The buidling is protected by an automatic sprinkler system per NFPA 13-1999, thus reducing the size 'of a potlentlal fire and its affect on the structural eloments of the building. 2. Previous Indiana Building Code (based on the 1997 UBC) did.not require floors supporting shafts to be fire rated. Previous codes over 75 years did not have this requirement. 3. Two (2) simularvariances have been approved (05-11-33 and 04-11-1). 4. Any structural collapse of the building will bring down the shafts. 5. The Carmel Building Department is aware of the condition and is not opposed to the variance.

The condition was overlooked, even by local building inspectors during a number of earlier inspections. The owner's undue hardship is the cost of demolition and reconstruction to correct the condition (over $200,000) and the delay of completion and occupancy of the buidling.

Fax 317.656.3501 To: Jim Blanchard From: Fred Simmons Copied To: Jim Ochs, Gary Hoyt Date: February 2, 2006 Re: Meridian Corporate Plaza Two Jim: Thank you and Jim Ochs for meeting with Larry Longman and me this morning to discuss Meridian Corporate Plaza Two, now under construction at 301 Pennsylvania Parkway. It is my considered professional opinion that a portion of the IBC is ambiguous, as it relates to "fire barriers" associated with vertical exits and shaft enclosure walls. Section 706.4.and 707.4 relate to the concept of "continuity" Both Sections contain the sentence "the supporting construction shall be protected to afford the required fire-resistance rating of the element protected...:" Jim Ochs has taken the position that the structural steel, supporting the floor slabs which support the "fire barriers" shall be fire proofed. I respectfully disagree with this interpretation for the following reasons: 1. The Code allows a building to be constructed as a Type II-B (un-protected), up to four stories in height, when equipped with an automatic fire suppression system. 2. The Code does not require that "fire barriers" be structurally independent as is required for "fire walls". The vertical exit enclosures for this project are constructed using metal studs and 2-layers of 5/8" type x drywall on both sides (2 hour rating), supported on concrete floor slabs, from slab to underside of deck. I believe this complies with the concept of "continuity". Granted, the elevated slabs are supported by un- protected steel. Based on Jim Ochs' interpretation, the steel supporting that portion of the slab, including columns, would be required to be fire-proofed. The vertical shaft enclosures for this project are constructed using a shaft wall assembly, running from the slab on grade to the roof deck above. They are horizontally braced to the floor slabs as they go vertical. Based on Jim Ochs' interpretation, this meets the Code. In both cases, if a catastrophic event caused the structure to collapse, both the vertical exit enclosures and vertical shaft enclosures will also collapse. Again, the code does not require "fire barriers" to be structurally independent. We would prefer to file a Variance Application with the State to resolve this matter; therefore, we respectfully request your and Gary Hoyt's support for this Variance. I believe that the "non-compliance" with the rule will not be adverse to the public health, safety or welfare based on the following: 1. The building is protected by an automatic sprinkier system, thus reducing the size of a potential fire and its affect on the structural elements of the building. 2. The Code allows a building to be constructed as a Type II-B (un-protected), up to four stories in height, when equipped with an automatic fire suppression system. 3. The Code does not require that "fire barriers" be structurally independent as is required for "fire walls". 4. If a catastrophic event caused the structure to collapse, both the vertical exit enclosures and vertical shaft enclosures will also collapse. 5. Previous Indiana Building Codes (based on the 1997 UBC) did not require floors supporting shafts and vertical exits to be fire rated. 6. Similar Variances have been approved, most recently on the North Meridian Medical Pavilion building in Carmel, IN. We would like to file this Variance as soon as possible, so that if it is denied, we will have ample time to prepare the steel to accept the fire-proofing. As mentioned in our meeting today, we will also file Variances related to the elevators. I will fax you a copy, of the Applications for your review. Again, we request a separate letter from you and Gary Hoyt associated with these issues. Thanks again for your time and consideration. Cr EL JAMES BRAINARD, MAYOR April 26, 2006 James Blanchard, Building Commissioner City of Carmel, Department of Community Services/BCE 1 Civic Square Carmei, IN 46032 Dear Mr. Blanchard; Pi ease let this letter be considered the official position of the Carmel Fire Department regarding the application for variance 06-05-43, referenced as Meridian Corporate Plaza Two, specifically dealing with the variance to Section 707.5 of the 2003 Indiana Building Code. In our departments opinion the fire resistant rating required by the code needs to be complied within the interest of public safety. The buIlding at present is in a condition that would provide access to these shafts for proper fire resistant materiais to be attached to the surfaces required by the code. As the building of multiple level buIldings seem to be flourishing in our community, we stand along side the building department in taking a stand against allowing these structures to variance away important buIlding safety requirements. Thank you for your efforts in fire safety for our community. Respectfully, 11/\ f.

Mature size is about 35' high and 25' in width of branch s'pread without pruning (so they will have to be pruned away from the building). They are purplelred leafed and some suffer from tungal diseases that might predispose them to early mortality. There seem to be six Japanese Lilac 'Ivory Silk' trees, Syringa reticulate of 3.5" caliper planted around the building as well. They will get to be 25' in height and 15' wide at maturity (15-20 years). There are four spruce trees that are 8' at planting near the ends of the buildings that can grow to 50' in height and 25' or 30' in circumference. They do not do well in ice and snow loading. There are also 4 swamp white oak trees (Quercus bicolor) 3.5" in diameter at planting around the back patio. These are very slow growing and very strong wooded. These at maturity (50-100 years) could reach 50-80' height and 35-50' in crown width and are very strong trees. Plus there are a variety of 24" shrubs next to the building and patio and walk areas. Both these buildings mirror each other, and getting around the backside with fire andlor emergency equipment would be difficult at best (because of multiple problems: uneven grade, ground wetness, woody vegetation, etc. In the front there is parking, walkways, and landscaping. My information is gathered the landscape plans submitted (and approved) for Lauth's development, and from the Handbook of Landscape Tree Cultivars by Willet Wandell, Dirr's Hardy Trees and Shrubs by Michael Dirr, and Native Trees, Shrubs, and Vines for Urban and Rural America - a Planting Design Manual for Environmental Designers, by Gary Hightshoe.

