Design Criteria <br />I. Applicable Codes <br />-California Building Code (CBC) 2022 <br />-ASCE 7-16 <br />-TIA 222-H <br />-AISC 360-16 <br />-AISC 341-16 <br />-ACI 318-19 <br /> <br />II. Scope of Work <br />This project consists of replacing existing antennas with new antennas. All antennas will be mounted <br />onto new antenna mounts attached to the existing concrete walls of the building. New frp screen <br />enclosures will be installed around the new antennas. Additionally, we will be replacing an existing <br />equipment cabinet with a new cabinet in the equipment room. <br /> <br />Equipment Cabinet: <br /> <br />1.

Provisions of Analysis & Disclaimer <br /> <br />Our structural calculations are completed assuming all information provided to us is accurate and <br />applicable to this site. For the purposes of calculations, we assume an overall structure condition of <br />“like new” and all members, connections, anchors, and surfaces to be free of corrosion and/or <br />structural defects. The structure owner and/or contractor shall verify the structure’s condition prior <br />to installation of any proposed equipment. If actual conditions differ from those described in this <br />report, the Engineer of record should be notified immediately to complete a revised evaluation. <br />AT&T <br />CLU3418 <br />1 of 39
