Key Capabilities

🔍

5 Detection Protocols

Protocol-based detection for All elements, Structural vs MEP, Architecture vs MEP, Windows & Doors vs MEP, and MEP Internal — ensuring thorough multi-discipline coordination.

🗄️

Dual Storage System

Clash data stored in both Revit Extensible Storage and a persistent JSON database, enabling history tracking, recreation, and team synchronization across sessions.

🤖

AI-Ready Interfaces

Each workflow exposes structured tool interfaces for chatbot and AI agent integration — enabling natural language commands to trigger clash detection and management.

📚

Multi-Building Support

Independent clash tracking per building within a multi-building project, with global and local clash IDs for granular reporting.

🌿

Revit 2021–2026

Full support across 6 Revit versions from a single shared codebase, using conditional compilation symbols for version-specific API differences.

✅

Clash Reviewer & Schedule

Browse, filter, and navigate clashes by status (Open, InProgress, Closed, Ignored), generate clash schedules, and track resolution progress over time.
