ICC CODE DEVELOPMENT CYCLE ERRATA TO THE PROPOSED CHANGES

2004-2005 ICC CODE DEVELOPMENT CYCLE ERRATA TO THE 2004/2005 PROPOSED CHANGES TO THE INTERNATIONAL CODES 2nd Posting: February 3, 2005 1st Posting: January 21, 2005 The following is a list of errata to the published monograph entitled “2004/2005 Proposed Changes to the 2003 Editions of the International Codes.” The first posting of the errata, January 21, 2005 starts on page 13. Additional errata were posted on the website on February 3, 2005. Each errata posting, February 3, 2005 and January 21, 2005 is organized based on the order of codes as published in Volumes 1 and 2. NOTE: A complete consolidated version of this errata, and any additional errata received, will be provided at the Code Change Hearings in Cincinnati. February 3, 2005 REVISIONS TO TENTATIVE ORDER OF DISCUSSION VOLUME 1: IBC GENERAL: IBC STRUCTURAL: VOLUME 2: FIRE CODE: RESIDENTIAL CODE - BUILDING: Add F262-04/05 after F146-04/05 Add RB239-04/05 after FS169-04/05, Part II Add RB240-04/05 after S157-04/05 Add RB241-04/05 after RB29-04/05 Add RB242-04/05 after S192-04/05 Add RB243-04/05 after RB40-04/05 Add RB244-04/05 after RB64-04/05 Add RB245-04/05 after RB90-04/05 Add RB246-04/05 after RB101-04/05 Add S32, Part II after RB34-04/05 Add G200-04/05 after G27-04/05 Add G201-04/05 after G200-04/05 After S32-04/05 add Part I -1- IBC GENERAL (VOLUME 1) G200-04/05: Add the following code change: G200-04/05 302.2.1, 303.1 Proponent: Carroll Lee Pruitt, AIA, Pruitt Associates, Arlington, TX 302.2.1 Assembly areas. Accessory assembly areas are not considered separate occupancies if the floor area is equal to or less than 750 square feet (69.7 m2). Assembly areas that are accessory to Group E are not considered separate occupancies. Accessory religious educational rooms and religious auditoriums with occupant loads of less than 100 are not considered separate occupancies. 303.1 Assembly Group A. Assembly Group A occupancy includes, among others, the use of a building or structure, or a portion thereof, for the gathering together of persons for purposes such as civic, social or religious functions, recreation, food or drink consumption or awaiting transportation. A room or space used for assembly purposes by less than 50 persons and accessory to another occupancy shall be included as a part of that occupancy. Assembly areas with less than 750 square feet (69.7 m2) and which are accessory to another occupancy according to Section 302.2.1 are not assembly occupancies. Assembly occupancies which are accessory to Group E in accordance with Section 302.2 are not considered assembly occupancies. Religious educational rooms and religious auditoriums which are accessory to churches in accordance with Section 302.2 and which have occupant loads of less than 100 shall be classified as A-3. Assembly occupancies shall include the following: A1 through A5 (No change to current text) Reason: Religious educational rooms and religious auditoriums with occupant loads of less than 100 are by definition a Group A-3 occupancies and thus the code language is not necessary. Cost Impact: None Public Hearing: Committee: Assembly: AS AM ASF AMF D DF G201-04/05 302.2.1, 303.1 Proponent: Carroll Lee Pruitt, AIA, Pruitt Associates, Arlington, TX 302.2.1 302.3 Assembly areas. Accessory assembly areas are not considered separate occupancies if the floor area is equal to or less than 750 square feet (69.7 m2). Assembly areas that are accessory to Group E are not considered separate occupancies. Accessory religious educational rooms and religious auditoriums with occupant loads of less than 100 are not considered separate occupancies. 303.1 Assembly Group A. Assembly Group A occupancy includes, among others, the use of a building or structure, or a portion thereof, for the gathering together of persons for purposes such as civic, social or religious functions, recreation, food or drink consumption or awaiting transportation. A room or space used for assembly purposes by less than 50 persons and accessory to another occupancy shall be included as a part of that occupancy. Assembly areas with less than 750 square feet (69.7 m2) and which are accessory to another occupancy according to Section 302.2.1 302.3 are not assembly occupancies. Assembly occupancies which are accessory to Group E in accordance with Section 302.2 are not considered assembly occupancies. Religious educational rooms and religious auditoriums which are accessory to churches in accordance with -2- Section 302.2 and which have occupant loads of less than 100 shall be classified as A-3. Assembly occupancies shall include the following: A1 through A5 (No change to current text) Reason: The code change in 2001 that relocated this language from the footnote in Table 302.3.2 to the new and revised section numbers was intended to simply make the footnote more aware to the code user. However, the code change confused the issue with the requirements for accessory use in Section 302.2. This code change takes the code back to the requirements of the 2000 IBC as the proponent of the previous code change intended.

Rossberg, P.E., Structural Engineering Institute of ASCE, Reston, VA, representing Structural Engineering Institute of ASCE and the NCSEA Code Advisory Committee THIS CODE CHANGE IS ON THE AGENDA OF THE IBC STRUCTURAL AND THE IRC CODE DEVELOPMENT COMMITTEES. SEE THE TENTATIVE HEARING ORDERS FOR THESE COMMITTEES. PART II - IRC Revise as follows: R301.2.1.3 Wind speed conversion. When referenced documents are based on fastest mile wind speeds, the three second gust basic wind velocities speeds, V3S,of Figure R301.2(4) shall be converted to fastest mile wind velocities speeds, Vfm, using Table R301.2.1.3 or Equation XXX. V fm = (V 3S - 10.5)/1.05 Equation XXX) Where: V 3S = 3 second gust basic wind speed from Figure R301.2.

