relevant specialist agents (e.g., egress, structural, energy) with the specific delta data, dramatically reducing computational load and review time. This is where the major cycle-time savings are realized.

A critical control component that records every automated decision: which changes were detected, how comments were verified, and why certain re-checks were triggered. It produces a defensible audit log for municipal auditors, project managers, and legal teams, ensuring the automated workflow's decisions are transparent and accountable within regulated permitting environments.

The workflow's connective tissue that manages API connections to design software (Revit, ArchiCAD), permit tracking systems (Accela, CityView), and communication channels. It includes robust exception handling to route ambiguous changes, partial resolutions, or system failures to human-in-the-loop review queues, preventing the automation from stalling on edge cases.
