Accuracy in error detection
The challenge
Plan review was fully manual. Officers cross-checked symbols, setbacks and area calculations by hand across hundreds of drawings, creating long approval queues and inconsistent decisions between reviewers.
Our approach
- 01 Built a detection model for architectural symbols and legends across varied drawing standards
- 02 Applied boundary segmentation to recognise plot outlines and setback margins
- 03 Automated area computation and rule validation against local building bylaws
- 04 Surfaced every flag in a reviewer UI with the source region highlighted for audit
The impact
Approval turnaround dropped by roughly 70% and error detection accuracy rose by 90%, with every automated decision traceable back to the region of the drawing that produced it.
