When the programme tightens, QA is the first thing to get cut short. RedMark reads the whole set either way — mechanical, electrical and P&ID, plans through to submittals — and returns a ranked list of coordination errors, missing keynotes, electrical inconsistencies and annotation issues, marked directly on the drawings.
PDFs, multi-sheet sets, schedules, legends, technical submittals. No CAD or BIM plugin required.
Inputs: PDF · DWG-exported PDF · schedule sheets · submittal packages
Custom OCR pipeline. Domain-trained CV on tens of thousands of M&E drawings. Reasoning layer with engineering rules.
Cross-checks: plan ↔ schedule · schedule ↔ submittal · mech ↔ elec
Provides an issues list and marked-up drawings. The issues list exports to Excel, and the drawings come back as PDFs with the markups on them.

Senior engineers don't sign drawings on the strength of a black-box AI decision. So RedMark doesn't ask them to.
For every check, RedMark builds a side-by-side view of the two sources it compared — the mechanical schedule against the panel schedule, the plan against the equipment list. You see what it saw.
Detected issues are highlighted in red. Equipment RedMark identified and matched successfully is highlighted in green. One glance tells you what needs your judgment and what has already cleared.
Deterministic logic does the reasoning, so every result traces back to a stated engineering rule. Your reviewer can confirm or overrule any flag in seconds — no trust required.
The comparison at the top of this page is exactly that view — RTU-1 matched on both schedules, MOCP flagged at 150 against 100.
A sample of the library below. Filter by discipline to see what RedMark catches on your sheets.
Every VAV, RTU, AHU, FPB and exhaust fan on the plan must appear in the equipment schedule — and every scheduled unit must appear on a plan.
Surfaces scheduled VAV airflow directly on the HVAC plan so connected airflow can be checked against the box’s rated capacity.
Confirms VAVs with electric or hot-water reheat carry the correct heater capacity — and that it is consistent across plans and schedules.
Cross-validates equipment schedules against contractor submittals and technical data sheets, line by line.
Flags keyed notes on the plan that are missing from the list — and notes on the list that appear nowhere on the drawing.
Catches panel schedule voltages and breaker sizes that don’t match the mechanical equipment they serve.
Every piece of mechanical equipment that needs power must appear on the electrical power plan. Misses here surface in the field as RFIs.
Verifies that calculated amperage demand on each panel stays below the panel’s rating.
Checks whether the manufacturer and model specified in the lighting schedule is still available to order.
Checks whether the manufacturer and model specified in the plumbing schedule is still available to order.
Every instrument tag on the P&ID must have a complete, matching entry in the instrument list.
Cross-references valve tags on the P&ID against the valve schedule and flags anything missing or extra.
Finds black text sitting on black linework — legible on your monitor, unreadable on a printed set in the field.
Flags two or more consecutive periods — the tell-tale sign of a callout nobody came back to finish.
Catches spelling errors while ignoring the abbreviations engineers actually use — VAV, RTU, AHU, FPB.
Matches hardware sets in the door schedule against the sets called out in the specification — flagging sets referenced but never specified, or specified but never used.

Request a checkFor MEP firms in steady production. One subscription for the firm, then a seat for each engineer who uses it — so the cost tracks adoption rather than headcount.
For global or large MEP firms with multi-office regional groups. Custom terms at volume.
No. Upload your drawings, get your report. No model to train, no integration to build, no IT lift. Most teams run their first project in under an hour.
Two parts — an annual base subscription for the firm, plus seats from $2,000 per engineer per year. A seat is any engineer running QA, and it doesn't have to be a dedicated QA role, so the cost tracks how many people actually use it. The base subscription and the seat rate are both confirmed at proposal. Enterprise terms are available for global or large multi-office firms.
No. RedMark is fully standalone — we accept your existing PDFs, schedules, and legends. Nothing to install, no CAD or BIM plugin, no change to how your engineers already work.
Yes. Encrypted at rest with AES-256, in transit with TLS 1.3. Only minimal, context-free metadata is sent to an LLM; your drawings, title blocks, company names and project details are never transmitted. Enterprise customers get contractual no-training guarantees. See our security model.
Yes. Submit through the platform or email your customer success contact and we'll come back with a target date.
Two paths — book a 20-minute demo, or upload 5 sheets and we'll return a free RedMark Report within 48 hours.
Upload 5 sheets from a recent project. We'll return a RedMark Report inside 48 hours showing exactly what your manual QA missed.
