Dynamo Automation for 3D BIM Model Creation for Housing Corporation, Europe

The fast track approach used by the Hitech CADD Services leveraged Revit automation and resource ramp ups to achieve desired outcomes.

• Assessment of 2D drawings and property data of 300 building units received as input.
• A 3D BIM model was created of the first building as a prototype. This was accompanied by BOQs, façade views & floor plans.
• This BIM model was validated against prescribed reference parameters using customized Revit APIs. The validation:
  • Gave a go ahead to models with 100% equivalence
  • Asked for new versions to be created while preserving key modeling elements in case of 70% equivalence
  • Rejected models and asked for rebuilding them in case of 50% equivalence
• 300 BIM models were generated based on the validated initial model to create a comprehensive digital property inventory.
• The property GIS data was linked to each of the 300 BIM models.
• Customized Dynamo scripts automated repetitive tasks to speed up the process.
• Property data was extracted from the 300 BIM models using Dynamo features and imported into real-estate data sheets to be kept as digital inventory for online upload.
