SPECIFICATIONS for L'AIR BRAVO SUSPENDED FLOOR SYSTEM
for "Permanent" Theatre Installation intended for enhanced usage and durability

PART 1 - GENERAL

BRAVO is pre-fabricated, modular-integrated suspended floor system, with smooth, durable high-density surface, designed for permanent installation in multi-use theatres intended for dance, aerobics, martial arts, and other athletics. BRAVO is also designed for acoustic isolation installation. Modules install by tongue into groove method, module to module. Along with acoustic isolation, BRAVO is primarily designed to provide correct, consistent, and safe suspended flooring where greater panel strength and surface durability is required. BRAVO is designed for use with L'AIR DanceVinyl as performance surface for dance. BRAVO is delivered, as typical, with milled hardboard surfaces and is unsealed or unpainted. It is recommended to Paint the BRAVO surface, following installation, using SHERWIN-WILLIAMS KEM LUSTRAL, prepared and applied by manufacture's recommended method. 28 solid colors of Kem Lustral are available through Sherwin-Williams.

For "permanent" theatre installations, L'AIR furnishes suspended flooring, high-quality dance vinyls , doorway reducers, and vented vinyl cove molding.

1.1 DESCRIPTION

A. Concrete Sub-floor

Allow at least 31 days for new concrete to cure. Surface concrete shall be dry and free of grease, oil, or contaminating agents. Eliminate cracks, nails, and other protrusions. Vacuum and damp mop concrete sub-floor no less than 5 hours prior to installation. Concrete Sub-floor shall be smooth, on same elevation, and exhibit no greater deviation in elevation than 1/4" over a 12 ft. radius. If sub-floor requires leveling with compound, use only designed leveling compound applied at least 1/4" thick having point load capability of no less than 250 lbs per square foot static load. 2 layers of 10 mil or thicker plastic sheeting is to be used as moisture barrier in moist climates. Assess moisture content of slab prior to installation based on L'AIR specifications. L'AIR International is not responsible for site conditions inclusive of but not limited to sub-floor conditions or assessing sub-floor moisture levels. Sub-floor moisture levels are to be assessed and made available to L'AIR International no more nor less than 14 days prior to delivery of L'AIR materials. 

Below are the recommended maximum levels of moisture based on average conditions only. Installation conditions may vary; therefore, manufacturer accepts no liability for the following data:

cement / smooth	2.0 per cent or 3 lb. density
cement coating w/ pumice	3.0 per cent or 3 lb. density
cement/bitumen	2.0 per cent or 3 lb. density
anhydrite coating	0.5 per cent
plaster coating	0.7 per cent
magnesite coating	5.0 per cent

If sub-floor contains excessive alkaline salts, or moisture content of sub-floor is beyond limits specified , sub-floor must be vapor barrier sealed accordingly to achieve a continually dry sub-floor surface, free of contaminants. L'AIR accepts no responsibility for sub-floor conditions.

B. Wood Sub-floor

Surface of wood sub-floor shall be dry and free of dust, oil, grease, and cracks. Eliminate nails, splinters and other protrusions. Sub-floor shall be smooth, on same elevation, and exhibit no greater deviation in elevation than 1/4" over a 12 ft. radius. Use hardboard, plywood, or OSB to level sub-floor if necessary. Moisture content shall not exceed 7-10 per cent. Must be structurally sound with point loading capability of no less than 250 lbs per square foot. Built-up wood flooring shall have beams or sleepers on at least 16" centers, surfaced by no less than 1-1/2" of T&G composite sheeting such as plywood, plycore, OSB, or other sheeting products appropriate for conditions. Evidence of shift or instability in existing wood sub-floor, including but not limited to separation of floor boards, excessive or inconsistent spaces between wood sub-floor and walls, buckling or warpage, requires upgrading or replacement of sub-floor prior to installation of BRAVO.

C. Steel Sub-floor

Surface of steel sub-floor shall be dry and free of dust, oil, and grease. Eliminate burrs, slag, cracks, and any protrusions prior to installation. Sub-floor shall be smooth, on same elevation, and exhibit no greater deviation in elevation than 1/4" over a 12ft. radius. Must be structurally sound with point loading capacity of no less than 250 lbs. per square foot.

D. Ballet Barres - Remove existing floor-mounted ballet barres prior to installation of Excelle II Floor System. Modify specific modules located under ballet barres according to manufacturer's written installation instructions, and install within system. Re-install ballet barres onto modified floor modules.

A. General

IF INSTALLATION IS NOT BEING CONDUCTED BY L'AIR INTERNATIONAL, customer is responsible for off-load and installation labor. L'AIR BRAVO Suspended Floor System™, including specified transition ramps, cove molding, installation kits s, instructions, and any other installation accessories are palletized flat. Pallets loaded to maximum capacity are approximately 96" length by 48" width by, maximum, 72" height, and weigh up to approximately 3,000 lbs. Pallets are pallet jack and fork-lift compatible from ends or sides. Pallets contain spacers between modules to prevent crushing of suspension towers during shipping or acclimatizing storage at site. Spacers must immediately be replaced if hand off-loading onto pallets. See below for greater detail

UNLESS L'AIR INTERNATIONAL IS CONDUCTING INSTALLATION, manufacturer is not responsible for damage resulting from shipping or off-load.

B. Domestic

IF L'AIR INTERNATIONAL IS NOT CONDUCTING INSTALLATION, L'AIR BRAVO Suspended Floor System™ is typically delivered to designated destination by 75' - 85' tractor trailer. Handling: Flooring is, typically, not to be off-loaded to other equipment prior to site delivery. Pallets require up to 3,000 lb capacity forklift or pallet jack from ground or dock. L'AIR BRAVO Suspended Floor System™ should be off-loaded by pallet jacks and forklift. BRAVO System can be off-loaded by hand. Use caution, handle carefully to not damage product, and replace white Styrofoam packing spacers between modules, as spaced by manufacturer, if material is to be palletized and moved to site or stored for any length of time. 2 hours are allowed for site off-load. Following 2 hours, client may be charged for down time by shipper. UNLESS L'AIR INTERNATIONAL IS CONDUCTING INSTALLATION, L'AIR has no responsibility nor control of materials once materials have departed L'AIR docks.

C. International

L'AIR BRAVO Suspended Floor System™ is delivered to destination custom packed inside 40' or 20' sea containers, typically. Client or client's agent is responsible for custom tariffs, duties, and other national charges. See "Handling" specifications in B., above.
