. . <br /> Mr. Tim Tyler <br /> Page 2 <br /> June 19, 1991 <br /> 2. �istinq Corridors and A.quir•a azits <br /> A. Please see the attached floor plans that have been colored <br /> to indicate one-hour smoke, one-hour, two-fiour, and four- <br /> hour seperations. If these plans are acceptable, please <br /> return them to our office so we may incorporate them into <br /> the conetruction documents. <br /> The one-hour smoke aeparations have been indicated vith <br /> the color purple. The areas within each emoke compartment <br /> and adjacent emoke compartwent are as follows: <br /> tiain Floor Emerqency Department 13,023 sf <br /> !lain Floor Adjacent Compartment 17,760 sf <br /> First Floor Surqery Department 18,942 sf <br /> First Floor 1ldjacant �o�epartment 15,510 sf <br /> 1111 of the above square footaqes are within the allowable <br /> 22,500 square foot waxinum, according to UBC Section 1002 <br /> (b) . The maximum dimension is the east-west dimension of <br /> Surqery and is 150 feet. <br /> The requirement in Section 1002 (b) that requires each <br /> conpartment to have the capacity to hold the occnpanta of <br /> the adjacent compartw�ent ie intended to protect both <br /> ambulatory and nonambulatory patients for a sufficient <br /> amount of time to provide exitinq from that iloor and <br /> buildinq. The ebove adjacent aquare footaqes indicate <br /> more than an adequate capacity. To illustrate this, <br /> suppose that every bed in the Surgery Depertment is <br /> occupied includinq each operatinq room, even though this <br /> is functionally impossible. This Would total �6 non- <br /> ewbuletory patients at 30 square feet each and equals <br /> 1,080 equare feet. In addition, assume that iE there are <br /> two additional occupants for each nonambulatory patient et <br /> 6 square feet each, this equale 412 square feet. The <br /> total space tequired in the adjacent compartment would be <br /> 1,512 square feet. It also ehould be noted that the <br /> adjacent emoke cowpartwants to both Emergency and Surqery <br /> Departn�ents have direct exitinq to the exterior qrada as <br /> well as additionnl smoke compartments within the 8outh <br /> Ninq. The doors defininq swoke con�partments will be <br /> tiqht-fit;:inq, swoke- and draft-control assemblies, and <br /> fire-protection reted to 20 minutes. When installed <br /> across a corridor, they shall be double egress without <br /> center mullion and shall e�eet all additional requirements <br /> of Section 1002 (b) . <br /> B. The one-hour corridors have been indicated vith the color <br /> red, in the previous meetings, we requested that you <br />
