Context: What Is The Code? The Building Code: Technical requirements for construction (including renovation) and demolition of buildings, change of use of existing buildings where the change would result in an increase in hazard and the maintenance and operation of on-site sewage systems. The Code : a set of minimum provisions with respect to the safety of buildings public health, fire protection, accessibility and It is a building owner s responsibility for life safety of the occupants of a building. Architects advise building owner s of the Building Code Requirements which are the : minimum requirements of the applicable codes and standards.

Course Objective To describe the Structure of the Ontario Building Code; Understand how to navigate through the Code; Code Matrix building code compliance data. Sample Code Matrix - new building, using Part 3 of the Building Code; Review key components of the Building Code.

ONTARIO BUILDING CODE 2012 STRUCTURE Division A: Part 1 Compliance and General Section 1.2 Compliance 1.2.1.1 Compliance with Division B 1. Compliance with Division B shall be achieved, (a) By complying with the applicable acceptable solutions in Division B, or (b) By using alternative solutions that will achieve the level of performance required by the applicable acceptable solutions in respect of the objectives and functional statements attributed to the applicable acceptable solutions in MMAH Supplementary Standard SA-1, Objectives and Functional Statements Attributed to the acceptable solutions.

ONTARIO BUILDING CODE 2012 STRUCTURE Division A: Part 2 : Objectives Division A: Part 3 : Functional Statements The 2012 Building Code is Ontario s second edition of the building code published in an objective-based format. Some of the objectives were developed jointly between the National Research Council (NRC) and the provinces. The objective-based format is intended to assist users of the code in the WHY behind code requirements. Intent statements although not available in a published format are intended to be available electronically (similar to Appendix A) - explaining the intent of the code item.

Objective Based Format: WHY? The objective-based format : Intended to Answer WHY????. I. Specific technical requirements identifies objectives and sub-objectives II. Each technical requirement has an acceptable solution in Division B and is linked to one or more of the objectives as well as functional statements III. OBC 2012-VOLUME 2 : Attribution tables : SA-1 (Supplementary Standard). IV. The objective based framework: a framework for evaluating alternative solutions against the performance achieved by the acceptable solutions set out in the Code. V.

Ontario Building Code 2012 Identification Building Code: Numbering System The Building Code uses a decimal numbering system has been used to identify particular requirements. Number Description 3 Part 3.6 Section 3.6.2 Subsection 3.6.2.3 Article 3.6.2.3.(1) Sentence 3.6.2.3.(1) (f) Clause 3.6.2.3.(1) (f) (i) Sub-clause 3.6.2.3.(1) (f) (i) (A) Sub-sub-clause

Ontario Building Code 2012 Measurement Building Code: Metric Conversions Metric System =Theofficial units of measurement in the Code. Sometimes imperial equivalence appears in brackets for convenience only. Part 9 - Housing and Small Buildings Part 7-Plumbing: Measurements converted to SI units where it is feasible, except for pipe sizes which are expressed in inches. Pipe Sizes = known in the trade in IMPERIAL

Ontario Building Code 2012 Wording Building Code: Wording: AND AND The word and found at the end of a second last clause of a sentence and with multiple clauses means that the requirements of every Clause apply to the sentence: Example: Article 3.3.1.17 reads: (1) Except as provided in Sentence (6) and Articles 3.3.28 and 3.3.4.7., a guard not less than 1 070 mm high shall be provided, a) Around each roof to which access is provided for other than maintenance, b) At opening into smoke shafts referred to in Subsection 3.2.6 that are less than 1 070 mm above the floor, and c) At each raised floor, mezzanine, balcony, gallery, interior or exterior vehicular ramp, and at other locations where the difference in level is more than 600 mm.

Ontario Building Code 2012 Wording Building Code: Wording: OR OR The word or found at the end of a second last clause of a sentence and with multiple clauses means requirements of Sentence is satisfied by any Clause as applied individually : Example: Article 3.3.1.9 Corridors reads: (11) A dead end public corridor is permitted in a business and personal services occupancy where, (a) The dead end corridor, (i) serves an occupant load of not more than 30 persons (ii) is not more than 9m long, and (iii) is provided with doors having self-closing devices, or b) There is a second and separate egress doorway from each room or suite not leading into a dead end corridor.