Linear interpolation is permitted. R301.2.1.4 Exposure category. For each wind direction considered, an exposure category that adequately reflects the characteristics of ground surface irregularities shall be determined for the site at which the building or structure is to be constructed. For a site located in the transition zone between categories, the category resulting in the largest wind forces shall apply. Account shall be taken of variations in ground surface roughness that arise from natural topography and vegetation as well as from constructed features. For any given wind direction, the exposure in which a specific building or other structure is sited shall be assessed as being one of the following categories: (Exposure A-D description relocated and revised in Section R301.2.1.4.3) R301.2.1.4.1 Wind directions and sectors. For each selected wind direction at which the wind loads are to be evaluated, the exposure of the building or structure shall be determined for the two upwind sectors extending 45 degrees either side of the selected wind direction. The exposures in these two sectors shall be determined in accordance with Sections 301.2.1.4.2 and 301.2.1.4.3 and the exposure resulting in the highest wind loads shall be used to represent winds from that direction. -4- R301.2.1.4.2 Surface roughness categories. A ground surface roughness within each 45-degree sector shall be determined for a distance upwind of the site as defined in Section 301.2.1.4.3 from the categories defined below, for the purpose of assigning an exposure category as defined in Section 301.2.1.4.3. Surface Roughness B: Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstruction having the size of single-family dwellings or larger. Surface Roughness C: Open terrain with scattered obstructions having heights generally les than 30 ft (9.1 m). This category includes flat open country, grasslands, and all water surfaces in hurricane-prone regions. Surface Roughness D: Flat, unobstructed areas and water surfaces outside hurricane-prone regions. This category includes smooth mud flats, salt flats and unbroken ice. R301.2.1.4.3 Exposure Categories. An exposure category shall be determined in accordance with the following: 1. Exposure A. Large city centers with at least 50 percent of the buildings having a height in excess of 70 feet (21 336 mm). Use of this exposure category shall be limited to those areas for which terrain representative of Exposure A prevails in the upwind direction for a distance of at least 0.5 mile (0.8 km) or 10 times the height of the building or other structure, whichever is greater. Possible channeling effects or increased velocity pressures due to the building or structure being located in the wake of adjacent buildings shall be taken into account. 2. Exposure B. Urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions having the size of single–family dwellings or larger. Exposure B shall be assumed unless the site meets the definition of another type exposure. Exposure B shall apply where the ground surface roughness condition, as defined by Surface Roughness B, prevails in the upwind direction for a distance of at least 2630 feet (800 m) or 10 times the height of the building, whichever is greater. Exception: For buildings whose mean roof height is less than or equal to 30 feet (9.1 m), the upwind distance shall be permitted to be reduced to 1500 feet (457 m). 3. Exposure C. Open terrain with scattered obstructions, including surface undulations or other irregularities, having heights generally less than 30 feet (9144 mm) extending more than 1,500 feet (457 m) from the building site in any quadrant. This exposure shall also apply to any building located within Exposure B type terrain where the building is directly adjacent to open areas of Exposure C type terrain in any quadrant for a distance of more than 600 feet (183 m). This category includes flat open country, grasslands and shorelines in hurricane prone regions. Exposure C shall apply for all cases where Exposures B or D do not apply. 4. Exposure D. Flat, unobstructed areas exposed to wind flowing over open water (excluding shorelines in hurricane prone regions) for a distance of at least 1 mile (1.61 km). Shorelines in Exposure D include inland waterways, the Great Lakes and coastal areas of California, Oregon, Washington and Alaska. This exposure shall apply only to those buildings and other structures exposed to the wind coming from over the water. Exposure D extends inland from the shoreline a distance of 1,500 feet (457 m) or 10 times the height of the building or structure, whichever is greater. Exposure D shall apply where the ground surface roughness, as defined by Surface Roughness D, prevails in the upwind direction for distance of at least 5000 ft (1524 m) or 10 times the height of the building, whichever is greater. Exposure D shall extend inland from the shoreline for a distance of 660 ft (200 m) or 10 times the height of the building, whichever is greater. Reason: (Part II) R301.2.1.3 This table was originally derived from the Durst curve depicted in Figure C6.1 of ASCE 7-98. For the 2002 edition of ASCE 7, the curve was replotted to more closely reflect the original work of C. S. Durst in 1960. This resulted in the new curve of Figure C6-2 of ASCE 7-02. Slight changes in the replotted curve cause changes in conversion wind speeds. In addition, the manner in which the original conversions were made for the 2000 IBC (from fastest-mile to 3-second gust rather than vice versa) resulted in the values of fastest mile wind speeds being unconversative (lower than they should be). It was felt that in addition to -5- having a table with conversion wind speeds, it would be advantageous to give an equation that allows conversion wind speed to be calculated. The following table illustrates the unconservative nature of the conversion values in the existing table. V Calculated V fm 2003 IBC & IRC V fm Underdesign with present tablea 3% 3% 11% 11% 10% 8% 7% 7% 5% 5% 4% 3% 3% 3-sec 85 90 100 105 110 120 125 130 140 145 150 160 170 71 76 85 90 95 104 109 114 123 128 133 142 152 70 75 80 85 90 100 105 110 120 125 130 140 150 a. Equals (V fm IBC/IRC ÷ V fm calculated)2, which represents how using a velocity that is too lower affects the design wind pressure. For example, the existing table gives the fastest mile wind speed of 80 mph for a 3-second gust speed of 100 mph. While the 5 mph increase being proposed may seem to be small, this translates into an increase of approximately 13% in the design wind pressure ((85/80)^2 = 1.129). Stated differently, the 5 mph error now contained in the code results in the design wind pressure being approximately 11.4% less than it should be. (Part II) R301.2.1.4: The purpose of this portion of the code change is to update the wind exposure category definitions in the IRC to be consistent with the definitions that exist in ASCE 7-02 and that will be in ASCE 7-05. Several revisions were made to the exposure definitions in the ASCE 7-02 edition. A summary of the changes is provided below: 1. Exposure A has been deleted. Exposure A was intended to be used for dense city centers with tall buildings. However, the ASCE Committee has concluded that in areas in close proximity to tall buildings the variability of the wind is too great, because of local channeling and wake buffeting effects, to allow a special category A to be defined. A wind tunnel test is recommended where schedule and cost permit, in dense city centers. 2. A distinction has been made between surface roughness categories and exposure categories. This enables more precise definitions of Exposures B, C, and D. 3. The exposure for each wind direction is defined as the worst case of the two 45-degree sectors either side of the wind direction being considered. 4. Interpolation between exposure categories is now permitted.

Clark, County of Fairfax, VA, representing Ray Pylant, Building Official Revise as follows: 907.2.9 (Supp) Group R-2. A manual fire alarm system shall be installed in Group R-2 occupancies. where: 1. Any dwelling unit or sleeping unit is located three or more stories above the lowest level of exit discharge; 2. Any dwelling unit or sleeping unit is located more than one story below the highest level of exit discharge of exits serving the dwelling unit or sleeping unit; or 3. The building contains more than 16 dwelling units or sleeping units. Exceptions: 1. A fire alarm system is not required in buildings not more than two stories in height where all dwelling units or sleeping units and contiguous attic and crawl spaces are separated from each other and public or common areas by at least 1-hour fire partitions and each dwelling unit or sleeping unit has an exit directly to a public way, exit court or yard. 2. Manual fire alarm boxes are not required throughout the building when the following conditions are met: 2.1. The building is equipped throughout with an automatic sprinkler system in accordance with Section 903.3.1.1 or Section 903.3.1.2; and The notification appliances will activate upon sprinkler flow. 2.2. 3. A fire alarm system is not required in buildings that do not have interior corridors serving dwelling units and are protected by an approved automatic sprinkler system installed in accordance with Section 903.3.1.1 or 903.3.1.2, provided that dwelling units either have a means of egress door opening directly to an exterior exit access that leads directly to the exits or are served by open-ended corridors designed in accordance with Section 1022.6, Exception 4. Reason: Several recent fires in Fairfax County, Va. have brought out the dangers of rapid fire spread in low-rise wood structures with contemporary cladding. In the most recent fire, rapid fire extension on the outside of a first floor porch led to fire spread simultaneously up the exterior and through the units after window breakage and wall penetration. The result was three deaths and one serious injury to residents on the third floor, two floors above the seat of the fire. Lack of a building wide alarm system contributed to the delay in exiting. While in-unit detectors were present, some occupants said they went off and were heard, while others said they did not hear them. In-unit detectors are not designed to inform occupants on the third or other floors of a rapidly-developing fire. The limitations as previously written for Section 907.2.9 Group R-2, allowed multi-family dwellings, four stories or less, to eliminate the need for alarm notification. Deleting these limitations will require the structures to provide an audible alarm activated either by water flow of a single sprinkler or one pull of the alarm to alert occupants throughout the building. Providing alarm notification devices will alert occupants of fire spread and allow for rapid exiting of the building thus eliminating the tragic results that were sited earlier. Cost Impact: This code change will increase the cost of construction.

