Typical Program Requirements You must meet both program requirements and codes to pass this drawing. The drawing requirements are all similar, the fixture counts vary. This drawing is always a commercial men s room. Program Requirements Draw and tag specified plumbing fixtures and accessories in a public restroom [washroom] for men Lavatories, with at least one (1) accessible Toilets, with at least one (1) accessible Urinals, with at least one (1) accessible Grab bars as required Mirror at each lavatory Soap dispenser(s) Accessible hand dryer Accessible trash receptacle Dimension Fixture centerlines Toilet stalls Grab bars Draw barrier-free clearances Complete a fixture and accessory schedule indicating proper mounting heights Accessible mounting heights for all accessible fixtures Indicate front or side approach for designated height of hand dryer and trash
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? 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.
Building Codes and Standards The following building codes are used in various parts of the United States and Canada. Building Codes The following building codes are used in various parts of the United States and Canada: IBC International Building Code Life Safety Code of the National Fire Protection Association (NFPA) National Building Code of Canada Standards Americans with Disabilities Act Accessibility Guidelines (ADAAG) and ADA- ABA (Architectural Barriers Act) Guidelines American National Standards Institute (ANSI), "Specifications for Making Buildings and Facilities Accessible to and Usable by Physically Handicapped People" Environmental Protection Agency (EPA) Standards and Practices From: http://www.ncidqexam.org/exam/referencematerials/ References Qpractice NCIDQ Exam Guide Interior Design Reference Manual Codes Guidebook for Interiors Practicum Exam Guide NCIDQ Building Codes NCIDQ Interior Design Practicum Practice Exam (Ballast) - note that this
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. lavatory - used in a bathroom, restroom, or washroom and can be wall hung 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 Applicable NCIDQ Codes 5.3 ALL accessible (barrier-free) counters MUST have clear knee space of at least 30"W x 17"D [760 mm x 430 mm]. 5.4 ALL exposed hot water pipes and drains MUST be insulated or otherwise protect wheelchair users from burns on the legs. 5.5 ALL accessible (barrier-free) wall-mounted controls MUST be located between 15" [380 mm] and 44" [1100 mm] AFF for a Forward Reach and between 9 [230 mm] and 48 [1200 mm] AFF for a Side Reach. 5.8 Restrooms [Washrooms] 5.8.1 ALL accessible toilets MUST have an unobstructed 60 [1500 mm] turning circle. 5.8.2 Centerline of accessible toilets MUST be 16-18 [400 mm - 450 mm] from side wall or partition. 5.8.3 Clearance around accessible toilets MUST be 60 [1500 mm] along the rear wall and 56 [1420 mm] along the side wall.

Accessible Clearances Demonstrate that you understand the accessibility requirements for this drawing by showing these accessible clearances General Minimum corridor or passage width is 44 60 turning circle at all changes in direction Turning Circle This represents clear space on the floor required for turning while using a wheelchair. 60 diameter in accessible stall and at all changes in direction CAN T overlap toilet or door swing CAN overlap 30 x48 clear floor space CAN overlap grab bar (because they are on the wall not the floor) Show clearance of 60 at the rear x 56 at side wall in the stall in addition to turning circle. 30" x 48" Clear Floor Space Show at lavatories, pull under 17 Pull up to rim of urinal, can adjoin or overlap accessible route Show at restroom accessories to match approach as noted in schedule CAN overlap turning circle (each represents a single wheelchair user who will only
be in one place at a time) CAN T overlap door swings Front & Side Reach Approach drawn on the plan must match the schedule Mounting height as listed must be within front or side reach range per NCIDQ Building Codes 40 falls within both reach ranges, and maximum mounting height for bottom edge of mirror Clear Knee Space Show 30 x 48 clear floor space pulled up under the lavatory, 30 W x 17 D
Annotations & Dimensions Use the following annotation and dimension standards on your drawing and schedule. Dimension Running dimensions of fixture centerlines from fixed point Dimension length and width of each stall Grab bars - dimension length of each with distance from wall Units 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 Use 4-6 for interior partitions, ½ - 1 for toilet partitions Dimension or annotate accessories as recessed and projection from wall Draw barrier-free clearances 60 unobstructed turning circle within accessible stall and at all changes in direction 60 x 56 at accessible stall Push/pull clearances at accessible stall 30 x 48 clear space with forward or side reach as listed in schedule 30 x 17 clear space (show 30 x 48 pulled under lavatory) Annotations / Schedules Complete a fixture and accessory schedule indicating proper mounting heights Note "pipes to be wrapped and insulated"
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 & Doors Use these standards for partitions and doors 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
Fixtures Including accessible and standard toilets, urinals, stalls, grab bars and lavatories 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
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. Buildings and facilities shall be designed and constructed to be accessible 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
