392 Industrial Engineering Building

The exterior of an industrial engineering building is similar to that of occupancy 494 (Industrial Light Manufacturing). However, the interior has a larger amount of office area and finished space than the manufacturing occupancy while containing some manufacturing and assembly areas. The best structures approach good office buildings in cost, with many partitions, best lighting, elevators or escalators, and fine detail. If the design appears closer to office use than to industrial, use occupancy 344 (Office Building).

Better quality exteriors have high-cost features and ornamentation. Interiors at most qualities are plaster or drywall with fluorescent lighting and adequate plumbing for the personnel. The quality of the fixtures is commensurate with the quality of the structure.

The following are not included in the costs: Furnishings, power feeds and special utilities for manufacturing machinery.

Availability of Elevators by Area for this occupancy: Yes
