600 Administration Building

These buildings are designed for the administrative office functions for a school plant or board. The interior finish may have plaster or drywall and, depending on the quality, utilize paneling and special wall covering. The better facilities will have good meeting rooms and private offices.

Floor finishes are carpet, terrazzo or vinyl. Ceiling finishes vary with the quality. Luminous ceilings and high intensity fluorescent lighting are found in the better qualities.

In the restrooms, both the number and quality of fixtures generally correspond to the quality of the building. Typically, the restroom areas have ceramic tile floor finish. At all quality levels, metal partitions and commercial plumbing fixtures can be found.

Most offices have a combined heating and cooling system.