These regulations shall be known as the Building Code of [NAME OF JURISDICTION], hereinafter referred to as "this code." .:. The purpose of this section is to identify the adopted regulations by inserting the name of the adopting juris- diction into the code. 101.2 Scope. The provisions of this code shall appiy to the con- struction, alteration, movement, enlargement, replacement, re- pair, equipment, use and occupancy. location, maintenance, removal and demolition of every building or structure or any ap- purtenances connected or attached to such buildings or struc- tures. Exception: Detached one- and two-family dwellings and multiple single-family dwellings (townhouses) not more than three stories high with separate means of egress and their accessory structures shall comply with the International Residential Code. .:. This section establishes when the regulations con- tained in the code must be followed, whether all or in part. Something must happen (construction of a new building, modification to an existing one or allowing an existing building or structure to become unsafe) for the code to be applicable. While such activity may not be as significant as a new building, a fence is considered a structure and, therefore, its erection is within the scope of the code. The building code is not a maintenance document requiring periodic inspections which will, in turn, result in an enforcement action, although periodic inspections are addressed by the International Fire Code (IFC). The exception mandates that detached one- and two-family dwellings and townhouses that are not more than. three st()rie~ high .a.od. hay",. s\lparat\l means of. egress are to comply with the International Residential Code (IRC) and are not required to comply with the In- ternational Building Code (IBC). This applies to all such . structures, whether or not there are lot lines separating them and also to their accessory structures, such as ga- rages and poois. Such structures four stories or more in height are beyo'nd the scope of the IRC and must com- ply with the provisions of the IBC and its referenced codes. 101.2.1 Appendices. Provisions in the appendices shall not ap- ply unless specifically adopted. .:. The provisions contained in Appendices A through J are not considered part of the code and are therefore not enforceable unless they are specifically included in the ordinance or other adopting law or regulation of the ju- risdiction. See Section 1 of the sample ordinance on page v of the code for where the appendices to be adopted are to be specified in the adoption ordinance. 1.2 ~, ADMINISTRATION d:!II.3_ll.ltent. j he E:!!...rptl~e"llfthis-CodeTs"tt'-establish.tti=iijt- JlIlum-regutl'ffiiefltsfO:-Safeguara~e .public-heaItli, safely'- anCl> <!:enera1"welIare-rhfoyg!l,structuraLstr~.1Jgtli. means Qf.egress fii:? @itleS._stablJrtv;"'Saiiifiillon, aaeQUateliglinmd-venlilati~ ~se~ti2.h-and:s:afel~rtO:\jfe'.aml~'from-fife and",) bthei-JlllzardS.attnhlltprl.to.the-builtenvir.onrn91t. .:. The intent of the code is to set forth regulations that es- tablish the minimum acceptable level to safeguard pub- lic health, safety and welfare. The intent becomes im- portant in the application of such sections as Sections 102, 104.11 and 113, as well as any enforcement-ori- ented interpretive action or judgement. Like any code, the written text is subject to interpretation. Interpreta- tions should not be affected by economics or the poten- tial impact on any party. The only consideration should be protection of pubiic health, safety and welfare. 101.4 Referenced codes. The other codes listed in Sections 101.4.1 through 101.4.7 and referenced elsewhere in this code shall be considered part of the requirements of this code \0 the prescribed extent of each such reference. .:. The Internationai Code Council (ICC) promulgates a complete set of codes to regulate the built environment. These codes are coordinated with each other so as not to contain conflicting provisions. When the code is adopted by a jurisdiction, the codes that regulate a buiiding's electrical, fuel gas, mechanical and plumbing systems are also included in the adoption and are con- sidered a part of the code. The International Property Maintenance and International Fire Code are also refer- enced and enable the code enforcement official to ad- dress unsafe conditions in existing structures. Various other sections of the code also speciflcally refer to these codes. Note that these codes are iisted in Chapter 35 and further identified by the specific year of issue. Only that edition of the code is iegally adopted and any future editions of these codes are not enforceable. The issu- ance of new editions of all the International Codes oc- curs concurrently..and new editions of the referenced codes are adopted with each new edition of the buiiding code. Adoption is done in this manner so that there are not conflicting provisions in these codes. 101.4.1 Electrical. The provisions of the lee Electrical Code shall apply to the installation of electrical systems, including alterations, repairs, replacement, equipment, appliances, fix- tures, fittings and appurtenances thereto. .:. The ICC Electrical Code regulates all aspects of el~?tri- cal systems arid is adopted by reference in this sec1lon, as well as Section 2701.1, as the enforceable document for regulating electrical systems. Note that the ICC Elec- trical Code contains the necessary administrative provl- . sions for enforcing the requirements of NFPA 70, the' National Electrical Code. 101.4.2 Gas. The provisions of the International Fuel Gas Code. shall apply to the installation of gas piping from the po lOt .of de- livery, gas appliances and related accessories as covered in C200ll-INTERNAT10NAL-BUILDING.CODE@.COMMENt. 705.11-707.1 705.11 Ducts and air transfer openings.

