Provide indoor swimming pool and whirl pool as a minimum, unless Facilities Program dictates otherwise.
• Contiguous indoor/outdoor swimming pools may be considered in seasonal locations.
• Larger facilities may require separate pools, especially where the outdoor pool is the center of a resort environment.

Pool Designs: Mechanical and structural engineers or a qualified swimming pool design / build contractor develops the swimming pool mechanical operation and structural design.
• Standards: Comply with governing mechanical, structural and sanitation codes and design pools for local conditions such as climate and soils.
• Accessibility: Design pools for use by guests with disability. Provide a transfer lift at each pool.
• Safety: Safety is of prime importance in design of pools and associated areas.
• Signage: Provide regulatory / safety and “No Diving” signage.
• Pool Entry: Primary access point for guest arrival at pool typically toward shallow end of pool.
• Structure: Concrete structure with pool plaster or tile.
• Configure primary swimming pool to facilitate simultaneous usage by lap swimmers and recreational bathing.
+ Water Surface Area: 140 m2 (1,500 sq. ft.) minimum.
+ Minimum Pool Depth: 1.0 m (3'-4")
+ Maximum Pool Depth: 1.5 m (5 ft.)
+ Maximum Slope of Pool Bottom: 1 to 10
• Diving is prohibited.
• Minimum Pool Depth Area: Approximately 15 to 20 percent of the total pool area.
• Shallow Area: Set visually apart from remaining pool by means of removable floating lifeline or contrasting tiles from pool edges and extend across bottom.
• Pool Perimeters: Fully accessible for general maintenance and life saving / rescue purposes.
• Access: Include stair access with handrails at shallow end of pool with additional stairs or ladders every 23 m (75 ft.) around pool perimeter. Include railings on both sides of stairs.
• Steps: Make level changes obvious by providing 5 cm (2 inch) slip resistant edge, contrasting in color on vertical and horizontal nose of each pool step and bench or other means.
• Skimmer: Skim gutter and skimmer details are provided by the pool designer
• Skimmer Cover: Use skimmers for surface return water as opposed to a continuous scum gutter at the pool perimeter, except as required by code. Conceal skimmer lids with a pool deck paving cover designed to blend with the pool deck design.• Coping: Provide a coping band at the pool edge consistent with the project paving and hardscape materials pool coping compatible with the finish texture and material used for the slip resistant, pool deck paving.
• Acoustics (Interior Pool): Pool enclosure Reverberation Time (RT) 60 Max = 4 seconds.
• Deck Drains: Include continuous perimeter flush deck drains at inside edge of pool coping.
• Floor: Select floor tile with minimum coefficient of friction factor of 0.6 wet/dry.
• Accessories: Slides, swimming tunnels and bridges are prohibited unless reviewed
Loss Prevention.
• Lighting: Provide underwater lights at 3 m (10 ft.) intervals. Provide lights with residual current, circuit protected and on emergency circuiting

Whirl Pool: Heated whirl pool is 3 m (10 ft) diameter minimum.
• Location: Typically, locate in close proximity to deep end of Swimming Pool. Contain within restricted adult only areas.
• Equipment: Locate whirl pool mechanical equipment in a designated, programmed room unless otherwise approved by the Owner and Marriott.
• Pool Heating: Include heating equipment to maintain 40o C (104o F.) water temperature with an in-line thermometer graded in 2-degree intervals installed in the Filter Room between the liner and heater.
• Slip Resistance Factor: 0.6 dry/wet for decks, copings, benches, and pool floors.
• Pumps: Provide multiple pumps, or pumps with two speed motors, with a low range, for normal recirculation to maintain pool temperature and filtration, and a high range for increased water jet action during whirl pool use.
• Drains: Include 2-drain inlets to drain (suction) line with securable grate to avoid suction trapping.
Design

• Provide chrome plated, non-corrosive metal or bronze plumbing fittings and nozzles if exposed to guest view.
• Air Injector: Installed for jet action during whirl pool use.
• Timer Control Switch: Provide a guest accessible 15 minute timer control switch to activate the whirl pool’s pumps and air injector. Locate the control out of reach of bathers in the whirl pool and within reach limits of governing accessibility codes. • Emergency Stop Control: Provide an emergency stop
button to deactivate the whirl pool jet circulation, pumps and air injector. Locate adjacent to timer control.
• Signs: Include regulatory and safety signage.
