Find firestopping issues in your Revit model before you issue.
{{ altH1 }}
Firestop Check is a Revit add-in that checks every builders work opening in your model against a ruleset built for your project, so your team can fix firestopping details before they reach site.
Built for MEP drafting, BIM coordination, and firestopping review workflows.
01 · The problemFirestopping problems do not always look like clashes.
Your model can look coordinated and still contain details that will not work in the real world. Wrong clearances, missing requirements, unsupported arrangements, incorrect product assumptions, or details that do not match the manufacturer’s tested installation can all slip through normal model review.
Installation rules are buried across tables, diagrams, tested details, and technical documents.A clash-free model can still contain firestopping details that need review.Problems found after issue can mean drawing revisions, installation delays, and awkward conversations.Teams need a way to catch rules-based issues on every iteration, not only at formal review points.
By the time those problems are spotted on site, during QA, or by a specialist reviewer, they are slower, more expensive, and more awkward to fix.
02 · How it worksRun a Firestop Check before you issue.
Firestop Check reads every builders work opening in your model, works out which services pass through each one, and checks them against the rules built for your project, then reports back in Revit and as a PDF you can send on.
1
Run the check in Revit
The add-in works on the model your team is already in, whenever they want a check.
2
See what failed, and why
Every opening comes back as pass, fail, or needs review, with the rule that fired and the measurement behind it.
3
Fix it, then re-run
Resolve what needs resolving and run the check again to confirm. Do that as many times as you like before drawings go out.
03 · What you getPractical checks, built for drawing teams.
Designed for teams who work in Revit every day. It checks model conditions and turns them into practical issues your team can review.Catch copper running too close to combustible pipe, damper openings cut too small for the fire batt to fit, and openings sitting tighter together than the wall allows, all before drawings go out.We transcribe the tested details for the products specified on your project into rules, then check every opening against them, with the manufacturer requirement cited on each finding.Findings appear in Revit and export as a PDF, each one naming the opening, the rule, and the measurement.RVC-02-W118 · 218 mm, minimum 300 mmOnce your ruleset is built, the add-in sits in Revit and your team runs it whenever they need. No waiting for a specialist to look at every model iteration.Catch issues while they are still cheap and simple to fix, before installation, QA, or handover pressure makes everything harder.
04 · What it checksDesigned for the details that usually get missed.
Firestopping issues often sit in the awkward gap between design, coordination, manufacturer guidance, and installation. Firestop Check is built to help surface those issues earlier. Examples include:
Minimum separation between openings in the same wallOpening size against the tested detail for what passes through itWhat actually passes through each openingServices resolved to types from your own modelRequired clearances between services sharing an openingCombinations the tested detail does not supportOpenings with nothing modelled through them yetAnything that could not be checked, reported rather than passed
Your ruleset is built for your project, so the checks available depend on the products specified and the manufacturer details we transcribe. Every report states what it did and did not cover.
05 · The reportEvery fire-rated opening, documented.
Each run produces a record of every fire-rated builders work opening in the model, whether it passed or not. Each entry names the services passing through it, the rules applied, and the reason for the result. Your team sees it in Revit, and it exports as a PDF you can send on.

Coverage is stated, not implied
Every report ends with a note setting out exactly what was measured and what was not, so nobody has to guess how far the check went. Where the model does not give the add-in enough to work with, the report says so and flags the opening rather than passing it.
06 · Who it’s forMade for the people who actually issue the drawings.
Firestop Check is for MEP and BIM teams who need practical answers inside the design process, not another theoretical compliance document.
MEP Drafting Teams
Check firestopping details before drawings go out.
BIM Coordinators
Surface firestopping issues alongside your normal model review process.
MEP Managers
Give your team a repeatable way to catch issues earlier.
Contractors
Reduce avoidable rework and late-stage firestopping surprises.
07 · Getting startedHow we get you up and running.
Firestop Check is set up per project rather than sold off the shelf. The rules your team checks against are the ones that apply to your building and to the products specified for it, so there is a short setup before anyone runs anything.
Book a free consultationPricing is per project. We will give you a clear figure after the call.
1
Book a 30-minute call
Tell us about the project. We will show you what Firestop Check does and be straight with you about whether it fits.
2
Send us the model and the products
Your Revit model, plus the firestopping products specified for the project.
3
We build your project ruleset
We turn the tested details for those products into the rules your model gets checked against. Usually within a few days, and we will confirm the timing with you on the call.
4
Install the add-in and run checks
Your team installs the add-in for Revit and runs a check whenever they want one, as often as they like.
Check your next model before you issue.
Give your team a faster way to spot firestopping issues, fix them earlier, and issue drawings with more confidence. Book a 30-minute call and we will walk you through what Firestop Check finds in a model like yours.
Revit add-in that checks every builders work opening in your model against a ruleset built for your project, so your team can fix firestopping details before they reach site.
