Modified February 19, 2007 January 5,2007 ADMINISTRATIVE MODIFICATION REQUEST RITZ CARLTON Vail, Colorado Condominium Egress and Cominon Path of Travel Introduction: As discussed in our conference call on Februarv 12,2007 the main purpose of this Administrative Modification Request is to document the request for consideration for the use of the 2006 International Building Code related to common path of travel. As you know the Ritz Carlton Project is designed with an automatic sprinkler�rotection in accordance with NFPA 13 and Fire Alarm/Detection Svstem in accordance with NFPA 72. Additionallv a smoke manaQement svstem is being provided as required for a desi�nated stair and elevator hoist-wav enclosures for fire department access to the buildinQ. Code Requirement: The Common Path of Egress Travel is defined as"that portion of exit access which the occupants are required to traverse before two separate and distinct paths of egress travel to rivo exits are available. Paths that merge are common paths of travel. Common paths of egress travel shall be included within the permitted travel distance"(Section 1002.1,2003 IBC).The common path of egress travel for that portion of exit access from anywhere in a condominium (R occupancy)is limited to 75 feet(Section 1013.3, 2003 IBC). There are approximately 6 residential units that exceed the 75 feet common path of travel.These distances have been measured from the most remote location(balcony)by the parallel wall measuring method. There is no condition that exceeds 125 feet in most cases the common path of travel is in the range of 100 feet._ C:�Documents and Settings\SCR\Desktop\Ritz Admin Mod Common Path of Travel Mod 2.19.07.doc 5420 Ward Road,Suite 200,Arvada,Colorado 80002-1838•Telephone: 303-422-7400•Fax: 303-422-7900 _ _ -- __ � , , � ____-- �. . .. __� Mike McGee-Ritz Admin Mod Common Path of Travel Mod 2 19 07 doc Page 2 � =� Code Intent: The common path of egress travel is a concept used to define travel distance criteria. Common path of travel is the course an occupant will travel and,regardless of which route is chosen,he or she must pass through the same location. The length of common path of egress travel is limited so that the route to a remote means of egress begins to diverge before the occupant has traveled an excessive distance.This reduces the possibility that,although the exits are remote from one another,a single fire condition will render both paths unavailable. The common path of travel is the distance measured from the most remote point in a space to the point in an exit path where the occupant has access to two required exits in separate directions. From a condominium (R occupancy)this distance is limited to 75 feet in the 2003 IBC and 125 feet in the 2006 IBC. Request: Clarification was provided by the Colorado Inspection Agency and Town of Vail Building Department that the balcony areas are excluded from the gross floor area in determination of occupant load for a condominium. (Confirmed by Matt Royer 2.13.2007 voice message)However,balconies have been included in determining the most remote point to measure the common path of travel distance from in a condominium. This request provides a level of protection and life safety that meets the intent required by Code. The requested condominium egress features, as described, establish an acceptable level of condominium egress within the intent of code. The request is a result of previous meetings and discussions with the Chief Building Official,Fire Marshal as well as Colorado Inspection Agency. We respectfully request the use of the section referenced below for the Ritz Carlton Project only and it is not the intent of this request to set precedence for other projects in the Town of Vail. 2006 edition of the International Building Code-Exception#4 of Section 1014.3 Common Path of Egress Travel: This exception permits the Common Path of Travel in a R-2 Residential Occupancy to be no more than 125 feet provided the building is protected throu�hout with an approved automatic sprinkler s�tem Our research of the IBC Commentarv and code action on the permitted increase in common path of travel to 125 in a R-2 Residential Occupancv in the 2006 IBC is supported bv the low occupant load and the protection provided bYan automatic C:�Documents and Settings\SCR�DesktopUtitz Admin Mod Common Path of Travel Mod 2.19.07.doc 5420 Ward Road,Suite 200,Arvada,Colorado 80002-1838.Telephone: 303-422-7400•Fax: 303-422-7900 ___ .�...�_ ....._ .�__.___ � ._..__. __ _ __� , -_ Mike McGee- Ritz Admin Mod Common Path of Travei Mod 2.19.07.doc , Page 3`, sprinkler system in accordance with IBC Section 903.3.1.1 and NFPA 13 BCER En�ineering could not find any other special conditions that would be required to permit the increased common path of travel in this buildinQ.
