Question 1

With whom should the interior designer consult to determine where to locate freestanding stacks in a library?

(A) mechanical engineer
(B) library planner
(C) structural engineer
(D) fire protection designer

Answer 1

(C) structural engineer

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 locations could be based on the final locations of stacks.

Question 2

In specifying new window coverings and tracks to replace building-standard windowcoverings, 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 change 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

Answer 2

(A) verifying that the building owner approves of the change in the building’s exterior
appearance
(C) determining if the mechanical engineer objects to the replacement plans
(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

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 crackling 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 cleint’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 patter can be found.

Question 3

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

Answer 3

(D) sprinklers

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 architectu and mechanical engineer in the original plans of the building, and there would be little to the designer could do to change these elements. Fire dectection is determined by the designer is possible.

(D) interior designer

Answer 10

(D) interior designer

The location and general condition of existing light fixtures requires no electrical expertisem and these can be verified by the ID. 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.

Question 11

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

Answer 11

(B) CPM chart

The critical path method (CPM) uses a network diagram that shows all tasks required to complete a project. From the CPM chart, a path of the critical tasks defines the sequence 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 tradeoffs.

The program evaluation review technique (commonly referred to as a PERT chart) is similar to CPM method, but uses different networking methods. PERT charts are no commonly used with complext projects because CPM charts better show critical tasks and their associated times.

A bar chart (Gantt chart) is a simpler representation of a schedule and does not show a critical path.

Question 12

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

Answer 12

(D) involves the entire project team in the scheduling

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 removed 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.

(A) giving the electrical engineer information about the client’s equipment
(B) providing the mechanical engineer with the occupant load for each space
(D) making sure that the final drawings and specifications are coordinated
(F) giving the electrical engineer the designer’s preferred choices for luminaires

The ID 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 ID also has overall responsibility for making sure all consultants’ documents are coordinated with teh ID documents.

The mech engineer (or fire protection engineer, if there is a separate consultant) is the person responsible for staying current with all code requirements in the projects jurisdiction. The location of the electrical closets is predetermined by the building architect, not the ID.

(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.

Answer 70

(B) There is not enough space above the ceiling.

Question 71

Which of the following strategies provides the MOST effective above-ceiling acoustical separation between two adjacent rooms, assuming all cracks between materials are suitably sealed?

(A) ceiling tiles with a high ceiling 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

Answer 71

(C) partitions extended through the ceiling to the slab above

Question 72

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

Answer 72

(B) mechanical

Question 73

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

Answer 73

(B) color rendering index

Question 74

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

Answer 74

(D) a CO has been issued

Question 75

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 dose to the wall

Answer 75

(D) recessed incandescents dose to the wall

Question 76

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

Answer 76

(A) flat plate

Flat plate construction consists of a single thickness of reinforced concrete supported by concrete 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 waffie slab systems occupy much more space than a flat plate slab and would require a lower finished ceiling height after services are installed.

Question 77

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

Answer 77

(B) door coordinator

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 dose one leaf of the pair of doors before the leaf with the attached astragal closes. This is to prevent incomplete dosing 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.

Question 78

Which of the following are found in the project manual? (Choose the four that apply.)

(A) performance bond
(B) testing requirements
(C) instructions to bidders
(D) cost estimate
(E) Owner-Interior Designer Agreement
(F) supplementary conditions

Answer 78

(A) performance bond
(B) testing requirements
(C) instructions to bidders
(F) supplementary conditions

Question 79

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 in a proprietary specification

Answer 79

(D) listing the information in a proprietary specification

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.

Question 80

When the interior designer is providing services using AIA Document B153, Standard Form of Agreement Between Owner and Architect for Furniture, Furnishings and Equipment Designer Services, who is responsible for final acceptance of furniture delivery?

(A) furniture dealer
(B) installer
(C) interior designer
(D) owner

Answer 80

(D) owner

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.

Question 81

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.

Answer 81

(A) The client could avoid the contractor’s markup.

Because general contractors add their overhead and profit charges
(anywhere from about 10% to 20%) to all subcontracted work, the client 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 could, without the contractor’s markup.

Question 82

Based on previous projects, it is known that it costs about $45/ft to construct a fullheight 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

Answer 82

(C) $17,950

The base cost of the partition is $45.00 per ft multipied by 350 ft,
or $15,750. To that, an additional 14% must be added.

For preliminary budgeting, amounts are often rounded off to the nearest $10 or $100.

Question 83

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 targeted for that city
(D) interior designers and architects who practice in that city and design projects of a similar type

Answer 83

(B) a local contractor who builds projects of a similar type

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.

Question 84

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

Answer 84

(D) express warranty

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 requires that something sold must be suitable for the intended purpose. A warranty of title means that the seller has ownership of a product and can legally sell it to others.

Question 85

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

Answer 85

(B) furnishings, professional fees, taxes, and telephone installation

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.