Openings are not permitted in party walls constructed in accordance with Section 503.2, 2. Openings shall not be limited .to 120 square feet (11 . m') where both buildings are equipped throughout with an automatic sprinkler system installed in accor- dance with Section 903.3.!.!. -:-In order to maintain the integrity of t6e fire wall, the max- imum area and percent of openings i(l the wail are re- stricted. When provided, the openings must be properly protected so that the fire-resistance rating of the wail is maintained. This section prescribes the maximum area and the percent of openings that may be permitted in a fire wall at anyone floor level. It should be noted that the provisions must be used in concert with Section 503.2, which limits openings for party wails. Fire wail openings have restrictive limitations in their size and total area because of the critical function that a fire wall serves, To maintain the required fire perfor- mance of the fire wall, each opening through a fire wall is restricted in area to 120 square feet (11 m') and the aggregate width of all openings at anyone floor level may not constitute more than 25 percent of the length of the wail. The 120-square-foot (11 m') limitation provides a reasonable size through which industrial machinery may pass, and corresponds with the maximum area lim- itations of many tested fire doors. Recognizing the effectiveness of automatic sprin- klers, the 120-square-foot (11 m') opening limitation does not apply where the complete buildings on both sides of the fire wail are sprinklered (see Exception 2). However, the aggregate width of ail openings in a fire wall at anyone fioor level is still limited to 25 percent of the length of the wall. 705.9 Penetrations.

Joints made in or between fire walls shall comply with Section 712. -:- Joints, such as expansion or seismic, are another form of opening in fire wails and, therefore, must be consid- ered with regard to maintaining the fire-resistance rat- ings of fire walls. This section requires all joints that are located in fire walls to be protected by a joint system with a fire-resistance rating and comply with the require- ments of Section 712. 2000 INTERNATIONAL BUILDING CODE@COMMENTARY 705,8 - 706.1 705.11 Ducts and air transfer openings. Ducts and air transfer openings shall not penetrate fire walls.

