December 7, 2022 <br />Mr. Ian DeMello <br />Shubin & Bass, PA <br />46 S.W 1St Street, Third Floor <br />Miami, FL 33130 <br />Re: Report for Concrete Core Physical and Chemical Analyses <br />334 Atlantic Avenue <br />334 Atlantic Ave <br />Sunny Isles Beach, Florida 33160 <br />NV5 Project No.: 18005.00 <br />Dear Mr. DeMello: <br />NV5, Inc. submits this report in fulfillment of the scope of services described in our proposal 22-0975 <br />dated October 25, 2022. This report contains the data collected and describes the procedures used. <br />PROJECT INFORMATION <br />The project site is located at 334 Atlantic Ave, Sunny Isles Beach, Florida. The site is bounded by a <br />single-family home to the east, by Atlantic Isle Road to the north, and by Biscayne Bay to the south and <br />west. The site is approximately trapezoidal in shape. <br />PURPOSE <br />The purpose of our services on this project is to perform laboratory compressive strength and chemical <br />analyses on the concrete core and present a report summarizing the results. <br />SAMPLE COLLECTION <br />NV5 was instructed by the client to retrieve cores from three different structural elements. A Ground <br />Penetrating Radar (GPR) was performed to determine the adequate locations to extract the cores. Five <br />(5) cores were extracted by NV5 personnel and were bagged within the time limit indicated I ASTM <br />C42-20 and transported to NV5 laboratory for testing. The core locations are summarized in Table 1. <br />The concrete cores dimensions were 2.77 -inches in diameter and varied in length from 5.92- to 6.98 - <br />inches. We note that the concrete cores diameter is less than that recommended in ASTM C42 <br />Standard Test Method for Obtaining and Testing Drilled Cores and Sawed Beams of Concrete. <br />14486 Commerce Way I Miami Lakes, FL 33016 1 www.NV5.com I Office 305.666.3563 1 Fax 305.666.3069 <br />CONSTRUCTION QUALITY ASSURANCE - INFRASTRUCTURE - ENERGY - PROGRAM MANAGEMENT - ENVIRONMENTAL <br />Page 33 of 98 44 <br />
