IDPX Sample Test 3

Which type of structural system in an existing building would allow for the easiest penetration for a new stair between two floors? A) beam and girder steel B) flat plate concrete C) hollow-core slab D) open web steel joints

A A beam and girder steel system would most likely be covered with a concrete slab on steel decking. This would be the easiest to penetrate for a large opening between beams. Even if one beam had to be removed to provide a larger opening, additional reinforcing beams could be installed to frame the new opening. Flat plate concrete contains a dense grid of reinforcing steel. Cutting the existing steel would weaken the overall structure too much (although it would be technically possible to reinforce the opening.) A hollow-core concrete slab is also integrally reinforced, and cutting a large opening would weaken the overall span. Open web steel joists span longer distances, with spacing from 2' to 6'. This would limit the size of the opening to the joist spacing and would probably not be enough for a stairway.

Which document provides the designer with verification that an item was ordered correctly? A) acknowledgment B) bill of lading C) packing slip D) purchase order

A A manufacturer issues an acknowledgment after receiving a purchase order. Because the information on the purchase order is repeated, the designer can compare this with the original purchase order to make sure they match.

What testing standard should be specified for the durability of office chair construction? A) ANSI/BIFMA X5.1 B) ASTM D4157 C) CAL TB133 D) NFPA 701

A ASTM D4157 is the Wyzenbeck abrasion resisitance test and is used only for fabrics, not for the construction of the chair itself. CAL TB133 is the full seating test and is used for flammability testing. NFPA 701 is the vertical ignition test for the flammability of draperies or window treatments. ANSI/BIFMA X5.1, American National Standard for Office Furnishings--General Purpose Office Chairs: This standard provides manufacturers, specifiers, and users with a common basis for evaluating the safety, durability, and structural adequacy of office chairs, including criteria for factors such as swivel/til mechanisms, seating impact, front and rear stability, back durability, and footing durability.

What type of system would be BEST for an open office plan so that the heating and cooling for each workstation could be individually controlled? A) all-air system B) all-water system C) radiant panel system D) air-water system

A An all-air system can be subdivided into as many individually controlled areas as needed. Radiant panels could be used, but it would be awkward to locate them in the ceiling and the cost would be much higher than that of an all-air system. Radiant panels also would not provide for cooling.

A device used to protect against fires from faulty wiring is a(n) A) arc-fault interrupter B) circuit breaker C) disconnect switch D) ground fault interrupter

A An arc-fault interrupter detects arcing of electricity, such as that caused by faulty wiring of a lamp, and de-energizes the circuit. Arc-fault interrupters are designed to address fire hazards. Both arc-fault interrupters and ground fault interrupters can be installed as a receptacle or as part of a circuit breaker. However, arc-fault interrupters are also required to serve lighting, as they are generally placed in the breaker box. A circuit breaker detects overcurrents and operates much more slowly than an arc-fault interrupter. A disconnect switch must be operated manually. Ground fault interrupters (also called ground fault circuit interrupters) detect small leaks of current to an unintended grounding source, such as when someone touches a faulty device and a water pipe, and de-energizes the circuit. They are designed to address shock hazards and are required in areas near water, such as bathrooms, kitchens, and laundry rooms.

An interior designer recommends that a client purchase appliances directly rather than through a general contractor. What would be the primary reason for this recommendation? A) The client could avoid the contractor's markup. B) The client could not be overcharged for delivery and installation. C) The interior designer could provide the client a broader selection by acting as the client's agent D) The client could get a better discount than the contractor

A Because general contractors add their overhead and profit charges (anywhere from about 10% to 20%) to all subcontracted work, the clinet would be paying that much extra for the appliances without the general contractor doing much work for the extra cost. Option D is incorrect because the interior designer could get about the same discount for the client as the contractor would, without the contractor's markup.

An interior designer has been retained for a building project that is currently being planned by an architect. On the second floor of the building, slate flooring over a concrete subfloor is being used. What type of installation should ideally be designed for? A) a thick-set application using a cleavage membrane B) a bonded quick-set installation C) a 1/2" layer of mortar with the stone dry-set tup D) a standard thin-set installation

A Because slate does not have a uniform thickness and a concrete subfloor above grade may deflect and cause cracking, the best installation is a thick-set method with a cleavage membrane. The thick-set method allows the tile setter to adjust the bed according to the exact thickness of each stone, and a cleavage membrane (with reinforcement) allows the finish floor to float above any slight deflection of the concrete floor.

In planning an efficient mountain cabin, what is the minimum floor area that an interior designer could plan for each of the children's bedrooms? A) 70 ft² B) 100 ft² C) 120 ft² D) 140 ft²

A Both the International Building Code (IBC) and the International Residential Cod (IRC) require that a dwelling have at least one room with a minimum floor area of 120 ft² with no other room less than 70 ft². Presumably the larger room would be the living room, so the children's bedrooms could be a minimum of 70 ft².

During design development of a commercial office space, the interior designer can minimize energy use by coordinating space planning with A) daylighting zones B) HVAC zones C) occupant sensor controls D) time-switch controls

A Daylighting zones are areas near windows, roof monitors, and skylights where daylight-responsive controls are required by the International Energy Conservation Cod (IECC). The IECC defines where these zone are located based on the size of the fenestrations, ceiling height, and obstructions. In section view, the daylight zone extends as far into the building from the window as the distance from the floor to the top of the window. In plan view, it extends 2' on either side of the window jamb, or to the nearest wall, whichever is less. When planning the interior configuration, the designer should determine where these spaces are and located uses within them that can function will with daylight-responsive controls. Other types of lighting controls should be specified for space beyond these zones. HVAC zones are established by the mechanical engineer and generally function independently of area that the interior designer may have control over, which might amount to any significant energy savings. Occupant sensor controls, although important for energy savings, only detect the presence or absence of people within an area and turn the lighting or other devices on or off. Tehy do not related directly to space planning, especially during design development. Time-switch controls turn off lights or other loads automatically based on time schedules, such as overnight or on holidays.

Exits are ALWAYS A) protected by fire-resistance-rated construction B) limited in length C) constructed as either corridors or stairways D) required to have a 2-hour rating

A Exits must always be protected by fire-resistance-rated construction. They are not limited to length. Exits may be as simple as exterior exit doors at ground level or may include exit enclosures for stairways. Depending on the building height, construction type, and passageway length, exits bust have either a 1- or 2-hour rating.

Which type of structural system would allow for the highest finished ceiling? A) flat plate B) flat slab C) open web steel joist D) waffle slab

A Flat plate construction consists of a single thickness of reinforced concrete supported by columns. Except for the columns, there are no structural elements below the underside of the slab, making it possible to place needed services as high as possible, thereby allowing for the highest finished ceiling. A flat slab includes concrete drop panels (either square, round, or cone shaped) around each of the columns to increase strength. These drop panels prevent the installation of services near the columns, decreasing the possible finished ceiling height. Both open web steel joist and waffle slab systems occupy much more space than a flat plate slab and would require a lower finished ceiling height after services are installed.

In a material does not burn, it is considered to be A) fire retardant B) fire rated C) flame resistant D) noncombustible

D By definition, a material that does not ignite or burn is considered noncombustible.

