Broward County Roof Decks License(GITS©)

Roof Decks Category--Class "RD": The scope of work of a Class "RD" specialty building contractor shall include and be limited to the construction, fabrication, and installation of roof decks, which include and are limited to gypsum concrete decks, insulating concrete decks and fills, and structural cement-fiber roof decks.

(1) A gypsum concrete deck is a deck consisting of a steel reinforced mixture of gypsum, wood chips, shavings, or mineral aggregate and water poured on permanent forms that may or may not be supported by sub-purlins. Gypsum concrete weighs approximately thirty-five (35) to fifty-five (55) pounds per cubic foot (concrete--one hundred fifty (150) pounds per cubic foot), depending on the type of aggregate used. The steel sub-purlins (when used) are welded to the main framing and serve to support the formboards and anchor the deck to the main frame. The formboards are nonstructural and remain in place to provide a finished underside of the roof deck. Various types of formboards are available to provide light reflectance, fire resistance, insulation, or acoustical control. The reinforcing fabric used may be a galvanized wovenwire fabric.

(2) An insulating concrete deck and fill is a deck produced by mixing lightweight aggregates such as perlite or vermiculite with portland cement and water and placing, screening, and troweling as is done with conventional concrete decks. Lightweight decks may also be produced by "foaming" concrete with chemical agents. The cured deck may weigh between twenty (20) and forty (40) pounds per cubic foot, as compared to one hundred fifty (150) pounds per cubic foot for conventional concrete. The insulating properties and strength of the deck are controlled by the density and thickness of the lightweight concrete.

(3) A structural cement-fiber roof deck is a deck composed of treated wood fibers bonded together with portland cement or cementitious binders and compressed or molded into flat slabs. The slabs possess structural, insulating, and acoustical properties and are rated by Underwriters' Laboratories as "noncombustible." They are furnished as tongue-and-groove planks for application directly to steel bar joists or rabbeted for use on bulb-tee sub-purlins.

In order to be eligible to be certified as a Class "RD" specialty building contractor by the board, the applicant shall have at least two (2) years of practical experience in the category.
