Free drawing audit

Send us your drawings. Get a RedMark Report back in 48 hours.

We'll scan your drawings, return a ranked list of coordination errors and documentation gaps, and show you — on your own project — exactly what your manual QA missed.

Or book a 20-min demo if you'd rather walk through it live.

Before you upload

What makes a good set to send.

RedMark is designed to work with a self-contained PDF drawing set — one project, with the drawings that reference each other included together.

Send the MEP set for one project

Ideally all of it. At minimum, try to include:

  • Mechanical plans
  • Mechanical equipment schedules
  • Electrical power plans
  • Electrical panel schedules

Why completeness matters

Most of what RedMark catches lives between documents, not on any single sheet:

  • Equipment on a plan that never made it to the schedule
  • A breaker size that doesn't match the unit it serves
  • A keyed note with nowhere to land

Each of those needs both sides present. A plan without its schedule can still be read — but there's nothing to check it against.

How it works

Three steps. 48 hours.

We scan

Our engine reads every sheet. Only minimal, context-free metadata reaches an LLM — never your drawings.

Where it's running

Tested on live projects, not demo sets.

Shipping cadence
New checks weekly
v1 shipped March 2026. The check library grows every week, driven by what engineers in the field ask for.
Live proof-of-concept · London
37 storeys
Running QA on the mechanical package of a major London commercial tower — fire dampers, smoke control, congested basement coordination.
Engineering-rule checks
Calculated, not guessed
RedMark recalculates values from first principles — heater sizes from airflow and ΔT, MOCP against panel schedules — and flags numbers that don't compute.
Frequently asked

Five questions.

Is there a catch?

No. We email you the report and offer a 20-minute walkthrough. You can ignore the walkthrough — we'll still send the report. The audit is the wedge, not the upsell.

What if my sheets are sensitive?

Your drawings, title blocks and company names are never sent to an LLM — only minimal, context-free metadata. We can also delete drawings after the audit is delivered. See the full security model.

What format do you need?

PDF. Single sheets or multi-sheet sets. No CAD or Revit files required.

How much should we send?

The MEP set for one project — the more complete, the more we find. If the file is large or you would rather send it another way, email sales@redmark.ai and we'll arrange it.

How long does it really take?

48 hours, business days. Many reports go out faster.

Ready?

Send us your own sheets.

We'll do the rest. 48 hours, free, no obligation. Or book a demo if you'd rather walk through it live.
