What would be considered the decibel level of a normal conversation between two people?
60-65 dB
40-45 dB
80-90 dB
100-110 dBA change of 1 decibel is the smallest difference that a human ear can detect (dogs have much better hearing). A typical conversation between two people would range from 60-65 dB.
Which of the following describes a wet pipe fire protection system?
1- Equipped with water to supply upon activation of the fire system in the main pipe as well as the branches
2-Pipes are kept constantly wet in order to increase humidity levels within building spaces and reduce the threat of fire
3- Fire system is activated when a gas is released whereby water then flows through the pipes to eliminate fires
4-Pipes are connected directly to the hydrant system on the site and can be manually activated at the hydrant
Most commonly used sprinkler systems are wet pipe systems, which are equip with water to supply upon activation, both in the main pipe as well as the branches. Due to the risk of leakage, one must take precautions when selecting this simple system for certain spaces.
Which of Kevin Lynch's five features of a common city describes centers of activity?
Nodes
Paths
Districts
EdgesNodes are the centers of activity. These are often landmarks in which people can gather for a function. The can be the core of a district, such as a civic center or entertainment area, or a junction, such as intersection, plaza or public square.
Historically, there were two main types of brick. What are they called?
- Building brick and facing brick
- Red brick and brown brick
- Adobe brick and mud brick
- Formed brick and pressed brick
Historically, there were two main types of brick – building brick (also called common brick) and facing brick. The former were used in any context, whereas the latter were used as exposed surfaces where an improved or special appearance was desired.
Your client would like to build a used car lot along a busy commercial street but used car lots are not permitted in this area. Your client would need to apply for \_\_\_\_\_\_\_\_\_\_\_\_\_ before submitting plans for plan check by Building and Safety.
a conditional use permit
an ordinance
a variance
a non-conditional useYour client would need to apply for a conditional use permit which allows to build or use a building for a purpose not granted in the local zoning code.
An ordinance is a municipal law in addition to a standard building code.
A variance is a request to deviate from some of the requirements of the local zoning code.
A non-conditional use is a term that is not used.
What is the required width for exit stairs in a building with an occupant load of 300?
90"
100"
60"
150"Feedback:
Stair width = (occupant load * 0.3) inches = 300 * 0.3 = 90” ( note that it does not say the building is sprinkled otherwise it will be .2
See Section 2.3.
In terms of sustainability, the process of manufacturing brick and block:
- creates little waste
- uses more embodied energy than aluminum
- creates a lot of waste
- uses more embodied energy than synthetic rubber
In terms of sustainability, the process of manufacturing brick and block creates little waste, and what waste is created is pre-consumer recycled.
The rate at which energy is used or the rate at which work is done is called:
Power
Surge
Electricity
KilowattPower is the rate at which energy is used or the rate at which work is done. The unit to describe it is the Watt (W).
See Section 3.1.
Which electric elevator type is used for high speed applications?
Gearless elevators
Geared elevators
Hydraulic elevators
Freight elevatorsGearless elevators
What type of fire alarm will detect the presence of smoke?
A photoelectric detector
An ionization detector
A rise-in-temperature detector
A combustion detectorA photoelectric detector
What is the maximum height of a wood framed building according to the International Building Code?
65’ with 5-stories
45’ with 3 stories
70’ with 6 stories
There is no maximum height requirement65’ with 5-stories
What is area protection?
-Protection of a room within a building
- Protection of building openings such as doors and windows
-Protection of building objects such as artifacts and furniture
Protection of building occupants
Protection of a room within a building: Area protection offers security to a space by alerting of an intruder’s presence within the building. If perimeter systems fail to activate, sensors placed in rooms can be triggered by a person moving or making noise within the space.
The transfer of heat between two parts of a stationary system caused by a temperature difference between the parts.
- conduction
- radiation
- latency
- convection
Conduction!
One of the three ways that heat can be transferred, conduction is described as the transfer of heat between two parts of a stationary system caused by a temperature difference between the parts.
Unlike flashings, _______ is the only component of a wall that can and should be considered sacrificial.
- face mortar - brick - trim - insulation
By specifying face mortar that is softer and less durable than the masonry it binds, we insure that stresses in the wall cause cracking along mortar joints instead of the more costly brick or stone.
Typically 3 courses of brick with mortar will measure ______ inches height.
- 8 - 6 - 12 - 7
A common brick module is 4” thick and 8” long including a ⅜” vertical mortar joint; the actual dimensions are 3-⅝” thick, 2-¼” high and 7-⅝” wide (three courses equal 8” in height, which happens to be the same as the typical CMU module).
