IDPX Sample Test 2QUESTIONS AND CORRECT ANSWERS 2022

IDPX Sample Test 2QUESTIONS AND CORRECT ANSWERS 2022An interior designer would be MOST likely to suggest to a mechanical engineer that additional ventilation or exhaust be provided to a(n) A) private toilet room B) commercial kitchen C) corporate conference room D) exercise room in a community recreation center C. corporate conference room An interior designer would have knowledge about the conference room's intended use and may be in a position to suggest to the mechanical engineer that additional ventilation or exhaust is necessary. In options A, B, and D, the ventilation and exhaust requirements are governed by local building codes, and the interior designer is unlikely to know of any reason to increase them that is not also evident to the engineer. The "latest possible starting time" is found in which of the following schedules or charts? A) CPM chart B) full-wall schedule C) Gantt chart D) workflow schedule A. CPM chart A critical path method (CPM) chart graphically depicts all the tasks required to complete a project, the sequence in which they must occur, and their duration. As the name implies, the chart determines which tasks and durations are the most critical to be completed on schedule if the entire project is to be completed on time. Other tasks may start and finish a little earlier or later without affecting the final completion date. Thus, a task could have a "latest possible starting time" attached to it. A full-wall schedule is a manual way of scheduling using 3 in x 5 in cards on a wall; each card lists needed tasks and includes a timeline across the top and names of people completing the tasks along the left side. A Gantt chart is another name for a bar chart; it uses horizontal bars to indicate the duration of tasks coordinated, and includes a timeline across the top and the individual tasks listed along the left side. A workflow schedule is not a type of chart used in the interior design profession. Which of the following provides the MOST accurate basis for estimating project costs? A) square footage B) functional unit C) parameter D) quantity takeoff D. quantity takeoff A quantity takeoff is the most detailed method of developing a budget and, therefore, is the most accurate. To use this method, count the actual quantities of materials and furnishings and multiply these quantities by firm, quoted costs. The MOST important source of information for monitoring project budgeting during design and development of construction documents is the A) aged accounts receivable report B) fee projection report C) project progress report D) personnel timesheet D. personnel timesheet Each individual staff member's timesheet provides the basis for developing the project progress report (or a simple manually produced graph) that is used for monitoring a project. The aged accounts receivable report shows the status of all invoices for all projects and whether they have been paid or not. It has nothing to do with monitoring an individual project for comparison with the budgeted time and fees. A fee projection chart is necessary for comparing actual time and fees expended, but by itself is not a basic source of information. A project progress report does compare actual time and fees with budgeted time and fees for a project, but it is no the source of the information. When an interior designer is coordinating with an acoustical consultant, the designer's drawings should show A) copies of the consultant's sound control diagrams B) a schedule of STC ratings for all partitions C) the consultant's specifications for equipment D) construction details of critical acoustical elements D. construction details of critical acoustical elements Acoustical consultants rarely produce separate drawings like those of an electrical or mechanical engineer. However, they do suggest details and diagrams critical for sound and noise control. These details and diagrams are redrawn (not copied) by the interior designer and placed on the designer's drawings (or, if they are CAD details, they are reproduced directly). Schedules of sound transmission class (STC) ratings are not used. Any specifications the consultant provides are placed in the project manual and not on the drawings. A project manager is completing the due diligence site analysis for a building to be used by a law firm. Before beginning space planning, the project manager is MOST likely to need expert consulting assistance to determine the A) type of in-floor electrical and communication outlets B) number and locations of sprinkler heads C) reinforcement needed to accommodate a new library D) amount of additional natural lighting needed for daylighting C. reinforcement needed to accommodate a new library The additional dead load of a new library could be significant enough to require extra structural reinforcement. The project manager would require the assistance of a structural engineer to determine this. Without the assistance of a consultant, the project manager could determine the number and locations of sprinkler heads, whether the natural lighting is sufficient for daylighting, and the type of in-floor electrical and communications outlets that are needed. (However, the capacity of the electrical system for additional or unusual loading would have to be determined by an electrical engineer.) An interior designer is teaming with an architect and working under the architect's contract with the owner to complete a new hotel project. The owner for the project will be using a construction