Why We Built THOOM: The Plan Check Problem Nobody Talks About
David ThulFounder, Woden Tech·April 15, 2026
The Plan Check Problem
Every fire protection engineer knows the drill. You submit plans. The AHJ sends back comments. You manually extract each one, figure out which code section applies, draft a response, and pray nothing falls through the cracks.
The Numbers
The typical plan check cycle burns 30-40% of total project time. Not on engineering. Not on problem-solving. On iteration management.
What THOOM Does Differently
THOOM doesn't replace the engineer. It handles the mechanical parts of plan check management so engineers can focus on the work that actually requires their expertise.
- Automatic extraction from any AHJ PDF format
- Code-cited drafts scoped to your jurisdiction
- Full audit trail from extraction to approval
- Zero manual entries to start a project
The engineer stays in the loop. The paperwork doesn't.