SECTION 706 FIRE BARRIERS 706.1 General. Fire barriers used for separation of vertical exit enclosures, exit passageways, horizontal exits or incidental use areas, to separate different occupancies or to separate a single occupancy into different fire areas, shall comply with this sec- tion, -:- The provisions of this section apply to assemblies that are required to have a fire-resistance rating and are used for separating exits, incidental use areas and fire areas. Fire barriers provide a higher degree of protec- tion than fire partitions (see Section 708). The amount of openings is limited in fire barriers, and fire barrier wall assemblies must be continuous from the top of a fire-re- sistance-rated floor/ceiling assembly below to the floor or roof slab/deck above. Unlike fire partitions, there are no circumstances under which a fire barrier wall is per- mitted to terminate at a ceiling. Fire barriers are used for a variety of purposes, such as mixed occupancies and area of refuge separations and shaft, and exit and fioor opening enclosures. Fire barriers also inciude interior walls which serve to subdivide a space by separating one fire area from an adjacent fire area and for separat- ing incidental use areas (see Section 302.1.1.1). Fire- resistance-rated assemblies used to separate exit ac- cess corridors as well as tenant, dwelling unit and guestroom separations are fire partitions (see Section 708). The provisions of this section provide minimum re- quirements for the fire-resistance rating, continuity, combustibility and protection of openings and penetra- tions in order to help maintain the reliability of the fire separation assembly. As with any fire-resistance-rated assembly, consideration must be given to the openings and penetrations that are provided within the assembly. The intent, in part, is to maintain the fire-resistance rat- ing of the assembly. These sections recognize that fire spread beyond a fire-resistance-rated compartment is often attributed to the protection given any opening or penetration of the fire barrier, or the lack thereof. ~11~~~;;,~rr~1J2~ended:Jo;pT:QVidecarrelra~ r;;.sub'dW~ 'ar~lI.lek;odSl~lor.wm:uCtE?trut:1Qf;;il!YlI @!p.pUtts;the'assmnb1\1lis;re-qoired.lo,prqy!.8!tllt;teast.th~ (l5dlll",l:ii5imy;rrt[e,",esISlalE.ml'ilrtlg~;;S:tJje:wte...JJ.<!rri~ 7-35 706.2 - 706.4 This is applicable regardless of the type of construction of the building. Structural stability is regulated by Sec- tion 708.4. 706.2 Materials. The walls and floor assemblies shall be of ma- terials permitted by the building type of construction. .:. The types of materials used in fire barriers are to be consistent with Sections 602 through 602.5 for the type of construction classification of the building. It should be noted that the fire-resistance ratings of fire barriers used to separate mixed occupancies are determined in ac- cordance with Section 302.3 (see commentary, Section 302.3). Fire barriers are permitted to be of combustible materials in Type III, IV and V construction and are re- quired to be of noncombustible materials in Type I and II construction. 706.3 Fire-resistance rating. The fire-resistance rating of the walls and floor assemblies shall comply with this section. .:. This section identifies the types of assemblies, both ver- tical and horizontal (see also Section 710.3), which are required to be fire-resistance rated and constructed as fire barriers. 706.3.1 Vertical exit enclosure. The fire-resistance rating of the separation between building areas and a vertical exit enclosure shall comply with Section 1005.3.2. .:. See Section 1005.3.2, which requires vertical exit en- closures to be constructed of fire barriers. 706.3.2 Exit passageway. The fire-resistance rating of the sepa- ration between building areas and an exit passageway shall com- ply with Section 1005.3.3. .:. See Section 1005.3.3.2 which requires exit passage- ways (as defined in Section 1002) to be constructed of fire barriers. 706.3.3 Horizontal exit. The fire-.resistance rating of the sepa- ration between building areas connected by a horizontal exit shall comply with Section 1005.3.5. .:. See Section 1005.3.5.1, which requires horizontal exits (as defined in' Section 1002) to be constructed of fire barriers. 706.3.4 Incidental use areas. The fire barrier separating inci- dental use areas shall have a fire-resistance rating of not less than that indicated in Table 302.1.1. .:. Table 302.1.1 requires either an automatic fire suppres- sion system or fire barrier, or both, in order to protect in- cidental use areas. Section 302.1.1.1 further requires nonfire-resistance-rated construction which is capable of resisting the passage of smoke where only a fire sup- pression system, not a rated separation, is required. 706.3.5 Separation of occupancies. The fire barrier separating mixed occupancies, or a single occupancy into different fire ar- eas, shall have a fire-resistance rating of not less than that indi- 7.36 FIRE.RESISTANCE.RATED CONSTRUCTION cated in Section 302.3.3 based on the occupancies being separated. .:. One of the alternatives available in addressing fire pro- tection systems in many buildings is to divide the build- ing into separate fire areas. This is true for determining separated occupancies (see Section 302.3.3) and many of the fire suppression system thresholds (see Section 903.2). If the separation is provided, each.fire area may be evaluated separately for purposes of de- termining the applicable provisions. Areas separated with fire barriers are not considered separate buildings; they are considered separate fire areas. Two areas must be separated by a fire wall or ex- terior walls to be considered separate buildings. Two ar- eas separated with fire barriers are still considered as part of a single building. This distinction is critical in de- termining compliance with allowable height and \area and other code provisions. 706.4 Continuity. Fire barriers shall extend from the top of the floor/ceiling assembly below to the underside of the floor or roof slab or deck above and shall be securely attached thereto. These walls shall be continuous through concealed spaces such as the space above a suspended ceiling. The supporting con- struction shall be protected to afford the required fire-resistance rating of the fire barrier supported except for l-hour fire-resis- tance-rated incidental use area separations as required by Table 302.1.1 in buildings of Types lIB. IIIB and VB construction. Hollow vertical spaces within the fire barrier wall shall be firestopped at every floor level. Exceptions: 1. The maximum required fire-resistance rating for as- semblies supporting fire barriers separating tank stor- age as provided for in Section 415.7.2.1 shall be 2 hours, but not less than required by Table 60 I for the building construction type. 2. Shaft enclosure shall be permitted to terminate at a top enclosure complying with Section 707.12. .:. To minimize the potential for fire spread from the ex- posed side of a vertical fire barrier (wall) to the unex- posed side, such assemblies must be continuous from a fire-resistance-rated floor/ceiling assembly below to the underside of the floor slab or roof deck above (see Fig- ure 706.4 ).To maintain the efficiency of the fire barrier, it must be continuous through all concealed spaces (such as a space' above a suspended ceiling) and be con- structed tight and securely attached to the underside of the floor or roof slab or deck. Fire barriers must be supported by construction hav- ing an equivalent fire-resistance rating. The intent of this requirement is to prevent the effectiveness of the as- sembly from being circumv.\l~}~8'By,,~t~\7!\=le.~!b.r~atens the supporting elements. "IW&r~ff.emefWfor'5tr.uctu(a~ WRo!:ttappl1"<'tn'~IU~pas4lf:toosttuction;A . All hollow vertical spaces in the fire separation walls must be fireblocked at the ceiling and floor or roof levels in accordance with Section 716.2.2. This continuity cri- terion is what distinguishes fire barriers from fire parti- tions (see commentary, Section 708.4). 2000 INTERNATIONAL BUILDING CODEiIl> COMMENTARY 'FIRE:RESISTANCE-RATED CONSTRUCTION Fire barriers are required by Section 302,1,1,1 for in- cidental use areas, The incidental use area provisions compartmentalize areas of the building with increased risks, thereby providing protection for other areas of the building with comparatively lower risk, By requiring these incidental use fire barriers to be supported by construction with equivalent fire resistance, the code would philosophically be protecting the increased risk area from fire in the low risk portion of the building, This would be particularly onerous, for example, in buildings with unprotected types of construction with areas in business buildings of Type liB, IIIB or VB construction, The location of an incidental use storage area would ef- fectively change the required type of construction in a portion of the building, This exception maintains the fire-rated separation without triggering the type of construction problems in unrated buildings, The philosophy is similar to that rec- ognized for tenant, guestroom and exit corridor separa- tions in Section 708.4 and smoke barriers in Section 709.4. 706.:; Exterior walls. Where exterior walls serve as a part of a required fire-resistance-rated enclosure, such walls shall com- ply with the requirements of Section 704 for exterior walls and the fire-resistance-rated enclosure requirements shall not apply. Exception: Exterior walls required to be fire-resistance rated in accordance with Section 1005,3,65, .:. If an area is required to be enclosed by fire barriers and an exterior wall constitutes part of the enclosure, the ex- terior wall is only required to comply with the fire-resis- tance rating requirements in Section 704, unless the area enclosed is part of an exit stairway (see commen- tary, Section 1005,3,6,5), The intent of the fire barrier re- quirements is to subdivide or enclose areas to protect them from a fire in the building, The exterior wall need only have a fire-resistance rating if required for struc- tural stability (see Table 601) or because of exterior ex- posure potential (see Table 602 and Sections 704,5 and 1005,3,6,5), FIRE-RESiSTANCE.RATED FLOORlCE1LlNG ASSEMBLY NONFIRE-RESISTANCE- RATED FLOORJCEILlNG A5SEMBL Y 706,5 - 706,6 'I 'I I I I 706.6 Openings. Openings in a fire barrier wall shall be pro- tected in accordance with Section 714, Openings shall be lim- ited to a maximum aggregate width of25 percent of the length of the wall, and the maximum area of any single opening shall not exceed 120 square feet (11 m'). Openings in exit enclosures shall also comply with Section 1005.3.4. Exceptions: 1. Openings shall not be limited to 120 square feet (11 m') where adjoining fire areas are equipped throughout with an automatic sprinkler system in accordance with Section 903.3.1.1. 2. Fire doors serving an eXIt enclosure. 3. Openings shall not be limited to 120 square feet (11 m') or an aggregate width of 25 percent of the length of the wall where the opening protective assembly has been tested in accordance with ASTM E 119 and has a minimum fire-resistance rating not less than the ,fire- resistance ratiflg,o(the 'iV~Il.. _ ' .:. To maintain the viability of the fire barrier, the aggregate width of openings is restricted to a maximum of 25'per- cent of the length of the wall. This limitation is based on the fact that the criteria for opening protectives do not in- clude limitations on unexposed surface temperature or radiant heat transfer. Consistent with typical listing limi- tations, a single opening protective is limited to a maxi- mum of 120 square feet (11 m'). It should be noted, however, that certain opening protectives, such as fire windows, are often limited to much smaller areas per opening. The reference to Section 1005.3.4 specifies that in exit enclosures, only openings for the purpose of egressing from normally occupied spaces are permit- ted. Spaces that are not normaily occupied, such as jan- itor closets or mechanicai and electrical rooms, are not permitted to open directly into the exit enclosure. Unoc- cupied spaces are not permitted to open directly into the exit enclosure, since fire in those areas may go unde- tected for a long period of time and, therefore, these ar- eas pose a greater fire hazard than occupied spaces.