A clothing store located on the ground floor contains 15,000 ft² of retail area, a 2000 ft² space for fashion shows for seated audience with small cocktail tables, and a 3000 ft² stock room. Using the table show, determine the total occupant load. A) 394 occupants B) 434 occupants C) 546 occupants D) 660 occupants

A From the table, mercantile areas have an occpant load of 60 ft² per occupant. An assembly area without fixed seats of unconcentrated use has an occupant load of 15 ft². A stock room has an occupant load of 300 ft² per occupent. Therefore mercantile = 15,000 ft²/60 ft²/occupant = 250 occupants assembly = 2000 ft²/15 ft²/occupant = 133.33 occupants (134 occupants) stock room = 3000 ft²/300 ft²/occupant = 10 occupants total = 250 + 134 + 10 = 394 occupants

Which of the following is the BEST choice for safety glazing in a hazardous location? A) tempered or laminated glass B) tempered or wired glass C) heat-strengthened glass or wired glass D) laminated or wired glass

A Only tempered and laminated glass are considered to be safety glazing because they meet the requirements of 16 CFR 1201. Although the 2012 edition of the International Building Cod (IBC) does permit the use of wired glass that meets the requirements of ANSI Z97.1 in certain applications, the question does not specify this compliance. Furthermore, neither wired glass nor heat-strengthened glass meet the requirements of 16 CFR 1201.

Under what conditions would a 1 3/4" thick hollow metal door be used? A) when a fire rating over 90 minutes and high security and durability are required B) when a fire rating over 1 hour is required or a steel frame is necessary C) when the door opening is expected to receive heavy use and smoke-proof opening is required D) when the door will receive minimal maintenance under heavy use

A Option B is incorrect because a solid-core, wood door in a steel frame could be used to meet the conditions. Option C is incorrect because a smoke-proof opening can be achievedd with a wood door, as well as with a hollow metal door. Option D is a possible choice, but minimal maintenance under heavy use does not necessarily imply a metal door.

Which of the following organizations or standards establishes volatile organic compound (VOC) limits on indoor air quality for furniture systems? A) BIFMA B) EPA C) IBC D) IECC

A Standards for VOC limits on furniture systems are established by BIFMA e3, Furniture Sustainability Standard. It is applicable to movable walls, systems furniture, desking systems, casegoods, tables, seating, and accessories. Annex C of the standard lists concentration limits for over 30 individual VOC chemical compounds for workstations, seating, and individual components. The e3 standard references ANSI/BIFMA M7.1, Standard Test Metho for Determining VOC Emissions from Office Furniture Systems, Componients, and Seating, and ANSI/BIFMA X7.1, Standard for Formaldehyde & TVOC Emissions of Low-emitting Office Furniture Systems and Seating. The Environmental Protection Agency (EPA) establishes limits only on VOCs for coatings. The International Building Code (IBC) and International Energy Conservation Code (IECC) do not establish limits on VOCs.

A designer has calculated the occupant load of a large, sprinklered hotel ballroom, and has determined that three exits are required from the space. The diagonal distance of the room is 160 ft. According to the International Building Code (IBC), two of the exits must be separated by at least one-third of the diagonal distance of the room. Where does the code require the third exit to be located? A) a reasonable distance from the others B) a minimum of 80 ft from the first two C) as determined by the building official D) at least one-half the diagonal distance from the first two.

A The IBC requires that when three or four exits are required, two of the exits must be place at least one-half the diagonal distance of the space for nonsprinklered spaces, and one-third the diagonal distance for sprinklered spaces. The third exit must be arranged a reasonable distance from the other two, so that if one of those exits becomes blocked, the other two will remain available.

Which of the following terms represents the efficiency of a luminaire in distributing lamp light to room surfaces? A) coefficient of utilization B) lamp lumen depreciation factor C) lamp luminance D) luminaire efficacy

A The coefficient of utilization (commonly abreviated "CU") is a value that is determined and published by the manufacturer. It represents the efficiency of a luminaire in distributing light from a lamp under various degrees of finish reflectivity to the floor, walls, and ceiling.

An occupant load calculation has shown that the office suite requires a total of 71" of egress width and two exit access doors. In order to meet all International Building Code (IBC) and accessibility requirements, what are the minimum door widths that should be used? A) one 36" door and one 42" door B) one 38" door and one 34" door C) one 36" door and one 44" door D) two 36" doors

A The combination of a 36" and 42" door provides a total 72" ( 33" + 39" = 72") of clear width. These are the minimum door widths that will satisfy the 71" total egress width requirement. The required width for both egress doors and doors used for accessibility is the clear width, not the size of the door. Accessibility guidelines require a 32" minimum clear width. The thickness of the door itself and the hinge space make the clear width for commercial door assemblies about 3" less than the actual door width. A 36" door has an actual clear opening of 33". Therefore, a 34" door cannot be used because the clear opening would not be wide enough to comply with the accessibility requirements. The combination of a 36" door and a 44" door would provide a clear width (74"), which would satisfy egress width requirements, but the problem asks for the minimum possible sizes. The combination of two 36" doors would only provide 66" of clear width.

After creating the reception desk section detail, the interior designer must consult with the A) electrical engineer B) building owner C) furniture dealer D) mechanical engineer

A The custom-designed reception desk section includes an under-counter light and an electrical connection that is hard-wired through the floor. Therefore, the electrical engineer needs to be consulted to confirm the location of the electrical stubs on the electrical plans, and to confirm the requirements for the conduit size, access panels, and types of connection.

What is the MOST important criterion for lighting a fabric showroom? A) visual comfort probability B) color rendering index C) coefficient of utilization D) apparent color temperature rating

B In a fabric showroom, accurate color rendition is an important concern. Therefor, option B and D are the most likely choices. Although the color temperature rating of the lamp gives a general indication of the lamp's "whiteness," the color rendering index (or "CRI") is a more accurate indication of how appropriate a lamp is for a specific application.

A residential client with a one-story house wants to remove an 8' section of a load-bearing wall to make an opening between two existing rooms. What is the MOST appropriate advice the interior designer can give? A) The opening can be framed, but a structural engineer will be needed B) An architect will have to be retained to sign the drawings for the building department C) The opening can be framed with a double 2" x 8" header. D) The proposed opening cannot be made because the wall is a load-bearing wall.

A The opening can be framed, but a structural engineer will be needed. Option B is incorrect because an architect would have to do more than just sign the drawings; structural calculations would be necessary. Option C is incorrect because the interior designer is not qualified to determine what type of header is needed. Option D is incorrect because the opening can be made as long as it is engineered properly by a qualified professional.

In starting a design project in a multi-use building, what information would an interior designer need to determine? A) construction type, adjacent occupancies, and sprinkler condition B) construction type, fire-zone classification, and accessibility requirements C) adjacent occupancies, sprinkler conditions, and fire-zone classification D) adjacent occupancies, fire-zone classification, and accessibility requirements

A The question implies that the design process cannot proceed without some basic data that the interior designer might not otherwise have about the building. The most important are construction type, adjacent occupancies, and sprinkler condition. Construction type could affect the maximum area of the client's proposed use and how the designer would have to detail shaft walls and structural enclosures. Adjacent occupancy groups would affect what rating the designer felt would be needed between the client's space and the existing spaces. Knowing whether or not a building is fully sprinklered would affect the maximum allowable area, finishes, and other design and detailing decisions. Fire-zone classifications are generally irrelevant for the interior design work. Accessibility requirements are necessary, but the requirements themselves do not relate to the building.

