Prac 1.2 Flashcards
What is the minimum allowable size for a room?
The minimum allowable square footage is 70 square feet.
When identifying partitions where acoustical separation is MOST important, you need to think in terms of quiet and loud spaces and what should not be close together - noise-wise.
Controlling sound transmission between interior spaces can be achieved by:
-Separation of noisy and quiet areas by space planning, including the use of intervening spaces to buffer sound.
-Slab-to-slab partitions without penetrations and sealing /staggering any necessary penetrations.
-Using double-layer wallboard and/or resilient channels.
-Insulating partitions with fiberglass or other acoustic batting material.
The EPAct specifies flow rates for water closets to be no more than _______ gallons per flush (gpf) or _______ liters per flush (lpf).
1.6.
You will also find many newer toilets that function perfectly with only 1.28 gpf.
Seat height for accessible toilets is between _______ inches.
17 and 19.
What are areas in residences that smoke detectors must meet specific restrictions?
Smoke alarms should not be installed within a specific distance from cooking appliances (depending upon the type of SD).
Smoke detectors must also be at least 3 feet away from the door to bathrooms with a tub or shower.
True or false:
USB outlets may be combined with single or duplex outlets of normal voltage/amperage.
True.
USB outlets do NOT require AFCI unless paired with an outlet of normal voltage/amperage.
Outlets with USB outlets only would not require AFCI protection.
Flatscreen TVs require what types of power options?
Duplex and data for the flatscreen TV, both at higher AFF - if need be.
_______ fire signal devices must be visible from any location in the room or space, so in some cases, two may be required. These must be visible to occupants from either side of the corridor.
A/V.
Are A/V and visible alarms required in the same locations?
No.
A/V fire signal devices must be visible from any location in the room or space, so in some cases, two may be required. These must be visible to occupants from either side of the corridor.
*Per 907.5.2.3.1 Public use areas and common use areas, visible alarms are required for common use areas such as the reception area and conference room. Note that these are not the combination audible/visible alarm devices; they are silent white or clear strobe lights mounted on the wall in certain areas — visual/visible alarms only.
Occupancy classification affects the following:
-Calculations for occupant load
-Egress design
-Interior finish requirements
-Use of fire partitions and fire barriers
-Fire detection/suppression systems
-Ventilation/sanitation requirements
-Other special restrictions particular to any given classification
When a building is equipped with an automatic sprinkler system, the required hourly ratings of a partition are generally reduced by _______.
1 hour.
Construction type can affect:
Required fire ratings if coverings of structural elements, floor/ceiling assemblies, and openings in rated walls.
Three types of adjacency  needs:
People, products, and information.
What takes into account the required circulation space needed per tenant, as well as the non-useable area required for partitions, columns, and so on.
Efficiency Factor.
Occupant area is?
The total portion of the building being actively used by a tenant.
Efficiency factors generally range from?
.60 to .80 with most offices and retail spaces having an efficiency factor of .70-.80.
This means that approximately 20-30% of the net area (estimated required occupant area) is devoted to non-useable areas.
The actual area each tenant uses is?
Occupant area.
In addition to a prorated share of portions of the building used by all tenants.
This and the load factor account for the rentable area.
What’s something that you should think of when you see that a building is fully sprinklered?
The travel distance between exits: 1/3 if fully sprinklered for spaces.
How do you calculate load factor?
Sqft divided by the load factor. IBC 1004.5. Ie. 15 net, 150 gross etc.
Sets the tone for all of the egress.
When getting the total occupant loads, what is the proper way to calculate this?
By calculating each individual space and then adding the totals.
Ie. sqft / by occupant load factor (table 1004.5) for ALL spaces, then add.
For fixed seating without dividing arms, the occupant load is based on one person for each _______ of seating length.
18”.
For seating booths, assumed unit is one person for each _______ of booth seat length.
24”.
What are gross and net when it comes to occupant load factors?
Gross is the floor area including stairs, corridors, toilet rooms, mechanical rooms, closets and interior partition thickness.
Net is the floor area of the space actually used.
