Notes: 1. This load chart is intended for simple structures supported by columns, posts,and beams loaded up to, but not exceeding,the stated capacities. It is not intended for structures with asymmetrical, rotational,overturning,or dynamic forces. Intended uses are described in section 2.0 of ICC-ES prescriptive bearing evaluation report ESR-1895. For projects that exceed the capacities or limitations defined herein,or the intended uses described in ESR-1895,contact PFI for additional information or site-specific capacity evaluation. See also the Use and Applications download at www.diamondpiers.com. 2. Capacities shown are tested to a Factor of Safety of 2, and are applicable in properly drained, normal sound soils only, with minimum soil bearing capacities as indicated. Copies of the field test reports are available from PFI upon request. 3. See IRC Table R401.4.1,"Presumptive Load-Bearing Values of Foundation Materials,"for a full description of applicable 1500 psf and 2000 psf soil types. For soils below 1500 psf,or soils with unknown characteristics, additional site and design analysis is required. For soils above 2000 psf,the values in this chart shall apply. 4. All capacities use four pins of the specified length per foundation. Pin length includes that portion of the pin embedded within the concrete head. See"Check Your Layout" in the Diamond Pier Installation Manual for more information on pin/pier layout and spacing restrictions. 5. For professional engineers designing for short-term transient loads,contact PFI for further information. ©2018 Pin Foundations,Inc.All Rights Reserved.D000008/01.2018 4810 Pt Fosdick Dr NW,PMB 60 PIN FOUNDATIONS I N C Toll Free: 866-255-9478 Gig Harbor,Washington 98335 Main Office: 253-858-8809 www.pinfoundations.com General Email: info@diamondpiers.com
