Columns
Each source column, with the name and type we use to store it.
2 of 37 columns carry a concept; 34 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.

If the original dates of construction are not included the designation report, the field is represented as 'Not determined'. | Not bound | Text | date_combo | text | — | |
build_type | BUILD_TYPE | The original type of building or structure as designed or built. If this information was not included in the designation report, is not known the field is represented as 'Not determined'. |