A fire door assembly includes all required hardware, anchor- age, frames and sills necessary to provide an accept- able opening protective. The reference to Section 714 is intended to identify the required fire protection rating for the opening protective, as indicated in Tabie 714.2, as well as the applicable test standards. Openings in fire barriers are not limited in size when all fire areas separated by that assembly are equipped throughout with an automatic sprinkler system (see Ex- ception 1). This exception is similar to one made for fire walls (see Section 705.8), based on the effectiveness of automatic sprinkler systems. Although the openings in the fire barrier are not iimited in size under this excep- tion, they are still required to be protected by opening protectives that meet the requirements of Section 714. Exception 2 acknowledges the practicality of the 25- percent limitation for walls of an exit enclosure. Most exit enclosures are of such limited size that the place- ment of the fire door in the wall of the enclosure exceeds 25 percent of the wall. Exception 3 addresses new opening protective prod- ucts which have been tested to the more rigorous provi- sions of ASTM E 119 rather than, or in addition to, the opening protective standard NFPA 252. Since the open- ing protective has been tested to the same standard as the wall itself, it is then logical to allow such opening pro- . tective without restrictions.

Penetrations through fire barriers shall comply with Section 711. .:.In order to maintain the integrity of the fire barrier, pene- trations into and through it must be properly protected. Acceptable protection methods for various penetrations of fire barriers are identified in Sections 711.3 through 711.3.4, while methods for protection of penetrations of fire-resistance-rated floor/ceiling and roof/ceiling as- semblies are identified in Sections 711.4 through 711.4.6. .' . . d' 706.7.1 Prohibited-penetrations. Penetrations into an exit en- closure shall only be allowed when permitted by Section 1005.3.4.1. .:. See Section 1005.3.4.1. 706.8 Joints. Joints made in or between fire barriers shall Com- ply with Section 712. .:. This section regulates joints or linear openings created between building assemblies, which are sometimes re- ferred to as construction, expansion or seismic joints. These joints are most often created where the structural design of a building necessitates a separation between building components, in order to accommodate antici- pated structural displacements caused by thermal ex- pansion and contraction, seismic activity, wind or other 7-38 FIRE.RESIST ANCE.RA TED CONSTRUCTION loads. Figure 712.1 iilustrates some of the most com- mon locations of these joints, These linear openings create a "weak link" in fire-re- sistance-rated assemblies which can compromise the integrity of the tested assembly by allowing an avenue for the passage of fire and the products of combustion through the assembly. In order to maintain the efficacy of the fire-resistance-rated assembly, these openings must be protected by a joint system with a fire-resis- tance rating equal to the adjacent assembly. .It is not the intent of this section to regulate joints instailed in as- semblies that are provided to control shrinkage crack- ing, such as a saw-cut control joint in concrete (see Sec- tion 712). 706.9 Ducts and air transfer openings. Penetrations by ducts and air transfer openings shall comply with Sections 71 I and 715. .:. See Sections 711 and 715. SECTION 707 SHAFT ENCLOSURES 707.1 General. The provisions of this section shall apply to ver- tical shafts where such shafts are required to protect openings and penetrations through floor/ceiling and roof/ceiling assem~ blies. .:. This section applies to all vertical shafts, including those covered by other sections of the code, namely: interior stairways (see Section 1005.3.2); refuse waste- and linen-handling chutes (see Section 707.13); and eleva- tor and dumbwaiter hoistways (see Section 707.14). All openings or penetrations in floor/ceiling or roof/ceiling assemblies are required to be protected with a verticai shaft enclosure, unless one of the excep- tions provided for in Section 707.2 is applicable. The key consideration is one of determining whether or not a shaft isrequired. The requirements for shaft en- closures are found in Section 707.2. 707.2 Shaft enclosure reqnired. Openings through a floor/ceil- ing assembly shalJ be protected by a shaft enclosure complying with this section. Exceptio~s: 1. A shaft enclosure is not required for openings totalJy within an individual residential dwelJing unit and con. necti!lg four stories or less. 2.

To maintain the required fire performance of the fire waU, each opening through a fire wall is restricted in area to 120 square feet and the aggregate width of all openings at anyone floor level may not constitute more than 25 percent of the length of the wall. The 120-square-foot limitation provides a reasonable size through which industrial machinery may pass, and corresponds with the maximum area limitations of many tested fire doors. Recognizing the effectiveness of automatic sprinklers, the l20-square-foot opening limitation does not apply where the complete buildings on both sides of the fire wall are sprinklered.

These openings accommodate the functional need in the first floor of many buildings, such as for the passage of large vehicles or equipment. Accordingly, openings in a fire wall at the first floor level may be increased to 240 square feet in area provided that the first story on each side of the fire wall is protected with an approved automatic sprinkler system and there is at least 3 feet between adjoining openings.

