Fire Protection Systems in the International Existing Building
Fire Protection Systems in the International Existing Building Code Jeffrey M. Hugo, CBO Director of Codes and Public Fire Protection National Fire Sprinkler Association Automatic Fire Alarm Association Basic Use of the IEBC The IEBC is made up of three different methods of achieving compliance. Repairs stand alone.
Each compliance method is unique. When a compliance method is chosen by designer, the code applies only to that method Automatic Fire Alarm Association Methods to Use in the IEBC 1. Prescriptive Method (Chapter 5) a) Comply with the IBC as new. 2. Work Area Method (Chapters 6-12) a) Scope of area where work is done a) Level 1 paper and paint
b) Level 2 reconfiguration of space c) Level 3 50% 3. Performance Method (Chapter 13) a) Points and values system Automatic Fire Alarm Association Who Gets to Pick the Method? Answer: The designer. The code official reviews, issues permits and enforces Chapter 3 is the hub of the code.
Points to the three methods Methods and specific requirements found in the methods are NOT combined or cherry-picked Automatic Fire Alarm Association Compliance Methods Provisions for all compliance methods Chapter 3 Prescriptive Method Chapter 5 Performance Method Chapter 13
Work Area Method Chapter 6: Classification Chapter 7: Alteration Level 1 Chapter 8: Alteration Level 2 Chapter 9: Alteration Level 3 Chapter 10: Change of Occupancy Chapter 11: Additions Chapter 12: Historic Buildings Automatic Fire Alarm Association What is a Work Area? The portion(s) of a
building consisting of all reconfigured spaces Work areas can be rooms, floors, entire wings or specific as walls, structural elements, ceiling, etc. Automatic Fire Alarm Association 1 2

Chapter 7: Alterations-Level 1 Level 1 Alterations: Removal and replacement or the covering of existing materials, elements, equipment, fixtures Using new materials, elements, equipment, fixtures That serve the same purpose. Automatic Fire Alarm Association
Chapter 7: Alterations-Level 1 Fire protection: Level 1 alterations shall be done in a manner that maintains the level of fire protection provided. Automatic Fire Alarm Association Chapter 8: Alterations-Level 2 Level 2 Alterations: Reconfiguration of space or
extension of any system Installation of any new equipment Addition of elimination of any door, or window Requirements contained in Level 1 Alterations apply. (Chapter 7) Work areas shall be noted on documents. Automatic Fire Alarm Association Alterations-Level 2:Rating Equivalency Correlates with IFC Section 1103.1 Fire resistance ratings can be
reduced, or eliminated to current IBC per code official approval NFPA 13 and NFPA 13R Requires a paper trail to justify the sprinklers. Automatic Fire Alarm Association Alterations-Level 2: Fire Protection Fire protection in Section 804 is: Limited to work area, or to extent specified, where Level 2 Alterations are performed.
Automatic Fire Alarm Association Alt Level 2: Fire Prot: Corridors When sprinklers are reqd throughout story Include floor stair landing and intermediate landing Corridor ratings are permitted to be reduced to IBC Automatic Fire Alarm Association Alt Level 2: Fire Protection
High Rise Work areas with exits or corridors serving an occupant load of 31+ OR more than one tenant: sufficient sprinkler water Automatic Fire Alarm Association Alt Level 2: Fire Protection A, B, E, I, M, R-1, R-2, R-4, F-1, S-1 & S-2 When work area >50% of floor area .If the building does not have sufficient municipal water supply for the design of a fire sprinkler system available to the
floor without installation of a new fire pump Automatic Fire Alarm Association Alternate Protection for Work Area Where sprinklers are NOT installed: Work areas have automatic smoke detection system throughout all occupied spaces other than sleeping units or individual dwelling units that activates the
occupant notification system Automatic Fire Alarm Association Alterations-Level 2: Fire Protection Other Required Fire Protection Systems Work area located in area per IBC Table 903.2.11.6 is required to be sprinklered... sufficient municipal water supply new fire pump
IFC Table 903.2.11.6 is also included Automatic Fire Alarm Association Alterations-Level 2: Fire Protection Supervision When sprinkler systems are required by the IEBC, the following supervision methods are acceptable, when installed in accordance with NFPA 72: 1. Central station 2. Proprietary 3. Remote station
4. Local alarm Automatic Fire Alarm Association Standpipe Exceptions No fire pump is required if FD can supply: Sprinklered throughout: 250 GPM @ 65 PSI to topmost floor. Unsprinklered building: 500 GPM @ 65 PSI to topmost floor. Flow and pressure are designed for topmost floor even when not extended to topmost floor.
