Keystone: openBIM ecosystem
1st place, That Open #TOP Founding Members Hackathon (results 13 October 2026).
One BEP, three buildings
Keystone runs on That Open Platform. One BIM Execution Plan (BEP, as ISO 19650 describes it), executed with Juan Hoyos’s dotBEP, drives the checks for three buildings with three purposes:
Snowdon Towers: new-build coordination. Clash detection and resolution with Revit, a carbon report traced to CO2data.fi factor ids, and the laser scan as a Gaussian splat beside the model.
Chania, Rivellino del Porto: heritage conservation. The present state and its reconstruction are checked with IDS and compared.
Farnsworth House: design iteration. A pool edited in the Pascal editor fails the BEP’s 3 m clearance, is moved, and is re-checked.
Checks run, people decide
Models travel as IFC, the BEP’s information requirements run as IDS checks, and every issue becomes a finding exported as BCF. Automations and Cloud Components do the checking; people decide.
The video and its credits
