Final answer:
In terms of AIA contracts, preparation for, and attendance at, public presentations are considered Additional services.
Step-by-step explanation:
Preparation for, and attendance at, public presentations count as Additional services according to B101. In the context of AIA (American Institute of Architects) contracts, Basic services typically include standard design and administrative duties, whereas Additional services are those not included within the basic scope of services and are provided when specifically required for a project. These can include things like making presentations to public or community groups during the design and construction phases.