True or false:
The number of exits per story is the same calculations/qtys as the number of exits per space.
False.
These are located in two different locations of the IBC: 1006.2.1 for space and 1006.3.2 per floor.
What are the occupants per story to require these minimum number of exits:
2, 3, and 4.
1-500 occupants = 2 exits
501-1,000 occupants = 3 exits
More than 1,000 = 4 exits
Tactile characters on signs shall be located a minimum of how many inches above the finish floor.
Tactile characters should be 48” min AFF and maximum 60” AFF.
For electrical, in a complex plan of decent size and scale or for larger plans such as for complex commercial projects, the interior designer often draws a separate _______.
Power/communications plan.
This is different from the electrical engineer’s power plan.
For a smaller scale project, the outlets are often shown on the furniture plan. The location of outlets would not be shown on the RCP, and the construction plan would become too cluttered with the required information.
On which drawings would you find the abbreviations NIC, BRK, FPL?
On the floor plans, also called working drawings, you may see abbreviations like:
NIC: not in contract
BRK: break
FPL: fireplace
As abbreviations may vary, these should also be listed in the drawing legend.
What’s another name for working drawings?
Floor plans or partition plans.
Construction plans, also called floor plans or partition plans, are the most common type of floor plan and are required for every project regardless of size or complexity.
True or false:
Demolition is shown on a Partition Plan.
False.
Demolition is not shown on a Partition Plan. Generally anything denoted as a dashed line on a Partition Plan means it is an element happening above.
_______ is ready-made, profiled, or finished carpentry produced in a mill.
_______ refers to the making of fine furniture or other woodwork.
_______ is a term used for commercial-grade cabinetry.
Millwork.
Cabinetry.
Casework.
What does “VIF” stand for?
Often designers mark “VIF” or “verify in field” on their drawings. This GC, subcontractor, and vendor must then confirm the appropriate size.
What type of substrate is used for supporting heavier stone or solid surfaces countertops, but not for lamination.
Plywood.
What types of substrate is used for laminate finishes?
MDF and particleboard.
Particleboard
Dimensionally stable and provides a smooth surface for laminating. Provides impact resistance and strength for gripping screws for constructing panels and casework.
MDF
It is dimensionally stable, so it does not warp, crack, or cup. It has a dense composition that allows for routing but does not hold screws as well as particleboard. It is smoother than particleboard, so more suitable for gloss laminates and finishes. Special fire-resistant MDF is available.
Commercial-grade cabinets are most often constructed of panel products with a thickness of?
The majority of a cabinet is built with 3⁄4 in panels including the bottom, sides, and top bracing. The back is typically 1⁄4 in.
For the most durable wood finish for a reception desk, which of the following finish types should be specified?
-polyester
-lacquer
-varnish
-polyurethane
Polyurethane and polyester are both very durable, synthetic finishes, yet polyester only comes in high gloss, which would not be as appropriate for a high-touch application.
For hospitality use, a standard spec is “minimum 3 coats clear catalyzed polyurethane”.
A designer could use all of the following to add visual interest to the ceiling of a space except?
-beams
-coffers
-grass cloth or wallpaper
-pilasters
A pilaster serves both structural and decorative roles in interior architecture. Structurally, it can support or reinforce walls, while aesthetically, it mimics the appearance of a column, adding visual interest and framing to a building’s design. Pilasters also help to guide the viewer’s gaze upward, enhancing the verticality of a space, but not included on the ceiling.
When rooms or walls have complex finishes, it may be necessary to supplement the finish schedule with _______.
Wall elevations.
Schedules are the most effective way to communicate large amounts of complex information in a small space - just a note.
Some code-required drawings must be provided as part of any set of documents prepared and submitted for a building permit.
While this varies by project, these usually include:
-Egress
-Emergency signage
-Fire detection and alarm systems
-Sprinkler systems
-Accessibility
-Plumbing fixture counts
Another name for a life safety plan is a?
Evacuation plan.
Smoke detectors are typically required in _______ for commercial projects. They are required in all _______ for residential projects.