What type of sprinkler head should be used for a decorative, open-grid, wood-slat ceiling suspended from the structural floor above? A) upright B) pendant C) sidewall D) recessed

A Upright sprinklers disperse the water upward so coverage is provided above and below the suspended wood-slat ceiling.

A client has requested that special security protection be provided at a reasonable cost for critical paper files containing corporate trade secrets. In designing the file room, the interior designer should suggest A) card readers at the doors leading to the file room B) photoelectric beams within the rooms C) magnetic contacts on all doors leading to the file room D) electronic shielding of the file room

A Card readers would be the most cost-effective solution because they could provide access control, as well as notification if there is an attempt at unauthorized entry.

What is the interor designer's BEST course of action if a client wants to remove part of a partition thought to be a bearing wall? A) have a structural engineer or architect review the problem and make a recommendation B) look in the attic to see if the wall supports any beams or joints C) ask the client for the building's structural drawings and review them D) check for structural stability by tapping on the wall and determining where it is located in relation to the center of the building

A In any situation that involves or might involve a structural question, an engineer or architect should be consulted.

In which of the following building types are fire-resistive construction requirements likely to be the greatest? (Choose the three that apply.) A) Type I B) Type II-A C) Type II-B D) Type III E) Type IV F) Type V-A

A, B, C Type I and II are noncombustible building types and have the most fire-resistive construction of those listed. Type A subgroups have a higher hourly rating for some components that Type B subgroups. Types III, IV, and V may include combustible components for some of the major elements.

Which of the following are found in the project manual? (Choose the four that apply.) A) performance bond B) testing requirements C) instructions for bidders D) cost estimate E) Owner-Interior Designer Agreement F) supplementary conditions

A, B, D, F Performance bonds, resting requirements, instructions to bidders, and supplementary conditions are typically found in the project manual. Cost estimates are never placed in the project manual because the project manual is used for bidding. Agreements between the interior designer and owner are not included either.

The interior designer is responsible for which of the following aspects of consultant coordination? (Choose the four that apply.) A) giving the electrical engineer information about the client's equipment B) providing the mechanical engineer with the occupant load for each space C) informing the mechanical engineer about current sprinkler system codes D) making sure that the final drawings and specifications are coordinated E) telling the electrical engineer where to place the electrical closets F) giving the electrical engineer the designer's preferred choices for luminaires

A, B, D, F The interior designer is responsible for giving the electrical and mechanical engineers information about equipment or occupants so that they can accurately calculate electrical loading and HVAC system requirements. The interior designer also has overall responsibility for making sure all consultants' documents are coordinated with the interior design documents. The mechanical engineer (or fire protection engineer, if there is a separate consultant) is the person responsible for staying current with all code requirements in the project's jurisdiction. The location of the electrical closets is predetermined by the building architect, not the interior designer.

Which of the following are correct statements about corridors? (Choose the three that apply.) A) Corridors are part of the exit access B) Corridors are part of the exit C) Corridors must be used exclusively for egress D) Corridor construction must be fire rated E) Corridors are included in calculating travel distance F) Corridors must never have dead ends

A, C, E Corridors are part of the exit access portion of the egress system, not the exit portion. This means that they are used for calculating travel distance, but they do not necessarily have to be fire rated (although they usually are). Also, by definition, they must be used exclusively for egress. Dead-end corridors are allowed within certain limitations; for example to 20' in a nonsprinklered building.

In specifying new window coverings and tracks to replace building-standard window coverings, what coordination is MOST important for the interior designer to undertake? (Choose the four that apply.) A) verifying that the building owner approves of the changes in the building's exterior appearance B) asking the electrical engineer if the new light reflectance is detrimental C) determining if the mechanical engineer objects to the replacement plans D) getting approval from the client concerning the color of the coverings E) verifying with the manufacturer that flammability does not pose a problem F) checking with the architect to see that the new coverings do not adversely affect the heating of the glass

A, C, E, F New window coverings can affect the exterior appearance of a building, which might be objectionable to the building owner. They can also affect the mechanical system, so the mechanical engineer should be consulted. The new coverings must meet flammability requirements, so the manufacturer should be consulted. Also, the location of the window covering relative to the glass can put additional heat stress on the glass, causing cracking or breaking. Although light reflectance might be affected, it would be minor and probably would not affect the overall light quality in the room. While the client's opinion about color is important, it is not the most critical coordination item, because once the other factors have been coordinated, an acceptable color and pattern can be found.

When the interior designer does not want furniture to be delivered to the designer's office, the designer should complete a A) customized purchase order B) drop ship order C) letter of intent D) tag for label

B A drop ship order is simply a purchase order requesting that merchandise be delivered somewhere other than the address of the person or company ordering the merchandise.

An interior designer is evaluating various alternatives for a particular building product as they relate to sustainability. The interior designer would MOST likely use a(n) A) environmental impact study B) life-cycle assessment C) impact assessment D) matrix comparison chart

B A life-cycle assessment evaluates the environmental impact of using a particular material over its entire life, including disposal. It could be used to compare the impacts of two or more materials so the architect could select the most sustainable one. Option A is incorrect because an environmental impact study is used to evaluate the impact of a development on the environment. Option C is incorrect because an impact assessment is one phase of a life-cycle assessment. Option D is incorrect because there is not sustainability evaluation method by that name.

ASTM is a(n) A) model code group B) industry standard-writing organization C) testing laboratory D) federal code-writing agency

B ASTM International, formerly known as the American Society for Testing and Materials, is one of the organizations that establish a wide variety of standards covering testing methods, products, definitions, and more. Although its committees develop test methods, it is not a testing laboratory.

Surface-mounted luminaires are MOST often used for which of the following reasons? A) Some side and uplighting is desired B) There is not enough space above the ceiling C) They are easier and less expensive to install D) They are used as a design feature.

B Although all the choices are possible reasons for using surface-mounted luminaires, the lighting fixtures are most often employed when space is inadequate for recessing.

Who is responsible for showing the telephone and data conduit runs on the drawings for a commercial design project? A) architect B) electrical engineer C) interior designer D) telephone installer

B Although the interior designer will indicate the desired location of telephone and data outlets based on client feedback obtained during the programming process, the electrical engineer is responsible for showing the actual conduit runs for the wiring.

Which of the following pairs of building code requirements is MOST critical for the interior designer to know before starting preliminary space planning? A) occupancy group and total floor area B) number of exists and maximum distance to exits C) allowable length of dead-end corridors and glazing requirements D) occupant load and corridor construction requirements

B Although there are many building code requirements that the designer needs to know before starting to plan, of the options given, only the number of exits and the maximum distance to exits are critical for preliminary space layout. Option A is incorrect because neither the occupancy group nor the floor area helps to suggest how the space should be laid out. Option C is incorrect because glazing requirements are not a critical element. Option D is incorrect because the details of corridor construction are not needed at this stage; only the corridor locations are needed.

