For VDC and BIM Managers

Every coordination issue, with its full context attached.

You run the federated model and the clash process. Bildstak keeps every BCF issue, IDS check, and COBie property joined to the element it belongs to, so nothing gets lost between exports.

The model is federated. The information around it is not.

01

Issues lose their thread

A clash gets logged in one tool, discussed in another, and resolved in a third. By the next coordination meeting, half the context is gone.

02

Exports drift apart

BCF, IDS, and COBie each leave the authoring tool on their own schedule. Reconciling them by hand is a weekly tax on your time.

03

Every platform speaks its own dialect

Speckle, APS, and your CDE each name the same element differently. Tracking one component across all of them is manual work.

What Bildstak gives you

Element Inspector

Select any element and see every BCF issue, IDS requirement, and COBie property joined to it. One element, its whole history.

Federation engine

Standards kept honest

IDS checks run against the live model, so you see what passes and what fails before the deliverable goes out.

BIM, BCF, IDS, COBie

Speckle and APS, native

Connect your model platforms directly. Bildstak reads them as they are, with no extra export step in your week.

Integrations

Coordination issues that never lose context again.

Open the clash list and every row carries its discipline, its element, and its current status. Click through to the element in the 3D viewer and the BCF thread, the IDS result, and the COBie data are all there. The next coordination meeting starts with answers, not with a search.

What changes for your team

Coordination meetings get shorter

Context is already attached, so the room spends its time deciding, not reconstructing.

Deliverables go out clean

IDS results are visible before the export, so checks happen on your schedule rather than the client's.

One source of truth for the model

Every platform feeds the same federated view, so the team stops debating which file is current.

Frequently asked questions

How does Bildstak help BIM managers?

Bildstak gives BIM managers a live, queryable model that joins every IFC element to its BCF issues, RFIs, COBie properties and IDS compliance state — all in one place. Click any element in the 3D viewer to see every linked record, flag standard violations and track handover readiness without leaving the platform. Read the full answer →

What is the Element Inspector?

The Element Inspector is Bildstak's click-to-query interface for the 3D model. Click any BIM element and Bildstak shows every record linked to it — BCF issues, RFIs, COBie properties, cost lines and schedule activities — joined automatically by the element's IFC GlobalID. Read the full answer →

How do I check BIM clash status with Bildstak?

Bildstak checks BIM clash status by reading your BCF coordination issues alongside the IFC model, joining each clash to the element it references — so you can query open, resolved and overdue clashes by discipline, package or element type in plain English. Read the full answer →

How do I validate a model against IDS?

Bildstak validates a BIM model against an IDS (Information Delivery Specification) by checking each element's properties against the specification's requirements and returning a compliance report — flagging which elements pass, fail or have missing data — cited element by element. Read the full answer →

What is the difference between IFC and BCF?

IFC is the open file format that describes the building model itself — its elements and their properties. BCF (BIM Collaboration Format) is the companion format for the issues and comments raised against that model, such as clashes and design queries, each linked to specific elements.
