Best regards, Andrew Ordway, PE Engineer O D M E. Colorado Blvd., Suite 200 Pasadena, CA From: Andrew Ordway Sent: Tuesday, June 28, :47 PM To: Bradford Brewer (bbrewer@nacarchitecture.com) Cc: Jorge Rivera (Jorge.Rivera@kpff.com) Subject: FW: Fall Arrest Beam Elevation Hi Brad, As discussed, please see the confirmation below from Kone regarding the permitted installation height for the fall arrest beam. Structurally we would recommend that the top and bottom of the fall arrest beam both beam installed 3" min from the top and bottom of the supporting roof framing to allow for welding access to install the connection. Best regards, Andrew Ordway, PE Engineer O D M E. Colorado Blvd., Suite 200 Pasadena, CA From: Grooters Troy [mailto:troy.grooters@kone.com] Sent: Tuesday, June 28, :41 PM To: Andrew Ordway Subject: RE: Fall Arrest Beam Elevation 1

4 Correct cannot be below the hoist beam profile or it interferes with the minimum overhead dimension. If it is higher than the profile of the hoist beam we begin to worry about access for the field mechanics. Troy Grooters District Installation Manager Los Angeles KONE Knott Ave, Suite B Cypress, CA Tel Mobile troy.grooters@kone.com From: Andrew Ordway [mailto:andrew.ordway@kpff.com] Sent: Tuesday, June 28, :14 PM To: Grooters Troy <Troy.Grooters@kone.com> Subject: Fall Arrest Beam Elevation Hi Troy, Thanks for your help today. I'm following up on our phone conversation to get a confirmation for the project architect (for Jefferson Elementary School ORG) indicating that installation of the fall arrest beam at any elevation within the depth of the hoistway beam will be okay. Note: This will relieve the requirement specified in note #13, which requires that the bottom of fall arrest beam be aligned to bottom of hoistway beam. Thank you, Andrew Ordway, PE Engineer O D M E.
