Q

Down feed distribution is: a. A water supply system that uses a pressurized tank, usually in the basement, to supply water under pressure to the floors above. b. A water supply system used in tall buildings in which water from the street main is pumped to a rooftop storage tank and distributed to the building under pressure from gravity. Pressure is determined largely by the height difference between the tank and the floor served. Significant weight on the roof may require additional structure. c. A water mechanical system used only for heating. Many of these systems are also radiant systems. Some systems circulate hot water or steam to warm the building

Q

Which of the following would have the greatest impact on the size and configuration of an accessible restroom? A. a 5 ft clear circular turnaround space B. maneuvering space on the outside of the entry door to the room C. clear space at towel dispensers and full-height mirrors D. a minimum 36 in access route into and through the room

A

A. a 5 ft clear circular turnaround space Providing for a 5 ft turning circle requires the most space of the four choices listed. If the turning circle is provided, it is very likely that a 36 in access space and clear space at the towel dispensers will also be available. The maneuvering space on the outside of the entry door is irrelevant to the interior dimension of the restroom.

Q

Types of Escalator Configurations:

A
  • Parallel: up and down escalators “side by side or separated by a distance”, seen often in metro stations and multilevel motion picture theaters
  • Crisscross: minimizes structural space requirements by “stacking” escalators that go in one direction, frequently used in department stores or shopping centers
  • Multiple Parallel: two or more escalators together that travel in one direction next to one or two escalators in the same bank that travel in the other direction
  • A designer seeking to avoid the resentment and confusion of building occupants would design a separation between escalators in a crisscross walk-around of no more than 10 ft
  • It is not advisable to use the stacked parallel arrangement of escalators beyond 2 floors, as users will become annoyed at the long walk-around.
  • Moving Sidewalk
57
Q

Communication Systems:

A

include intercoms, paging devices, sound systems, TV,
CCTV, LAN and (most prevalent) telephone.

58
Q

LAN:

A

a data communication system allowing a number of independent devices to communicate directly with each other and within a moderate sized area

  • Designed in the 1980s to link personal computers together enabling them to communicate
  • Includes computers, network interface card, communication cable, hubs/switches
  • Each station has to have a direct cable connection to a port on the hub
59
Q

• Building Automation and Control Systems (BACS)

A
  • Regulate a building’s environment or monitor it for safety or security • Use a centralized control unit and distributed sensors or devices
  • Each sensor connects to a port on the centralized control
  • Systems include:
60
Q

Hydraulic Elevator:

A

an elevator lifted by a plunger or ram

• Used for low-rise, or less than 5 story buildings, or about 50’-0”
• Speed varies between 25 - 150 feet per minute
• Can carry about 10 tons
• Commonly used for freight in industrial and low-rise commercial buildings,
passengers in small buildings, or single family residential
• Sit over a plunger or ram which operates a cylinder that extends as far into the
ground as it is tall.
• Oil serves as the pressure fluid and is controlled by high speed pumps
• The main advantage of hydraulic elevator systems is that they don’t require a
penthouse machine room or heavily braced roof over the shaft
• Cost less than electric elevators because they are more simple
• Holeless Hydraulic: uses a telescoping plunger set into the shaft next to the
cab. Lift is provided by applying force to the upper member of the car frame

61
Q

Electric (Traction) Elevator:

A

an elevator lifted by cables

• Used in commercial and industrial buildings greater than 5 stories/50’-0”
• Speeds up to 1,800 feet per minute
• Capacities up to 10,000 pounds
• Traction is used to transmit lifting power to the hoisting cables by means of
friction that develops when cables run over grooves in the sheave
• On one end is the elevator cab and the other are counterweights that weigh
about the weight of an empty car plus 40% of the live load capacity
• Traction machine: Motor and drum assembly that is geared or gearless
• Gearless: motor, sheave, and break all mounded on a common shaft, so 1
revolution of the motor means one turn of the main sheave (typically used for
passenger service)
• Geared: motor and break on one shaft which drives a second main shaft, used
for high speed installation
• Roping: the arrangement of cables supporting the elevator
• Single wrap: simplest, cables pass only once over elevator machine sheave and
then connected to the counterweight

  • Double wrap: cables pass over the sheave twice, get worn out faster, used for high speed elevators where more traction is required
  • 1:1 Roping: when the rope is directly connected to the counterweight, the cable travels in the opposite direction as far as the car
  • 1:2 Roping: when the rope is wrapped around a sheave on the counterweight and connected to the top of the shaft the rope moves twice as fast as the car, but requires less weigh to be lifted. (Car travels twice as far as the piston)

Q

Building Owners and Managers Association (BOMA):

A

professional organization that
for commercial real estate professionals

63
Q

Fair Housing Act:

Q

HUD:

A

65
Q

American Society for Testing and Materials (ASTM)

A

• establishes standard specifications for commonly used materials of construction.
• Generally referred to by number (eg: C150 = specification for portland cement)
• numbers are frequently used in specifications for specific/precise shorthand
designation for the quality of material that is required.

66
Q

American National Standards Institute (ANSI)

A

• develops standards for many industrial products (eg: aluminum windows, mechanical components of buildings)

67
Q

MasterFormat/Construction Specifications Institute (CSI)

A
  • a standard for organizing information about constriction materials and components. • MasterFormat is used as the outline for project specifications
  • In 2004 the system was updated from 16 divisions to 50 divisions
