Testing was performed in accordance with ASTM E1155 by AAR Testing (working <br /> • under subcontract to Kleinfelder) using an Axiom 1155 Floor Profiler. <br /> • 3.2 APPLICABLE STANDARDS & SPECIFICATIONS <br /> • <br /> • <br /> • The 2020 Design Criteria and Outline Specifications for the Development of AMZL Market <br /> • Refurbishment (MR) Delivery Station (Version 1.4) requires that slab-on-grade floors shall have <br /> • minimum overall flatness/levelness of FF50, FL35, with a minimum local of FF35, FL24, in <br /> • accordance with ASTM E1155. <br /> • <br /> • We understand that a portion of the existing warehouse will be used for robotics, and the site <br /> layout and robotics floor area have not been finalized. Once this area is determined, we <br /> • anticipate performing additional evaluations per Amazon Robotics Floor, Mezzanine, and <br /> • Environment Requirements (Rev 05). These include additional minimum functional floor profile <br /> • requirements based on the specific robotics system being utilized, and typically involving a 3D <br /> • floor scan. We understand that the DWS5 warehouse will utilize H-System (J-Pods) robotics on <br /> Hercules drives. Additional requirements include Flatness, Levelness, and Curvature <br /> • specifications, as well as Surface Roughness, Gloss, and Friction. <br /> • <br /> • RESULTS AND RECOMMENDATIONS <br /> • Floor profile (Flatness/ Levelness) testing was broken up into two separate zones, a south zone <br /> (Surface 1) and a north zone (Surface 2) as illustrated in the MR Floor Flatness Inspection <br /> • Reports presented in Appendix D. The findings of the floor profile testing are summarized in <br /> • Table 2, below. Based on the AMZL MR slab-on-grade requirements and the results of initial <br /> • floor profile testing, the current warehouse floor does not meet the FF and FL requirements. <br /> • <br /> • <br /> • 20203884.001A/SEA20R110164 Page 9 of 28 June 1, 2020 <br /> ©2020 Kleinfelder <br />