manager as adviser (CMa) as part of the project team using AIA Document A232, General Conditions of the Contract for Construction, Construction Manager as Adviser Edition. What assistance can the interior designer expect the construction manager to provide to the interior designer? A) recommendations for selection of contractors and furniture dealers B) advice on construct-ability, cost estimating, and project scheduling C) assistance with fast-track design procedures and construction methods D) participation in construction administration and project closeout B. advice on construct-ability, cost estimating, and project scheduling The interior designer can expect the construction manager to provide early advice on construct-ability, cost, and scheduling. A CMa works with the owner and architect in selecting contractors, but does not recommend furniture dealers. While a CMa does assist with fast-track construction, there is no mention of using this delivery method in the question. The CMa does participate in construction administration and project closeout, but in this scenario, the architect would be involved with these activities under the A232 document, with the interior designer as a secondary participant. Before preparing construction documents, the interior designer should verify whether any particular types of lighting fixtures are required by coordinating with the A) architect B) building owner C) contractor D) electrical engineer B. building owner The building owner may specify the types of light fixtures to used in the building. If so, this specification should be stated in the contract documents. Therefore, the interior designer should check with the building owner before preparing the documents. The construction fit-out allowance provided to a tenant in an office building would be defined in the A) BOMA standards B) lease agreement C) rental contract D) work letter D. work letter A work letter is part of the lease agreement between a tenant and the owner of a commercial space and defines, among other things, what basic allowances for interior construction the tenant will receive as part of the cost of the lease. These include an allowable number of linear feet of standard partitions, an allowable number of doors and light fixtures, and similar basics required for building out the tenant space. A work letter may also provide for giving the tenant a lump sum amount in lieu of specific quantities of construction elements so the tenant can use the allocated amount, and additional tenant money if required, to build out the tenant's space. The Building Owner and Managers Association (BOMA) standards give detailed procedures for measuring leased space in commercial buildings. These may be part of the lease agreement, but do not state what allowances are given to a tenant. The lease agreement is the contract between the tenant and the building owner (or manager) and includes rental rates, regulations, other legal dtails of leasing space, and the work letter. "Rental contract" is not a term normally used in the industry, but such a document would be the same as a lease agreement. What contractor selection method would be BEST for a client who wants to get the lowest price for remodeling a complex data-processing facility? A) stating the requirements of the project in an advertisement for bidders in the local trade journals and newspapers B) selecting a qualified contractor and negotiating a fixed cost based on detailed drawings and specifications C) negotiating the lowest possible price with one contractor and then bidding the project if the first cost is over the client's budget D) developing a list of contractors who have experience in the project type and then asking them to bid on the job D. developing a list of contractors who have experience in the project type and then asking them to bid on the job. The best way to get the lowest price is to open the project for bidding, so this eliminates B and C. Because the project is a specialized building type, it would be best to use only prequalified bidders who have had experience with data-processing facilities. This leaves option D as the best choice. The MOST appropriate time to determine the exact requirements for grab bars in a building's toilet rooms is during which project phase? A) programming B) schematic design C) design development D) construction drawing development C. design development Only broad planning issues related to barrier-free design need to be made during the early phases of programming and schematic design. While the decisions about detailed items, like the locations of grab bars, can be made during the construction documents phase, it is better if they have been settled before construction drawings are begun. During preliminary planning for a day care center in a low-rise office building, the interior designer discovers that the zoning ordinance limits the area of such centers to about 20% less than the client's programmed needs. How could the interior designer best attempt to resolve the problem? A) apply for a conditional use permit B) suggest the client apply for a variance C) reduce the area planned to that allowed D) appeal to the local planning commission B. A variance is a deviation from zoning regulations. The interior designer could assist the client in applying for a variance and present the case to the zoning board. In the case of a day care center requesting a relatively small size increase, it is likely that the hardship would be recognized and a variance granted. A conditional use permit is typically