AI Design Reviews

Computer vision that reads the drawings, not just the text

Components, segments, geometry, dimensions, spatial relationships — the way a reviewer does.

It works from ordinary 2D PDFs, with no BIM model, metadata, or special export required.

Catches things a text-based AI structurally can't, like a pipe running through a column.

Four kinds of checks

Drawing health: missing tags and dimensions, sheet index mismatches, broken detail references.

2D clash detection: ceiling device clashes, pipes through columns, mismatched slab edges.

Omissions and logical rules: missing power to pumps, under-rated doors in fire-rated walls, electrical panels that disagree between the floor plan and the single-line diagram.

Spec-to-drawing checks.

Verified by construction experts

In-house experts review every AI output before it reaches the customer, confirming the issue is real and setting its severity.

It's included on every review, not a paid add-on.

It's the reason teams get a short list of meaningful issues instead of a thousand indiscriminate flags.

Diffs

Visual change detection

Compares each new revision against the previous one.

Color-codes the result: green for added, red for removed, yellow for modified.

A reviewer intuitively sees the types of changes at a glance.

Similarity scoring

Scores each drawing pair by how much has changed.

Teams know exactly which sheets need attention, and can skip the ones that didn't move.

Change narrative generation

Describes each change in plain words — "doors shifted 2 ft east," "pump added to mechanical room," "door hardware spec changed" — so reviewers don't have to interpret the overlay themselves.

Custom Checks

Your checklist, codified as AI agents

Hand over your QA/QC manual, design issuance checklist, or internal standard and Buildcheck converts each line item into a check the AI runs. No prompt writing, no configuration — our team builds it with you as part of onboarding.

Runs inside the same review

Your custom checks run alongside the 500+ standard checks — on the same drawings, with the same severity scale and the same expert verification. Findings land in one issue list, not a separate report your team has to reconcile.

One standard across every project

Codified once centrally, applied identically on every project, team, and region — so review quality doesn't depend on who happens to be staffed. Senior expertise becomes a company asset instead of a personal one, and every check run adds to a growing dataset you can draw insights from across your entire portfolio.
