National Building Code of Canada



From Wikipedia, the free encyclopediaJump to: navigation, search 

The National Building Code of Canada is the model building code of Canada. It is issued by the Institute for Research In Construction (IRC)],[1] a part of the National Research Council of Canada. As a model code, it has no legal status until it is adopted by a jurisdiction that regulates construction.

History

The Constitution of Canada includes the regulation of building construction as a provincial responsibility. In a few cases municipalities have been given the historic right of writing their own building code. In the early years of regulating building construction this caused a patchwork of building codes across Canada.



In 1941 the federal government of Canada published the first National Building Code. This was adopted by the various provinces and municipalities in Canada during the next 20 years.



Since 1960 there has been a revised document about every five years up to 1995. The 2000 edition of the building code was supposed to be an objective or performance-based building. However, this took considerably longer to write than foreseen and the next edition of the National Building Code of Canada was not published until 2005.


 Implementation

The National Building Code is the model building code that forms the basis for all of the provincial building codes except Ontario's.



 Ontario

The 2006 version of Ontario's Building Code[3] has introduced many changes meant to increase the level of harmonization between Ontario, the National Building Code and other Canadian jurisdictions.[4]



Other provinces

Prince Edward Island,[5] Nova Scotia,[6] and Newfoundland and Labrador[7] have legislation enforcing the current version of the National Building Code of Canada, while Manitoba[8] and British Columbia[9] have adopted the 2005 National Building Code as regulations under provincial acts. The building codes of Quebec[10] and Saskatchewan[11] are based on the 1995 National Building Code.



[edit] Alberta

By agreement with the National Research Council of Canada,[12] Alberta is committed to using the National Building Code of Canada as its base document with changes and modifications to suit Alberta needs in regulating the design, construction, alteration, change of use and demolition of buildings.



The Alberta Building Code 2006 was established by the Building Technical Council, a technical council of the Safety Codes Council,[13] after consultation with municipal authorities, provincial government departments, associations, other affected parties and Code users. The Code is published for Alberta by the National Research Council of Canada.



The Alberta Building Code 2006[14] was adopted by provincial regulation on September 2, 2007.[15]



The Alberta Building Code 2006 is developed and administered by Alberta Municipal and Public Affairs.[16] In addition to the production of the Alberta Building Code, Municipal Affairs is responsible for the development and dissemination of code interpretations and alternatives known as STANDATA[17] which come in three forms:



1.Building Code Variances - acceptable alternative solutions to the prescriptive requirements (known as Alternative Solutions) in Division B.



2.Building Code Interpretations - interpretations on Code items



3.Building Code Bulletins - additional explanatory information on Code items or general Code topics

 Vancouver

Under the Vancouver Building Bylaw, Vancouver has developed its own building code based on the National Building Code.



Content

The intent of the Building Code is to detail the minimum provisions acceptable to maintain the safety of buildings, with specific regard to public health, fire protection, accessibility and structural sufficiency. It is not a textbook for building design. The Building Code concerns construction, renovation, and demolition. It also covers change of use projects where the change would result in increased hazard and/or maintenance and operation in the existing building. The Code sets out technical requirements for the aforementioned project types and does not pertain to existing buildings.



The 1995 National Building Code is split into 9 parts.



Part 1 Scope and Definitions

Part 2 General Requirements

Part 3 Fire Protection, Occupant Safety and Accessibility

Part 4 Structural Design

Part 5 Environmental Separation

Part 6 Heating, Ventilating and Air-conditioning

Part 7 Plumbing Services

Part 8 Safety Measures at Construction and Demolition Sites

Part 9 Housing and Small Buildings

Part 1 gives the definitions and describes how the building code is applied. Houses and certain other small buildings (less than 3 storeys high and 600 m2) are considered "Part 9 Buildings" and only parts 1, 2, 4, 5, 6, 7, 8 and 9 apply. Larger buildings are considered "Part 3 buildings" and parts 1 through 8 apply. Part 3 is the largest and most complicated part of the building code. It is intended to be used by engineers and architects. Part 9 is very prescriptive and is intended to be able to be applied by contractors.



