Snagtwin is commissioning software built on the building model. Click an element in the IFC model and record against it: photographs, checklists, site observation reports and actions. The status of every element is reported from there, on the PC, on the phone and in the documents both of them produce.
Commissioning through BIM.

What Snagtwin is
Snagtwin reads the IFC models every discipline exports, from any authoring tool. Where the software has to decide, it measures the model and a person judges: nothing is tuned to one project's naming.
Snagtwin on the PC and Snagtwin Field on the phone work on one project: the same line items, photographs, site observation reports and drawings, with the phone working offline when the signal drops.
Site observation reports, weekly reports, action plans and document registers are generated from the same records, in PDF and Excel, under your company's letterhead and your client's logo.
How it works
Open the IFC models of every discipline as one federated view. Build the working tracker from a specialist's take-off, from a workbook or from the model's own families, with your stages and their statuses.
Click an element, or scan its QR label on site, and record against it: photographs, checklists, site observation reports and action items. Each record carries the element's tag, floor, room and model.
Status by stage, painted on the model and counted on the dashboard: charts, S-curves, the SOR register, inspection requests and documents, and the reports generated from them.
On the PC
Snagtwin opens the federated models of a whole building, keeps the working tracker beside them and puts each record where it belongs.
Each line item moves through your stages, and its status at each stage is one click in the tracker, the element card or the phone.
An SOR takes its element's details from the model and the tracker, so nobody types a tag, a floor or a room again.
Pick a floor and the equipment types to show: Snagtwin cuts the plan from the loaded models, with the rooms named from the model and every item tagged.
Replace a model with its next revision. Snagtwin matches the elements, places the new revision where the old one stood and asks only about the elements your tracker uses.
Play a tracker's SORs, actions or photographs stop by stop: the model travels to each element, with its photograph, comment and history beside it, for a review meeting or a walk-down.
On site
The phone app opens the same project as the PC: find a line item, photograph it, fill its checklist, raise an SOR or an action, and change its status, where the work is.
Keep a project on the phone with its drawings and photographs. Records wait in the outbox and are sent when the phone is back online.
A photograph filed on a line item is stamped with the line's QR code and the time it was taken, so it always leads back to its element.
An SOR raised on a phone is numbered by the project, never on the phone, so a number is never given twice.
Reports
Every report is the issuer's document: your logo at the top left, your client's at the top right, in portrait or landscape, as PDF, Excel or both.
| Report | What it holds |
|---|---|
| Site observation report | One SOR with its element, observation and numbered photographs |
| SOR report | The register with a thumbnail a row, then each SOR's card |
| Weekly report | The week's figures, charts and open items, for one tracker or all |
| Action plan | Actions with their owners, due dates and photographs |
| Documents | The register's status, ageing and charts |
Teams
A cloud project keeps the PCs and the phones of a team on one record. Each member signs in and works within their role.
