2. 44 states and the Department of Defense use the International Building Code 32 states use the International Residential Code 32 states use the International Fire Code

3. What are Building Codes? A building code is a collection of laws, regulations, ordinances or other statutory requirements adopted by a government legislative authority involved with the physical structure and healthful conditions for occupants of buildings. Building codes are the government's official statement on building safety.

4. Building Codes establish predictable and consistent minimum standards which are applied to the quality and durability of construction materials. "Minimum requirements" means that construction meets the criteria of being both "practical and adequate for protecting life, safety and welfare of the public".

5. So who needs building codes? We all need protection from tragedy due to fire, structural collapse and general deterioration in our homes, offices, schools, manufacturing facilities, stores or places of entertainment.

6. Building codes embrace all aspects of building construction - fire and structural items as well as the plumbing, electrical and mechanical systems. They provide safeguards and ensure uniformity in the construction industry

7. Inspection during construction is the only way to independently verify that compliance has been achieved. Inspections are conducted in homes, offices and factories to verify conformity to minimum standards, prior to the issuance of an occupancy certificate.

8. Building codes are adopted by a state or local government's legislative body, then enacted to regulate building construction within a particular jurisdiction. The primary purpose of a building code is to regulate new or proposed construction.

9. Building codes only apply to an existing building if the building undergoes reconstruction, rehabilitation or alteration, or if the occupancy of the existing building changes to a new occupancy level as defined by the building code.

10. Ancient History of Building Codes Building regulations date back to the beginning of recorded history. The Code of Hammurabi (2200 B.C.) Included a simple but effective building code provision; if an architect built a house so negligently that it fell down and killed the owner's son, then the architect's son was put to death.

11. History of Building Codes in the United States In early America, George Washington and Thomas Jefferson encouraged the development of building regulations to provide for minimum standards related to public health and safety.

12. At the turn of the century, the insurance industry developed what many consider to be modern building codes in response to major urban fires in the United States. The National Board of Fire Underwriters published its National Building Code in 1905 as a model code; that is, one that could be adopted by a locality.

13. During the early 1900's, model building codes were written by code enforcement officials of various communities with assistance from all segments of the building industry

14. BOCA Code In 1915, code enforcement officials met to discuss common problems and concerns. Out of these meetings came the formation of three organizations of code enforcement officials. The first of these organizations, known as Building Officials and Code Administrators (BOCA) International, Inc., was created in 1915 and represented code officials from eastern and Midwestern portions of the United States.

15. Testing agencies: provide valuable information used in developing code requirements The standards developed by the various organizations become a base for the codes in order to determine the quality of the material and the workmanship.

19. occupancy types occupancy type: described in terms of types: A: assembly B: business E: educational F: factory and industrial H: hazardous I: institutional M: mercantile R: residential storage U: utility

20. construction types: based on the fire resistance of building components Structural frame, interior and exterior bearing walls, floor and roof construction. Type I: the most fire resistive Type II: Type III: Type IV: Type V: the least fire resistive

21. building codes address nearly all aspects of the physical environment building codes address the performance of the physical environment, and include: structure finish materials mechanical systems plumbing electrical

28. The Great Chicago Fire 1871 A web site dedicated to the Chicago fire of 1871: http://www.chicagohs.org/fire/intro/gcf-index.html

29. The blaze began about 9 p.m. on Sunday, October 8, 1871. By midnight the fire had jumped the river's south branch and by 1:30 a.m., the business district was in flames. Shortly thereafter the fire raced northward across the main river.

30. The waterworks were evacuated although the tower was not badly damaged and still stands. During Monday the fire burned as far as Fullerton Avenue. Rainfall which started about midnight helped put out the last of the flames. 300 Chicagoans were dead, 90,000 homeless, and the property loss was $200 million.

31. Boston Fire of 1872

33. In 1872 a burgeoning Boston, fat and complacent in the post–Civil War boom, ignored warnings that the city was growing too fast, too soon. The result was the Great Fire of 1872, a conflagration that left the commercial district in ashes and reshaped the city’s downtown.

34. building fires can be intense, difficult to extinguish, and very, very frightening

37. a house fire

38. Americans with Disabilities Act ADA The ADA is a federal code, with jurisdiction over the entire country. ADA code web site: http://www.access-board.gov/adaag/html/adaag.htm#4.1

40. an example of an ADA compliant ramp: the incline can be no steeper than 1:12

41. this restroom is ADA compliant because: the hot water pipes are shielded, the size of the room is sufficient for a wheelchair bound person to turn around, the faucet handles are automatic; no hand operations are needed to turn on and off the water.

42. fireplaces and chimneys

45. in a traditional fireplace most of the heat from the fire goes straight up the chimney

46. the fire chamber has to be lined with special fire resistant brick to resist the high heat of the fire

49. wood burning stoves wood must be carried in, ignited, and then ashes must be cleaned out