used to allow a nonconforming use in a zoning district and would not be appropriate way to solve the problem. It is unlikely that the client would want to decrease the size of the planned center. The local planning commission would not be involved with this kind of issue. A designer is planning a library in which tall bookshelves will be used. If the project is located in a city that has adopted the International Building Code (IBC), where would the designer look to find requirements on the minimum allowable space between the top of the shelving and the sprinkler heads in the ceiling? A) IBC B) International Mechanical Code C) NFPA 13 D) IPC C. NFPA 13 The IBC refers to NFPA 13 in detailing the requirements of sprinkler system design and installation. The other model codes refer to NFPA 13 as well. Where are flame-spread ratings in a building MOST restrictive? A) in exit enclosures B) on corridor floors C) in access ways to exits D) in enclosed spaces A. in exit enclosures Exit enclosures, such as stairways and exit passageways, are the most critical part of the egress system. Therefore, they must have the most restrictive flame-spread ratings. An interior designer is calculating the lease area for an office occupying a portion of a high-rise building using the Building Owners and Managers Association (BOMA) standard ANSI/BOMA Z65.1, Office Buildings: Standard Methods of Measurement. The exterior wall includes 65% glass area. The designer should calculate the area of the interior space by measuring to the A) inside surface of the exterior wall B) inside glass surface C) outside glass surface D) center-line of the exterior wall B. inside glass surface According to the ANSI/BOMA Z65.1, when the glass is more than 50% of the exterior wall, the measurement is taken to the inside surface of the glass. If the glass is less than 50% of the exterior wall, the measurement should be taken to the inside surface of the exterior wall. The outside glass surface and center-line of the exterior wall are never used as points of measurement. When selecting interior partition finishes to meet flame-spread standards, the MOST important considerations are A) the occupancy group and location in the building where the finishes will be used B) whether or not the building has an automatic sprinkler system and the construction type C) whether or not the partition is a fire barrier and the ratings of assemblies in the partition D) the hour rating of the partition on which the finish will be installed and the construction type A. the occupancy group and the location in the building where the finishes will be used Building codes limit flammability of finishes based on the occupancy of the building and whether the finishes are in an exit or not. A sprinkler system may allow a reduction in one flame-spread class rating but is not the over-riding variable. Flame-spread requirements are also independent of the ratings of the assembly on which the finishes are placed. The following abbreviated table includes requirements for occupancy loads. A restaurant on the ground floor contains 3500 ft² of dining area, a 1000 ft² kitchen, and a 1200 ft² bar. What is the total occupant load: use load factor assembly areas, concentrated use 7 assembly areas, less concentrated 15 hotels and apartments 200 kitchens, commercial 200 offices 100 stores, ground floor 30 A) 202 occupants B) 318 occupants C) 380 occupants D) 410 occupants B. 318 occupants From the table, assembly areas including restaurants and bars have an occupant load of 15 ft² per occupant. Commercial kitchens have an occupant load of 200 ft² per occupant. Therefore, 3500 ft²/15 ft²/occupant = 233 occupants 1000 ft²/200 ft²/occupant = 5 occupants 1200 ft²/15 ft²/occupant = 80 occupants total = 233 + 5 + 80 = 318 occupants Working under the IBC, a designer has calculated that a total exit width of 8 ft is required from a store. What combination of door widths would meet most exiting requirements? A) one 26 in door remotely located from a pair of 34 in doors B) a pair of 32 in doors remotely located from one 38 in door C) three 34 in doors remotely located D) three 36 in doors remotely located D. three 36 in doors remotely located Options A, B, and C include doors that would provide less than a clear 32 in wide opening. The interior designer can find the requirements for the maximum flow rates for plumbing fixtures for a project by consulting which of the following? A) authority having jurisdiction (AHJ) B) International Green Construction Code C) International Plumbing Code D) WaterSense Program of the Environmental Protection Agency (EPA) A. AHJ To determine the maximum flow rates for a specific project, the interior designer must obtain this information from the local AHJ, as many states and local jurisdictions have established requirements that differ from those in other codes and standards, including the International Plumbing Code. The International Green Construction Code provides both mandatory and voluntary standards for water use, but applies only if it has been adopted by the local jurisdiction. The International Plumbing Code gives maximum flow rates for various types of plumbing fixtures, but can be superseded by the local AHJ. The WaterSense program is a voluntary program that certifies products that use 20% less water than the federal minimum established by the U.S. Energy Policy Act of 1992 without sacrificing performance. In a 90,000 ft², single-story office building, what would be of greatest concern in space planning? A) dead-end corridors B) corridor widths