Section 675IAC20-5-12. Deck requirements

   (a) Deck work shall be designed and installed so as to include the quality of subbase, concrete mix design, reinforcing, joints, and finishes. Work performed in accordance with the American Concrete Institute (ACI) Standard 302.1R-04, "Guide for Concrete Floor and Slab Construction" may be deemed to comply with this requirement.

  (b) Decks, ramps, and similar surfaces, including step treads and coping, shall be slip-resistant and easily cleanable. The roughness or irregularity of the surfaces shall not cause injury or provide an abrasion during normal use. Depth markers, pool brand insignias, or similar special features located in or on the deck shall conform to this section.

  (c) Deck surfaces shall be provided at all perimeter areas of water attractions specified as entry or exit points.

  (d) Deck surfaces shall be of nontoxic, natural or man-made, impervious materials.

  (e) Steps for the deck outside the perimeter shall be in accordance with 675 IAC 13, the Indiana Building Code.

  (f) The unobstructed deck width provided around deck equipment, including:

(1) handrails;

(2) structural support columns;

(3) lifeguard chairs; and

(4) play equipment;

shall be a minimum of four (4) feet.

  (g) Water attractions with basins of five (5) feet of depth or more shall have an unobstructed, continuous deck with a minimum of three (3) feet in width.

  (h) The maximum slope of decks shall be one-half (1/2) inch per foot with a minimum slope of one-eighth (1/8) inch per foot. An exception is access ramps where the maximum slope shall be one (1) inch per foot.

  (i) The maximum width of voids between adjoining concrete slabs or between concrete slabs and expansion joint material, or both, shall be three-sixteenths (3/16) inch of horizontal clearance with a maximum difference in vertical elevation of one-fourth (1/4) inch. Any gap wider than three-sixteenths (3/16) inch shall be filled with suitable caulking material in accordance with the material supplier's specifications.

  (j) Joints, where the coping meets the concrete decks, shall be watertight.

(1) Where deck work joins the coping, the joining areas shall be designed and installed so as to adequately protect the basin and its mortar bed from damage.

(2) The area where pool decks join existing concrete work shall be protected by an expansion joint to protect the pool from the pressures of relative movements.

  (k) Control joints in concrete decks shall be provided to minimize the potential for cracks due to a change in elevations, separation of surfaces, or movement of the slab.

  (l) Decks shall be edged, provided with a radius, or otherwise relieved so as to prevent exposed sharp corners.

  (m) Decks shall be sloped to effectively drain either to perimeter areas or to deck drains. Drainage shall remove splash water, deck cleaning water, and rainwater. Site drainage shall be provided away from all decks so as to direct all perimeter deck drainage as well as general site drainage away from decks. Deck draining systems, when used, shall not drain more than four hundred (400) square feet to a single drain or twenty-five (25) feet of deck perpendicular to a continuous drain.

  (n) Open pit (leeching [sic] design) for backwash sump purposes shall be located so that it falls completely below adjacent deck work and fully outside a line projected forty-five (45) degrees downward and away from the deck work.

  (o) Circulation system piping, other than that integrally included in the manufacture of the water attraction, shall be subject to an induced static hydraulic pressure test (sealed system) at twenty-five (25) pounds per square inch for thirty (30) minutes. This test shall be performed before the deck is poured, and the pressure shall be maintained through the deck pour.

  (p) Valves installed in or under a deck shall be covered and readily accessible for operation, service, and maintenance.

  (q) All hose bibbs shall be fitted with vacuum breakers. At least one (1) hose bibb shall be provided in the equipment room. An additional hose bibb shall be provided in each toilet facility and at intervals along the deck so as to permit adequate cleaning using a maximum of one hundred (100) feet of hose. A hose bibb in the equipment room or dressing, shower, or toilet facility may be used for deck cleaning if located where a door opens directly to the deck and so that not more than one hundred (100) feet of hose, when laid across the deck surface, is needed to reach all areas of the deck.

  (r) Water powered devices, such as, but not limited to, water powered lifts, shall have a dedicated hose bibb. Hoses for water powered devices shall be so located so as not to create a tripping hazard.

  (s) Access to one (1) or more drinking fountains, installed in accordance with 675 IAC 16, the Indiana Plumbing Code, shall be provided within three hundred (300) feet of all water attractions.
