13 h <br /> Botesch, Nash & Hall <br /> Architects, P.S. <br /> October 11, 2016 <br /> City of Everett Permit Services <br /> 3200 Cedar Street <br /> Everett, WA 98201 <br /> Attn: Meg Haley <br /> RE: Providence Hospital, Pacific Campus <br /> Children's Center Outdoor Canopy <br /> Code Study/Alternate Means and Methods <br /> Dear Meg, <br /> This code study shall supplement the permit set drawings submitted for plan review. It shall <br /> also serve to provide an explanation of meeting the `intent of the code' as outlined in the 2015 <br /> IBC Section 104.11 Alternative Materials, Design and Methods of Construction and Equipment. <br /> As you know we had worked with both you and Tony Lee for many months regarding what <br /> would be an acceptable solution for the design of the Providence Children's Center outdoor play <br /> area canopy that would meet the intent of the code. Our code study is based on the following: <br /> Existing First Floor Building Occupancy: 'B' <br /> Existing Building Construction Type: Type IA Sprinkled <br /> Proposed Canopy Construction Type: Type IA <br /> Exterior Wall and Opening Protection Required: Not Required <br /> The proposed outdoor play area canopy is proposed as an 'accessory use' to the `B' occupancy <br /> Children's Center meeting the requirements of Section 508.2. <br /> 1) 508.2.2 Allowable Building Height— Unlimited <br /> 2) 508.2.3 Allowable Building Area —The existing building First Floor total area is <br /> 27,481 SF. The proposed canopy is less than 10% of the story floor area as it is <br /> 2,600 SF. <br /> Section 705.3 Buildings on the same lot does not apply as the canopy is considered an <br /> 'accessory use' to the existing 'B' Occupancy as referenced to Section 508.2, therefore no <br /> separation is required. <br /> The proposed canopy structure per the drawings consists of concrete footings, a primary and <br /> secondary roof steel framing and non-combustible polycarbonate translucent Class A roof <br /> panels. NFPA 13, Section 8.14.7.2 allows omission of a sprinkler system under the canopy due <br /> to the noncombustible construction. <br /> Type IA Construction Requirements (Table 601): <br /> 1) Primary Framing 2 Hours (601 a.) <br /> 2) Roof Construction for Secondary Members 1.5 Hours <br /> Page taf..2 <br />