C) horizontal exits D) travel distances D. travel distances A 90,000 ft² building would be approximately 300 ft on a side or about 250 ft wide and 360 ft long. The size combined with typical rectangular planning of corridors would create very long distances to exits. An interior designer's client wants to remodel a one-story office building into a restaurant and nightclub. Under the IBC, the life safety of the building that will require the MOST significant change is the A) number and location of smoke detectors B) capacity of the sprinkler system C) size and number of exits D) addition of smoke control system C. size and number of exits With a change of occupancy from an office that was origianlly a B occupancy designed using an occupant load of 100 ft² per occupant to an assembly occupancy, A, with an occupant load of 5 ft² (standing space for a nightclub) to 15 ft² per occupant (for restaurant with tables and chairs), the size of exits will have to be enlarged to accommodate more people. This could require major changes to the size and possible the number and location of exits. While additional smoke detectors and their precise locations are important, they do not represent a significant change to the building. Both offices and restaurants are considered light hazard occupancies for the purpose of designing the sprinkler system, so the overall capacity would not be affected, just the exact location of sprinkler heads once the floor plan is established. For a one-story building of assembly occupancy, a smoke control system is not needed, as it is in a large high-rise building or a building with an atrium. Which of the following statements are true about fire-rated door assemblies? (Choose the four that apply.) A) Either hinges or rated pivots may be used. B) Glass area is limited based on rating C) Under some circumstances, a closer is not needed. D) Doors must be hollow metal type. E) Ball bearing steel hinges are required F) Labeling is required for both door and frame. A, B, E, F Either hinges or rated pivots may be use, glass area is limited based on rating, ball bearing steel hinges are required, and labeling is required for both door and frame. Closers are always required for fire-rated door assemblies (protected openings). While doors with higher fire ratings (greater than 1 hour) are generally hollow metal, wood doors are available with fire ratings of less than 90 minutes. When considering the initial space planning of an accessible toilet room, which of the following design elements should be of MOST concern? A) door swing and toilet position B) grab bar location and approach dimension C) stall depth and approach dimension D) door swing and approach dimension D. door swing and approach dimension The size of accessible stalls, whether standard or end-of row type, is fixed. Factors that could affect the total space required would be use of an in-swing door (which adds to the area required) and whether the design uses a side or front approach (latch side takes the least room). Grab bar locations and toilet position relative to the stall are fixed and would not be of initial concern. In the detail show which dimension of the transition strip needs to be changed to meet accessibility requirements? A) 3/8" B) 3/4" C) 1" D) 4" D. 4" The 4 inch dimension needs to be changed. The 3/8 in carpet pile height leaves a vertical change in level of 5/8", which must be accommodated with a ramp slope of 1:12. Either the height of the leading edge of the transition strip needs to be increased or the width of the sloped portion of the strip needs to be widened. Increasing the height of the leading edge of the trasition strip to 5/8" with a 3/8" pile height results in an acceptalb e1/4" vertical change of level from the top of the carpet to the strip, leaving a distance to the top of the wood floor of 3/8". However this is unrealistic because the carpet will be crushed under the weight of a wheelchair, effectively making the vertical change in level greater than 1/4". If the 3/8" in dimension remains unchanged in order to create a slope of 1:12, the width of the strip has to be widened from 4 in to 7 1/2" to creat a 1:12 slope. 5/8" x 12 = 7 1/2" The 3/4" dimension is horizontal and has nothing to do with accessibility. The 1" dimension is fixed by tht thickness of the wood floor. While the Americans with Disabilities ACt (ADA) allows for a change of level up to 1/2", with a 1/4" being vertical and 1/4" having a slope of 1:2, this approach is not possible with the given thickness of the carpet and the wood floor. What are the MOST important design elements to incorporate into a hotel to provide safe egress for physically disabled people? A) visual alarms and audible alarms B) visual alarms and flashing smoke detectors C) audible alarms and large emergency lettering D)audible alarms and tactile signage A. Emergency warning systems mush provide both visual and audible alarms. Based on ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, which method is the MOST direct and easist to use to determine the maximum allowable lighting power density (LPD)? A) space-by-space method B) lighting system method C) building area method D) energy cost budget method C. building area method The building area method gives the maximum allowed power is Watts per square foot of buildings area based on the building type. The power per square foot is multiplied by the gross floor area of the building to determine the LPD. This is the most direct way to determine the LPD. The space-by-space method requires the interior