Walls shall be defined as follows: Load–bearing wall is a wall supporting any vertical load in addition to its own weight. Nonbearing wall is a wall which does not support vertical loads other than its own weight. WALL, LOAD BEARING. Any wall meeting either of the following classifications: 1. Any metal or wood stud wall that supports more than 100 pounds per linear foot (plf) (1459 N/m) of vertical load in addition to its own weight. 2. Any masonry or concrete wall that supports more than 200 plf (2919 N/m) of vertical load in addition to its own weight. WALL, NONLOAD BEARING. Any wall that is not a load-bearing wall. Reason: Reference IBC 2003, Section 16 Definitions for consistency in definition. It is important to maintain conformity in definitions between International Codes to reduce confusion. The information and headings in Table 2308.9.1 and R602/3(5) Size, Height and Spacing of Wood Studs is identical, therefore the definition of a load-bearing and a non-load-bearing wall should be identical. Cost Impact: None Public Hearing: Committee Assembly: AS ASF AM D AMF DF RB240-04/05: Add the following code change: RB240-04/05 R301.1 Proponent: Joseph Knarich, National Association of Home Builders, Washington D.C. Revise as follows: R301.1 Design Application. Buildings and structures, and all parts thereof, shall be constructed to safely support all loads, including dead loads, live loads, roof loads, flood loads, snow loads, wind loads and seismic loads as prescribed by this code. The construction of buildings and structures in accordance with the provisions of this code shall result in a system that provides a complete load path capable of that meets all requirements for the transfer of transferring all loads from their point of origin through the load–resisting elements to the foundation. Reason: The proposed change to the title of the section makes it consistent with other similar sections of the code. The modification to the language clarifies that a structure built to the provisions of the code meets the basic requirements for the transference of the loads listed in the section to the foundation. This change is needed because the current language and title has been interpreted to -8- require design of structures and/or components as well as justification that the loads are transferred, instead of stating that a structure constructed to the prescriptive requirements meets all requirements for all necessary load transfer. Cost Impact: None Public Hearing: Committee Assembly: AS ASF AM D AMF DF RB241-04/05: Add the following code change: RB241-04/05 R301.2.1.1 Proponent: Charles B. Clark, Jr., Brick Industry Association, Reston, VA, representing Masonry Alliance for Codes and Standards Revise as follows: R301.2.1.1 Design criteria. Construction in regions where the basic wind speeds from Figure R301.2(4) equal or exceed 110 miles per hour (177.1 km/h) shall be designed in accordance with one of the following: 1. American Forest and Paper Association (AF&PA) Wood Frame Construction Manual for One– and Two–Family Dwellings (WFCM); or 2. Southern Building Code Congress International Standard for Hurricane Resistant Residential Construction (SSTD 10); or 3. Minimum Design Loads for Buildings and Other Structures (ASCE–7); or 4. American Iron and Steel Institute (AISI), Standard for Cold–Formed Steel Framing—Prescriptive Method for One– and Two–family Dwellings (COFS/PM). 5. Concrete and masonry construction shall be designed in accordance with the provisions of this code. Reason: This section of the code specifically outlines which standards can be used to design construction in areas where wind speeds exceed 110 miles per hour. This change would refer the user directly from this section to those masonry standards recognized by the code as acceptable. While this standard is already incorporated into the code, it would allow a direct reference to the masonry veneer provisions within the standard which address designing for wind speeds exceeding 110 miles per hour. Cost Impact: None Public Hearing: Committee Assembly: AS ASF AM D AMF DF RB242-04/05: Add the following code change: RB242-04/05 R301.2.2.2.1 Proponent: Joseph Knarich, National Association of Home Builders, Washington, D.C. Revise as follows: R301.2.2.2.1 Weights of materials. Average dead loads shall not exceed 15 psf (0.72 kN/m2) for roofs/ceiling assemblies or 10 15 psf (0.48 0.72 kN/m2) for floor assemblies, except as further limited by Section R301.2.2. Dead loads for walls above grade shall not exceed: -9- 1. Fifteen psf (0.72 kN/m2) for exterior light–frame wood walls. 2. Fourteen psf (0.67 kN/m2) for exterior light–frame cold–formed steel walls. 3. Ten psf (0.48 kN/m2) for interior light–frame wood walls. 4. Five psf (0.24 kN/m2) for interior light–frame cold–formed steel walls. 5. Eighty psf (3.83 kN/m2) for 8–inch–thick (203 mm) masonry walls. 6. Eighty–five psf (4.07 kN/m2) for 6–inch–thick (152 mm) concrete walls. Exception: Roof/ceiling dead loads not exceeding 25 psf (1.19 kN/m2) shall be permitted provided the wall bracing amounts in Chapter 6 are increased in accordance with Table R301.2.2.2.1. Reason: From an investigation into minimum recommended dead loads in ASCE 7, we have found that several flooring materials have dead loads that exceed 10 psf, yet are common in one- and two-family dwelling construction. Materials such as slate and tile on mortar have loads that would be covered under the increased loads, but would not adversely affect the overall performance of the structure.

Conformity between codes and standards creates less confusion in the construction industry. The following are the formulas from IBC 1607.11.2 (see also ASCE 7, 7.4.9.1): R2 = 1 for F# 4 R2 = 1.2 – 0.05 F for 4 < F < 12 R2 = 0.6 for $ F = 12 Cost Impact: None (Equation 16-28) (Equation 16-29) (Equation 16-30) - 10 - Public Hearing: Committee Assembly: AS ASF AM D AMF DF RB244-04/05: Add the following code change: RB244-04/05 R309.2 Proponent: Charles B. Clark, Jr., Brick Industry Association, Reston, VA, representing Masonry Alliance for Codes and Standards Revise as follows: R309.2 (Supp) Separation required. The garage shall be separated from the residence and its attic area by not less than 1/2-inch (12.7 mm) gypsum board applied to the garage side. Garages beneath habitable rooms shall be separated from all habitable rooms above by not less than 5/8-inch (15.9 mm) Type X gypsum board or equivalent. Where the separation is a floor-ceiling assembly, the structure supporting the separation shall also be protected by not less than 1/2-inch (12.7 mm) gypsum board or equivalent. Garages located less than 3 feet (914 mm) from a dwelling unit on the same lot shall be protected with not less than 1/2-inch (12.7 mm) gypsum board applied to the interior side of exterior walls that are within this area. Openings in these walls shall be regulated by Section R309.1. This provision does not apply to garage walls that are perpendicular to the adjacent dwelling unit wall or walls constructed of concrete or masonry. Reason: This is a follow-up to code change RB56-03/04 which added ½ inch gypsum board to the interior side of garage walls where they were located less than 3 feet from adjacent dwellings. It is not necessary to add gypsum board to concrete or masonry walls to increase its fire resistance since all concrete and masonry walls used as a garage wall will have the minimum fire resistance required without it. Cost Impact: None Public Hearing: Committee Assembly: AS ASF AM D AMF DF RB245-04/05: Add the following code change: RB245-04/05 R314.2.6 Proponent: Jay Murdoch, Owens Corning, Bethesda, Maryland, representing Owens Corning Basement Finishing System R314.2.6 Interior trim. Foam plastic trim defined as picture molds, chair rails, baseboards, handrails, ceiling beams, door trim and window trim may be installed, provided: 1. The minimum density is 20 pounds per cubic foot (3.14 kg/m3). 2. The maximum thickness of the trim is 0.5 inch (12.7 mm) and the maximum width is 4 8 inches (102 204 mm). 3. The trim constitutes no more than 10 percent of the area of any wall or ceiling. The interior trim shall not constitute more than 10 percent of the aggregate wall and ceiling area of any room or space. 4. The flame–spread rating does not exceed 75 when tested per ASTM E 84. The smoke–developed rating is not limited. Reason: This is correlation to the International Building Code (Section 2604.2). The IBC permits a maximum 8-inch width for plastic trims (see 2604.2.2 Thickness), and bases the 10 percent area limitation on the wall and ceiling area (see 2604.2.3 Area limitation). - 11 - Cost Impact: None Public Hearing: Committee Assembly: AS ASF AM D AMF DF RB246-04/05: Add the following code change: RB246-04/05 R319.3, Chapter 43 Proponent: Randall Shackelford, Simpson Strong-Tie Co., McKinney, TX 1. Revise as follows: R319.3 Fasteners. Fasteners for pressure preservative and fire–retardant–treated wood shall be of hot–dipped galvanized or mechanically galvanized steel, stainless steel, silicon bronze or copper. Hot dipped galvanizing shall be in accordance with ASTM A153. Mechanical galvanizing shall be in accordance with ASTM B695, Class 50 minimum. Exception: One–half–inch (12.7 mm) diameter or greater steel bolts. 2. Add standard to Chapter 43 as follows: ASTM B695-00 Standard Specification for Coatings of Zinc Mechanically Deposited On Iron and Steel . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . R319.3 Reason: This change is to introduce some minimum standards for galvanizing fasteners that will be in contact with treated wood. The current wording allows minimal galvanizing which might not be effective. This also coordinates with S61-03/04 that added the ASTM A153 standard to the IBC. It also adds in an alternate method for galvanizing, mechanical galvanizing, which is preferable for some types of fasteners. Class 55 provides for an equivalent amount of zinc as would be provided by hot dipping in accordance with ASTM A153. According to the American Galvanizers Associaiton, mechanical plating to a thickness of 55 microns provides an equivalent coating to 1 oz/sq. ft. of hot-dipped galvanized zinc, which is what is provided for fasteners by ASTM A 153. Class 55 provides 55 microns of thickness.

