495 Industrial Heavy Manufacturing

Buildings designed for heavy specialized manufacturing processes and power or utility service plants. There is an average amount of office or support space commensurate with the quality included, typically for heavy industrials, between 4 and 12 percent.

Heavy Industrials are characterized by their typically heavy frames, craneways, walls and floors. The structural support will greatly influence the cost and quality selection. Exterior finishes are thick masonry or concrete, or heavy gauge metal siding. The interiors, except for the office, stores or shop areas, usually have minimal interior partitions and are large open areas. Lighting may consist of many heavy-duty or spark-proof fixtures.

The costs include all the power leads to the building and industrial sewer and drainage lines, but do not include the following: Power panels, power wiring or industrial piping to the fixtures or equipment used in the manufacturing process, hoists, cranes or personnel lifts.
