  1. The Building / Fire Codes Kin Man Wong, M.Sc., P.Eng., CP

  2. BCBC 2006 / VBBL 2007 • Set out technical provisions for the design and construction of Buildings • new • alteration • change of use • demolition • Formulatedd based on NBC 2005 (2010)

  3. BCBC 2006 / VBBL 2007 • Address the following broad objectives • safety • health • accessibility • fire protection • environmental protection (VBBL) • Next BCBC revision in 2012

  4. BCFC 2006 / VFBL 2000 • Applicable to facilities other than buildings • Include following provisions • maintenance and use of fire safety and fire protection features • conduct of activities • limitations on hazardous contents • fire safety plan • fire safety at construction and demolition sites

  5. Objective-Based Code Format

  6. Objective vs Performance • Benchmark approach • BCBC 2006 Div. A Clause 1.2.1.1.(1)(b), “…that will achieve at least the minimum level of performance required by Div. B ….” • Qualitative • First principle approach • Quantitative

  7. Structure of the Codes • Division A • Part 1: Compliance • Part 2: Objective Statements • Safety • Health • Accessibility • Protection of buildings and facilities • Part 3: Functional Statements

  8. Structure of the Codes (cont’d) • Division B – Acceptable Solutions • Part 1: General • Part 2: (reserved) • Part 3: Fire Protection, Occupant Safety and Accessibility • Part 4: Structural Design • Part 5: Environmental Separation

  9. Structure of the Codes (cont’d) • Division B – Acceptable Solutions* • Part 6: HVAC • Part 7: Plumbing Services • Part 8: Safety Measures at Construction and Demolition Sites • Part 9: Housing and Small Buildings • Part 10 (VBBL): Existing Buildings • Division C – Administrative Provisions * Intent statements and Application statements

  10. Practitioners • Certified Professional • Building Code Consultant

  11. Certified Professional Program • Optional fast track projects through dedicated Registered Professional • Building Permit • Occupancy Permit • Only in participating municipalities • Vancouver, Surrey • Kelowna (?), Delta (?)

  12. Roles of CP • Retained by owner • Undertake plan reviews and field reviews on behalf of the AHJ with respect to “code co-ordination” • Issue CP letters of Assurance

  13. Areas of coordination by CP • Code coordination with Registered Professionals of record per Div. B parts 1 to 7 and relevant portions of part 9 • Code interpretation of Div. B parts 1, 2 and 3 • Through design stage, field review stage and occupancy stage

  14. Building Code Consultant • Specialist consultant to advise on Building Code conformance per Div. B (predominately parts 1, 2 and 3) • Develop Alternative Solutions based on Div. A

  15. Alternative Solution • DIVISION A • objectives • sub-objectives • functional requirements • DIVISION B • quantitative performance • criteria (minority) • basic acceptable solutions Alternative solution Mandatory Links

  16. An Example Building with Interconnected Floor Space (i.e. atrium)

  17. Interconnected Floor Space • noncombustible construction [3.2.8.3.(1)] • vestibules for exit stairs [3.2.8.5.(1)] • cumulative exit capacity [3.4.3.2.(6)] • mechanical venting (4 a.c./hr) [3.2.8.8.(1)] • draft stops [3.2.8.7.(1)] • smoke detectors [3.2.4.11.(1)(f)] • close spaced sprinklers [NFPA 13-1999 5-13.4] • combustible content limits [3.2.8.9.(1)]

  18. Alternative Solutions Fire Safety Engineering Approach

  19. Performance Criteria Division A Mitigating proposals Fire modelling/ TEA Meet Criteria? Alternative solution Develop Alternative Solution no yes

  20. Code Reference 1 Code Reference 2 Objective 1 Objective 2 Objective 3 Objective 4 Sub-objective A Sub-objective B Functional statement 01 Functional statement 02 AND gate Design Option meets code compliance requirements via alternative solution Performance criteria Performance criteria-2 Performance criteria-1

  21. Mitigating Measures • Sprinkler system • Enhanced reliability • Early warning system • Smoke detectors adjacent to interconnected floor spaces to activate alarm and smoke management system • Automatic smoke management system • Smoke exhaust and make up air supply • Power supply • Enhanced reliability

  22. Fire modelling /TEA • Fire Dynamic Simulator • Pathfinder

  23. Division B Acceptable Solution establishes the baseline level of performance RSET ASET Code conforming vestibules and cumulative exit stair widths incorporated

  24. Division A Alternative Solution to perform as well as or better than the Acceptable Solution RSET ASET