The provisions of this section apply to assemblies tbat are required to have a fireresistance rating and are used for separating fire areas. Fire separation assemblies provide a higher degree of protection than fire partitions (see Section 711.0). The amount of openings is limited in fire separation assemblies, and fire separation wall assemblies must-be continuous from the top of a fireresistance rated floor/ceiling assembly below to the floor or roof slab/deck above. Unlike fire partitions, there are no circum- stances under which a fire separation wall is permitted to termi- nate at a ceilingt Fire separation assemblies are used for a variety ,,-of purposes, such as mixed use group and area of refuge separa- .Jions and shatt, an~x1i-ana-fIOor opening enclosures. Fire separatlOn-as-semtrttes-woutd also imJudc i8tGriol w ulls which serve to subdivide a space by separating one fire area from an adjacent fire area. Fireresistance rated assemblies used to sepa- rate exit access corridors as well as tenant, dwellin unit an ID!~troom separatIons are Ire oartltions (see ection 711.0). "Table 602 can 'be used to -further determine where fire separation assemblies and fire partitions are required. The integrity of fire separation assemblies is ~onsidered in the provisions of Sections 709.1, 709.3, 709.4, 709.6 and 709.7 through 709.7.2. These sections provide minimum requirements for the continuity, combustibility and protection of openings and penetrations in order to belp maintain the reliability of the fire separation assembly. As with any fireresistance rated assembly, consideration must be given to the openings and penetrations that are provided within the assembly. The intent, in part, is to maintain the fireresistance rating of the assembly. These sections recognize that fire spread beyond a fireresistance rated compart- ment is often attributed to the protection given any opening or penetration of the fire separation assembly, or the lack thereof. Since the fire separation assembly is intended to provide a reliable subdivision of areas, the construction which structurally supports the assembly is required to provide at least the sarne hourly flferesistance rating as the fire separation assembly. This is applicable regardless of the type of construction of the build- ing. Structural stability is regulated by Section 709.4. . The provisions of Section 709.0 apply to.l1fire separation assemblies that are required by other sections of the code. The fireresistance rating and the types of materials used in fIre sepa- ration assemblies are to be consistent with Table 602 and Sec- tions 601.0 through 606.0 for the type of construction -classifiCation ofthe'''bliilding: It'should be' noted tliitt the fire- - resistance ratings of fire separation assemblies used to separate mixed use groups are determined in accordance with Section 313.1.2 (see conrrnentary, Section 313.0). Fire separation assem- blies are generally permitted to be of combustible materials in Types 3,4 and 5 construction and are required to be of noncom- bustible materials in Types 1 and 2 construction. In accordance with Table 602, specifically approved fireretardant-treated wood - is pennitted to be used in certain fire separation assemblies, depending on use, and limited to assemblies having a fire- resistance rating of 1 hour or less. . One of the alternatives available in addressing fire protection systems in many buildings is to divide the building into separate fire areas, TIlls is true for detennining separated use groups (see Section 313. 1.2) and many of the fire suppression system thresh- olds. If the separation is provided, each fire area may be evaluated separately for purposes of detennining the applicable provisions. Areas separated with fire separation assemblies are not con- sidered separate buildings. They are considered separate fire areas. Two areas must be separated by a fire wall or exterior walls to be considered separate buildings. Two areas separated with fire separation asse-mblies are still considered as part of a single building, This distinction is critical in determining compliance with allowable height and area and other code provisions, FIRERESISTANT MATERIALS AND CONSTRUCTION . To maintain the viahility of the fire separation assembly, the aggregate width of openings is restricted to a maximum of 25 percent of the length of the wall. This limitation is based on the fact that the criteria for opening protectives do not include limitations on unexposed surface temperature or radiant heat transfer. Consistent with typical listing limitations, a single open- ing protective is limited to a maximum of 120 square feet. It should be noted, however, that certain opening protectives, such as fire windows, are often limited to much smaller areas per opening. This section also specifies that in exit enclosures, only open- ings for the purpose of egressing from normally occupied spaces are pennitted. Spaces that are not normally occupied, such as janitor closets or mechanical and electrical rooms, are not per- mitted to open directly into the exit enclosure. Unoccupied spaces are not permitted to open directly into the exit enclosure __since,fire.in those, areas may..go.undetectedfor,.a long peri9d,of time a'nd, therefore, 'these areas pose -a greater fire hazard' than occupied spaces. Openings in fire separation assemblies are not limited in: size when all fife areas separated by that assembly are equipped throughout with an automatic sprinkler system. This exception is similar to one made for fire walls, based on the effectiveness of automatic sprinkler systems. Although the openings in the fire separation assembly are not limited in size under this exception, they are still required to be protected by opening protective, that meet the requirements of Section 709.3.1. . In order to maintain the required frreresistance rating of the assembly, opening protectives must have a fire protection rating in accordance with Sections 704.0 and 717.0. The reference to Section 704.0 primarily refers to Section 704.3, which defines opening protectives and clarifies that when the code refers to an opening protective, the reference is to an entire assembly. For example, a fire door assembly includes all required hard'Yare, anchorage, frames and sills necessary to provide an acceptable opening protective. The reference to Section 717.0 is intended to identify the required fire protection rating for the opening pro- tective, as indicated in Table 717.1. . To minimize the potential for fire spread from the exposed side of a vertical fire separation assembly (wall) to the unexposed side, such assemblies must be continuous from a fireresistance 7-39 THE BOCA NATIONAL BUILOING COOEI1996 COMMENTARY , L . In order to determine the anticipated protection provided by a given assembly, the hourly fireresistance rating must be deter- ntined by testing the joint system in accordance with ASTM E1l9 (see commentary, Section 704.1.1). Because of the unique nature of joints in fireresistance rated assemblies and the lack of specific criteria in ASTM E1l9 fonest specimen preparation, placement, configuration and size and for testing conditions of joint systems, this section contains seven additional criteria that are applicable to the fire testing. ' ASTM EI19 does not contain details for joint placement and configuration, such as maximum joint width, lengtb of joint, testing and location of joint splices. Item I requires that joint systems be installed for thefulllength or height of the test assembly, due to the fact that tbe openings to be protected by these types of joints are most often continuous. Items 2 and 3 set the requirements for the minimum positive pressure differential to be used for the test. The criteria stated is consistent with the requirements contained elsewhere in Chapter 7 for testing of other opening protectives. The positive pressure differential is intended to assist in evaluating whether or not the joint will remain in place during a fire condition. Item 4 is necessary since initial fIre_ testing revealed that the presence and orientation of a splice in a joint system can affect the fire performance of the joint. Many joini systems will contain a splice somewhere along the length of the system. These splices . may occur where the length of the joint to be protected exceeds the length of a prefabricated joint or where a cold joint occurs in a field-installed system. Item 5 is intended to determine that the joint system, when in a fully expanded or extended condition, will maintain the re- quired fireresistance rating. Item 6 addresses the test requirements for joints that are designed to transfer structural building loads. This is consistent with the requirements for the testing ofloadbearing fIreresistance rated assemblies. Item 7 specifically addresses test requirements for joints that are }ntended to accommodate building movement, such as ex- paiisi'on'; seismic'"an<:f\virid..sw"ily joints: The '"tequiremenCfor" preconditioning cycling is intended to allow for evaluation of the joint's ability to withstand cyclical movement over its anticipated life. i I I: ; , j" ! . The 500-cycle criteria for expansion/contraction and wind sway joints recognizes that these joints will be subjected to a greater number of movement cycles over their anticipated life due to expansion and contraction, The 100-cycle criteria for seismic joints recognizes that the anticipated number of move- ment cycles the joint will be subjected to will not be as great due to the reduced number of cycles caused by seismic activity. 7-42 . Test data has indicated that the orientation of asymmetrical joints can have an effect on the performance of the joint. As a result, all asymmetrical joint systems must be tested for fire exposure from both sides so that the required protection ~ill be provided regardless of which side of the joint is exposedito fire. The exception for joints in exterior walls correlates with the exception stated in Section 705.2 for fire exposure raiing of exterior walls. I ~lm:Ul1i1rdW~...$~ . Vertical shafts, which are an essential element of maAy mul- tistory building designs, include elevator shafts, stairways, laun- dry chutes, plumbing shafts and air shafts. An alternative to constructing a vertical shaft is to seal all openings and penetra- tions at each floor level as required in Sections 713.3 and 713.4. Vertical openings that are not properly protected can act as a chimney for smoke, hot gases and products of' combustion. Unprotected floor openings have been a major contributing factor in many large loss-of-life fires. The intent of this section is to minimize the fIre and'smoke spread caused by vertical openings by requiring a proper enclo- sure, The requirement for a shaft and the provisions for protecting penetrations and other floor openings without a shaft ericlosure are contained in Section 713,0. ' The provisions of this section are also intended to minimize the potential for a fire to spread into a shaft. In addition to the provisions of this section, other sections have prescriptive re- quirements that address specific types of shafts. For example, Section 1014.0 addresses stairways, Section 2807.0 addresses waste- and linen-handling chutes and Section 3007.0 addresses elevators and dumbwaiter hoistways. As required by Sections 710.2 and 710.3, the construction of the' shaft must.be in. accordance with the type,of construbion of the building. Therefore, Table 602 (Line 3) will regulate the fireresistance rating and the type of materials applicable to shaft construction. It should be noted, however, that shafts connecting not more than three stories need only have a fireresistance rating of I hour, regardless of the type of construction (see Note b of Table 602). Sections 710.4 and 710.5 deal with maintaining the {ntegrity of the shaft by requiring top and bottom enclosures. A~ditional requirements for the fire separation assemblies that form the shaft, such as properly protected openings and penetrations into the shafts, are given in Section 709.0. . This section applies to all vertical shafts, including those covered by other sections of the code, namely: interior stairways (see Section 10]4.0); refuse waste- and linen-handling chutes 703 -703.1 FIRE RESISTANCE.

