What we do

Subtillis checks drawing sheets against each other, the project specification, and project codes, fast. Findings connect to source context so reviewers can investigate, prioritize, and decide what needs to change without hunting through the set.

Why firms use it

Much of review time goes to mundane work: reconciling sheets, chasing references, finding missing details. Subtillis does that work quickly, so your team spends its time on design decisions, and fewer gaps turn into RFIs and rework during construction.

The kinds of issues we find

• Civil and plumbing plans that disagree on pipe sizes or elevations.
• Callouts that reference details that don’t exist.
• Room airflow that needs review against pressure requirements.
• Electrical schedules that reveal power or conductor sizing concerns.
• Missing landscape details and conflicting information across the set.

These categories come from customer reviews. Public examples use reconstructed drawings and illustrative values to protect firm and project identities.

How it fits into your practice

Start with your drawing PDFs and specifications. Establish the project requirements, run QA/QC, and review the findings with their sources. Your team resolves the design; AI review supports your process and does not certify completeness or code compliance.

Beyond QA/QC

Available workflows also include RFI response drafting, first-pass submittal review, and project chat. Document versioning, markup tools, and collaboration workflows are areas of ongoing development.