In preparing an FF&E budget, where would the interior designer get the MOST accurate cost information on a sofa? A) furniture manufacturer B) furniture dealer C) internet D) merchandise mart

B Because furniture dealers actually sell the furniture to designers at whatever trade discount is available, they would be the best source for current, accurate prices. Furniture manufacturers sell only to the dealers and only suggest retail prices. The internet would not have the prices, including trade discounts, that are available to the designer. A merchandise mart leases space to dealers and is not involved in pricing for the merchandise.

Furniture budgets can be accurately estimated by the A) general contractor and furniture manufacturer B) interior designer and furniture dealers C) furniture representative and client D) furniture manufacturer and interior designer

B Because the furniture dealer and the interior designer are the two people closest to the specification and ordering of furniture, option B is correct. Furniture manufacturers, general contractors, and clients are seldom, if ever, involved in budgeting furniture.

Which of the following must have AT LEAST a Class III (or C) fire rating? A) bookshelves B) wainscoting C) built-in base cabinets D) door and window trim

B Building codes generally require flame-spread classification for wall finishes only; this includes wainscoting. Other types of woodwork, such as bookshelves, cabinets, and door and window trim, do not require a particular fire rating.

Which type of sink is BEST for barrier-free design? A) vanity B) pedestal C) wall hung D) free standing

C All the sink installations listed as possible options can work if they meet the measurement requirements shown in the following illustration, but a wall-hung lavatory gives the most open access, usually exceeding the minimum requirements.

As construction work begins on a large commercial project, the interior designer is concerned about coordinating the installation of services in the plenum so that sufficient space is allowed for planned recessed lighting and raised ceilings. Which type of subcontractor should the designer have the general contractor coordinate with first? A) electrical B) mechanical C) plumbing D) sprinkler

B In the sequence of construction, the mechanical ductwork and other mechanical equipment are the first things to be installed, and also the most difficult to modify once in place. The interior designer should discuss and verify with the general contracot and mechanical subcontractor what areas of the space will need sufficient room to provide for luminaires and raised ceilings Electrical work is usually the last service to be installed and can easily be routed to avoid recessed lighting and raised ceilings. Plumbing is typically not extensive, is installed after the mechanical work, and can usually accommodate the location of other services. Sprinkler piping is typically installed after the mechanical work and provides some flexibility in avoiding recessed lighting and raised ceilings.

An interior designer has written furniture specifications fora project and has put the job out for bid to several dealerships. In this situation, purchase orders are MOST likely to be written by the A) owner B) dealership C) furniture rep D) interior designer

B In this situation, the dealership would most likely provide the ordering, delivery, and installation services, including the paperwok needed.

When designing a project in an unfamiliar city, what is the BEST source of cost data? A) the most current cost data book with prices adjusted for geographical location and inflation B) a local contractor who builds projects of a similar type C) a computerized cost database targeting for that city D) interior designers and architects who practice in that city and design projects of a similar type

B Option A is incorrect because cost books are dated by the time they are published. Option C is not the best choice because it does not account for current variations in prices or the unique nature of a particular job. Option D is a possibility, but given the choice between designers and contractors, the contractors are most likely to be the best source of data.

In addition to construction, what are the major cost components of MOST interior design projects? A) furnishings, taxes, signal systems, and moving B) furnishings, professional fees, taxes, and telephone installation C) fixtures, overhead and profit, moving, and telephone installation D) furniture, fixtures, taxes, and moving

B Option A is incorrect because it is missing professional fees. Option C is incorrect because it does not include furnishings, an obvious, major component of an interior project. Option D is incorrect because it is missing professional fees and telephone installation.

A 216 pitch carpet has A) a pile height that is almost 1/4" high B) 8 surface yarns per inch C) an equivalent gauge of 1/6 D) a commercial-grade stitch rate

B Pitch is the number of ends of surface yarn in a 27" width. To convert this measurement to gauge (the spacing between the stitches), divide 27" into 216 stitches. This gives 8 stitches/in, or 8 surface yarns/in. The equivalent gauge, therefore, is 1/8.

In addition to meeting the requirements of the ADA, what other accessibility requirements should the interior designer be MOST concerned with when doing design development for a commercial project? A) ANSI A117.1, Accessible and Usable Buildings and Facilities B) scoping provisions of the local building code C) ADA/ABA Guidelines D) Uniform Federal Accessibility Standards

B Scoping provisions tell the designer how much of something is required. Although there are scoping provisions in the ADA, local codes may be more stringent, in which case the interior designer must conform to the more restrictive requirements. ANSI A117.1 may or may not be applicable in a given jurisdiction. If ANSI A117.1 has been adopted by the local building code, it should be reviewed to see if the requirements are more restrictive than hose of the ADA. The latest edition of A117.1 leaves scoping up to local jurisdiction. The ADA/ABA Guidelines are the ADA/ABA Accessibility Guidelines and are part of the ADA. so this option is irrelevant. The Uniform Federal Accessibility Standards are applicable to federal buildings and projects that receive federal funding and would not be used fora commercial project.

Which of the following partition wall assemblies would be the least expensive to provide a 1-hour fire rating in a Type V-A building? A) one layer of 5/8" Type X gypsum board on each side of wood studs B) one layer of 5/8" Type X gypsum board on each side of metal studs C) two layers of 1/2" gypsum board on each side of metal studs D) two layers of 5/8" Type X gypsum board on each side of wood studs

B The basic assemble for a 1-hour-rated partition uses 5/8" Type X gypsum wallboard on both sides of either wood or metal studs. In a Type V-A building, either type of stud can be used. However, metal stud framing is typically less expensive than wood framing. In order to achieve the desired rating, the partition must be constructed in accordance with the approved UL detail using the same combination of products and installation methods that has been tested in laboratory and proven to have the desired resistance rating. Using wood studs with 5/8" gypsum board on both sides of the wall would provide a 1-hour rating, but wood stud framing is typically more expensive than metal stud framing. Two layers of standard 1/2" gypsum board on each side of the studs meets the requirements for a 1-hour partition even without being Type X, but it would cost more to install two layers than a single layer.

An interior designer has determined the required gross occupant area required for a client planning to lease space in an office building. Using the Building Owners and Managers Association (BOMA) standard ANSI/BOMA Z65.1, Office Buildings: Standard Methods for Measurement, which of the following would be used to determine the amount of lease space the client will be paying for? A) building efficiency ratio B) building load factor C) R/U ratio D) rentable area

B The building load factor accounts for each tenant's share of the common areas of the building, such as restrooms, public corridors, and elevator lobbies. The building owner calculates the load factor using one of two methods, Method A and Method B, as defined by the ANSI/BOMA Z65.1 standard. Once the gross floor area of the tenant space is known, it is multiplied by the load factor to determine the total square footage upon which the rent calculations will be based. The building efficiency ratio is the ratio of the net assignable area of the building to the gross building area. The R/U ratio is the rentable area divided by the usable area of each floor in an office building and is used by Method A of ANSI/BOMA Z65.1 to determine the load factor, which may vary from floor to floor. Although basically the same as the load factor referenced in Method A, the correct term is building load factor because Method B of ANSI/BOMA Z65.1 is used to develop a building load factor that is the same for the entire building. The rentable area is what the tenant pays rent on.