Klein & Associates, Eldersburg, MD Delete without substitution: SECTION 3104 PEDESTRIAN WALKWAYS AND TUNNELS - 19 - 3104.10 Tunneled walkway: Separation between the tunneled walkway and the building to which it is connected shall not be less than 2-hour fire-resistant construction and openings therein shall be protected in accordance with Table 715.3. 3104.11 Ventilation. Smoke and heat vents shall be provided for enclosed walkways and tunneled walkways as required for Group F-1 occupancies in accordance with Section 910. Reason: Section 3104.11 is based on an antiquated requirement that dates back to the 1968 edition of the Standard Building Code (SBC Section 516, “Covered Malls, Walkways And Tunnels”). This requirement was based on most buildings being nonsprinklered because the Standard Building Code required very few uses to be sprinklered. Walkways and tunnels built under the old SBC Section 516 did not require sprinklers, only separation from the connected buildings, and smoke & heat vents per NFPA 204. In the IBC Code today, almost all buildings that would use Section 3104 requirements, are sprinklered. In addition, tunnels, by way of the sprinkler requirements of IBC Section 903.2.10.1.3 (“Basements”), would most certainly be required to be sprinklered. Such common place sprinklering of buildings and tunnels was never envisioned back in 1968 when SBC Section 518 was introduced in the Code. The other two legacy codes, UBC & BOCA, developed their walkway requirements based on adequate building separations between the connecting buildings (with appropriate exceptions for sprinklers) and control of the contents within the walkway, but saw no need for the requirement for smoke and heat vents. Numerous building connections throughout the US have been built to those two codes’ requirements with no adverse fire or life safety problems. Section 3104 on “Pedestrian Walkways & Tunnels” was in the original working draft of the IBC. The IBC subcommittee that drafted this section of Code combined the requirements from the three legacy codes. Based on my research of the original legacy code development cycles, the original requirements were developed as follows: • UBC Section 409 “Pedestrian Walkways”. This new section in the 1985 edition of the UBC was the results of Code Proposal 509-81-1 (Proponent: San Joaquin Valley Chapter) during the ICBO Code Development Cycles from 1982-1984. • BOCA Section 3106 “Pedestrian Walkways” This new section (was originally new Section 514) in the 1990 edition of the BNC was the result of Code Proposals B29-88 and B43-89 (Proponent for both: John W. McCormick, P.E. representing Rolf Jensen & Associates) during the BOCA Code Development Cycles from 1988-1989. • SBC Section 3104 “Covered and Enclosed Walkways and Tunnels” This new section (was originally new Section 516, “Covered Malls, Walkways And Tunnels”) in the 1968 edition of the SBC was the result of Committee Action Item #8 (Proponent: American Institute of Timber Construction & National Forest Products Association) during the SBCCI Code Development Cycles from 1965-1967. It is reasonable to assume that most walkways designed under the old SBC were open, not enclosed, walkways because of the warmer weather conditions and the added costs imposed by the requirement for smoke and heat vents. However, in the northeast and western sections of the US where the UBC and BOCA Codes were used and where the weather conditions are usually harsher, most walkways were enclosed for the comfort of the pedestrians using them. Based on all the other requirements for pedestrian walkways and tunnels under Sections 3104.1 through 3104.10, the requirement for heat and smoke vents is expensive with little, if any, life safety benefit. Given the IBC Code requirements for walkways that cover the limitations on contents permitted in these walkways, and the fire separation from the connected buildings, walkways are no more of a fire hazard than an exit access corridor designed under Section 1016. Since numerous walkways between buildings have been built throughout the US to the past editions of the UBC and BOCA requirements with no adverse fire or life safety problems, the added requirement for smoke and heat vents for walkways under IBC Section 3104.11 should be deleted from the Code as an unnecessary requirement.

SEE THE TENTATIVE HEARING ORDER FOR THE IBC STRUCTURAL CODE DEVELOPMENT COMMITTEE. Revise as follows: 3403.2.3 Seismic. Additions, alterations, modification, or change of occupancy of existing buildings shall be in accordance with this section for the purposes of seismic considerations. 3403.2.3.1 1614.1.1 Additions to existing buildings. An addition that is structurally independent from an existing structure shall be designed and constructed as required for a new structure in accordance with the seismic requirements for new structures. An addition that is not structurally independent from an existing structure shall be designed and constructed such that the entire structure conforms to the seismic-force resistance requirements for new structures unless the following conditions are satisfied: 1. The addition conforms with the requirements for new structures, 2. The addition does not increase the seismic forces in any structural element of the existing structure by more than 10 5 percent, unless the element has the capacity to resist the increased forces determined in accordance with ASCE 7 Sections 1613 through 1622, and 3. Additions do not decrease the seismic resistance of any structural element of the existing structure by more than 10 5 percent cumulative since the original construction, unless the element has the capacity to resist the forces determined in accordance with ASCE 7 Sections 1613 through 1622. 3403.2.3.2 1614.3 Alterations. Alterations are permitted to be made to any structure without requiring the structure to comply with Section Sections 1613 through 1623 provided the alterations conform to the requirements for a new structure. Alterations that increase the seismic force in any existing structural element by more than 10 5 percent or decrease the design strength of any existing structural element to resist seismic forces by more than 10 5 percent shall not be permitted unless the entire seismic-force-resisting system is determined to conform to ASCE 7 Sections 1613 through 1623 for a new structure. Exception: Alterations to existing structural elements or additions of new structural elements that are not required by ASCE 7 Sections 1613 through 1623 and are initiated for the purpose of increasing the strength or stiffness of the seismic-force-resisting system of an existing structure need not be designed for forces conforming to ASCE 7 Sections 1613 through 1623 provided that an engineering analysis is submitted indicating the following: 1. The design strength of existing structural elements required to resist seismic forces is not reduced. 2. The seismic force to required existing structural elements is not increased beyond their design strength. 3. New structural elements are detailed and connected to the existing structural elements as required by this chapter Chapter 16. 4. New or relocated nonstructural elements are detailed and connected to existing or new structural elements as required by this chapter Chapter 16. 5. The alterations do not create a structural irregularity as defined in ASCE 7 Section 1616.5 or make an existing structural irregularity more severe. 6. The alterations do not result in the creation of an unsafe condition. 3406.4 1614.2 Change of occupancy. When a change of occupancy results in a structure being reclassified to a higher occupancy category seismic use group, the structure shall conform to the seismic requirements for a new structure. Exceptions: 1. Specific seismic detailing requirements provisions required of this code or ASCE 7 for a new structure - 21 - shall are not be required to be met where it can be shown that the level of performance and seismic safety is an equivalent to that of level of performance and seismic safety contemplated for a new structure is obtained. Such analysis shall consider the regularity, overstrength, redundancy and ductility of the structure within the context of the existing and retrofit (if any) of the specific detailing provided. 2. When a change of use results in a structure being reclassified from Occupancy Category I or II Seismic Use Group I to Seismic Use Group II to Occupancy Category III and the structure is located in a seismic map area where S DS < 0.33, compliance with the seismic requirements of this code and ASCE 7 this section is not required. CHAPTER 35 REFERENCED STANDARDS ASCE/SEI 7—05 Minimum Design Loads for Buildings and Other Structures Reason: The purpose of this change is to relocate the seismic provisions contained in Chapter 16 that pertain to existing buildings to Chapter 34 as this appears to be the appropriate chapter and make the relocated provisions consistent with Appendix 11B of the 2005 edition of ASCE 7-05 which is proposed to be adopted by reference It is also proposed that the limit at which the entire structure must comply with the seismic provisions for new structures be increased from 5% to 10%. It is felt that the setting the limitation level at 5% is overly restrictive and results in a substantial increase in expense for only minimal improvement in the seismic performance of the completed structure. In proposing to adopt ASCE 7-05 by reference it should be noted that as of the submission date of this code change, August 20, 2004, the ASCE 7 Standards Committee is in the final stages of completing the 2005 edition of ASCE/SEI 7. The document is designated ASCE/SEI 7-05 Minimum Design Loads for Buildings and Other Structures and it is expected that the document will be printed and available for purchase from prior to the hearings. Any person interested in obtaining a pre-publication copy of ASCE/SEI 7-05 may do so by contacting Jim Rossberg, ASCE, 1801 Alexander Bell Drive, Reston, VA 20191-4400, 703-295-6196, jrossberg@asce.org.