designer to determine the gross area of each space type in a project and multiply that by the allowable wattage per square foot. There is no such method as the lighting system method. The energy cost budget method requires a computer simulation, which is the most complex of the given methods. During space planning, the designer must locate a 36" door leading from a corridor, where limited space is available, into another room. One option is to orient the corridor either perpendicular or parallel to the wall separating the corridor from the room and to swing the door in any direction. The door will have a latch only, with no closer. In order to provide for accessibility and minimize the width of the corridor, which of the following door orientations and approach directions would BEST meet the criteria? A) front approach, door swings into room B) latch side approach, door swings into corridor C) hinge side approach, door swings into room D) front approach, door swings into corridor C. hinge side approach, door swings into room Looking at the required maneuvering clearances shown in the illustrations, it is clear that the side approach with the door swinging into the room only requires a minimum of 42" (assuming the door has no closer). This would allow the use of a 44" minimum corrodor. The front approach (door swings into room) and latch side approach (door swings into corridor) both require a minimum of 48". The front approach (door swings into corridor) would require a 60" corridor (a 36" door plus 24" of side clearance. Which of the following are the MOST effective strategies for maximizing indoor air quality? (Choose the four that apply.) A) conducting a post-occupancy evaluation B) developing a maintenance manual C) maximizing recirculation of filtered indoor air D) planning separate rooms for large copiers E) specifying materials with low VOCs F) prohibiting smoking on all floors of the building. B, D, E, F Developing a maintenance manual, using separate rooms for large copiers, specifying materials with low volatile organic compounds (VOCs), and prohibiting smoking on all floors are the best ways to establish and maintain good indoor air quality. Although post-occupancy evaluation is a good tool for verifying that earlier decisions indoor air quality are being maintained, it does little for actually maximizing indoor air quality. Instead of maximizing recirculation of indoor air, outdoor air should be brought into the building. An interior designer has been retained to redesign a call center in a large warehouse. The call center will have a high-density employee occupancy. As part of due diligence, what must the interior designer do to determine whether the existing sanitary fixtures will be sufficient? A) Count the number of existing sanitary fixtures and compare to the requirements of the AHJ. B) Ask the client how many fixtures were previously used and document this number in the due diligence report. C) Find the required number of fixtures in the International Plumbing Code and use this full number in the new design. D) Ask the local building official for a recommendation. A. The International Plumbing Code, as amended by the local authority having jurisdiction (AHJ), will give the minimum required number of sanitary fixtures (e.g., toilets, urinals, lavatories, and drinking fountains) based on the occupancy type and occupant load (i.e., the number of people to use the fixtures). The interior designer can count the number of existing fixtures, make the comparison, and tell the client what the planning and cost implications are. If questions remain or if it is still unclear how many fixtures are required, the interior designer can then ask the local building official, though doing so is not always necessary nor part of due diligence. Also, the building official would only know the total number of fixtures required, not the existing number of fixtures. it would still be necessary for the designer to count the existing fixtures to determining whether the number sufficiently meets code and AHJ requirements. Including the full number of code-required fixtures in the design is unnecessary and costlier than just including the difference between what is needed and what already exists. The client is not qualified to determine the minimum number required by code or regulations. The MOST economical way to create a column-free space in a new home addition is to use A) plywood web I-joists B) double joists C) laminated veneer lumber D) glued laminated lumber A. Plywood web I-joists are specifically designed to replace joists to allow for longer spans economically because they use relatively thin plywood for the webs and small solid wood pieces for the flanges in an efficient configuration. Double joists would not be economical or practical to increase span distances because twice as much lumber would be required, and locating long joists is difficult. Laminated veneer lumber is commonly used as a replacement for headers, studs, and shorter beams, not as a replacement for joists. Glued laminated lumber would not be appropriate because it is used for long-span beams that support other structural members. Typically, the MOST effective action in interior designer can take to maximize daylighting is to A) change the type of glazing B) increase the head heights of glazing C) install a light shelf D) specify a high-reflectance paint D. The interior designer can typically influence only the surface finishes and reflectance of rooms; therefore, to maximize the daylighting, the interior designer