Question 86

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

ref question 86

Answer 86

(C) to act as a vapor barrier

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.

Question 87

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 thick-set installation
(C) a ½ in (12 mm) layer of mortar with the stone dry-set on top
(D) a standard thin-set installation

Answer 87

(A) a thick-set application using a cleavage membrane

Because slate does not have a uniform thickness and a concrete
subfloor above grade may deflect and cause cracking, the best installation is a thickset 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.

Question 88

A 216 pitch carpet has

(A) a pile height that is almost ¼ in ( 6 mm) high
(B) 8 surface yarns per inch (25 mm)
(C) an equivalent gauge of 1/6
(D) a commercial-grade stitch rate

Answer 88

(B) 8 surface yarns per inch (25 mm)

Pitch is the number of ends of surface yarn in a 27 in (686 mm)
width. To convert this measurement to gauge (the spacing between stitches), divide 27 in (686 mm) into 216 stitches. This gives 8 stitches/in, or 8 surface yarns/in. The equivalent gauge, therefore, is 1/8.

Question 89

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) luninaire efficacy

Answer 89

(A) coefficient of utilization

The coefficient of utilization (commonly abbreviated “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.

Question 90

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

Answer 90

(B) furniture dealer

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.

Question 91

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

Answer 91

(D) request detailed information from the manufacturer

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.

Question 92

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

Answer 92

(D) a line chart

A line chart lists the various products a representative handles

Question 93

The client is MOST typically involved with procurement of furniture through

(A) the acknowledgment
(B) the freight bill
(C) a purchase order
(D) a sales agreement

Answer 93

(D) a sales agreement

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.

Question 94

What testing standard should be specified for the durability of office chair construction?

(A) ANSI/BIFMA X5. l
(B) ASTM D4157
(C) CAL TB133
(D) NFPA 701

Answer 94

(A) ANSI/BIFMA X5. l

ASTM D4157 is the Wyzenbeek abrasion resistance 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.

Question 95

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

Answer 95

(B) drop ship order

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.

Question 96

An interior designer has received a construction cost estimate for an acoustical ceiling system. The area of the ceiling is 15,000 ft2 (1394 m2). The estimate is $6000 over the budget. The owner requests that the currently specified 2 ftx 2 ft (610 mmx 610 mm) 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.

ref q 96 for matrix

Based on this pricing information and knowledge of the acoustical properties of eachof these types of assemblies, which alternate system should the interior designer recommend to the client?

(A) drywall with level 4 finish
(B) standard tile in 2 ftx2 ft (610 mmx610 mm) narrow grid
(C) standard tile in 2 ftx 2 ft (610 mm x 610 mm) standard T-bar
(D) standard tile in 2 ftx4 ft (610 mmx 1220 mm) narrow grid

Answer 96

(C) standard tile in 2 ftx 2 ft (610 mm x 610 mm) standard T-bar

The standard tile in a 2 ft x 2 ft ( 610 mm x 610 mm) standard
T-bar grid 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 acoustical performance and will provide a similar aesthetic. The drywallalternate clearly differs from the grid aesthetic and would not provide the soundabsorbing qualities of an acoustical tile ceiling, so this is an inappropriate choice.

The 2 ftx4 ft (610 mmx 1220 mm) grid system would save the most money, but does not provide the same aesthetic as a 2 ftx2 ft (610 mmx610 mm) grid. The 2 ft x 2 ft ( 610 mm x 610 mm) narrow grid ceiling would comply with the acoustical performance requirements, but would only save $3000 (15,000 ft2 x $0.20 savings/ ft2= $3000 savings)

Question 97

ref q 97 for image on pg 88

Answer 97

ref pg 131 for answer

Question 98

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

Answer 98

(A) acknowledgment

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.

Question 99

An interior designer is developing plans for the ceiling in a 25,000 ft2 (2323 m2) 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 organizations. 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 in (1524 mm) lay-in acoustical grid
(C) integrated ceiling system
(D) narrow bar exposed T-bar system

Answer 99

(C) integrated ceiling system

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 in (1524 mm) layin acoustical grid would only work with a demountable partitions system, and while such a system provides for changes, it is more expensive that 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.

Question 100

Which of the following provides the MOST accurate basis for estimating project costs?

(A) square footage
(B) functional unit
(C) parameter
(D) quantity takeoff

Answer 100

(D) quantity takeoff

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.

Question 101

Which of the following is the interior designer’s BEST source for determining a piece of furniture’s net price?

(A) showroom manager
(B) manufacturer’s price list
(C) furniture dealership
(D) representative’s line chart

Answer 101

(C) furniture dealership

Net price is the final cost after all discounts and any other price
adjustments are done by the furniture dealership. The manufacturer’s price list or a showroom manager could provide a price for the furniture, but the price would not include discounts or other price adjustments. Therefore, the interior designer’s best option for determining the net price is the furniture dealership. Line charts have nothing to do with prices.
