What is a good guideline when evaluating art?

The artist, architect and engineer could work collaboratively to integrate the artist's ideas into the building/facility, or

Funds can be pooled for community-based public art projects, and

The architect must work cooperatively with the artist and provide the artist, in a timely manner, with all necessary plans, blueprints, drawings, and other such materials that the artist deems necessary to his/her work.
