1.3 ABBREVIATIONS AND DEFINITIONS
A. Damp Location (Interior): A location that is normally or periodically subject to condensation of moisture in, on, or adjacent to surfaces.

B. Dry Location (Interior): A location not normally subject to dampness but which may subject to temporary dampness provided ventilation is adequate to prevent an accumulation of moisture.

C. Mezzanine: An intermediate floor structure between the floor and ceiling of any story within a building, not exceeding one-third of the floor area of the room in which it is located, and which has not less than seven feet of clear height above and below the intermediate structure. A mezzanine does not contribute to the building area in an area calculation and is not considered a building story. However, the area of a mezzanine is included in the fire area calculation of a building.

D. Fabricated Mezzanine: An engineered modular mezzanine consisting of fabricated components that require limited on-site assembly labor.

E. HSLA: High-strength low-alloy steel.

F. Wet Location (Interior): A location in which water or other liquid frequently drips, splashes, or flows onto or against a surface and adequate drying does not occur.

1.4 SYSTEM DESCRIPTION
A. Engineered, prefabricated, moment-resistant, bi-directional rigid frame mezzanine assembly with decks, stairs, railings, and other necessary appurtenances for complete construction complying with requirements of authorities having jurisdiction.