When the fire-resistance rating determined in accordance with this exception exceeds the fire-resistance rating determined in accordance with ASTM E 119, the fife exposure time period, water pres- sure, and application duration criteria for the hose stream test ofASTM E 119 shall be based upon the fire-resistance rating determined in accordance with this exception. 703.2.1 Nonsymmetrical wall construction. Interior walls and partitions of nonsynrrnetrical construction shall be tested with both faces exposed to the furnace, and the assigned frre-resistance rating shall be the shortest dura- tion obtained from the two tests conducted in compliance with ASTM E 119. When evidence is furnished to show that the wall was tested with the least fire-resistant side exposed to the furnace, subject to acceptance of the build- ing official, the wall need not be subjected to tests from the opposite side. See Section 704.5 for exterior walls. 703.2.2 Combustible components. Combustible aggre. gates are permitted in gypsum and portland cement con. crete mixtures approved for frre-resistance-rated construc- tion. Any approved component material or admixture is permitted in assemblies if the resulting tested assembly meets the fire-resistance test requirements of this code. 703.2.3 Restrained classification. Fire-resistance-rated assemblies tested under ASTM E 119 shall not be consid. ered to be restrained unless evidence satisfactory to the building official is fumished by the registered design pro- fessional showing that the construction qualifies for a restrained classification in accordance with ASTM E 119.