Cost Impact: None Public Hearing: Committee: Assembly: AS ASF AM AMF D DF G198-04/05: Add the following code change: G198-04/05 310.2 Proponent: Daniel Weed, City of Thornton, CO Add new definition as follows: TRANSIENT. Occupancy of a dwelling unit or sleeping unit for not more than 30 days. Reason: The intention of this new definition is to give the code user a time parameter to differentiate between transient and nontransient as listed within Section 310.1, R-1 and R-2. Currently there is no code language that prevents a hotel or motel from being called an R-2 instead of an R-1. Webster’s dictionary says that transient is temporary, and the code has set a precedent in Section 410.2 where it says that temporary platforms shall only exist for 30 days. Other code references to 180 days being temporary certainly seem an excessive amount of time for the occupant to become familiar with the surroundings. Real estate law dictates that a lease must be created after 30 days, and 30 day time periods are typically how extended-stay hotels and motels rent to people. Such a time period should give the occupant time to be familiar with the surroundings, and therefore be more used to any hazards of the built environment than an overnight guest would be or a guest who stays for just a few days. Since nontransient occupancies do not have the same level of protection in the code as transient occupancies, it seems important to determine what makes an occupancy “transient” so as to provide consistency in enforcement.

Note: The references to NASPEC in the code text will also be changed to NAS. - 24 - ENERGY CODE (VOLUME 2) EC16-04/05: Add the following proponent to the proposal from Craig Conner: Ed Reeves, Icynene, Inc. (Submitted identical proposal with different reason as shown below) Reason: (Reason from Ed Reeves) The increases in frame wall R-value in IECC Table 402.1 exclude viable and competitive products from the insulation market in violation of the IECC’s stated intent. “The intent of the code is to provide flexibility to permit the use of innovative approaches and techniques to achieve effective utilization of energy” (2003 IECC Section 101.2). “The provisions of the code are not intended to prevent the use of any material” (2003 IECC Section 103.1). The IECC requirements for wood-frame walls should be restored to the R-value recommended by DOE as indicated above. Specification of R-15 and R-21 wall insulation is problematic. Many insulation products achieve an R-13 in a 2x4 wall; however, specifying R-15 borders on specifying “fiberglass or closed cell foam”. The Icynene Insulation System® has an R-value of 3.6 per inch of thickness. A 2x4 wall has a 3.5" cavity that allows for an Icynene® total R-value of 13. Other established insulation materials such as cellulose and open celled foam plastic insulation would also be eliminated as well. Likewise, a 2x6 wall has a 5.5" cavity that allows for an Icynene® R-value of 20, but would not meet the R-21 requirement. Several other viable foam products are similarly disadvantaged. The benefits of Icynene’s® air sealing ability greatly exceed the benefits of an increase of 2 in R-value. Further, the air sealing is a more cost effective method of improving the energy efficiency of a wall than purchasing the more costly premium product R-15 batt insulation. As an example, a REM/Design energy analysis for a building in Chicago illustrates the importance of air sealing compared to a small increase in R-value. Increasing the building envelope R-value from R-13 to R-15 with an air permeable insulation yields a 2% savings in heating costs and a 0.5% savings in cooling cost. However, with R-13 Icynene® in the building envelope, the annual energy cost savings are over 35% greater than R-15 air permeable insulation. Likewise, the air seal advantage also allows R-19 Icynene® to provide superior energy performance over an R-21 air permeable insulation. The change in wall insulation requirements is incomplete, leaving inconsistencies in the code. The amendment modified only one of the four tables that specify wall insulation. The amendment modified only the prescriptive R-value table in the IECC, but did not make corresponding changes in the IRC’s R-value table (Table N1102.1) or the associated U-value requirements (IECC Table 402.1.2 and IRC Table N1102.1.2). The simplest way to fix this inconsistency is to restore the IECC Table 402.1 as proposed herein and originally proposed by DOE. Icynene Inc. strongly recommends that the wood-frame wall R-values in Table 402.1 be returned to the R-values originally proposed by DOE as shown above. - 25 - FIRE CODE (VOLUME 2) Replace the Fire Code Committee listing with the following new list: Gene Boecker, RA Project Manager Code Consultants, Inc.

PART III — IRC Revise as follows: M1307.4 Hydrogen generating and refueling operations. Ventilation shall be required in accordance with Section M1307.4.1, M1307.4.2 or M1307.4.3 in public garages, private garages, repair garages, automotive service stations and parking garages which that contain hydrogen-generating appliances or refueling systems. Such spaces shall be used for the storage of not more than three hydrogen-fueled passenger motor vehicles and have a floor area not exceeding 850 square feet (79 m2). The maximum rated output capacity of hydrogengenerating appliances shall not exceed 4 standard cubic feet per minute (ft3/min) of hydrogen for each 250 square feet (23.2 m2) of floor area in such spaces. For the purpose of this section, rooms or spaces that are not part of the living space of a dwelling unit and that communicate directly with a private garage through openings shall be considered to be part of the private garage. M1307.4.1 Natural ventilation. Indoor locations intended for hydrogen-generating or refueling operations shall be limited to a maximum floor area of 850 square feet (79 m2) and shall communicate with the outdoors in accordance with Sections M1307.4.1.1 through M1307.4.1.2.

In such locations, equipment and appliances having an ignition source shall be located such that the source of ignition is not less than within 12 inches (305 mm) below of the ceiling. - 29 - M1307.4.1.1 Two openings. Two permanent openings, shall be provided within the garage. The upper opening shall be one located entirely within 12 inches (305 mm) of the ceiling of the garage,. The lower opening shall be and one located entirely within 12 inches (305 mm) of the floor of the garage,. Both openings shall be provided in the same exterior wall. The openings shall communicate directly with the outdoors. Each opening shall directly communicate with the outdoors horizontally, and shall have a minimum free area of 1/2 square foot per 1,000 cubic feet (1 m2/610 m3) of garage volume. M1307.4.2 Mechanical ventilation. Indoor locations intended for hydrogen-generating or refueling operations shall be ventilated in accordance with Section 502.16 of the International Mechanical Code. In such locations, equipment and appliances having an ignition source shall be located such that the source of ignition is below the mechanical ventilation outlet(s). Reason: Without revision, the current wording has the effect of limiting the number of hydrogen-fueled vehicles stored in such occupancies to three. Rather than restricting the number of vehicles stored, it is the intent that the refueling area be limited both in size (i.e., 850 square feet) and number of vehicles (i.e., three) being refueled. Additionally it was felt that improvements to the sentence structure of the Sections (IFGC 703.1.1.1, IMC 304.4.1.1, IRC M1307.4.1.1) which describe the location and size of the openings will improve interpretation and enforcement. No other technical revisions have been made. Analysis: Contrary to the reason statement, the revised text does not limit the number of vehicles being refueled to three.

