Frame Construction Material (declared and predicted) in lending decisions.

Frame Construction Material (declared and predicted) gives the primary frame construction material, declared and modelled kept separate, published modelled with 99.94% coverage across England and 97.21% across Northern Ireland. Where modelled, it remains separate from declared evidence so you can validate it against your own reference records. Attribution and refresh period are in the dictionary.

Pretira publishes frame construction material (declared and predicted) modelled at 99.94% coverage across England, 97.21% across Northern Ireland, refreshed monthly, with declared and modelled kept separate.

// routing pattern
IF frame_construction_material_declared_and_predicted != "standard" -> route to physical val

The sample record returns brick, a standard construction; a non-standard frame is a classic case to route to someone on the doorstep.

16.2Where it bites
01

Construction-risk routing - non-standard frames off the AVM path.

02

Verification against valuer notes and the fact find.

03

Portfolio concentration views by construction type.

16.3Provenance

Declared from record evidence; predicted by a model and published separately so your evaluation can compare it with reference records.

Three questions on this field.

Both, as separate fields, so a rule can weight record evidence over a model prediction where it needs to.

Yes - non-standard construction is a common trigger to route off the AVM path to a physical valuation.

Compare it with a dated declared reference cohort and keep the confusion matrix, cohort and limitations together. A buyer-run evaluation shows whether it is suitable for your routing rule.