The building code also references hundreds of other construction documents that are legally incorporated by reference and thus part of the enforceable code. This includes many design, material testing, installation and commissioning documents that are produced by a number of private organizations. Most prominent among these are the Canadian Electrical Code, Underwriters Laboratories of Canada[18] a subsidiary of Underwriters Laboratories, documents on fire alarm design, and a number of National Fire Protection Association documents.

Casualties "minor injuries", unconfirmed[1]



The 2010 Central Canada earthquake was a magnitude 5.0 earthquake (downgraded from 5.5) which occurred in Central Canada on June 23, 2010 at about 13:41:41 EDT and lasted about 20 seconds.[1][2]



The quake was centered around 50 kilometres (31 mi) north of Ottawa, Ontario,[3] closest to the settlement of Val-des-Bois, Quebec.[4] It was felt across the Greater Toronto Area, Hamilton, ON [5], Regional Municipality of Waterloo[6], Metro Detroit-Windsor, Ontario-Ann Arbor and Milwaukee areas,[7] the Greater Montreal Area, Quebec City, Boston, Delaware, Greater Hartford, Buffalo, Pittsburgh,[8] Cleveland,[9] New Hampshire,[10] New York City[11] and Chicago,[12] in addition to places as far as Moose Factory, Thunder Bay, Evansville, Baltimore, Charleston, West Virginia, and Halifax, Nova Scotia.[13] This earthquake was the most severe earthquake in the Ottawa Valley region since October 1998, when a 5.4 earthquake struck the area.[9][14] However, in terms of the Western Quebec Seismic Zone, it was the first moderate earthquake since April 20, 2002, when the area was affected by magnitude 5.5 tremors.[15][16]



Although a 5.0 magnitude quake is only considered to be moderate, the earthquake's depth (estimates of which vary between 16.4 kilometres (10.2 mi) and 19.0 kilometres (11.8 mi))[17][18][19] meant that its effects were more widely felt.[20]

[edit] Geology



USGS intensity map.The magnitude 5.0 Mw intraplate earthquake occurred near the southern edge of the Western Quebec Seismic Zone, known for frequent, but minor tremors, occurring, on average, every five days.[15][21] Far away from the North American tectonic plate's margin, the regional seismicity is controlled by a series of geologic faults, formed over the last billion years by the processes of mountain building, including the Grenville orogeny, and subsequent erosion.



[edit] Aftermath

The Globe and Mail reported that "Twitter users as distant as Springfield, Massachusetts, Traverse City, Michigan, and Cincinnati, Ohio reported feeling tremors."[1] This earthquake occurred as Canadian environment minister Jim Prentice was conducting an interview in Ottawa, and he reported that his chair started to move.[22] The offices of The Globe and Mail were evacuated soon after the tremor.[1] Several media outlets also aired video of a press conference by New Democratic Party Member of Parliament Don Davies being disrupted by the quake.[23]



Part of Quebec Route 307 was closed due to a partial bridge collapse near Bowman, which injured a nearby fisherman.[24] Near the epicenter, many of the telephone networks were out. The Ottawa-Carleton District School Board evacuated most of its schools, but students were allowed to return when the situation was determined to be safe. A number of schools were damaged, and may be closed, including First Avenue Public School, Churchill Alternative School, Blossom Park Public School, Centennial Public School, Connaught Public School, Elgin Street Public School and Hilson Avenue Public School.[25] In Gracefield, Quebec a state of emergency was declared after several buildings were damaged, including the church, some of the city's administration buildings and a hotel.[26] In the Outaouais, about 1,300 homes lost power.[24] The O-Train in Ottawa was shut down until 5 pm, and the Agence métropolitaine de transport shut down four of five commuter trains in Montreal for a similar period of time in order to be inspected .[25]



Immediately after the quake, cell phone service in Ottawa was down, possibly overloaded by callers.[14] Several windows in Ottawa City Hall shattered, and a chimney in a nearby solicitors' office collapsed.[26] Minor damages were also reported to several city-owned facilities, including two branches of the Ottawa Public Library and two municipal sports arenas, and power was out in part of the downtown Golden Triangle neighbourhood.[27]



Office buildings in Ottawa and Toronto were evacuated, and cracks appeared in the Parliamentary Press Gallery building on Parliament Hill.[28] A session of the Canadian Senate was also interrupted.[29] No serious damages or injuries have been reported.[30]