Dahmen, P.E., Wisconsin Licensed Commercial Building Inspector, representing himself M11-04/05: Replace the proponent’s reason with the following: Reason: This is a much needed provision to permit such use of the permanent equipment only when the manufacturer provides the option. Central furnaces tested to ANSI Z21.47 are required to address in their instruction manual the subject of temporary heating of buildings under construction. The manufacturer may or may not allow such use and if allowed, specific instructions must be followed to prevent unsafe conditions and damage to the appliance. M35-04/05: Add an analysis statement to read as follows: Analysis: The maintenance of the technical content of the text being deleted by this proposal rests with the International Fire Code Development Committee. The need for and suitability of duplicating that IFC text in the IMC is a matter to be determined by the International Mechanical Code Development Committee. Identical text also appears in IMC Section 511.2 and it is unclear why it was not also included in this proposal. M38-04/05: Revise the proposal to read as follows: M38-04/05 IFC 2211.7.1 (IMC [F]502.16) Proponent: Shahriar Amiri, Montgomery County, MD, representing Maryland Building Officials Association (MBOA) THIS PROPOSAL IS ON THE AGENDA OF THE IFC CODE CHANGE COMMITTEE. PLEASE CONSULT THE HEARING ORDER OF THE IFC CODE CHANGE COMMITTEE. Revise as follows: IFC 2211.7.1 Ventilation. Repair garages used for the repair of natural gas- or hydrogen-fueled vehicles shall be provided with an approved mechanical ventilation system. The mechanical ventilation system shall be in accordance with the International Mechanical Code and Sections 2211.7.1.1 and 2211.7.1.2. Exception: Repair garages with natural ventilation when approved. IMC [F] 502.16 Repair garages for natural gas- and hydrogen-fueled vehicles. Repair garages used for the repair of natural gas- or hydrogen-fueled vehicles shall be provided with an approved mechanical ventilation system. The mechanical ventilation system shall be in accordance with Sections 502.16.1 and 502.16.2. Exception: Where approved by the code official, natural ventilation shall be permitted in lieu of mechanical ventilation. Reason: The exception is being removed because there are no guidelines as to when natural ventilation may be utilized. Also there are two natural ventilation systems available in the Code. Chapter 4 of the IMC describes the requirements for natural ventilation of a given space. Chapter 7 of the IFGC contains natural ventilation measures for hydrogen-generating and refueling operations. It is not certain if the IFGC provisions can be applied to natural-gas-fired vehicles. On a technical front, provisions of the IMC and IFGC are quite different. Additional investigation must be done before an exception of this magnitude can be given as part of the code. - 31 - Cost Impact: None Public Hearing: Committee: AS AM Assembly: ASF AMF D DF M99-04/05: Revise the analysis statement to read as follows: Analysis: Section 101.2 of the IMC states that the scope of the IMC includes maintenance of mechanical systems that are permanently installed. The maintenance of the technical content of the text being deleted by this proposal rests with the International Fire Code Development Committee. The need for and suitability of duplicating that IFC text in the IMC is a matter to be determined by the International Mechanical Code Development Committee. - 32 - PROPERTY MAINTENANCE CODE (VOLUME 2) PM14-04/05: Add new code change as follows: PM14-04/05 404.5 Proponent: Dave Walls, California Department of Housing and Community Development, Sacramento, CA 404.5 (Supp) Overcrowding. The number of persons occupying a dwelling unit shall not create conditions that, in the opinion of the building official, endanger the life, health, safety or welfare of the occupants. Every bedroom occupied by two persons shall contain at least 70 square feet (6.5 m 2) of floor area, and every bedroom occupied by more than two persons shall contain 50 square feet (4.6 m2) of floor area for each additional occupant thereof. Reason: The current IPMC section 404.5 could greatly increase housing construction costs, will create significant housing code occupancy enforcement costs, and may be inconsistent with the Federal Fair Housing Act Amendments and interpretations thereof. The current standard permits local jurisdictions to interpret the section based on individual means and understandings, which creates a lack of uniformity in enforcement. STANDARD OCCUPANCIES: The UBC contained the same 70 square foot minimum size for many years, and the UHC permitted t w o persons to sleep in the minimum sized sleeping room for many years. The standard sleeping arrangement of two persons should be permitted; however, an interpretation by a building official may believe this endangers life, health, or the welfare of its occupants and lesson this typical family arrangement. As the CODE ENFORCEMENT ISSUES: At least all of the jurisdictions which adopted the ICBO UHC, and other jurisdictions as well, have allowed two persons sleeping together in 70 square foot bedrooms, with an additional person allowed with each additional 50 square feet of bedroom space. Without local amendments, building officials must enforce the current standard. The 2000 U.S. Census Statistics show that this could impact 2,143,735 owner-occupied households and 3,914,155 renter-occupied units which have greater than 1 occupant per room, if building officials were to take a more stringent interpretation of the codes. [“Occupants per room” is obtained by dividing the number of people in each occupied housing unit by the number of rooms (including living rooms, dining rooms, kitchens, bedrooms, etc.) in the unit. According to the 2000 US Census, 49.8% of owner-occupied households are in three-bedroom units, 38.5% of renter-occupied households are in two-bedroom units, and 15.2% of all units have greater than one occupant per room, with an average household size of 2.87. INCREASED GOVERNMENT COST OF MODEL CODE USE: If jurisdictions adopt the IPMC as a reference code, they would seek to avoid negative impacts of an inappropriate rule. Otherwise, they will incur the costs of changing an existing standard, require unnecessary construction costs, incur new enforcement costs, and raise resident and/or landlord compliance issues. With the IPMC as written, state and local governments will have to adopt and distribute an amendment to this section of the IPMC, incur those unnecessary costs and assume the impact of distribution of information necessary to clarify this issue and/or clarify enforcement issues. FHAA ISSUES: The Fair Housing Act safe harbor related to familial discrimination is the “two persons per bedroom plus one” rule. A building official choosing to limit the number of persons to less than the FHAA, creates uncertainty for landlords seeking to comply with the safe harbor rule. Analysis: The committee needs to make its intent clear with respect to Section 404.5 as it relates to this proposal and PM9-04/05. Cost Impact: None Public Hearing: Committee: AS AM Assembly: ASF AMF D DF - 33 - RESIDENTIAL CODE (VOLUME 2) RB20-04/05: Insert the following figure at the end of the reason statement: RB84-04/05: Replace the entire reason statement with the following: Reason: Remove a redundant requirement as alarms are required within each bedroom. Moreover, it would be virtually impossible to enforce this requirement. RB86-03/04: Add table to reason statement as follows: Reason: The purpose of this code change is to improve the protection of lives and property in one- and two-family dwellings. Over the past several years, close to 60% of all structure fires have occurred in one- and two-family dwellings and have accounted for the vast majority of civilian deaths, civilian injuries, and property damage (see table below). And because of the large occurrence of one- and two-family dwelling fires, they have also accounted for the majority of firefighter injuries and deaths. From the period 1994-1998, 71% of firefighter fireground injuries occurred at residential occupancy fires (all types included). From the period 1994-2003, 117 firefighter fatalities occurred at one- and two-family dwelling fires, representing 42% of all fireground deaths at structure fires. These familiar residential fire statistics have helped the United States to continue to have one of the worst fire histories of the industrialized world. For years, so many reports and studies from the National Fire Protection Association, United States Fire Administration, Home Fire Sprinkler Coalition, and many others have found that fire sprinklers protecting a home can be one of the most effective ways to help address the residential fire problem. Progressive cities and fire departments have mandated sprinklers in homes and found remarkable results, showing significantly less deaths, injuries, fire damage, water damage, and installation costs. These positive results can be found in the extensive analysis completed in Scottsdale, Arizona. But the Scottsdale study was completed almost a decade ago and still only about 2% of homes are protected by sprinklers and still our nation resists this life-saving technology. The time has come, and is long overdue, to accept the challenge of this code change proposal and declare that it is no longer acceptable to make the home one of the more dangerous places to be. - 34 - References: 1.

