1 We Bring Buildings to Life Centennial Hills Skilled Nursing Facility Fire Protection Report July 13, 2016 Revised September 15, 2016 JBA Project No At the request of Yihong Liu + Associates, Ltd., JBA Consulting Engineers prepared the following Fire Protection Report (FPR) for the new Centennial Hills skilled nursing facility. INTRODUCTION Ochoa Development proposes to construct a new skilled nursing facility located on the southeast corner of the intersection of Riley Street and Rome Boulevard in Las Vegas, Nevada. This FPR is intended to address the fire protection and life safety features and requirements for the new skilled nursing facility. The skilled nursing facility will be single-story structure that contains the following: patient rooms, nurse stations, dining areas, recreation areas, offices, conference room, patios, storage rooms, waiting rooms, mechanical rooms, electrical rooms, and associated spaces. The skilled nursing facility is classified as a mixed-used building. The primary occupancies will include Group I-2, A-2, A-3, and B. All work will be performed in accordance with the Southern Nevada Amendments to the 2012 International Building Code (SNBC) as adopted by the City of Las Vegas, AIA guideline for Design and Construction of Hospital and Healthcare Facilities 2006, and the 2012 Southern Nevada Fire Code Amendments to the 2012 International Fire Code (SNFC) as adopted by the City of Las Vegas Fire and Rescue (LVFR). Due to licensing of the property the facility must also comply with NFPA 101, The Life Safety Code. PASSIVE FIRE-RESISTIVE ASPECTS The skilled nursing facility will be single-story structure with a total area of 42,308 ft2. In terms of allowable building area and height, Group I-2 occupancy figures were utilized as it is the most restrictive occupancy in the building. The building is considered an I-2 occupancy as the residents are incapable of self-preservation. The new building will be built of Type VA construction per SNBC Table 503. The building area limited by SNBC Table 503 is permitted to be increased due to the frontage and automatic sprinkler system protection. As such, the maximum allowable area for this building is 45,125 ft2 in accordance with SNBC Section 506. The proposed height and area are within the allowable limits. The code analysis for new skilled nursing facility has been prepared by the architect and detailed on Sheet G-003 of the architectural package. Refer to the code analysis for the calculation associated with the maximum allowable area. The building is classified as mixed-use nonseparated occupancy per SNBC Section As such, there are no requirements for occupancy separations or incidental use separations, except where detailed herein. Incidental use separations per SNBC Section 509 will apply. JBA Las Vegas West Patrick Lane Las Vegas, NV Worldwide Trusted Advisors

2 City of Las Vegas 2 September 15, 2016 Centennial Hills Skilled Nursing Facility JBA Project No Las Vegas, NV The fire-resistance ratings for building elements will apply as provided in Table 1. Table 1: Structural Fire Resistance Ratings for Construction Type V-A Building Element Minimum Fire-Resistance Rating (Hours) Structural frame 1 Bearing walls 1 Non-bearing walls & partitions 0 Floors 1 Roofs 1 Based on SNBC Table 602, exterior walls of Type V-A construction are not required to be fire-resistance rated when the fire separation distance is equal to or greater than 30 feet. The fire separation distance for the new structure will be at least 30 feet in each direction. As such, non-bearing exterior walls will not require a fire-resistance rating due to the fire separation distances. Type V-A construction is permitted to utilize any building materials permitted by the SNBC. Habitable rooms in Group I-2 occupancies are required to have an exit access door leading directly into a corridor per SNBC Section Corridors are required to be continuous to the exits per SNBC Section The waiting rooms, nurse stations, and dining/recreation/activity areas will be constructed as required for corridors, will be provided with automatic fire detection, and will be equipped throughout with quick-response sprinklers.

The building will be provided with a court and will comply with SNBC Section Corridors walls are permitted to be constructed as non-rated smoke partitions per SNBC Section Smoke partitions are required to extend from the top of the foundation or floor below to the underside of the floor or roof sheathing, deck, or slab above and will be constructed in accordance with SNBC Section 710. For this project, the 1-hour roof consists of a bottom membrane beneath the joists such that walls are permitted to terminate at the bottom membrane of the 1-hour fire-resistance rated roof. Penetrations of smoke partitions will be in accordance with SBNC Section Ducts and air transfer openings in smoke partitions will be in accordance with SNBC Section Air transfer openings will require smoke dampers complying with Section Penetrations of the bottom roof membrane will be in accordance with SNBC Section and duct penetrations will be in accordance with SNBC Section Doors located in non-rated corridor walls that are not part of an exit, will not require a fire protection rating and will not be required to be equipped with self-closing or automatic-closing devices. These corridor doors will be required to provide an effective barrier to limit the transfer of smoke, and will be equipped with positive latching. Roller latches will not be permitted. Group I-2 occupancies with an occupant load exceeding 49 occupants are required to be separated into no fewer than two smoke compartments per SNBC Section Smoke compartments are not permitted to exceed 22,500 ft 2. The skilled nursing facility will be separated into two smoke compartments. Smoke compartments are required to be separated from adjacent smoke compartments by 1-hour fire-resistance rated smoke barriers constructed in accordance with SNBC Section 709. Smoke barriers will not be required where the smoke compartment boundary wall is separating the interior of the building from the outside, which includes exterior walls and court walls. Smoke barriers will form an effective membrane continuous from outside wall to outside wall and from below the underside of the floor or roof sheathing, deck or slab above, including continuity though concealed spaces.
