Challenge brief

What you are building

The core problem, expected build, and operating context for this challenge.

Extract asset attributes from IFC models using IfcOpenShell schema specifications to verify closeout readiness. Flag missing operations and maintenance attributes prior to FM system import.

Handover Commissioning Manager

Parse IFC model entities and extract facility equipment asset schedules.

Check manufacturer, serial number, and maintenance frequency against handover requirements.

Classify equipment missing warranty or operation records into non-conformance buckets.

Export audited asset register with approval recommendations for facilities management.

Browser data grid displaying IFC equipment tag status with compliance filter and CSV export.

Use open-access IFC4 architectural and MEP sample files from buildingSMART repository. Starter examples below are synthetic. They are not downloaded records.

IfcOpenShell Uses IfcOpenShell ecosystem tools ifcfm and ifccsv for extracting IFC data against FM handover requirements.

agno, pandas, fastapi. Agno provides lightweight agent orchestration to coordinate parsing and tabular asset reconciliation. Standard LLM with fast table reasoning and deterministic categorization capabilities.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Processes equipment instances from IFC schemas IFC2x3 and IFC4.

Identifies missing warranty expiration date and maintenance interval fields.

Produces structured reconciliation report with percentage readiness score.

```json [ { "input": { "model_version": "IFC4", "assets": [ { "guid": "2X$Y792", "name": "AHU-Roof-01", "ifc_type": "IfcAirHandlingUnit", "properties": { "Manufacturer": "VentCorp", "SerialNumber": "SN-98213", "WarrantyEnd": "2029-12-31", "MaintenanceIntervalMonths": 6 } } ] }, "expected_output": { "handover_status": "READY", "compliance_score": 1, "flagged_assets": [] } }, { "input": { "model_version": "IFC4", "assets": [ { "guid": "3Z#K114", "name": "PUMP-CHW-02", "ifc_type": "IfcPump", "properties": { "Manufacturer": "HydroFlow", "SerialNumber": null, "WarrantyEnd": null, "MaintenanceIntervalMonths": null } } ] }, "expected_output": { "handover_status": "ACTION_REQUIRED", "compliance_score": 0.25, "flagged_assets": [ { "guid": "3Z#K114", "missing_attributes": [ "SerialNumber", "WarrantyEnd", "MaintenanceIntervalMonths" ] } ] } } ] ```

Asset readiness logs are informational drafts; actual asset warranty activation remains subject to human signature. Use mock external writes. Require human review before any real deployment.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
4 scoring checks
Binary
1 pass or fail dimensions
Ordinal
3 scaled dimensions
Dimension 1

Complete workflow

Parse IFC model entities and extract facility equipment asset schedules. Check manufacturer, serial number, and maintenance frequency against handover requirements. Classify equipment missing warranty or operation records into non-conformance buckets. Export audited asset register with approval recommendations for facilities management.

Score scale
012
Score 0

Missing or incorrect.

Score 1

Partly complete, with documented gaps.

Score 2

Complete, with reproducible evidence.

Dimension 2

Correctness and evidence

Processes equipment instances from IFC schemas IFC2x3 and IFC4. Identifies missing warranty expiration date and maintenance interval fields. Produces structured reconciliation report with percentage readiness score.

Score scale

Dimension 4

Safe execution

Asset readiness logs are informational drafts; actual asset warranty activation remains subject to human signature.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
