Disaster mitigation feature of buildings or not?

[karitotp]

We are finding buildings with columns in their base, and to determine the properties of the building we need to confirm whether the columns at the base of the building have the function of mitigating disasters such as floods or not.

From the past phases of HP project, the disaster mitigation parts of buildings are not considered in the drawn box, so, if that type of structure in Dominica have the function of flooding mitigation, the labeling would be like following.

Is it correct to consider those structures as disaster mitigation parts and not include them in the labeling box?

Good Day to all. This is not a really a mitigation feature. We often build on pilllars to allow for future expansion by constructing a second residential unit on the ground floor.

Thank you for the clarification, @cw5711!

Then, if that is the case, the corresponding labeling for that type of buildings would be: "COMPLETENESS: INCOMPLETE" and the drawn box would include all the columns, as shown in the following example:

• http://54.198.158.223:8080/tasks/36/jobs/36?frame=12

• http://54.198.158.223:8080/tasks/40/jobs/40?frame=2

Does this make sense to you?

I'm actually not sure. These lower levels are often built long after the main house has been built, sometimes more than 10 years later or it never happens. Ground floor unit is essentially an optional future addition and not part of the blueprint for the house in most cases.

Hope this helps.

@cw5711, then, if those type of columns do not are disaster mitigation features neither is part of the blueprint for the building, we could say that those cases should be labeled as the images below, considering only the structure above the columns and labeling them as "Complete".

@srmsoumya, will this be ok for the ML models, or maybe it could generate some confusion with incomplete buildings?

[srmsoumya]

@karitotp I would go with what you are suggesting - consider the structure above the columns & label them as complete.
