D2010 PLUMBING FIXTURES

Provide quantity and type of plumbing fixtures required for the occupancy, use, and functions described for this facility.  Refer to Room Requirements Section for additional specific requirements for spaces with plumbing fixtures.  Provide handicapped fixtures in accordance with the referenced criteria in the Project Program.

NOTE: Coordinate with the Architect for the types of plumbing fixtures to be required in each area.  Expand description to include areas served by different fixture types where required.

NOTE:  Automatic controls for water closets, urinals, and faucets provide enhanced hygiene and improved water conservation but cost more and may require more maintenance than lever- or knob-operated valves.  This should be discussed with the user and automatic controls specified if requested by the user.

D201001 WATER CLOSETS

NOTE:  Flush valve toilets are normally provided in public restrooms.  Tank toilets are normally provided in Bachelor Enlisted Quarters (BEQs), Bachelor Officers Quarters (BOQs), and other private restrooms.  Wall-mounted toilets are preferred for ease of cleaning the restroom floor; floor-mounted toilets are more abuse-resistant.