RB215-04/05: Add the following ACCA standard to the code change: ACCA Air Conditioning Contractors of America 2800 Shirlington Road, Suite 300 Arlington, VA 22206 Standard Reference Number Manual J-2002 2004 Title Residential Load Calculation - Eighth Edition RB231-04/05: Add the following code change: RB231-04/05 R308.4 Proponent: Tom Rubottom, City of Lakewood, CO, representing Colorado Chapter of the ICC R308.4 (Supp) Hazardous locations. The following shall be considered specific hazardous locations for the purposes of glazing: 1. through 11. (No change to current text) Exception: The following products, materials and uses are exempt from the above hazardous locations: 1. through 3. (No change to current text) 4. Glazing in Section R308.4, Item 6, in walls perpendicular to the plane of the door in a closed position, other than the wall towards which the door swings when opened, or where access through the door is to a closet or storage area 3 feet (914 mm) or less in depth. Glazing in these applications shall - 35 - comply with Section R308.4, Item 7. 5. through 9. (No change to current text) Reason: Code change S81-01 brought back the exception #3 to IBC Section 2406.2 Hazardous locations. The proponent Ed Sutton with the National Association of Home Builders made a case that the perpendicular wall (other than the wall that door swings to when opened) with glazing has a much lower risk of problems since that exception was limited to residential applications where a much smaller number of occupants are likely to use a door at the same time. One error in the Code change monograph is that staff wrote in bold letters “This proposal achieves technical consistency between the IRC and the IBC.” In reality there still is not consistency between the 2 codes unless the committee approves this particular code change. When a door swings open to a perpendicular wall with glazing within 24”, it is very possible that the door could slam into the wall and break the glass or the door knob would hit the glass and break it. There is also the possibility that someone could be caught behind the door when it is opened and they would be pushed into/through the glass. This would be an appropriate area to have the required safety glazing to protect the occupants from falling sheets of glass. Cost Impact: None Public Hearing: Committee: AS Assembly: ASF AM AMF D DF RB232-04/05: Add the following code change: RB232-04/05 R311.1 Proponent: Rick Davidson, City of Hopkins, MN R311.1 General. Stairways, ramps, exterior exit balconies, hallways and doors shall comply with this section. Exception: Stairs and ladders used to access attics, crawl spaces, and storage spaces or used to attend equipment are exempt from the requirements of this section. Reason: Often there is a need to provide a stair to access a basement, attic or similar space but the area to provide a code compliant stair is not available, headroom cannot be maintained, or the frequency of use does not warrant full compliance. A good example of this is the pull down stair sometimes used to access a garage attic. Another example may be a ships ladder used to access a crawl space. These types of stairs are used only by the homeowner or a service person and are used infrequently. They pose little danger and are much more practical than a full stair. The former UBC provided a similar exception for stairs attending equipment. This code change will help provide direction to the user and to code enforcement. It will also help create uniformity with regards to this issue. Cost Impact: None Public Hearing: Committee: AS Assembly: ASF AM AMF D DF RB233-04/05: Add the following code change: RB233-04/05 R320.4 Proponent: Todd Bergstrom, AFM Corp., Burnsville, MN R320.4 Foam plastic protection. In areas where the probability of termite infestation is moderate to heavy or “very heavy” as indicated in Figure R301.2(6), extruded and expanded polystyrene, polyisocyanurate and other foam plastics shall not be installed on the exterior face or under interior or exterior foundation walls or slab foundations located below grade. The clearance between foam plastics installed above grade and exposed earth shall be at least 6 inches (152 mm). - 36 - Exceptions: 1. Buildings where the structural members of walls, floors, ceilings and roofs are entirely of noncombustible materials or pressure preservatively treated wood. 2. When in addition to the requirements of R320.1, an approved method of protecting the foam plastic and structure from subterranean termite damage is provided. 3. On the interior side of basement walls. Reason: Foam plastics have been reported to be damaged by termites in regions beyond the "very heavy" exposure. In order to protect homeowners, this use also should be limited in regions of "moderate to heavy" termite exposure.

