## Input-limited parameters resolved against structural enums

- **ConstructionMethod** (structural_enums (p3)): CIS, PC, PT (Pre), PT (Post), PF, PPVC, Spun [for pile element only]

## Other input-limited parameters

These accept values from a defined list in the COP source table (not part of the global structural enums); see `examples` in `parameters.json`:

- SpaceName, AirTight, SelfClosing, VolumeControlled, EquipmentType
