Q

6 goals of sustainability

A
  1. reduce building energy usage and utilize sunlight and wind as energy sources for our buildings (REDUCE DEPLETION OF FOSSIL FUELS)
  2. reuse existing buildings and arrange new building in compact patterns on land (MINIMIZE THE WASTE OF PRODUCTIVE LAND)
  3. harvest wood from managed forests (MAINTAIN WOOD CONSTRUCTION AND PROTECT THE ECOSYSTEM)
  4. protect soil and water (RETAIN THESE RESOURCES FOR OUR SUCCESSORS)
  5. reduce pollution (WE KEEP THE ENVIRONMENT CLEANER)
  6. commit to designing and building sustainably

16
Q

standards

A

developed by organizations through voluntary consensus with the involvement of subject matter experts. they are not enforceable

17
Q

codes

A

are standards that have been enacted into law by the government or authority.

18
Q

model codes

A

developed by an organization to have as an industry-wide standard. they are not enforceable

19
Q

other codes

A
  • energy codes established standards of energy efficiency for buildings
  • electrical and mechanical codes regulate the design and installation of building electrical, plumbing, and heating and cooling
  • codes that regulate the operation and maintenance of buildings to ensure that egress pathways, emergency power, and other life-safety systems
20
Q

Design stage - constraints

A
  • the Canadians with disabilities act (CDA) access standards
  • the Canadian center for occupational health and safety (CCOHS) controls the design of workplaces to minimize hazards to the health and safety of workers
  • indoor air quality; limitations on the amount of volatile organic compounds (VOCs)
21
Q

standards-setting agencies (building products and systems)

A
  • ASTM internationl, or the canadian standards association (CSA)
  • The American national standard institute (ANSI)
  • government agencies - (NRC-IRC) (NIST)
22
Q

MasterFormat

A

organize information about construction materials and systems
has 50 primary divisions subdivided into sections

23
Q

design/bid/build construction

A

-owner - A/E - subconsultants - design team
owner - Gc - subcontractors - construction team
-PD, SD,DD,CD
-firms invited to bid on the project
-owner evaluates proposals and wards the construction contract
-pros: easy organizational structure

24
Q

design/build construction

A
  • owner - A/E - subconsultants - GC - subcontractors = design/build entity
  • one entity responsible for both design and construction
  • pro: single source of accountability
25
Q

paying construction services

A
  • fixed fee or lump sum compensation (the builder assumes the risk related to unanticipated construction costs)
  • cost plus a fee compensation (the owner assumes the risk related to unanticipated construction costs)
26
Q

sequential vs fast track construction

A

sequential - analyze the structure in detail before starting

fast track - start construction before design is complete. purpose of shortening the time of completion

27
Q

building performance - recurring concerns

A 
fire
building movement of every kind 
the flow of heat and air through building assemblies 
water vapor migration and condensation
water leakage 
acoustical performance 
aging and deterioration of materials 
cleanliness 
building maintenance
28
Q

building construction - recurring concerns

A

division of work between the shop and the building site
optimum use of the various building trades
sequencing of construction operation for maximum productivity
convenient and safe worker access to site
inclement weather
fit building components together
materials and components grading, testing, and inspection
