Lowell Seismic-certified Enclosed Rack - 27"D Description: The LSER seismic-certified enclosed rack is Professional Engineer (P.E.) certified to meet or exceed the seismic design requirements as specified in the 2009 International Building Code (IBC), Section 1613; the 2007 California Building Code (CBC), Section 1613; and California's Office of Statewide Health Planning and Development (OSHPD). Specifically, the LSER rack is seismic qualified and certified for two (2) categories of seismic qualification (see below) with individual downloadable document packages for IBC, CBC, and OSHPD.Qualified seismic categories: 1. Racks identified as part of a Life Safety/Essential System (Ip = 1.5). These racks are so designated and required in critical or essential facilities where operation and function following a major earthquake event is necessary. See IBC and CBC document packages. 2. Racks requiring seismic design 'Anchorage' by code (Ip = 1.0), but are NOT identified as a Life Safety/Essential System. These racks only require their supports and attachments; i.e., anchorage, to be seismically qualified and certified. See IBC, CBC and OSHPD document packages. The enclosed rack is welded 16-gauge steel with a 14-gauge steel bottom with welded brackets in each corner of the base, holes for anchors (by others), reinforcements at loadbearing junctures for strength equivalent to 11-ga. steel, and P.E. certified documents. Note: Installation requirements vary based on application and may require front and rear 1U braces and a second set of mounting rails installed at the factory refer to IBC, CBC and OSHPD document packages and specify the code to which your rack must comply when ordering.
P.E. Certified documents for IBC, CBC or OSHPD
