Chapter 1: About the Codes

Keep in Mind.... 

Not all of the codes, standards and regulations you read about will be enforced in every code jurisdiction.  The local jurisdiction will decide which code and publication to use.  Some standards my not be required, but you might want to follow them to meet Health, Safety and Welfare concerns.  Federal regulations are the only regulations that are consistent in every jurisdiction. They are mandatory because they are the law.

The Code of Hammurabi is a black diorite stone, seven and a half feet in height and six feet in circumference. It was discovered by J. De Morgan and V. Scheil during their excavations at Susa, the Edomite capital, in 1901-2. The fiftyone columns of cuneiform text was written in the Akkadian (Semitic) language. The top of the stele has an engraved picture of Shamash, the sun god, seated on a throne handing a scepter and ring to Hammurabi. This is to symbolize the divine origin of the great code of laws which king Hammurabi received. This picture would reinforce the motivation for keeping these laws.

The document was over 300 paragraphs long and included sections on social, moral, religious, commercial and civil law. Kings of the day would post large monuments listing their laws with an accompanying statue carving of themselves to identify the law with the king. Hammurabi was no different in this practice. There were many copies of this law erected throughout the kingdom. Usually in the temples dedicated to the local gods. It now resides in the Louve, in Paris.



The code of Hammurabi made the builder accountable for the houses he built. If one of his buildings fell down and killed someone, the builder would be put to death.



First on record was in 1625 in what was know as New Amsterdam (New York).  Addressed fire prevention and governed the types of roofing materials that could be used to protect from chimney sparks.  Chicago fire of 1871 caused many large cities to create their own municipal building codes.



1905 Recommended Building Code, helped create the three original model codes



1973, congress passed the Consumer Product Safety Act and formed the Consumer Product Safety Commission. It’s goal is to prevent the necessity of federal regulations by encouraging industry selfregulation and standardization. This created a number of new standards-writing organizations not affiliated with the federal government. (NFPA, ANSI)

 A collection of regulations, ordinances, and other statutory requirements put together by various organizations. Once adopted by each jurisdiction, they become law. They are enforced on a local level and sometimes state level  They provide for a minimum level of performance, adequate standards of practice and uniformity of workmanship.



Ensure public health and safety throughout a building.  Most have come into play “after-the-fact” as a learning experience from a major tragedy.  They are primarily concerned with o Construction requirements

o Hazardous materials or equipment used in the building o 75% of all codes and standards deal with fire o Energy conservation o Accessibility



National Building Code (NBC)

published by

BOCA (Building Officials Code Administration



Standard Building Code (SBC)



Uniform Building Code (UBC)

published by Southern Building Code Congress International (SBCCI) published by the International Conference of Building Officials (ICBO)

  

Published by the International Code Council First established in 1994 and published in 2000. Most current edition is 2012 with a new edition expected in 2015.  Legacy codes are no longer being updated. IBC is updated every 3 years.  Some MS Jurisdictions adopted the code in 2003.  This code has now replaced the three model codes.



At the start of every project, what code and which edition of the code is being enforced in the jurisdiction of your project.

   

California: earthquakes Northern states: freezing temperatures South: hurricanes, tornados The IBC has incorporated these differences into one manual.

  

Common Code Format (page 16) Started in 1994 Organizes each of the codes into a similar format to include (See table, page 20)

o Chapter titles o Chapter content o Sequence of chapters



Life Safety Codes are organized by occupancy classification

  

Tells you the precise requirements such as the height of a handrail Most existing codes are prescriptive Performance based codes will not replace prescriptive codes. They will only apply to a part of a project.



New to the IBC  In the past, codes were typically very descriptive, indicating a precise requirement.  The code will specify the goal that should be met but not provide a specific description as to how that must be achieved. This allows for more creative design solutions.

   

ICC and NFPA now include fire codes. IFC International Fire Code UFC Uniform Fire Code (NFPA 1 ®) These address building conditions in relation to hazardous conditions that could cause a fire or explosion.  Designers will address chapters on: o Means of Egress o Interior Finishes o Furnishing and Decorative Materials

   

One of the first codes published by NFPA. Revised every 3 years 2003, 2006, 2009, 2012 and 2015 versions It is NOT a building code. It focuses on removal or evacuation of all persons from a building by protecting them from fire, smoke and toxic fumes.  Uses the Manual Style Format. First section concentrates on broad topics, description of occupancies, means of egress and fire protection  Second part is divided into chapters by occupancy type for new and existing buildings



Most widely used fire code  43 states adopted statewide - some jurisdictions in all states.  Some cities and states have stricter fire codes: Boston, California, Massachusetts, New Jersey and New York  Verify with your jurisdiction which Fire Codes are required and the edition that is currently adopted.



In the past, all three codes had their own plumbing code  International Plumbing Code (IPC) is updated every 3 years  When designing an interior, you may refer to this code to help determine the number of fixtures required for your project.

