The model is the index. Every source connected.
IFC, Speckle, BCF, IDS, COBie, Procore and your document library — one model, one question, every source. Click any element and see every linked row.
Element Inspector — click an element, see every linked BCF, RFI, COBie and cost row.
Clash & coordination — BCF native, tracked to resolution.
IDS & COBie — validate the model, score handover quality.
Built for coordination, compliance, and handover.
Six modules working from one connected data layer.
Element Inspector
Click any element in the 3D viewer and see every linked row from every source: BCF clashes, Procore RFIs, COBie entries, IDS validation results, cost actuals. One click. Every source.
Clash and coordination
BCF native. Filter, prioritise, and track coordination issues without leaving Bildstak. Every status change is logged to the audit trail.
IDS and COBie compliance
Validate model elements against IDS specifications. Score handover quality against COBie. Flag non-conformances by element, discipline, and floor level.
Specification tracker
Track specifications component by component across the head contract and all supply contracts. Flag where contracts disagree before the conflict becomes an RFI.
Submittal schedule generator
Back-calculate submit-by dates from your programme and agreed lead times. Regenerate when milestones move.
Handover and FM readiness
Score COBie coverage. Track which elements are missing manufacturer, warranty, and maintenance data. Produce a handover gap report in one question.
If buildingSMART maintains it, we support it.

Bring your IFC and BCF export. We will run the demo on your actual model.
Frequently asked questions
How does Bildstak work for vertical building and commercial towers?
Bildstak federates IFC/Speckle models, Autodesk APS, BCF coordination issues, RFIs, COBie, IDS and cost data for vertical building projects — connecting the 3D model to every commercial and coordination record, with the Element Inspector and handover scoring built in. 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 score COBie handover readiness?
Bildstak scores COBie handover readiness by checking each asset in the model against the required COBie data fields — type, component, space, system, spare parts — and returning a completion percentage by asset category, cited element by element, so gaps are visible before the handover gate.

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 much does Bildstak cost and how is it priced?
Bildstak is priced per project, with two tiers plus optional add-on modules, so cost is predictable for procurement. Pricing scales with the project rather than per-seat, and a tailored quote is available on request. Read the full answer →