Which type of chart is MOST often used with complex projects to show critical tasks and their associated times? A) bar chart B) CPM chart C) Gantt chart D) PERT chart

B The critical path method (CPM) uses a network diagram (i.e., chart) that shows all tasks required to complete a project. From the CPM chart, a path of the critical tasks defines the sequence of tasks that must be started and finished exactly on time for the schedule to be met. CPM charts also can include an analysis of the time/cost trade-offs. The program evaluation review technique (commonly referred to as a PERT chart) is similar to the CPM method, but uses different networking methods. PERT charts are NOT commonly used with complex projects because CPM charts better show critical tasks and their associated times. A bar chart (also called a Gantt chart) is a simpler representation of a schedule that does not show a critical path.

Which of the following are the two main factors used to determine whether a space must have more than one exit? A) travel distance and exit width B) occupant load and occupancy C) travel distance and occupant load D) exit width and occupancy

B The two main factors used to determine whether a space needs more than one exit are occupancy and the occupant load. The occupancy is how the space is used (e.g., business, industrial, or residential). The occupant load is the maximum number of people that may occupy the space. If the occupant load exceeds the allowable value given in the International Building Code (IBC), then one or more additional exits will be needed. Though the occupant load and occupancy are the most important factors in determining how many exits a space must have, a third factor--the travel distance--is also considered. The travel distance is the measurable distance from a space's most remote occupiable point to the entrance of the nearest exit that serves it. If this distance exceeds the limits given in the IBC, a second exit will be required, even if the occupant load is within the allowable value given in the IBC. Exit width, however is not a factor in determining a space's required number of exits.

When a double door with an astragal is included in a fire separation partition, which of the following is required? A) automatic door bottom B) door coordinator C) panic hardware D) threshold

B When an astragal is used to seal the opening between double doors and the doors are fire rated, a device known as a door coordinator is needed to automatically close one leaf of the pair of doors before the leaf with the attached astragal closes. This is to prevent incomplete closing of the doors. An automatic door bottom and threshold are not necessary. Panic hardware is only required in specific situations defined in the building code, where the double doors are exit doors in occupancies with large numbers of people.

Safety glazing is required in which of the following? (Choose the three that apply.) A) glass panels where the sill is greater than 18" above the floor B) glass sidelights next to a solid wood door C) shower doors D) full-height glass panels less than 12" from a door E) full-height glass panels with a conforming crash bar F) glass opening less than 9 ft² in area

B, C, D Safety glazing is required in shower doors and glass panels less than 24" from a door if the lower edge of the glass is less than 60" from the floor. Glass panels where the sill is more than 18" above the floor do not have to be safety glazed. Glass panels with a conforming crash bar and glass panels less than 9 ft² do not require safety glazing.

In developing a signage system for a health care clinic, the designer decides that the room identification signs should be mounted perpendicular to the wall near the door to each room. Which of the following are of greatest concern in the design work? (Choose the four that apply.) A) the color of the lettering and background B) that the amount the Braille lettering is raised above the surface C) whether or not the width of the accessible route is reduced D) the mounting height to the center of the sign E) the use of standard ADA font F) whether or not the lettering is uppercase

B, C, D, F Barrier-free design requires that objects not protrude into the accessible path is such a way as to present a hazard. In addition, tactile signs must have a minimum 1/32" raised surface, and accessible routes must not be reduced in width. Room identification signs must be in uppercase. The color is not critical as long as their is contrast between the lettering and the background. Fonts must be san serif or simple serif, but there is not standard ADA font.

During the design development phase of planning a large classroom, which of the following methods could be used to reduce potential noise problems in a room of a given area whose exact shape has not yet been determined? (Choose the four that apply.) A) Design the room to have the largest ceiling surface area possible. B) Minimize the length of the wall separating the classroom from the noisiest adjacent room C) Plan to install sound-absorbent material on the walls of the classroom D) Study ways to increase the transmission loss of the room's partitions E) Specify a white noise system for the room F) Locate the doors to the classroom away from doors of nearby rooms.

B, C, D, F Options B, C, D, and F are all important considerations in controlling both noise within the room and noise being transmitted from outside a room. A large ceiling might be useful for applying sound-absorbent material, but the size of the ceiling is already determined as required by the program. A white noise system is useful for masking sounds in an office environment, but would not be appropriate in a classroom due to its cost and limited benefit in masking the types of noise in a classroom.

The interior designer can design details to accommodate building movement caused by which of the following forces? (Choose the three that apply.) A) building expansion B) floor deflection C) foundation settlement D) seismic events E) thermal expansion F) wind sway

B, D, F The interior designer can design partition slip joints for floor deflection, ceiling systems for seismic events, and mullion slip joints for wind sway. The architect or structural engineer must design movement joints for building expansion into the original building structure. Movement caused by foundation settlement and thermal expansion cannot be accommodated by interior design details.

Which test is MOST frequently used to evaluate carpet in the United States? A) flooring radiant panel test B) Steiner tunnel test C) mehanamine pill test D) methods of fire tests of building construction and materials

C All carpet manufactured or sold in the United States is required to pass the methanamine pill test. The flooring radiant panel test is used for corridor flooring and types of flooring in only a few occupancies. The Steiner tunnel test can be used, but it is not a realistic test on carpet because the material is tested on top of the tunnel.

If all of the following are present, what MUST be modified to achieve acoustic separation in a perimeter office? A) acoustical tiles B) gypsum wallboard C) convector D) batt insulation

C Although all of the listed options could be modified to improve acoustic separation, a convector is the most troublesome and must be modified or it will allow sound to travel through the vents in one office, through the opening around the convector pipe, and out the vents in the adjacent office.

With whom should the interior designer consult to determine where to locate free-standing stacks in a library? A) mechanical engineer B) library planner C) structural engineer D) fire protection designer

C Although all of these professionals may need to be consulted regarding book stacks, option C is the best choice. Because book stacks in libraries are very heavy, a structural engineer needs to determine if the existing floor is capable of supporting the weight. This would be the most important determining factor in early space planning and stack location. Issues of air supply, stack types, and sprinkler location could be based on the final locations of the stacks.

What is the purpose of construction element A in the following diagram of a wood floor? A) to minimize squeaking B) to prevent chemicals from the subfloor from contaminating the wood C) to act as a vapor barrier D) to provide added resiliency

C Although the sheet material indicated in the drawing may help minimize squeaking, the fact that a wood floor is shown over a concrete floor should indicate that the material shown is a vapor barrier.

The location of a private toilet room on the upper floors of a high-rise building is MOST limited by A) length of the hot and cold supply lines B) floor-to-floor dimensions C) distance from an existing drain D) plenum dimension

C Drain lines need a minimum slope to function properly. For example, a 3" drain line from a toilet would need a minimum slope of 1/8" per foot. The distance that the new toilet would be located from an existing drain would determine the total vertical distance needed to allow the drains to function correctly. Water supply lines can be any length. A single cold water line could be used with an instantaneous water heater at the sink, if necessary. Floor-to-floor height is not a limiting factor. The dimensions of the plenum space could limit the location of the drain needed to be incorporated totally within the plenum, but the ceiling below could be lowered slightly or a drain pipe could be furred in if necessary.