should specify a high-reflectance paint. Light shelves and glazing are usually part of the building's architecture and are outside the interior designer's control. An interior designer is planning a laboratory space adjacent to a restroom. What type of partition construction would best accommodate the plumbing and other services necessary to serve both spaces? A) metal studs 6" deep with gypsum board on both sides B) double masonry with space between C) demountable partition D) a chase wall D. A chase wall consists of two runs of studs separated by a distance to allow for installation of all services. To accommodate the plumbing pipes, gas piping, electrical conductors, and other services typically required for a laboratory and restroom, a chase wall is the appropriate choice. Metal studs 6" deep would not provide a sufficient space for the services and would make horizontal runs of piping difficult. A demountable partition is only appropriate for spaces that need to be reconfigured frequently, and it would not provide a space for services. In the partial section of a glass block partition, drag the material labels from the left into the boxes on the section detail. support frame anchor asphalt emulsion packing glass unit masonry expansion strip mortar joint sealant The section shows a typical interior glass block (glass unit masonry) partition. The first course of block is laid with mortar over an asphalt emulsion. Subsequent courses are laid with mortar, and the horizontal joint reinforcement is provided at every other horizontal joint, at a minimum of 16" on center. At the top course below the structure (either concrete or steel framing), an expansion strip is used to accommodate structural deflection as well as any expansion that may occur in the wall itself. An anchor is used to attach the support frame to the structure. Packing is place between the block and the frame and finished with joint sealant. Of the open-plan workstations shown, which is MOST efficient and well suited for frequent visitor conferences? D. Layout D is the only one that is both efficient and appropriate for frequent visitor conferences. Layout A and B are appropriate for frequent conferences, but neither uses space as efficiently as layout D. Layout C is efficient but not well suited for frequent visitor conferences because it would be difficult for the worker to get to his or her desk when a visitor was present and because the arrangement of the chairs would make talking awkward. Changing a ceiling from gypsum wallboard to accoustic tile would Most affect the room's A) reverberation time B) sound transmission C) decibel loss D) impact insulation class A. Changing from wallboard to acoustic tile affects the total absorption of a room and thereby changes the reverberation time. Prior to determining the preferred location of luminaires, the interior designer is reviewing the mechanical engineer's HVAC layout, as shown in the partial plan in the illustration. If there is a conflict in position between a luminaire and ductwork, which ductwork would be the easiest and least expensive to relocate? A) duct A B) duct B C) duct C D) duct D B. Duct B is a flexible duct and could be pushed out of the way or relocated easily along with the supply air diffuser to which it is attached. Duct A is a small duct for the exhaust fans in the janitor closet and restrooms. Duct C is an 8" x 10" rigid duct and would be only moderately easy to relocate. Duct D is a larger rigid duct and would be difficult to move. In a small lecture hall, it would be BEST to avoid A) a sound amplification system B) a vaulted ceiling C) carpet D) parallel walls B. A vaulted ceiling would focus sound reflections into one concentrated area and produce annoying echoes or quiet spots in the hall. What is the unit to measure luminance? A) footcandles B) footlamberts C) candelas D) lumens B Luminance is the brightness reflected or transmitted from a projected area (i.e., only the area that you see when looking at the source). In other words, it is the brightness of a direct glare source. In the older inch-pound system, luminace is measured in footlamberts (ftL), where one footlambert is equal to the reciprocal of π in candelas per square foot (written 1 ftL = 1/π cd/ft² When working on a home remodeling project, which type of electrical conductor is the interior designer MOST likely to encounter? A) armored cable (AC) B) electrical metallic tube conduit (EMT) C) intermediate metal conduit (IMC) D) nonmetallic sheathed cable (NM) D. For residential construction, NM, or Romex®, is typically used. This consists of two or more plastic-insulated conductors and ground wire surrounded by a moisture-resistant plastic covering. It is relatively inexpensive and easy to install through wood-frame construction. The other types of conductors are used in commercial construction. One of the MOST frequent problems in traditional drafting rooms is A) veiling reflection B) direct glare C) visual comfort D) excessive brightness ratio A. Any lights in the ceiling of a drafting room are reflected off plastic triangles, parallel bars, and computer screens, causing veiling reflections. The interior designer is responsible for which of the following life safety considerations? (Choose the four that apply.) A) maintaining compartmentation according to the original architect's plans B) planning for an exhaust system in the remodeled spaces C) locating fire extinguishers as required by the local fire code D) specifying gaskets and closers on fire doors E) including fire protection of