You described two situations at shaft penetrations. My responses are as follows: Where a fire-resistance rated stair enclosure bears on surrounding construction, such construction must be equally protected. This could include floor assemblies, girders, beams, columns and load bearing walls. The load path is to be protected to the foundation. The protection shall extend horizontally in each direction to the next vertical load bearing element. For instance: in a steel frame building, only the structural elements of the structural bay in which the stair enclosure is located need be protected. Where a shaft (mechanical, stair, elevator, etc.) is fully self supporting through a building, the surrounding construction need not be protected since it is not supporting the shaft. It is acceptable to brace the shaft to surrounding construction without invoking protection of same. In buildings required to be protected by type of construction, the most restrictive requirement would apply. We are pleased to provide you with the opinions stated herein. Opinions of the ICC technical staff are advisory only, and as such, it is your choice as to how you use these opinions.

The Code does not require that "fire barriers" be structurally independent as is required for "fire walls". The vertical exit enclosures for this project are constructed using metal studs and 2-layers of 5/8" type x drywall on both sides (2 hour rating), supported on concrete floor slabs, from slab to underside of deck.

City of Carmel Department of Community Services One Civic Square Carmel, IN 46032 RE: Sections 714.1and 714.2 of the 2003 International Building Code Dear Me. Ochs: This letter is in response to vour question concerning the protection of structural elements that support fire-resistance rated construction Based on your letter of February 14, 2006 and its attachment, your question, as I understand it, is: Given a fully suppressed, 4-story office building of Type liB construction, what portion, if any, of adjacent construction is reqUired to be fire- resistance rated in the following two instances? Condition 1: The 2-hour vertical exit enclosures in this building are constructed of metal studs and gypsum board. In each story the stair enclosure walls (fire barriers) are supported on the floor slab. I'<esponse Structure that directly supports fire barrier walls must be protected to the same degree as the fire barriers supported In a steel frame building, the protection need not extend beyond the structural bay containing the fire barrier stair enclosure, shaft, etc Protection shall include beams, girder;, columns and the floor deck within Ihe structural bay containing the protected elements. This requirement applies regardless of construction type or sprinkler suppression. Condition 2: Other 2-hour shaft enclosures in this building use a gypsum shaft wail assembly that is continuous from the slab on grade to the roof deck. The shafts are not supported on intermediate floors but they are laterally braced to the adjacent construction. Response In this case, the entire gravity load of each shaft bears only on the grade slab Neither the surrounding construction nor the lateral bracing elements need protection. The gypsum assembly must not exceed the unsupported height limilation specified by the gypsum manufacturer. We are pleased to provide you with the opinions stated herein. They are based solely on information that you have provided. We have made no independent effort to verify the accuracy of this information nor have we conducted a review beyond the scope of your question.

Fax 317.656.3501 To: Jim Blanchard From: Fred Simmons Copied To: Jim Ochs, Gary Hoy1 Date: February 2, 2006 Re: Meridian Corporate Plaza Two Jim: Thank you and Jim Ochs for meeting with Larry Longman and me this morning to discuss Meridian Corporate Plaza Two, now under construction at 301 Pennsylvania Parkway. It is my considered professional opinion that a portion of the IBC is ambiguous, as it relates to "fire barriers" associated with vertical exits and shaft enclosure walls. Section 706.4 and 707.4 relate to the concept of "continuity" Both Sections contain the sentence "the supporting construction shall be protected to afford the required fire-resistance rating of the element protected.... " Jim Ochs has taken the position that the structural steel, supporting the floor slabs which support the "fire barriers" shall be fire proofed. I respectfully disagree with this interpretation for the following reasons: 1. The Code allows a building to be constructed as a Type II-B (un-protected), up to four stories in height, when equipped with an automatic fire suppression system. 2. The Code does not require that "fire barriers" be structurally independent as is required for "fire walls". The vertical exit enclosures for this project are constructed using metal studs and 2-layers of 5/8" type x drywall on both sides (2 hour rating), supported on concrete floor slabs, from slab to underside of deck. I believe this compiies with the concept of "continuity". Granted, the elevated slabs are supported by un- protected steel. Based on Jim Ochs' interpretation, the steel supporting that portion of the slab, including columns, would be required to be fire-proofed. The vertical shaft enclosures for this project are constructed using a shaft wall assembiy, running from the slab on grade to the roof deck above. They are horizontally braced to the floor slabs as they go vertical. Based on Jim Ochs' interpretation, this meets the Code. .... .~ -" .. In both cases, if a catastrophic event caused the structure to collapse, both the vertical exit enclosures and vertical shaft enclosures will also collapse. Again, the code does not require "fire barriers" to be structurally independent. We would prefer to file a Variance Application with the State to resolve this matter; therefore, we respectfully request your and Gary Hoyt's support for this Variance. I believe that the "non-compliance" with the rule will not be adverse to the public health, safety or welfare based on the following: 1. The building is protected by an automatic sprinkler system, thus reducing the size of a potential fire and its affect on the structural elements of the building. 2. The Code aiiows a building to be constructed as a Type II-B (un-protected), up to four stories in height, when equipped with an automatic fire suppression system. 3. The Code does not require that "fire barriers" be structurally independent as is required for "fire walls". 4. If a catastrophic event caused the structure to collapse, both the vertical exit enclosures and vertical shaft enclosures will also collapse. 5. Previous Indiana Building Codes (based on the 1997 UBC) did not require floors supporting shafts and vertical exits to be fire rated. 6. Similar Variances have been approved, most recently on the North Meridian Medical Pavilion building in Carmel, IN. We would like to file this Variance as soon as possible, so that if it is denied, we will have ample time to prepare the steel to accept the fire-proofing. As mentioned in our meeting today, we will also file Variances related to the elevators. I will fax you a copy of the Applications for your review. Again, we request a separate letter from you and Gary Hoy1 associated with these issues. Thanks again for your time and consideration.