Which of the following strategies provides the MOST effective above-ceiling acoustical separation between two adjacent rooms, assuming all cracks between materials are suitable sealed? A) ceiling tiles with a high attenuation class (CAC) rating B) sheet lead draped from the slab above to the top of the ceiling tile C) partitions extended through the ceiling to the slab above D) framing suspended from the slab to the ceiling, with one layer of gypsum board attached on one side

C Extending the partition through the ceiling is the best method because it provides the most mass and fewest joints. Ceiling tiles with high CAC ratings do not provide the same sound attenuation as a partition. Using sheet lead may help a little, but sealing the joint between the suspended lead sheet and the top of the ceiling assembly is difficult and not always effective. Suspending framing with one layer of gypsum board also makes it difficult to seal the joint between the suspended elements and the top of the ceiling tiles. Further, one layer of gypsum board is not as effective as two layers.

An interior designer is developing plans for the ceiling in a 25,000 ft² corporate office. The program calls for the office space to consist of 70% closed offices and rooms and 30% open office space. The program has also specified that the operation of the company changes frequently, requiring rearrangement of personnel teams and project organization. Assuming a relocatable partition system is used, which type of ceiling system should the interior designer recommend to the client? A) custom track system B) 60" lay-in acoustical grid C) integrated ceiling system D) narrow bar exposed T-bar system

C Integrated ceiling systems are proprietary suspended systems designed to accommodate ceiling tile, lights, supply air devices, return air grilles, sprinklers, and other ceiling-mounted elements, as well as partition attachment. Such a system can easily provide for frequent changes in room configuration with accompanying changes in lighting and HVAC layout. Designing and manufacturing a custom track system would be very expensive and unnecessary for one job, as there are other available products. A 60" lay in acoustical grid would only work with a demountable partition system, and while such a system provides for changes, it is more expensive than an integrated ceiling system, which also provides for easy changes to mechanical and electrical components. A narrow bar exposed T-bar system is simply a type of grid system and does not make changes easier.

When coordinating with a security consultant, the interior designer's drawings should show A) a schedule of all security doors B) the emergency backup power supply C) the positioning of required lighting D) the wiring of the security devices

C Lighting locations are shown on the interior designer's reflected ceiling plans. All the other options listed would be on the electrical engineer's drawings or on the security consultant's drawings.

When visiting a job site, the interior designer notices that a handrail appears to be out of place. When measuring it, the designer finds the top of the handrail to be 39 1/2" above the nosing. In what direction and how far should the designer tell the contractor to move the handrail? A) up by 1/2" B) down by 1 1/2" C) down by 3 1/2" D) down by 6"

C The International Building Code (IBC) and accessibility requirements state that the handrails must be 34 to 38 inches high, as measured from the nosing. Moving the handrail down 3 1/2" and locating the top at the 36" position places it within the required limits and allows the contractor some tolerance in repositioning it. Moving it up by 1/2"to 40" would make the handrail too high. Although moving the handrail down 1 1/2" would technically place the handrail the acceptable position, the top of the handrail would be at the upper limit of the allowable measurements, and this placement would not allow for any misalignment or tolerance.

In order to specify an acceptable type of wall covering, which of the following tests should the designer require that the wall covering pass? A) methanamine pill test B) smoke density chamber test C) Steiner tunnel test D) vertical ignition test

C The Steiner tunnel test (ASTM E84) is used to measure the flammability of wall finishes and is the test most often required in building codes. The methenamine pill test is for carpet. The smoke density test does not measure flame spread, which is of vital importance. The vertical ignition test is for window coverings.

Based on previous projects, it is known that it costs about $45/f to construct a full-height partition. On the project now being budgeted, there are about 350 ft of this type of partition. If the contractor's overhead and profit are estimated to be 14%, how much should the interior designer budget for this line item? A) $15,120 B) $15,750 C) $17,950 D) $18,900

C The base cost of the partition is $45.00 per ft multiplied by 350 ft, or $15,750. To that, an additional 14% must be added. (350 ft) ($45/ft) = $15,750 ($15,750)(0.14) = $2205 $15,750 + $2205 = $17,955 ($17,950) For preliminary budgeting, amounts are often rounded off to the nearest $10 or $100.

In most situations, the appliations for a building permit is made by the A) building owner B) client C) contractor D) interior designer

C The contractor is the person typically responsible for submitting the plans and specifications to the building department, along with the application for permit.

Who is responsible for verifying that recessed down lights do not interfere with duct work shown on the mechanical plans? A) mechanical engineer B) electrical engineer C) interior designer D) architect

C The interior designer is ultimately responsible for coordinating the drawings of the various consultants

On a large commercial project, the location of telephone and computer outlets is determined by the A) building architect B) electrical engineer C) interior designer D) telecommunications consultant

C The interior designer uses information about the client's needs and requirements of the furniture systems to determine where telephone and data connections should be made. The building architect is not involved with these decisions. The electrical engineer and the telecommunications consultant are given the locations of various types of outlets by the interior designer, and then perform the necessary selection of wiring and sizing of conduit needed for the connections to central stations.

In a fully sprinklered office building, how many sprinklers would be required in a room measuring 20' x 25'? A) 2 spinklers B) 3 sprinklers C) 4 sprinklers D) 6 sprinklers

C The only way to locate sprinklers such that the maximum spacing between heads is 15' and the maximum spacing from the wals is 7 1/2' is to use four heads.

The final responsibility of awarding a contract rests with the A) interior designer B) construction manager C) owner D) owner's legal counsel

C The owner is ultimately responsible for deciding which contractor to award the contract to. The interior designer is generally involved but only assists with the process and gives advice.

When doing design work for remodeling toilet rooms to make them accessible, the designer finds that it is impossible to provide adequate clearance on one side of a door. What is the BEST course of action? A) propose to the client that walls be demolished and re-planned to provide the necessary clearances. B) Apply to the building department for a variance because of the remodeling problem C) Specify a power-assisted door opener that meets accessibility standards and incorporate this into the design D) Suggest that a unisex toilet be built nearby that complies with all accessibility requirements.

C The solution that is least expensive and most sensitive to accessibility requirements is to provide a power-assisted door opener.

An interior designer has recieved a construction cost estimate for an acoustical ceiling system. The area of the ceiling is 15,000 ft². The estimate is $6000 over the budget. The owner request that the currently specified 2 ft x 2 ft grid with tegular tiles be replaced with a less expensive system while maintaining acoustical qualities and a similar aesthetic. The contractor has provided pricing for alternative ceiling systems as shown in the matrix tegular tile 2x2 9/16 grid/ 5.00 unit cost standard tile 2x2 narrow grid/ 4.80 standard tile 2x2 standard T-bar/ 4.40 drywall with level 4 finish/ 4.20 standard tile 2x4 narrow grid/ 3.20 A) drywall with level 4 finish B) standard tile in 2 ft x 2 ft narrow grid C) standard tile in 2 ft x 2 ft standard T-bar D) standard tile in 2 ft x 4 ft narrow grid

C The standard tile in a 2 ft x 2 ft standard T-bar provides a similar aesthetic and reduces the cost enough to conform to the construction budget (15,000 ft² x $0.60 savings/ft²=$9000 savings). The cost for each system needs to be calculated to determine which alternative will reduce the price of the system by at least $6000. However, first the interior designer needs to identify which system(s) will meet the owner's requirement of maintaining the specified acousitcal performance and will provide a similar aesthetic. The draywall alternate clearly differs from the grid aesthetic and would not provide the sound-absorbing qualities of an acoustical tile ceiling, so this is an inappropriate choice. The 2 ft x 4 ft grid system would save the most money, but does not provide the same aesthetic as a 2 ft x 2 ft grid. The 2 ft x 2 ft narrow grid ceiling would comply with the acoustical performance requirements, but would only save $3000.

