receptacle

Standard mounting heights for non-accessible lavatories, toilets and urinals

Indicate acceptable substrate and wet wall finish in the Notes box.

All plumbing must be on plumbing chase.

Consider sight lines from the entrance and between fixtures - avoid view of

urinals from entry/door, from other fixtures like lavatories, and avoid reflections

when possible

Accessible fixtures/clearances should not block path of travel or access to other

fixtures.

Do they ever ask for showers or ambulatory stalls in the restrooms?Do they ever ask for showers or ambulatory stalls in the restrooms?

Not in the restroom exercise. In space planning, you may have showers. For the

purposes of this exercise, neither an ambulatory stall or shower has been

required in the past 5 years.

The accessible stall must be fully accessible and not ambulatory.

In space planning you may have showers as part of the program, so is important

to know how these are drawn.

shows lavatories on wall that appears not to have a plumbing chase, this is

incorrect. Older versions may not accommodate a turning circle at entry.

Bobrick Planning Guide for Accessible Restrooms - to understand typical

layouts for restroom and space planning, but use the NCIDQ Building Codes,

especially regarding unobstructed turning circle. The turning circle should not

overlap a door swing or fixture on the exam.

Terminology

These aren't part of the Practicum per se, but learn and use the correct

terminology, something often misused in discussion.

or mounted in a counter (commercial) or vanity (residential)

sink - kitchen, bar, or lab sink

cabinet - a sink is mounted in a cabinet

vanity - residential lavatories are mounted in this

Use inches for dimensions, same as units as listed in NCIDQ Building Codes

Refer to program instructions for exactly what to dimensioned, codes to show is

accessible

Annotations & DimensionsUse the following annotation and dimension standards on yourdrawing and schedule.

Tag all fixtures and accessories per program, only 1 tag per same of each fixture

Note accessories as recessed, with no more than 4” projection into space

Templates

Qpractice recommends the ASID Washington State Templates especially for

restroom, but you can use any standard mass produced templates

Use 30" x 48" furniture shape or flip a 30” x 24” item like stove for clear floor

space

Mark most commonly used items with a Sharpie

Use wall mounted toilet symbol or omit the tank and pull sides back

Use urinal with elongated rim

Partitions

4-6” standard interior partitions

½” -1” stall toilet partitions - you must show thickness, a double line works

You can fur out, extend or add partitions to enclose or support lavatories or stalls

All plumbing must go on plumbing chase

Grab bars cannot go on toilet partitions, they require blocking within a standard

partition

Wet wall

Use cement board with porcelain or ceramic tile

Doors

4.5.2 ALL door openings shall be a MINIMUM of 36” [900 mm] wide with an 18”

[450 mm] clear space on the pull side of the door and a 12” [300 mm] clear space

on the push side of the door.

36” door gives a 34” opening

Use 36” accessible stall doors and restroom entry door

CAN use 34” in standard 36”W stall

Show push/pull clearances at accessible stall and restroom door if given (if not

given you do not need to add a door

Partitions & DoorsUse these standards for partitions and doors

Fixtures

Practice drawing these individual fixture components separately to build up your

hand drawing speed

Standard stall

Accessible stall with door swing in, version with door swing out

Urinal with accessible clear floor space

Toilets

Standard Stall

36” x 60” with 34” door - you should be able to fit this in all problems

30”W absolute minimum

Standard Toilet

15-18” centerline

Standard height 15”H to accommodate a range of people including children, and

differentiates from accessible toilet

Be sure to use the wall hung symbol on your template or omit the tank and pull

the sides back to the wall

Accessible Stall

5’ x 8’ with 60” turning circle, 36” door swings in, does not overlap turning circle

FixturesIncluding accessible and standard toilets, urinals, stalls, grab bars andlavatories

If less than 8’-0” then you may need to swing the door out when not in path of

travel

Dimension push and pull clearances

Must have 60” at rear wall and 56” at side wall

Toilet centerline at 16 - 18”, easiest to use 18” standard

Grab bars

Dimension both grab bars and distance from wall

Distance from wall is based on centerline of toilet, use 18" standard

Grab bar requires blocking, must be mounted on standard partition, not toilet

partition

Vertical grab bars

Vertical grab bars have not been listed as required in the NCIDQ Building Codes

in the 2015 and 2016 PDPs. In the 2015-2 PDP, the program requirements are as

listed in Part III C:

Grab bars, top of horizontal bar and centerline of vertical bar

but in Part II Program Requirements:

Grab bars as required by code.

The NCIDQ Building Codes accompanying 2015-2 did not require a vertical grab

bar.

This program instruction was not repeated in the 2016-1 PDP.

Vertical grab bars are NOT required in 2010 ADA Standards for Accessible

Design. See ADA 604.5 Grab Bars, and 605 Urinals.

While in IBC Chapter 11 Accessibility :

1101.2 Design. 1101.2 Design. Buildings and facilities shall be designed and constructed to beaccessible in accordance with this code and ICC A117.1.

ICC A117.1-2009 Accessible and Usable Buildings and Facilities requires an

additional vertical 18 inch bar located 39 to 41 inches (990 to 1040mm) off of the

back wall, and these may be required by state building codes, they are not

currently part of Americans with Disabilities Act Accessibility Guidelines.

The purpose of the NCIDQ Building Codes is to create a standardized set of

requirements for candidates across the US and Canada.

Qpractice recommends understanding this requirement so that you are able to

draw and dimension correctly, and check to see if the codes given with your

exam include this.

Accessible Toilet

16-18” centerline

18” centerline if using the standard 6” and 12” distance from wall on ASID

Template

17-19” H

Urinals

Urinals are not required by the plumbing codes in all occupancies. However, if

only one urinal is provided, neither the IBC nor the 2010 ADA Standards require

the urinal to be accessible. If two or more urinals are provided, then at least one

is required to be accessible (this is because there is an accessible stall).

For the NCIDQ Exam, always refer to program requirements

Urinal screens

Urinal privacy screen requirements vary in IBC - IPC and ADA.

It is best practice design to include a urinal screen.

When a privacy panel is used at an accessible urinal, it can be located either

inside or outside the clear floor space. If it is located inside the required clear

floor space, it cannot extend past the front edge of the urinal rim.

Depth of screen at standard urinal is 18”D, and can be no more than 6” past the

rim.

Standard Urinal

24” H

30” between panels will work for regular and ADA

Accessible Urinals

17” H

13 ½” min. D with elongated rim

Show the 30” x 48” clear floor space pulled up to rim of urinal

Lavatories

Standard or Accessible

30” centerline to centerline for multiple lavatories in continuous counter

30” minimum from centerline to toilet/water closet

Show faucet and lever handles, draw a quick "T"

Have not been required in the accessible stall, but always go by the program

instructions

Mount 34”H in counter

Mount 34” H wall hung for standard or accessible

Show single mirror over counter, or single mirror per each wall hung

Mirror with bottom edge starting at 40”H maximum for accessible lavatory

Mirrors above 34” counter with 4” backsplash, will typically be flush at 38”H
