BIFMA has been very busy the last few years on the seating front.
They published BIFMA X5.11 for large occupant (254-400 lbs) in 2015 and they have a draft standard on the back burner for healthcare furniture; BIFMA HCF 8.2.
Both standards share some tests from BIFMA X5.1 and BIFMA X5.4 and incorporate new tests as well. There is still no BIFMA bariatric standard. However HCF 8.2 goes up to 600 lbs which is getting pretty close to the bariatric realm.
Bariatric: Relating to or specializing in the treatment of obesity.
ANSI/BIFMA X7.1 This standard defines the acceptance criteria for VOC emissions from furniture used in offices to be classified as low-emitting product and should be used in conjunction with the
ANSI/BIFMA M7.1 Standard Test Method for Determining VOC Emissions from Office Furniture Systems, Components and Seating.
ANSI/BIFMA e3 Furniture Sustainability Standard. The purpose of this voluntary standard is to provide measurable market-based definitions of progressively more sustainable furniture by establishing performance criteria addressing environmental and social impacts throughout the supply chain. It addresses product-based characteristics in the general areas of environmental, health and wellness, and social impacts.
NSF/ANSI 336 The purpose of the Standard is to address the environmental, economic and social aspects of commercial furnishings fabric used in public occupancy settings such as office, hospitality, healthcare and institutional interiors. These textiles include but are not limited to woven, non- woven, bonded, knitted, felted and composite materials used for upholstered furniture; walls,
draperies, cubicles, furniture systems and other vertical applications; and decorative top-of- bed applications such as bedspreads.

We refer to unwanted, annoying, or discordant sounds as noise. Noise from outside of a space can be controlled in the following ways:
-Isolate the noise at its source.
-Locate noisy areas as far away as possible from quiet areas.
-Reduce the transmission of sound from one space to another.
Sound attenuation can be used to improve the sound within a space, such as speech clarity.

Another type of extinguishing agent is actually a building material and acts passively in reaction to a fire.
Intumescent materials respond to fire by expanding rapidly, insulating the surfaces they protect by filling the gaps to prevent the passage of fire, heat and smoke. For example, a strip of intumescent material placed along the edge of one of a pair of fire doors will expand and seal the crack, substituting for an astragal (molding) that would otherwise be required

When two or more exits are required, the code requires that at least two of the exits be remote enough from one another so that both cannot easily be blocked by one fire. This is often referred to as the half‐diagonal rule. Typically, the distance between two exits must be at least 1/2 (one‐half) of the longest diagonal distance within the building or the building area the exits are serving.
However, if the entire building is equipped with an automatic sprinkler system, most codes allow the minimum distance to be 1/3 (one-third) of the diagonal distance. So, the
distance can be reduced.
48 ÷ 3 = 16
The space depicted has been classified as an
Assembly Occupancy requiring 2 exits. The building is sprinklered throughout. What is the minimum required distance between exits, noted as value 'L'?
A. No minimum distance required as the building is sprinklered throughout

The key to this question is recognizing that the wall sconce is in a corridor, not over a counter, table, or other work surface, so it projects into the path of travel.
1003.3.3 Horizontal projections.
Objects with leading edges more than 27 inches (685 mm) and not more than 80 inches (2030 mm) above the finished floor shall not project horizontally more than 4 inches ( mm) into the circulation path.
A wall sconce you have specified projects 5′′ from the
wall into a corridor. What is the minimum mounting height?
detailed is matched to an existing installation is to use a reference note calling to the Contractor to match existing site conditions. The Contractor can contract the work to the required sub- trades instead of the designer using their best guess to match to existing. Always ask for samples to be submitted to the designer before ordering or fabrication the matched item, so the designer can go to the site to ensure a perfect match.
A renovation project has complex blueprint matched
veneer paneled walls with a unique ceiling to wall transition detail, which the Interior Designer is trying to match. What would be the BEST way to go about detailing the construction drawings to ensure a
seamless transition between existing and new paneled walls?
A. Ask the client for record drawings of the existing space to find details on how the existing paneled wall was constructed
B. Go to site, take detailed measurements and samples of the wood, and ask a millworker to write a specification that he thinks most closely matches the
existing work
C. Add a reference note to the working drawings asking the contractor to match to existing site conditions, to notify designer of any discrepancies, and to provide shop drawings prior to starting any construction to ensure a perfect match
D. Come up with a new detail that coordinates with the existing construction, but does not match
B. reflected ceiling plan
A reflected ceiling plan shows a view of the ceiling as though it were reflected onto a mirror.
RCPs show partitions that extend to the ceiling and those that extend through the ceiling. They also show ceiling materials, building grid lines, notes calling out ceiling heights, changes in ceiling heights, location of all lights (including exit lights) sprinkler
heads, air diffusers and vents, access panels, speakers and any other item that is part of or touches the plane of the ceiling.
Which drawing would an interior designer create to document the lighting system to include the location of all light fixtures specified?
A. switching plan
B. reflected ceiling plan
C. electrical plan
D. ceiling section plan
A. Flush overlay construction
Source: Qpractice NCIDQ Exam Guide, Specialty Drawings
Flush overlay construction is when the door or drawer overlaps the face frame of the cabinet with a very minimal gap between doors or drawers. This results in a clean look to the front of the cabinets as only the doors and drawers are visible. This is not the same as flush
construction, where the face of the drawer or door is installed flush with the face frame.
What type of cabinet construction best describes the
following image?
A. Flush overlay construction
B. Reveal overlay construction
C. Flush construction
C. an elevation reference
Source: Interior Design Reference Manual, 6th Edition, Measurement and Drafting, Reference Systems
An elevation reference mark, often called an elevation bubble, is placed on a floor plan to indicate that an elevation of the wall or walls is drawn somewhere in the set.
The number on top of the line indicates the unique sequential number of the elevation drawing, and the number below the line indicates the sheet on which the drawing is placed.
What mark is placed on a floor plan to indicate that an elevation of a wall or walls is drawn somewhere in the drawing set?
A. reference bubble
B. a section reference
C. an elevation reference
D. a detail reference
D. shows power sources and outlets
The electrical engineer designs and produces the drawings and specifications for the power system (outlets and equipment) and the lighting system.
On most projects the electrical engineer will also design the telephone system, signal systems and security systems. For large or complex projects, the interior designer
sometimes draws a separate power plan or telephone plan showing the locations of electrical outlets, telephone outlets, and other signal systems to show coordination with interior items like furniture and built-in millwork.
All of the following are true about reflected ceiling plans EXCEPT?
A. shows ceiling materials
B. shows a view of the ceiling as though it were reflected onto a mirror on the floor
C. shows partitions that extend to the ceiling and those that extend through the ceiling
D. shows power sources and outlets
B. B

The terms “ three-way switch ” and “ four-way switch ” are often confusing because the numbers do not refer to the number of locations from which control is possible. Rather, the numbers refer to the number of conductors required to make the switching possible. For example, a three-way switch required three conductors (not including the ground) to make it possible to control a light from two different switches.
In the image below, which of the symbols would you use to represent a light switch that can be controlled from two different locations?
A. A
B. B
C. C
D. D