The three parts of a means of egress include the A) public way, exit, and exit access B) public way, exit access, and corridor C) exit access, exit, and exit discharge D) exit, exit enclosure, and exit discharge

C There are three parts to a building's means of egress, or exit path, which go from the least protected to the most protected. The exit access (e.g., room, aisle, hallway, or ramp) leads to the exit. Depending on occupancy and construction type, the exit access may or may not be protected. The exit (e.G., exterior exit door, exit enclosure for stairs, or exit passageway) provides a protected path of egress between the exit access and the exit discharge. It must always be protected by fire-resistance-rated construction The exit discharge (e.g., exterior exit stairway, exit court, or exterior exit balcony) is the portion of the egress system between the termination of the exit and a public way. The discharge must be unobstructed, sprinklered, and clearly visible from the exit termination point.

A designer is developing a space plan for a full floor tenant in a high-rise building. The designer needs to know which of the following to determine the maximum travel distance allowed by the IBC? A) construction type and height of the building B) occupancy classification and whether the design involves an exit or exit access C) occupancy classification and whether the building is sprinklered D) construction type and whether the building is sprinklered

C To determine the maximum travel distance (described in Sol 43) allowed by the International Building Code (IBC), the designer must know occupancy classification and whether or not the building is sprinklered. Travel distance is part of the exit access (described in Sol 40) and is usually not protected. Therefore, the IBC limits the distance occupants must cross to safely exit. The maximum allowable distance is greater in sprinklered buildings than in unsprinklered buildings.

When selecting and detailing window coverings for a building, what is the MOST important consideration to coordinate with the mechanical engineer? A) degree of transparency of the covering B) direction of airflow from the ceiling toward the window C) distance between the window and the window covering D) color of the window covering

C There should be at least 2" of space between the inside face of the glass and the window covering to avoid excessive heat buildup, which could cause the glass to crack or break. There should also be sufficient space at the top and bottom of the window covering to provide for air circulation to prevent heat buildup. The mechanical engineer should review and approve any window covering detail to verify that there is not a problem with the location of the window covering or its interaction with the type of glazing that has been specified for the building. Transparancy refers only to the amount of light coming through the window covering and does not have as much effect on the heat buildup as the space between the covering and the glass. The direction of airflow does not affect heat buildup, but it may affect the movement of the window covering when air is directed toward the window from a ceiling register. While the color of the window covering may affect heat buildup, it is not as critical a consideration as the spaces allowing for air circulation.

If a client asks the interior designer when it is permissible to move into a new space, the designer should tell the client that this can be done when A) the work is complete B) the AHJ field inspector gives approval C) the final inspection has been conducted D) a CO has been issued

D A certificate of occupancy (CO) is issued by the building department or the authority having jurisdiction (AHJ) after the final inspection has been conducted by the field inspector. A CO is sometimes also called a Use and Occupancy Certificate or a Letter of Occupancy. The client can only occupy the space after this document has been issued. Although the work must be complete, this is not sufficient to allow the client to move in. The field inspector must give approval, but this is also not sufficient until a final inspection is conducted and a CO is issued. Likewise, the final inspection is not sufficient until a CO is issued.

One of the primary advantages of a full wall schedule is that it A) takes less time to develop than a CPM chart B) is more detailed than a Gantt chart C) is large enough for several people to view at once D) involves the entire project team in the scheduling

D A full wall schedule is interactive and involves the entire project team--including the client--in the project scheduling. Each person on the project team places a card with time estimates for their associated tasks on the schedule. Then, the schedule serves as a starting point for discussion, as the cards can be moved around until everyone agrees on the project schedule. Once a schedule is set, it can be copied in smaller format for each project team member.

Which type of lighting would BEST enhance the appearance of a rough, plastered wall? A) fluorescent cove uplighting on all four sides of the room B) decorative chandeliers near the wall C) track lighting near the center of the room, aimed at the wall D) recessed incandescents close to the wall

D A grazing light from a point source close to the wall would best emphasize the wall's texture. The other types of lighting would appear to flatten the wall's surface.

An interior designer can determine what products an independent representative is handling by consulting A) the manufacturer's website B) a showroom directory C) Sweets Network Online D) a line chart

D A line chart lists the various products a representative handles.

What is the BEST way for an interior designer to ensure that the exact product desired will be used in the final design? A) showing the configuration of the product on the drawings and calling it out specifically B) writing a closed, descriptive specification C) requiring that the contractor submit samples of all items before purchasing them D) listing the information as a proprietary specification

D A proprietary specification calls out one single item by brand name, manufacturer, and model number and is the best way to ensure the exact product desired will be used in the final design. With a proprietary specification, the interior designer can also require that a sample be submitted to further verify that the item meets the project needs.

Which of the following provides the MOST accurate basis for estimating project costs? A) square footage B) functional units C) parameter D) quantity takeoff

D A quantity takeoff is the most detailed method of developing a budget, and therefore it is the most accurate. To use this method, count the actual quantities of materials and furnishings and multiply these quantities by firm, quoted costs.

When the interior designer is providing services using AIA Document B153, Standard Form of Agreement Between Owner and Architect for Furniture, Furnishings and Equipment Design Services, who is responsible for final acceptance of furniture delivery? A) furniture dealer B) installer C) interior designer D) owner

D AIA Document B153 specifically states that the owner, as the buyer of the goods, receives, inspects, and accepts or rejects furniture, furnishings, and equipment at the time of delivery to the point of use.

Most building codes in the United States are established by A) federal laws B) model code-writing agencies C) state governments D) local governments

D Any rights not specifically reserved for the federal government by the U.S. Constitution revert to the individual states. The states, in turn, can delegate control of construction to local jurisdictions. Only a few states have state building code. In nearly all cases, the local or state code is based on the International Building Code (IBC) or one of the model codes.

An interior designer recommends a particular vinyl wallcovering to a client after being told by a sales representative that the product can be cleaned using only a damp sponge. The manufacturer also states this in its product literature. After installing the product, the client finds that some soiling cannot be cleaned off with just water, and harsher chemicals must be used instead. Under which of the following can the interior designer claim that the sales representative's company and manufacturer are liable? A) warranty of merchantability B) implied warranty of fitness C) warranty of title D) express warranty

D Because the cleaning quality of the wallcovering is clearly stated in the product literature and the same was stated by the sales rep, the manufacturer and representative have created an express warranty that the product will perform in a specific way. A warranty of merchantability is an implied promise by a merchant, or someone in the business of selling something, that what they are selling is fit for the ordinary purposes for which such goods are used. An implied warranty of fitness title means that the seller has ownership of a product an can legally sell it to others.