Interconnection of standpipes not required Each standpipe requires a FDC Automatic Fire Alarm Association Alterations-Level 2: Fire Alarm Fire alarm system or alarm-notification in work area: Group E, I-1, I-2, I-3, R-1, R-2, R-4 Where sprinklered and connected to fire alarm system, heat detection not required. Automatic Fire Alarm Association
Chapter 9: Alterations-Level 3 Level 3 Alterations: Where work area exceeds 50% of building area. Requirements contained in Level 1 and 2 Alterations apply. (Chapter 7 and 8) Apply in all work areas regardless of shared corridors, exits, and occupant load: 803-Building Elements 804-Fire Protection 805-Means of Egress Work area shall be noted on documents. Automatic Fire Alarm Association
Chapter 9: Alterations-Level 3 Boiler and furnace rooms of I-1, I-2, I-4, R-1, R-2 and R-4 are enclosed by 1-hr rated construction. Sprinklered furnace rooms are exempt from 1-hr enclosure and enclosure. Automatic Fire Alarm Association Chapter 9: Alterations-Level 3 Fire sprinklers are required in: Groups: A, B, E, I, M, R-1, R-2, R-4, F-1, S-1 and S-2
Mixed uses Windowless stories Other required automatic sprinkler systems in Table 903.2.11.6. Regardless of shared corridors, exits, and occupant load Automatic Fire Alarm Association Alterations-Level 3: High Rise Fire sprinklers are provided in all work areas when the high rise has a sufficient
water supply for the design and installation at the site. Automatic Fire Alarm Association Alts-Level 3: Furniture & Mattresses Work areas with furniture or mattresses shall be sprinklered: F-1 occupancy exceeds 2,500 sf. M occupancy exceeds 5,000 sf. S-1 occupancy exceeds 2,500 sf. Threshold is based on size of occupancy, but application of sprinklers only in work area. I.E.: 8,000 sf M occupancy with a 3,000 sf work
area. Sprinklers are triggered because it exceeds 5,000, but only the 3,000 sf work area is sprinklered. Automatic Fire Alarm Association Alterations-Level 3: Fire Alarm Fire alarms and detection installed as if new construction. Manual alarms, if required as new, installed only in work area. Fire detection, if required as new, installed in work area. Automatic Fire Alarm Association
Repairs The 2018 IEBC addresses repairs in Chapter 4. Repair: The reconstruction or renewal of any part of an existing building for the purpose of its maintenance or to correct damage. Automatic Fire Alarm Association Chapter 4 - Repairs Fire protection Repairs to fire protection shall be done in a manner that maintains level of fire protection provided.
Examples: Fork truck hits galvanized pipe and in-rack sprinkler. Replace section of pipe, fitting, and sprinkler. Concealed sprinkler covers fell off and damaged. Replace with same or listed equivalents. Damaged corridor walls from carts? Lift damages painted pipe and recalled sprinkler? Automatic Fire Alarm Association Important Notes to Remember Three separate and distinct methods.
Work areas are designated and indicated by designer. Not code official Code official and designer sticks to chosen method. Fire protection thresholds and installation references from IEBC go through IBC. Automatic Fire Alarm Association Thank You Jeffrey M. Hugo, CBO Director, Codes & Public Fire Protection
