FROM UPLOAD TO RETURNED REVIEW

One connected workflow.

01

Build the review basis.

Add the design sources, specifications and submitted shop drawings.

02

Review with evidence.

Inspect AI findings, investigate pieces and annotate the working copy.

03

Return a clear decision.

Record the engineer’s review, export the package and track the next revision.

The engineer stays at the center.

AI surfaces potential discrepancies. Engineers verify the evidence and make the review decision.

A FEW DETAILS

Before you open
the next drawing.

Who is Trace built for?+

Structural engineers reviewing shop drawings during construction administration. Trace helps engineering teams compare submissions with project requirements, record review decisions and follow corrections across revisions.

What can I upload?+

PDF shop drawings and their applicable design sources, including structural drawings, schedules, typical details, specifications, bulletins and delegated design documents. Trace supports files up to 20 MB and 100 pages each, with a combined AI review limit of 25 MB and 60 pages.

Does Trace make the approval decision?+

The assigned engineer verifies findings and records a manual review decision. AI findings can be incomplete or incorrect. Trace does not calculate structural capacity, certify code compliance or independently approve fabrication.

Do I need to change my drawing software?+

Trace works in the browser with exported PDFs. Upload the selected drawings, compare them, add review markups and export a reviewed copy. Your original uploaded files remain separate.

How do I get started?+

Create your account, confirm your email, and open your private workspace. Add a project and upload its design sources and shop drawings to begin. If you already have an account, sign in.
