Office Conversion Structural Feasibility Multi-Agent with AutoGen and Portia AI

Converting legacy office buildings into residential units hits severe architectural roadblocks such as floorplate depth and plumbing stack limits. Build a multi-agent architectural analysis system using AutoGen and Portia AI to evaluate floor plans and estimate conversion costs per square foot. Achieve less than 8% error in structural feasibility estimates.

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
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

feasibility_match

Checks correct classification of conversion feasibility.

Binary check

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

Dimension 2

cost_mape

Mean Absolute Percentage Error for estimated cost per square foot. • target: 0.08 • range: 0-1

Binary check

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