To verify a manufacturer's claim that its product has met the requirements of an ASTM standard, the interior designer should A) contact the relevant trade association for the product B) contact ASTM and get a copy of the standard C) investigate the standard on internet sites D) request detailed information from the manufacturer

D If a product has been tested according to ASTM standards or otherwise meets ASTM requirements, then the manufacturer should have the test results or other backup information and be willing to send that information to the designer on request.

Thermostat locations are determined by the A) architect B) electrical engineer C) HVAC contractor D) mechanical engineer

D In addition to designing the HVAC system, the mechanical engineer determines the best locations for controls such as thermostats. When these locations interfere with other wall-mounted items, the interior designer may sometimes suggest minor modifications.

What is the SAFEST type of glazing to use in a sidelight adjacent to a door? A) ceramic B) wire C) float D) tempered

D Neither options Bor C is correct, because wire and float glass, which do not meet the requirements of either ANSI Z97.1 or 16 CFR Part 1201, are not considered safety glazing. Option A is also incorrect. Although there are some types of laminated ceramic glazing that meet the requirements, most are not considered safety glazing.

What type of system would be MOST appropriate in a large commercial remodeling project where a decorative acoustical ceiling and plenum are required? A) integrated B) linear metal strip C) gypsum wall board D) concealed spline

D Plenum access precludes the use of gypsum wallboard ceiling unless many access panels were used, which is costly and can become unsightly with use. Both integrated ceilings and linear metal strip ceilings provide for some access, but their cost in a large commercial project would not be warranted. An integrated ceiling may be a good choice, but the question does not give enough information about the parameters of the problem to make this a reasonable option.

A client has approached an interior designer to remodel a large mansion into a restaurant and nightclub. Before accepting the commission or beginning any work, with whom should the designer consult? A) building department B) city planning commission C) department of excise D) zoning department

D Remodeling the building from a residence to a restaurant involves a change in use, which is regulated by the zoning department. If the mansion is in a zoning district that does not allow business uses, the project would either not be feasible or require that the owner apply for a variance. Neither the building department nor the city planning commission regulates changes in use. The department of excise is concerned with tax issues, not building issues.

A building that carries a gold rating has been designated and certified under which of the following sypstems? A) Greenguard B) Green Seal C) ISO 14000 D) LEED

D The LEED rating systems are green building certification guidelines developed by the U.S. Green Building Council (USGBC). There are five levels of certification (effort, certified, silver, gold, and platinum) set forth in the Green Business Certification Inc. (GBCI, formerly the Green Building Certification Institute) rating systems. Options A and B are incorrect because Greenguard and Green Seal are both product-rating systems. Greenguard certifies for acceptable emission levels, while Green Seal certifies products that meet certain environmental standards. Option C is incorrect because ISO 14000 refers to the International Standards Organization's collection of standards and guidelines that relate to a variety of environmental standards, including labeling, life-cycle assessment, and others. ISO standards are used to measure the performance of other organizations that certify products' other environmental claims.

The client is MOST typically involved with procurement of furniture through A) the acknowledgement B) the freight bill C) a purchase order D) a sales agreement

D The client must sign the sales agreement, which obligates the client to pay for the purchase of merchandise. The other documents are handled by the interior designer, dealership, or others.

In designing a new space, the interior designer can influence life safety the MOST by coordinating with consultants concerning A) compartmentation B) fire detection C) smoke control D) sprinklers

D The interior designer would most likely be able to influence the design of sprinklers by coordinating with the mechanical or fire protection engineer during the construction documents phase of a project. For example, the interior designer could request that sprinklers be placed in certain positions or that additional sprinklers be installed. Compartmentation and smoke control are already designed by the architect and mechanical engineer in the original plans of the building, and there would be little the designer could do to change these elements. Fire detection is determined by the local building code and the type of building occupancy, so little influence by the designer is possible.

Who is responsible for determining the location and general condition of existing light fixtures as part of a due diligence investigation? A) electrical engineer B) electrical subcontractor C) general contractor D) interior designer

D The location and general condition of existing light fixtures requires no electrical expertise, and these can be verified by the interior designer. However, such things as the capacity of wiring, the condition of wiring, and the safety of the fixtures must be determined by the electrical engineer or a qualified electrician.

In which building type are fire-resistive construction requirements likely to be LEAST restrictive? A) Type I B) Type II C) Type III D) Type IV

D The most restrictive building type is Type I, while the least restrictive is Type V.

The two MOST important factors in determining the number of exits required for a particular room or space are the A) occupancy and the distance from the room exit to the building exit B) exit width and the common path of egress travel C) occupancy load and the building size D) occupancy and the occupant load

D The occupancy and occupant load are used to determine the number of exits.

When working under the requirement of the International Energy Conservation Code (IECC), the interior designer will MOST likely use which method to assist in the lighting design of a commercial project? A) building area method B) energy cost budget method C) luminaire efficacy method D) space-by-space method

D Using the space-by-space method, an LPD in W/ft² is assigned by the IECC for various types of spaces. This value is multiplied by the area of the space under consideration to arrive at the total allowable power that can be used for lighting that space. Knowing this value will assist the designer in selecting lamp and luminaire types to meet the illumination requirements of the space while keeping within the power budget. Because there are many individual space types given in the IECC, the designer would most likely use this method to meet the specific illumination requirements of each space. Further, this method allows for tradeoffs, so if less power is required or used for one space, the extra power unused in one area can be transferred to the allowance for another space. The building area method for developing lighting power densities (LPDs) uses an LPD for a general building type, which is then multiplied by the total area of the building to get the total allowable power that can be used for the building. It would probably not be use by an interior designer to design just a portion of a larger building. The energy cost budget method is more complex way to determine the total energy budget for an entire building using computer simulation or hourly energy use over the course of a year. It is not appropriate for the interior design of specific spaces. The luminaire efficacy method is incorrect because there is not such method.

Who would be responsible for ordering and replacing a stone top of a custom built reception desk that includes woodwork, stone, metal, and a light fixture? A) architect B) interior designer C) stone fabricator D) woodwork fabricator

D For custom-designed woodwork, the woodwork fabricator orders minor accessory materials such as stone, metal, and glass from other suppliers, and incorporates them into the woodwork.

In the partition of a shower stall shown in the illustration, drag the material labels from the right into the boxes on the section detail. Some labels will not be used. cove base welded wire fabric waterproof membrane drain grout metal lath cement mortar crushed stone ceramic tile

cove base grout cement mortar welded wire fabric waterproof membrane crushed stone The section shows a typical full-mortar bed installation of ceramic tile that slopes to a drain. The waterproofing membrane is placed over the concrete slab, and a full mortar bed of portland cement, reinforced with welded wire fabric, is then place on top to serve as a base for the ceramic tile. The tile joints are filled with grout. Crushed stone is placed next to the drain to prevent mortar from filling the perforations in the side of the drain. A cove base tile is used to ease the transition between the floor and the wall to make cleaning easier.