 

Now a part of the International Mechanical Code (IMC) As a designer, you will rarely refer to this code

    

National Electrical Code (NEC) Most widely used Published by NFPA Latest editions are 2011, 2014, 2017 You will rarely refer to this code

   



Both ICC and NFPA have energy conservation codes ICC: International Energy Conservation Code (IECC) (2009) NFPA: NFPA 900 Building Energy Code (BEC) All states must have energy codes in place that are at least as strict as the 2004 edition of IECC. MS adopted ASHRAE 90.1 2010



When designing the interior, the energy codes will include  requirements to maximize the amount of daylight  Minimize the lighting densities  Require the use of occupant-sensing controls.  They also cover the design, selection, and installation of energy-efficient mechanical systems, water-heating systems, electrical distribution systems and illumination systems.

Sustainability Codes      



Fairly new concept in the US These codes focus on how the building affects the environment Some energy codes address sustainability Some plumbing codes address water-efficiency Some states require rating systems such as LEED. California was the first state to develop a comprehensive sustainability code - California Green Building Standards Code (CGBSC) ICC has developed the International Green Construction Code (IGCC)

 

International Residential Code (IRC) First available in 1998  Based on the former One-and TwoFamily Dwelling Code  More current editions are 2012 and 2015  Applies to construction of single family, duplex and townhouses



 

The building codes and the Life Safety Code (LSC) dedicates an entire chapter to existing buildings. ICC published most current edition: 2009 and 2013 Verify if the IEBC (International Existing Building Code) is adopted in your jurisdiction.



A number of federal agencies and departments work with trade associations, private companies and the general public to develop federal laws for building construction



 

These regulations are published in the Federal Register (FR) and the Code of Federal Regulations (CFR) Published daily, but not all rules are enforceable laws Once they have been passed into law, they are published in the CFR annually.

 



The federal government regulates its own buildings. Federal buildings have their own regulations and do not use state or model codes. (VA hospitals, military bases, etc) They can pass federal legislation creating a law that supersedes all other state and local codes and standards. The ADA is an example.

  

Developed by the Dept. of Justice 4-part federal legislation become law on th July 26 , 1990. Enforceable in 1992 and 1993.



Is a comprehensive civil rights law that protects individuals with disabilities in the area of

o Employment (Title 1) o State and Local gov’t services and

transportation (Title II) o Public accommodations and commercial facilities (Title III) o Telecommunications (Title IV)



Any facility that offers public accommodation such as commercial facilities as well as business that offer food, merchandise or services to the public must follow this regulation  It is published in the Americans with Disabilities Act Accessibility Guidelines (ADAAG)  ANSI A117.1 is another accessibility guideline (see page 32) ADA may not be the only accessibility guidelines you have to follow.

   



Federal legislation enforced by the Dept. of Housing and Urban Development (HUD) Protects the consumer from discrimination in housing when buying or renting Pertains to housing with four or more dwelling units As of 1991, these buildings must have accessible public and common areas and ground floor units must be accessible and meet specific construction requirements. The FHA is often considered the residential version of the ADA.

 

OSHA Passed in 1970 to protect the American employee in the work place.  It regulates the design of buildings and interior projects where people are employed.  Employer must furnish a safe working environment or can be fined.  It also stresses the safe installation of materials and equipment to ensure the safety of construction workers.



A standard is a definition, a recommended practice, a test method, a classification, or a required specification that must be met.



They have no legal standing until they become referenced in a code which is adopted by a jurisdiction.



Many are developed by independent standards-writing organizations  Some are developed by government agencies  Trade associations



National Fire Protection Association (NFPA)  American National Standards Institute American Society for Testing and Materials (ASTM)  Underwriters Laboratories (UL)  Business and Institutional Furniture Manufacturers Association (BIFMA)

  



American National Standards Institute is a private corporation founded in 1918. Coordinates voluntary standards. Does not develop standards, but rather approves the standards developed by other organizations Most common standard for designers is ANSI A117.1



One of the largest standards organizations  Develops a wide variety of standards for fire protection.  They test textiles to fire fighting equipment to means of egress design  Many of the standards are referenced in the LSC and the NEC  ie: NFPA 701



   

American Society for Testing and Materials was formed in 1898 as a nonprofit corporation In 2002 became know as ASTM International Oversees the development of standards but does not actually perform the tests. These standards are used to help specify materials and assure quality ASTM E-84 (Steiner Tunnel Test)



A testing agency that approves products such as building materials, upholstered furniture (systems furniture), electrical products  Approved products will carry the UL mark



Codes set the minimum criteria. You can follow stricter requirements at any time.  They are not always perfectly clear. When two requirements are similar, go with the strictest requirement  Not all of them will apply to every design situation.  Work with the code official to resolve discrepancies.