Every room.
Sleeping areas/outside sleeping areas.
In general, _______ are best located near windows or other heat loss sources or heat gain. _______ should be placed away from the supply points.
Air supply diffusers and registers; Return air grilles.
This facilitates heat and air circulation throughout the space.
A device used to supply or extract air without any deflection is called a?
Grille.
_______ lighting provides overall illumination.
And what is another name for it?
Ambient lighting.
Also called general lighting, is a more general and uniform way to light the space. The goal of ambient lighting is to provide enough footcandles across the entire area with little variety.
The color rendering index (CRI) is a rating that measures the lamp’s color rendering accuracy. Each lamp type has a different CRI based on a scale of _______.
In most spaces, a CRI of _______ or higher is acceptable.
0-100; 80.
The higher CRI renders color more naturally.
_______ have poor efficacy.
Incandescents.
This means they require a relatively higher wattage for the lumens output. They have a high CRI for rendering natural color and skin tones appropriate for residential uses.
All of the following are true about a low voltage lamp EXCEPT?
-Are another class of incandescent lamps.
-Is a semiconductor device that uses solid-state electronics to create light.
-Typically operate at 12V.
-Provide better beam control than a standard incandescent lamp.
Is a semiconductor device that uses solid-state electronics to create light.
Not all low voltage lamps are LEDs. Some incandescent and halogen lamps are designed to operate at a reduced voltage and are also called low voltage lamps.
These lamps operate at a lower voltage than 120V, usually 12V. Because the filaments are thicker, they are also more compact, resulting in smaller lamps and better beam control lamps.
A transformer is required to step down the line voltage. This results in a bulkier luminaire and higher initial cost.
One type of low voltage lamp, a light-emitting diode (LED), is a semiconductor device that uses solid-state lighting that includes organic light-emitting diodes and light-emitting polymers.
It is important to ALWAYS round up for calculations with _______ and ________.
Egress and occupant load. And sqft.
You want to give the longer distance as it’s safer and you can’t have a partial person. Things related to life safety (HSW) or BOMA sqft.
HSW - Health, Safety, and Welfare.
Booths and benches have special circumstances- don’t round up.
What takes into account the required circulation space needed per tenant, as well as the non-useable area required for partitions, columns, and so on?
Efficiency Factor.
What type of facility would have a lower efficiency factor?
A hospital with many small rooms and large corridors.
Building where less space is allotted for corridors and other non-useable areas will have a better efficiency factor.
Even if the occupant load of a building space is less than what is shown in table 1006.2.1 (Spaces with one exit or exit access doorway), _______ exits are still required if the common path of egress travel exceeds the limits given in the same table.
2 exits.
Are exit access areas of a building protected?
Once a person is safely in an exit, travel distance is not an issue. Because exit access areas are NOT protected, the codes limit how far someone must travel to safety.
Maximum travel distances are based on?
The occupancy of the building and whether or not the building is sprinklered.
Max travel distances in IBC table 1017.2.
If three or more exits are required in a space, how must these be spaced?
2 exits must be placed the required 1/2 or 1/3 distance apart of the maximum overall diagonal dimension of the building or area being served.
The third or fourth exits must be arranged at a reasonable distance apart so that if one becomes blocked the others will be available.
Typical common path of travel max distance for A, E, M, and B occupancies?
75’ with and without sprinklers.
Typical Exit Access travel distance for A, E, M occupancies - with and without sprinklers?
B occupancy?
Without sprinklers 200 ft, with 250 ft.
For business 200 ft, with 300 ft.
The required minimum widths of exits is determined by multiplying the occupant load factor of _______ for stairways and _______ for corridors and other egress components.
.3 in for stairways and .2 in for corridors - multiply against the occupant load of a space or the total occupant loads in a building/floor.
If more than one stairway, divide the total occupant load.
Remember NOT to have egress widths less than in the IBC.
The required stairway widths for stairways serving more than one story are calculated how?
By using the occupant of each story SEPARATELY, rather than the combined occupant load.
