NEW HEWITT/HODGES ASSOCIATES, LLC age 8 HODGES BUILDING—ELEVATOR HOISTWAY ALTERATION January 12, 2017 Review of Fire-Resistive Construction Provisions IFC Section 703.2 requires opening protectives to be maintained in an operable condition. Section 1103.1 of the IFC states, "The provisions of this chapter shall not be construed to allow... a reduction in the level of fire safety provided in buildings constructed in accordance with previously adopted codes." A door at the Level 2 landing would provide some level of safety for the residential levels in the event of a fire conditions in the main lobby space. Therefore, based on the IFC Sections 703.2 and 1103.1, opening protection to the main lobby space should continue to be provided at the Level 2 stair landing. CONCLUSION When appropriate FRR construction and opening protection separate Level 1 from the Basement and Level 2, the stair between Levels 1 and 2 should continue to be open to the main lobby space based on the provisions of IBC Section 3404.1 and Exception 1 to Section 1027.1. New construction providing separation for the stair at Level 2 should support the level of FRR protection established for the stairs serving the upper building levels and also serve to maintain the continuity of the Level 2 corridor per IBC Section 1018.6. STAIR FROM LEVELS 2 THROUGH 5 The interior stairway serving the upper building levels wraps around the elevator hoistway from Level 2 through Level 5. OBSERVATIONS The flight up begins on the east side of the elevator hoistway, the flight down on the south side. These stair segments are joined by an L-shaped corridor element which occurs on the north and west sides of the hoistway, and serves as the elevator landing and stairway landing. Doors to three units are accessed via this corridor segment; 6 other units access the corridor to the south. Similar to the condition observed at Level 2 as described in the section above, doors were absent from the doorway at the top of each flight of stairs up through Level 5. At Levels 2 through 5, from the corner of that doorway, a wall with a cross-corridor door extends to separate the corridor to the south and form the existing helical,stair shaft atrium condition. Labels of unit doors and frames were generally obscured by paint. Markings of labels for a couple of the unit doors which appeared to have been recently installed indicated 90-minute FRR. This is consistent with the notes recorded September 15, 2014 with Permit B1401-024 which identify a 2-hour stair shaft. AEGIS Engineering, PLLC