General Requirements of ASME/ANSI A112.19.8M - 39 - 3109.5.3 Methods of entrapment avoidance. Entrapment avoidance of fully submerged suction outlets can be achieved by one of the following methods: 3109.5.3.1 Dual Drains. A minimum of two (2) suction outlets shall be provided for each pump or pumps in the suction outlet system, separated by a minimum of three feet (3') [91.44 cm] measured from center to center of suction pipes or located on two (2) different planes; i.e. one (1) on the bottom and one (1) on the vertical wall, or one (1) each on two (2) separate vertical walls. These suction outlets shall be plumbed such that water is drawn through them simultaneously through a common line to the Pump(s). Each suction outlet fitting shall be rated for the maximum system flow. 3109.5.3.2 Channel Drain System. One or more channel grates shall be acceptable as protection against suction entrapment if they are 3 inches or greater in width and 31 inches or greater in length and fastened to prevent removal as specified in ASME/ANSI A112.19.8M 3109.5.3.3 Gravity flow system. A Gravity Flow system shall be acceptable as protection against suction entrapment if it has one or more submerged suction outlet(s) with approved cover/grates in any combination fed by gravity into a collection tank vented to atmosphere. However, a modulating float valve allowing direct suction is not permitted. 3109.5.3.4 Combination Inlet/Outlet Fixtures for Swim Jets. Combination Inlet/Outlet Fixtures shall be acceptable as protection against suction entrapment for a Swim Jet system not related to the filtration system if they are manufactured and have their own dedicated pump(s) and the suction outlet and the return are located in a single fitting. 3109.5.3.5 Venturi Debris Removal Systems. Venturi Debris Removal Systems shall be acceptable as protection against suction entrapment if they are intended to remove debris through a single, floor mount suction outlet where low pressure is created by the entrainment of water within a deck mount canister that is not directly or indirectly connected to a pump’s suction. The single suction outlet shall have an approved cover/grate. 3109.5.4 Shallow Water Suction Outlets. Where all suction fittings are located less than 24 inches below normal operating water level, one of the following shall be required. 1. 2. 3. 4. gravity flow system one (1) additional drain vent system to atmosphere suction vacuum release device tested and approved for the purpose by a nationally recognized testing laboratory in accordance with ASME A112.19.17. 3109.5.5 Wall Vacuum Fittings. Where provided, the vacuum cleaner fitting(s) shall be located in an accessible position(s) at least 6 inches and no greater than 18 inches below the water level and shall comply with IAPMO SPS 4. 2. Add new text as follows: CHAPTER 35 REFERENCED STANDARDS IAPMO SPS 4 – 2000 Special Use Suction Fittings for swimming Pools, Spas and Hot tubs (for suction side automatic swimming pool cleaners). . . . . . . . . . . . . . . . . . . . . . . . . . . . 3109.5.5 Reason: Restrictions on Technology Current language eliminates some entrapment avoidance technology, which is otherwise approved under standards currently referenced in Sections AG106.3, Item 1 and 3109.5.2, Item 1. Intrinsically safe overflow systems It is often technically feasible to achieve sanitization and circulation without submerged suction outlets (drains) which are now required, unnecessarily mandating a potential hazard. Recognized Hazard Drain covers 12” X 12” or larger are currently exempt from testing even though there are documented injuries and a fatality involving their structural failure, including structural failure in combination with a SVRS. They should be eliminated as a single suction source. Justification for removing the term “Atmospheric”. This is a confusing term intended to describe several different - 40 - systems: gravity flow, vent pipe and Safety Vacuum Release Devices (Systems) (SVRS) as defined by ASME/ANSI A112.19.17. However the use of the term “atmospheric” prohibits the use of SVRS devices that turn off the pump electrical power or reverse the flow instead of allowing air into the suction piping. Emergency Power Shutdown Systems have counterparts in many other applications, such as circuit breakers, GFCI protected outlets and gas stations. Therefore, it is a disservice to the pool industry and future pool owners to prohibit this technology via the current code language of AG106.3 and 3109.5.2, “Atmospheric Vacuum Relief System Required.” Justification for requiring approved safety covers in all sizes. The current language of Sections AG106.3 and 3109.5.1 Suction Fittings, “All Pool and Spa suction outlets shall be provided with a cover that conforms with ANSI/ASME A112.19.8M, or a 12"X 12" drain grate or larger…,” exempts large drain covers from the approval process and this creates a dangerous loophole that permits the use of drains not intended by the manufacturer for all applications, specifically direct suction applications where the cover may be subjected to the full differential pressure capabilities of the pump. The US Consumer Product Safety Commission has published three (3) Epidemiologic Investigation Reports relating to injuries and a death in which one of the exempted large covers failed structurally under direct suction loading and it is believed that if the installer had been required to use approved covers intended for the application, the structural failures would not have occurred. Additionally, there is a May 27, 2003 report out of Fort Bliss, TX of a large, exempted drain cover failing structurally during the installation and testing of a Safety Vacuum Release System (SVRS), therefore a vacuum breaker backup does not eliminate the need for all drain fittings and covers to be designed and approved in accordance with ASME/ANSI A112.19.8. Justification for requiring each drain cover to be capable of handling the full flow of the circulation system. The current “entrapment avoidance” language does not fully address the leading cause of injury and death, hair entrapment. This hazard is caused by flowing water pulling hair into the drain cover, where it may tangle, puff up and mechanically bind if the drain’s flow rating is exceeded. The installer must select and install drain covers that are rated for the full circulation system flow, an issue not currently addressed in Sections AG106 and 3109.5. Furthermore, there is no known backup for hair entrapment because it is caused by flowing water, not by high vacuum levels. Obstruction of one outlet of a pair by debris, such as leaves, will divert full flow to the other. Justification for not requiring drains for circulation. Fully submerged suction outlets (drains) have minor influence on circulation throughout pools and spas; this required function is handled by placing returns throughout the pool in order to achieve uniform distribution of sanitizers and to avoid stagnation. The current language of Sections AG106 and 3109.5, “Suction outlets shall be designed to produce circulation throughout the pool or spa” is technically inaccurate. Recent successful installations without submerged suction outlets demonstrate the viability of the approach. The requirements of circulation/sanitization are defined elsewhere. Justification for allowing Custom Engineered or Specialized Covers: There are many swimming pool designs that do not use the traditional suction outlet fittings and may prevent entrapment when only one suction outlet and cover is used. Examples are waterparks, swim spas, floor-cleaning systems. The covers used in these designs may still be required to be tested or certified to the ANSI/ASME A112.19.8 standard, but by their design are either too large to allow body entrapment, have return water coming out of the same fitting thus pushing bathers away, or have no direct suction. Therefore, dual drains are not required in all installations to prevent body entrapment. Justification for reorganizing the code language. During the past two years aquatics industry experts, safety experts, and researchers have studied the issue of suction entrapment in swimming pools, therapy spas, hot tubs, wading pools, and other bather accessible recreational aquatic facilities. . Consensus indicates that there are five primary entrapment hazards: Body entrapment: A large portion of the body, such as back, stomach, or buttocks is held against a suction outlet, with or without cover, due to differential pressure. Limb entrapment: occurs with broken or missing cover/grates or uncovered sumps where the suction pipe is accessible to an arm or leg. Entrapment may be aggravated by swelling. Evisceration is only known to occur with an uncovered sump when the buttocks of a young child seal the outlet. Typically, this occurs in wading pools. The process can occur essentially instantaneously as the inertia of the flowing water can produce a near vacuum. Hair entrapment can occur with inappropriate outlet cover design or excessive flow. Mechanical entrapment usually involves jewelry or clothing becoming entangled in an outlet cover. It is imperative that all five hazards be addressed. The proposed language achieves this goal. Current language is technologically restrictive because it does not include all viable means. Moreover, it does not sufficiently address Evisceration, Hair or Mechanical entrapment and has limited mitigation value against Limb entrapment. The safest method is to eliminate all submerged suction outlets, using skimmers or overflow gutters to provide flow to the pump and suitable positioning of return inlets to provide proper circulation and sanitization. When submerged suction outlets are used, they must be manufactured and installed in accordance with the standards referenced herein and maintained in good working condition. The proposed language allows for a number of proven and applied methods already in use that can prevent or mitigate all of the known hazards when submerged suction outlets are used. The proposed language will also allow the contractor to use multiple entrapment avoidance options when the design or location of the project dictates. Analysis: The proponent has not submitted the referenced standards for review prior to the printing of this errata. Staff will review the standard and post the results to the ICC website prior to the code change hearings. Cost Impact: Will increase the cost of construction. - 41 - PART I - IRC Public Hearing: Committee: AS Assembly: ASF PART II - IBC Public Hearing: Committee: AS Assembly: ASF AM AMF D DF AM AMF D DF RB235-04/05: Add the following code change: RB235-04/05 AG108.1 Proponent: Carvin Digiovanni, National Spa and Pool Institute Revise as follows: ANSI/NSPI-5 992003 Standard for Residential In-ground Swimming Pools . . . . . . . . . . . . . . . .

Cost Impact: None Public Hearing: Committee: AS Assembly: ASF AM D AMF DF RB237-04/05: Add the following code change: RB237-04/05 R302.2 (New) Proponent: Roger M. Robertson, Chesterfield County, VA, representing Virginia Building and Code Officials Association Add new text as follows: R302.2 Noncombustible exterior wall covering. Exterior walls with a fire separation distance less than 5 feet shall have a noncombustible exterior wall covering consisting of one of the following: 1. brick veneer, concrete masonry veneer, stone veneer, or cement fiber siding, each complying with the minimum thickness requirements of Table R703.4; 2. steel siding complying with the minimum thickness requirements of Table R703.4 installed over a backing of concrete, masonry or 5/8-inch Type X gypsum sheathing; 3. exterior plaster complying with Section R703.6; or 4. other approved noncombustible material. Exceptions: 1. Aluminum or vinyl siding complying with the minimum thickness requirements of Table R703.4 installed over a backing of concrete, masonry or 5/8-inch Type X gypsum sheathing. 2. Combustible architectural trim not exceeding 10% of the wall area. 3. Approved fire-retardant-treated wood intended for exterior installation installed over a backing of concrete, masonry or 5/8-inch Type X gypsum sheathing. Reason: The IRC does not regulate the combustibility of exterior wall coverings for exterior walls, including those that are erected closer than 5 feet to the lot line. Section 1406.2.2 of the IBC prohibits combustible exterior wall coverings from exceeding 10% of the wall area on exterior walls with a fire separation distance of 5 feet or less. This is to prevent flames coming through openings - 43 - of a burning building on the opposite side of the property line from impinging directly on the combustible wall covering. This can occur since the IRC permits up to 25% unprotected openings in exterior walls with a fire separation distance of as little as 3 feet. In developing the opening limitations of Table 704.8 of the IBC, it was assumed that flames extending through an opening project 6 feet beyond the face of the wall. By prohibiting combustible exterior wall coverings where the fire separation distance is less than 5 feet, direct flame impingent should be avoided since there will be a minimum of 8 feet between the wall with the opening, and the wall with the combustible exterior wall covering on the opposite side of the property line. Under this proposal, combustible exterior wall coverings will still be permitted where 5 feet or more fire separation distance is provided. In addition, vinyl siding will also be permitted provided it is installed over a noncombustible backing. Cost Impact: This code change will impact the cost of construction. Public Hearing: Committee Assembly: AS ASF AM D AMF DF RB238-04/05: Add the following code change: RB238-04/05 R302.1 Proponent: Roger M. Robertson, Chesterfield County, Virginia, representing Virginia Building and Code Officials Association Revise as follows: R302.1 (Supp) Exterior walls. Exterior walls with a fire separation distance less than 5 feet (1524 mm) shall have not less than a one-hour fire-resistive rating with exposure from both sides. Projections shall not extend to a point closer than 4 feet (1220 mm) from the line used to determine the fire separation distance. Projections beyond the exterior wall shall not extend more than 12 inches (304 mm) into the areas where openings are prohibited. (Remainder of section unchanged.) Reason: This is a correction to clarify that the intent of this section is to not permit projections to extend closer than 2 feet from the line used to determine the fire separation distance but its intent is to permit projections protected on the underside, such as roof soffits, to extend to a point no closer than 2 feet from the line used to determine the separation distance. Otherwise, a projection would not be permitted within 4 feet of this line.
