Assessment

Assessment

Systematic collection and analysis of data, evaluation and recommendations regarding the portions of an existing building which would be affected by its proposed use.

Evaluation

The process of determining the structural adequacy of the building or component fro ist intended use. Evaluation by its nature implies the use of personal and subjective judgement by those functioning in the capacity of experts.