Ontario Building Code 2012 Wording Building Code: Wording: Rules The Code is structured into a number of Rules that apply without exception. Example: 9.1.1.3 Self Storage Buildings (1) self-service storage buildings shall conform to the requirements of Section 3.10.

Ontario Building Code 2012 Wording Building Code: Wording: Rules and Exceptions The Code is structured into a number of Rules that apply without exception. Other times the Code considers a general Rule, and then Exceptions as they apply. Example: 3.2.5.13 Automatic Sprinkler Systems (1) Except as permitted in Sentences (2), to (4) an automatic sprinkler system shall be designed, constructed, installed and tested in conformance with NFPA 13, Installation of Sprinkler Systems. (See Appendix A.) Reading sentences 2, 3, and/or 4 one determines that in particular cases one can design according to the direction provided in NFPA 13R, NFPA13D or if the design has fewer than 9 sprinklers then sentence 4 provides direction.

Ontario Building Code 2012 Application NEW BUILDING EXISTING BUILDING Reconstruction Renovation Alteration Extension Addition Change of Use

Ontario Building Code 2012 Application Renovations - can be repartitioning (office accommodation), interior work, or installing of new equipment. The Fire Code - a regulation made under the Fire Protection and Prevention Act, 1997. It is applicable to operations and maintenance. The Fire Code is a set of minimum requirements respecting fire safety within and around existing buildings and facilities. The owner is responsible for complying with the Fire Code, except where otherwise specified. The municipal fire department enforces the Fire Code.

Building Code Analysis Building Code Matrix Reference Project: Step 1: Identifying the Scope of the Project Questions to Ask:

Reference Project : Occupancy Classification: Table 3.1.2.1 Major Occupancy Classification (forming part of Sentences 3.1.2.1 (1), 3.1.2.2 (1) and 3.11.2.1 (3) Group Division Description of Major Occupancies A 1 Assembly occupancies intended for the production and viewing of the performing arts A 2 Assembly occupancies not elsewhere classified in Group A A 3 Assembly occupancies of the arena type A 4 Assembly occupancies in which occupants are gathered in the open air B 1 Detention occupancies B 2 Care and treatment occupancies B 3 Care occupancies C -- Residential occupancies D Business and personal services occupancies E - Mercantile occupancies F 1 High hazard industrial occupancies F 2 Medium hazard industrial occupancies F 3 Low hazard industrial occupancies

Building Code: Occupancy Classification Sentence 3.1.2.2 (1) Occupancies of the Same Classification Any building is deemed to be occupied by a single major occupancy not withstanding its use for more than one major occupancy, provided that all occupancies are classified as belonging to the same Group classification or, where the Group is divided into Divisions, as belonging to the same Division classification described in Table 3.1.2.1. Definitions: Building: Building Code 2012 missing from definitions but 2010 NBC Building: Building means any structure used or intended for supporting or sheltering any use or occupancy. Major occupancy: means the principal occupancy for which a building or part of a building is used or intended to be used, and is deemed to include the subsidiary occupancies that are an integral part of the principal occupancy.

Building Code: Occupancy Classification Definitions: Assembly Occupancy: (A1, A2, A3 and A4): the occupancy or use of a building or part of a building by a gathering of persons for civic, political, travel, religious, social, education, recreational or similar purposes or for the consumption of food or drink. A- Division 2 Church A- Division 1 Theatre

Building Code: Occupancy Classification Definitions: Detention Occupancy: Group B, Division 1 (B1): an occupancy in which persons are under restraint or are incapable of self preservation because of security measures not under their control. Care and Treatment Occupancy: Group B, Division 2 (B2): an occupancy in which persons receive special care and treatment. Care Occupancy: Group B, Division 3 (B3) : an occupancy in which special care is provided by a facility, directly through its staff or indirectly through another provider, to residents of the facility, (a) who require special care because of cognitive or physical limitations and (b) who as a result of those limitations, would be incapable of evacuating the occupancy, if necessary, without the assistance of another person. B Division 2 Home for the Aged B Division 3 Group Homes - Developmental Disabilities B Division 1 Prisons

Building Code: Occupancy Classification Definitions: Residential Occupancy: Group C: an occupancy in which sleeping accommodation is provided to residents who are not harboured for the purpose of receiving special care or treatment and are not involuntarily detained.