structural members according to the building type F) locating fire dampers in new ductwork where fire partitions have been located A, C, D, E The interior designer is responsible for maintaining compartmentation, locating fire extinguishers, specifying gaskets and closers on fire doors, and including fire protection of structural members. The mechanical engineer is responsible for any exhaust system, if one is required. The mechanical engineer is also responsible for locating and specifying fire dampers, but the placement of these items is based on the location of any fire separations determined by the interior designer. What types of lamps would be best to use in the display cases inside a jewelry store? (Choose the three that apply.) A) 75W Par quartz B) 150W R quartz C) 14W T5 flourescent D) 90W MR-16 E) 40W T10 F) 20W LED C, D, F There are two aspects to consider for this application: size and color rendition. T5 fluorescent lamps can be specified with a high color temperature and are small enough to fit within most types of display cases. MR-16 lamps are relatively small and are tungsten-halogen lamps that would provide good color rendition and sparkle to jewelry. Light-emiting diode (LED) lamps would be the best choice because of their small size, cool operating temperatures, and availability in a variety of color outputs. Both the 75W parabolic aluminized reflector (PAR) and 150W reflector (R) lamps would be too large to use in a display case and would generate a great deal of heat. A 40W T10 would be small enough to use in the display case, but its incandescant color redition would be too warm for jewelry display. To obtain a building permit after the contract documents are completed, the interior designer should A) give the documents to the client, who will transmit them to the authority having jurisdiction (AHJ) B) forward the required number of drawing sets to the contractor, who will submit them to the AHJ C) submit the documents directly to the AHJ and provide a copy to the contractor D) provide the documents when requested by the AHJ after submitting a permit application fee B The contractor is typically responsible for submitting the construction documents, along with an application and fee, to the building department or AHJ. An interior designer has just finished reviewing the plans for a large office suite when the building department states that the lighting budget has been exceeded. If the design is composed of 80% fluorescent lighting and 20% incandescent lighting, what is the BEST course of action to begin redesign? A) Reduce the number of luminaires by spacing them farther apart. B) Substitute all incandescent lights with fluorescent lights. C) Change to a task-ambient lighting system. D) Investigate whether lamps with higher efficacies will bring the design within the budget. D Option D allows everything but the lamps to be left unchanged. If this investigation did not bring the design within the budget, then the other options consistent with the design could be explored. Option A is not the best action because the illumination can easily be lowered below an acceptable level. Option B is a possibility and may ultimately be necessary, but other options should be explored first because the question asks what should be done to begin redesign. Option C is also a possibility, but the original design was developed for a reason and the first action should be to try to make that work. What type of cushioning would be BEST for a hospital waiting room? A) high-density foam B) cotton batting C) combustion-modified foam with a low ILD D) low-density polyurethane A. High-density foam is used to create firm cushions. Firmer cushions prevent fabric coverings from stretching, thereby extending their useful life and appearance from the constant and heavy use of a hospital's waiting room. Cotton batting and low-density polyurethane are not as durable as high-density foam, and any material with a low indentation load deflection (ILD) implies a soft cushion (which is also much less durable than a firm cushion). A client for a small retail store has a budget of $1,114,000 for the design of a new store in a strip mall. A project completed in 2015 of similar size and construction type had a total cost of $980,000. The present-year construction cost index in the same city is 143. Refer to the table shown. The current project is underfunded by $____________. $160,000.00 The first step is to calculate the ratio between the cost indices by dividing the present-year index by the historical cost index from the year that the previous project was completed. 143/110 = 1.3 Then multiply the cost index ratio by the cost of the previous similar project to get the estimate for the current construction cost. $980,000 x 1.3 = $1,274,000 Finally, subtract the budget for the new project from the estimated current construction cost to determine the amount of underfunding. $1,274,000 - $1,114,000 = $160,000 In preparing a budget, which of the following elements would an interior designer MOST likely ask the client to include? A) legal fees and artwork consulting B) taxes on furniture and computer system installation C) contingencies and an interior designer's fee D) furnishings and furniture delivery A. Legal fees and specialty consulting (like artwork advice) are often separated from the construction and furnishings budget that the interior designer prepares. The items in the other three options can be estimated by the interior designer (unlike legal fees) and are often place in the designer's budget work.
