TrunkReview · Drawing Revision Agent

A bulletin dropped. Find out what changed instantly.

The moment a new drawing revision lands in your PMS, TrunkReview compares every sheet to the prior version, highlights every change, clouded or not, in an overlay and even writes the narrative for you. It’s powered by Cortex, the construction intelligence layer that understands the entire drawing, not just text in the title block or markups.

How top contractors are saving time with Trunk Tools

HITT
I had a situation where, through the use of TrunkReview, [we realized] there was an entire room added inside a mechanical room. Our drywall contractor sent us a change order, and I noticed that this was added. So I asked him: did you pick up the fact that you have a new small room with ceiling grid and tile? And they said: oh no, I didn't catch that, that wasn't clouded. Now we're removing risk from our partners. And admittedly, same with us — we're removing that risk from us.

It’s probably saved at least two hours off my day of going through drawings and reviewing them one by one. I’m able to see the difference between details from revisions and use this information to send out to all the trade partners I’m working with.

I like that it catches the non-clouded changes because those are the ones that always slip past.

Why TrunkReview

Addressing Real-World Challenges Faced by Project Teams

Challenge

Properly reviewing a new bulletin for changes takes hours of your time, if not days. Even thorough reviews can miss non-clouded changes. Often, you simply pass the drawings down to your trade partners to inform you about changes.

Solution

TrunkReview handles the first pass QA/QC when a new bulletin hits in just a few minutes after it’s uploaded to Procore or Autodesk. You get a visual overlay and the narrative of changes is already written for you. Quickly scan the changes detected and begin coordinating with trade partners immediately.

Challenge

Bulletins arrive from the design team with non-clouded changes and missing or low-quality narratives. This presents risks to your project budget and schedule if something slips through the cracks.

Solution

TrunkReview reduces the risk of missed changes and immediately analyzes what’s changed so you aren’t waiting on an already too busy PE or APM to get to it. You have documentation for clearer communication with the design team and owner and accelerate the change order process by giving your trade partners a head start.

Challenge

Review quality and process vary from project to project with the experience of the reviewers.

Solution

TrunkReview brings one standard to every review across the organization, ensuring your project teams proactively catch changes, mitigate risk, protect your margins, and delight your customer.

Challenge

Missed changes lead to rework and delays, increasing your costs and adding new disputes to resolve.

Solution

TrunkReview gives your business the tools to be proactive rather than reactive. Your reputation as a builder on top of all the details grows with owners and owner’s reps.
