40 <br /> • <br /> NEW HEWITT/HODGES ASSOCIATES,LLC age <br /> HODGES BUILDING—ELEVATOR HOISTWAY ALTERATION January 12, 201 <br /> Review of Fire-Resistive Construction Provisions <br /> PROJECT CONDITIONS <br /> The existing elevator is being replaced to enlarge the hoistway in order to comply with <br /> current code requirements for gurney access.The interior stair wraps around the elevator <br /> hoistway and is necessarily displaced with the enlargement of the hoistway. With the <br /> proposed alterations and improvements,two existing walls of the stair and elevator will <br /> remain, and be extended with new construction to achieve the level of safety prescribed for <br /> the existing construction. <br /> Comments pertaining to existing conditions are based on non-destructive visual <br /> observations during my visit to the building with Doug Engleson on November 10,2016. <br /> ELEVATOR HOISTWAY <br /> An unprotected opening into the elevator pit at the basement level provided eme ability to <br /> view the apparent construction of the existing elevator hoistway walls.The hoistway <br /> extends up through the 5-story building to the machine room at the attic level. In a reply <br /> sent via e-mail to Doug Engleson November 15, 2016, Meg Haley(City of Everett, Building <br /> Plan Review)referenced applicability of IFC Section 1103.4.3. This provision prescribes <br /> minimum 1-hour fire-resistance-rated (FRR) protection for interior vertical openings <br /> connecting more than 5 stories. <br /> Therefore, it appears that City of Everett recognizes this elevator hoistway connects more <br /> than 5 stories.While this would require appropriate protection of the existing condition <br /> observed in the basement,the opening noted above occurred in a wall which is being <br /> relocated as a part of the elevator improvement project. <br /> EXISTING HOISTWAY CONSTRUCTION <br /> The existing walls of the elevator hoistway which will remain are required to be of 1-hour <br /> FRR construction as required by IFC Section 1103.4.3. <br /> OBSERVATIONS, <br /> Existing construction visible at the base of the elevator hoistway as well as at the top of the <br /> shaft beneath the elevator machine room floor appeared to be solid 2x4 framing members <br /> installed flat-to-flat for a framing thickness of 4 inches. <br /> Plaster appeared to be applied over the exterior of the framing, except within the interstitial <br /> floor cavity of the elevator machine room.Plaster also appeared to be applied over the <br /> interior of the hoistway framing, though some limited areas of exposed framing were visible <br /> within the elevator pitwhere a portion of the plaster finish was no longer in place. <br /> AEGIS Engineering, PLLC <br />
