The check
Design & coordination BIM coordination in the design team
The engineers deliver. The information requirements state which properties must be set. Between the two sits somebody clicking through models one by one — and ending up with an opinion, not evidence.
The same sample model as above, checked by the run the report further down also comes from. The colours show that run's result per element; nothing is staged.

1 · Scan
Every element it passes shows its result: green for passed, amber for a finding. Elements that only the “Unique GUIDs” rule checked stay pale — a pass like that says little, and that is how it is shown.
Load the model into project storage; each new revision becomes a version of its own.
Check it against your own rule set or the client's IDS.

Colour comes from 10 of the 14 published rules: 3 check the model as a whole, 1 finds the checked property on no element and therefore does not count as a pass.
Read the result per requirement: passed, missing, or wrong value.
3 · Handoff
The file opens in common BIM tools.
8 of the 10 marked elements are also in the BCF file. It carries the findings of the IDS check, not those of the rule check.
Hand the findings back to the authors as BCF 2.1.
The correction comes back as a new version — the old one stays traceable.
A check report with a pass rate per requirement, and a BCF 2.1 file that opens in common BIM tools. Not a “looks fine to me”.
Watch demo Evidence
The platform produced the document below itself, in one run over the sample model. Every figure comes from that run; the command at the end repeats it, and the files are there to download.

ConstructionSite management and subcontractors
The daily report gets written from memory in the evening, the defect hangs on the wall as a paper note — and the subcontractor who has to fix it has no account in your system.
Write the daily report — one entry per day, not two.
Request signatures, including from people without a user account.
The signature is bound to the document: it carries that document's SHA-256 checksum.
Sequential numbering in date order — no gaps, nothing filed retroactively.
Defect by QR code on the wall, response link to the subcontractor. If they report “Done” with a photo, the defect is set to resolved automatically.
A signed daily site report as a PDF whose signatures are bound to the checksum of that exact document — plus a running log of every signature event with time, IP address and device.
Watch demo The sticker on the wall opens the defect in the browser — no user account needed.
informed.build/m/… Whoever has to fix the defect gets a personal link. No account needed either.
informed.build/r/… Without at least one photo the response cannot be sent. “Delayed” also requires a reason.
A “Done” response sets the defect to resolved automatically, with the day of the response as its date. Not possible for days already locked by a final report.
Signature bound to the checksum
Before anyone signs, the daily site report is frozen as a PDF. Its SHA-256 checksum is computed server-side and attached to every signature. Change one character and the signature no longer fits — try it.
—bound to —Change a single character: the checksum changes completely and the signature no longer fits. Undo the change and it is valid again. The checksum is computed with JavaScript in your browser; nothing is sent.
This is a demonstration of the principle; signatures in the product are logged server-side.
Handover & acceptance
Client and project control
The difference between “checked” and “demonstrably checked” is the one you only notice once it is disputed.
Your own project role with read and approval rights, no administration rights by default. Whoever may approve may also write.
Read the check reports and BCF findings yourself instead of accepting assurances.
Version history per document: who, when, which revision.
Approval per version — server-side, bound to the approval right.
Signed daily site reports as part of the handover.
Evidence you can follow yourself — instead of a statement that checking took place.

Governance
Struck through: what we do not claim. With each, what holds instead. The list grows when we notice something, and shrinks when we have built something.
Not claimed: ISO 19650 certified
We are not ISO 19650 certified and do not enforce the approval status transition on the server.
Not claimed: Guaranteed availability and storage region
We do not commit to a storage region or to availability unless that is expressly agreed by contract.
Not claimed: Single sign-on, dedicated instance, on-premises
We have no single sign-on, no dedicated instance and no on-premises operation. The corresponding enterprise items are marked “on request” because they are to be agreed contractually and are not part of the product.
Not claimed: Gapless audit trail
Our audit trail is not gapless: changes to roles, memberships and billing, and downloads, are not captured.
Not claimed: Every geometric check exact
We do not claim every geometric check is exact: collision checking confirms hits triangle-accurately, but distance, containment and duplicate checks work on bounding volumes.
Not claimed: Reference customers
We have no reference customers to show. As soon as approved ones exist, they will be named here.
Not claimed: Every module ready for teams
Modules labelled “in development” store data locally in the browser. They are suitable for trying out, not for working as a team.
Not claimed: Processing limits in figures
We do not quote figures about processing limits that a code change could silently render false.
The governance page sets out roles, approvals, versioning, audit trail, data storage and export in detail — each split by what the server enforces and what only the application manages.
Go to the governance pageTools
The foundation under all three workflows — in the browser, nothing to install.
Open and analyse BIM models in the browser: navigate storeys, place section planes, measure distances, areas and angles.
Search, filter and edit all model data in a table — with virtual scrolling even for very large models. Save your changes back to project storage as a new IFC version.
Laser scans in LAS and LAZ straight in the browser — octree-based LOD rendering for large point clouds. As-built comparison against the BIM model in quality management.
Open drawings, calculations and documentation directly — with markups and comments, no download and no extra software.

FAQ
No. informed.build runs entirely in the browser — in Chrome, Edge and Firefox. There is nothing to install, no plugins and no updates to look after.
IFC 2x3 and IFC 4 for BIM models, LAS and LAZ for point clouds, BCF 2.1 for issues, DIN 276 and Uniclass for classification, plus PDF, DWG, DXF, XLSX, DOCX and images in the file viewer. We also read E57, but only to a limited degree today — for reliable results please convert point clouds to LAS or LAZ. GAEB import and export are implemented but not yet enabled.
The Free plan is free forever and includes the viewer with data table and classification for one project. On top of that you can try the Team features free for 14 days — no credit card. Storage and seats stay at Free level during the trial.
Local-first: your models are processed in the browser and cached locally. Once you place a model in project storage, the file and its prepared geometry and property data are additionally stored in the Cloudflare cloud — like every document in project storage. Access runs through a server-enforced permission system, changes to documents are logged, and shared links can be protected with an expiry date and a password. Our processors — Cloudflare, Clerk and Stripe — are named in the privacy notice.
We work ISO-19650-oriented: suitability codes, revision codes, container structure and the PIM/AIM breakdown are implemented. The status transition of an approval is currently managed in the application and not yet enforced on the server — which is why we say oriented rather than compliant. The governance page states exactly what is enforced.
In 30 minutes we show you the platform — with your own IFC models if you like. You ask questions, we show answers. Just fill in the form on this page.
Our roadmap is public, and the status labels on this page are the same ones. You can see at any time which modules are available, which run locally in the browser and what is still outstanding — and your feedback feeds straight into prioritisation.
Load your first IFC model into the browser for free — or have us show you the platform in a live demo.