Building Code: Occupancy Classification Definitions: Business and Personal Service Occupancy: Group D: the occupancy or use of a building or part of a building for the transaction of business or the provision of professional or personal services

Building Code: Occupancy Classification Definitions: Mercantile Occupancy: Group E: the occupancy or use of a building or part of a building for the display or selling of retail goods, wares or merchandise

Building Code: Occupancy Classification Definitions: Industrial Occupancy: Group F: the occupancies or use of a building or part of a building for the assembling, fabricating, manufacturing, processing, repairing or storing of goods and materials Group F Division 1: High Hazard Industrial Occupancy Group F Division 2: Medium Hazard Industrial Occupancy Group F Division 3: Low Hazard Industrial Occupancy

Building Code: Major Occupancy Major Occupancy versus Subsidiary Occupancy: The definition of major occupancies does not prevent subsidiary occupancies in the building. The dividing line between a major occupancy and a subsidiary occupancy is not always black and white. Article 3.2.2.8: In a building in which the aggregate area of a major occupancies in a particular Group or Division is not more than 10% of the floor area of the storey in which they are located, these major occupancies need not be considered as major occupancies for the purpose of this Subsection, provided they are not classified as Group F, Division 1 or 2 occupancies. Morris Thuemen Architects Inc. Subsidiary Occupancy-an integral part of the principal Occupancy Major Occupancy: Occupancy A2: - School.

Building Code: Major Occupancy Major Occupancy + Major Occupancy +Major Occupancy + = HAZARDS = risk of exposure to fire. Certain major occupancies are to be isolated from others by fire separations, to protect one occupancy from the danger created by the other. (TABLE 3.1.3.1) Adjoining means above, beside or below. The plane of fire separation could be vertical or horizontal. Fire separations are intended to slow or prevent the spread of fire and smoke from where it begins in the building to another part, by applying principles of compartmentation. Article 3.1.3.2: certain occupancies do not require separations, but others in the building code discuss that they can t be in the same building with other occupancies Section 3.3: Tenancy, ownership has an influence on fire separations

Barrier Free Design : Includes: entrances, paths of travel; controls; washroom requirements, universal toilet room requirements, showers/bathtubs, shelves, counters for public telephones, and drinking fountains. Depending on client group they may be additional Client Group Barrier Free requirements. Various municipalities in Ontario have additional requirements. The federal government for example uses NBC 2010, and the technical standard CAN/CSA- B651-2004 (even though 2012 is printed). In 2005, the Ontario Government took a step towards building a more accessible province when it passed Accessibility for Ontarians With Disability Act (AODA). It calls for the development of standards for accessibility in five key areas of daily living: Customer Service, Information and Communications, Employment, Transportation and the Built Environment.

Building Code Barrier Free Design As of January 2012 the AODA Act, legally requires all organizations both public and private, that provide goods and services either directly to the public or to other organizations in Ontario (3 rd parties) and that have one or more employees to provide accessible customer service to persons of all levels. Ontario Building Code has been amended to include enhancements to accessibility in buildings. As of January 1, 2015, new construction and renovations are subject to updated accessibility requirements.

PT. 3 Practice Tip OAA Building Code Data Matrix Regulation 27 of the Architects Act requires that architects must when submitting an application of a building permit include, with the information that is submitted, building code compliance data. In practice: communication of code related data when applying for a building permit is a systematic approach : A Building code Matrix. Although there is no direction in the Code as to how to do this, the practice tip attempts to provide information on a suggested procedure. 1. A code matrix has become the practice. 2. Locate the information in a conspicuous place on the drawings. 3. The OAA provides a sample matrix. Generally this is expanded so that the matrix becomes useful through out the life of the project. We use it as a record of decisions made with respect to the Building Code 4. Adjust the code matrix for each project, and Record the Code version being used, i.e. 2006 to 2012-including the reference numbers 5. An adaptation of the matrix, can be made for other applicable codes, i.e. the National Building Code.
