category I Flashcards
Your site is located between the Pacific Coast Highway and the ocean. Which two agency approvals will you need that are specific to this site?
// the county planning department/planning commission (coastal act)
You are asked to design a project in a flood plain next to a navigable river. From which agencies will you need approval to build due to these factors?
// u.s. army corps of engineers (navigable waterways)
// state water resources control board (if more than one acre will be disturbed during construction)
// the county flood control district (floor plain)
// department of fish and game (if the project will alter the river bed)
You are asked to design a boathouse on a lake. Endanged plant species grow on the site; there is no water and sewage service available. The site is located in a fire hazard severity zone. Which agency approvals will be required due to these specific factors?
// the county department of environmental health (wells and septic system)
// the county fire marshall (additional review required due to fire hazard severity zone)
// the department of fish and game (endangered plant species)
// the department of fish and game (lake bed affected by dock)
Your client wants to build a large three story hotel on a wetlands area. Which agency approvals are required due to these factors?
// the regional water quality board (wetlands)
// u.s. army corps of engineers (wetlands)
// state water resources control board (more than one acre will be disturbed during construction)
A client comes to you wanting to design and construct an office building. The site is adjacent to an airport. What agency approvals/regulations must be satisfied due to the site location?
// federal aviation adminsitration regulations (height and outdoor lighting)
// airport authority land use plan (height, programming, construction standards)
How can the hazards associated with flooding be mitigated?
flood waters from accumulating
// the second step is to raise the elevation of the structure above anticipated floor levels
// in order to qualify for the national floor insurance program, the building must be elevated above the 100 year floor level
What are the basic fire engineering principles that can be applied to reduce the risk of wildfires?
// removing or reducing the heat source
// modifying or reducing fuels
// preventing the heat source from coming into contact with ignitable fuels
How can the risk of damage from seismic activity be reduced?
// earthquakes cause damage by two basic means: seismic shaking and ground failure
// seismic shaking causes the vast majority of damage, but ground failure (e.g. fault rupture, liquefaction, landslides), although less common, is catastrophic to the immediate area affected
// seismic shaking: brace and tie down heavy building elements and equipment, brace or stiffen structural systems, provide extra structural support for emergency systems such as fire sprinklers
// ground failure: modify unstable ground to increase stability through grading, compacting, or reinforcing soils
How can an architect minimize the risk of hazardous materials affecting building occupants?
// do not specify materials that contains hazardous materials (e.g. high VOCs)
// if the site has a history of industrial activity of hazardous materials handling (e.g. gas stations), recommend the owner perform a hazardous materials survey and proceed with abatement procedures prior to construction
// if the site is in a suspected methane zone, recommend that the owner conduct a methane survey. if methane is present then include a methane barrier in the foundation and floor design
How can wind hazards be reduced?
// damage from winds fall into two basic categories:
// damage from the wind itself: the risk of wind damage can be mitigated to orient the building to expose less surface area to prevailing winds and reducing building height. also, wind damage can be minimized by reducing building overhangs such as eaves or open roofs and using ties to strengthen roof connections
// damage from wind borne debris: vulnerable portions of the building, such as windows, skylights, and curtain walls, should be design to resist missile impact forces
What are three structural systems that can be used to resist lateral loading?
// shear walls
// steel moment frames
// braced steel frames
What are volatile organic compounds (VOCs)?
// volatile organic compounds (VOCs) are carbon based chmicals emitted as gases from certain solids or liquids at room temperature
// in sufficient quantities, VOCs can cause eye, nose, and throat irritations, headaches, dizziness, visual disorders, memory impairment; some are known to cause cancer in animals; some are suspected of causing, or are known to cause, cancer in humans
Name four common sources for VOC off-gassing in finished construction.
// carpets
// adhesives
// paints and coatings
// composite wood products (hardwood plywood, particle board, and MDF)
// resilient flooring systems
// thermal insulation
// acoustic ceilings and wall panels
What are the two methods of controlling indoor pollutants such as VOCs and carbon dioxide?
// control of pollutants at the sources is the most effective strategy for maintaining quality indoor air. specifying materials with low VOC emissions is one method of control
// ventilation, either natural or mechanical, is the second most effective approach to providing clean indoor air
What are the possible health effects of mold on building occupants?
// exposure to molds can cause symptions such as nasal stuffiness, eye irritation, wheezing, or skin irritation
// some people, such as those with serious allergies to molds, may have more severe reactions
// severe reactions may include fever and shortness of breath
// some people with chronic lung illnesses, such as obstructive lung disease, may develop mold infections in their lungs
What are ways to control mold in buildings?
// mold is caused by excessive indoor moisture or water accumulation, particulary if the moisture problem remains undiscovered or unaddressed
// the way to control indoor mold growth is to control moisture with proper water and damp-proofing during design and construction as well as by minimizing water absorbent materials through natural or mechanical ventilation
