About this file
This is a solar design attachment document prepared by Ameresco for the Utah Communications Authority (UCA) Parker Mountain Radio Tower and Shelter Installation project located in Piute County, Utah. The document contains detailed engineering drawings and specifications for a solar panel mounting system utilizing LG405N2T modules mounted at a 55-degree angle. The design includes comprehensive technical specifications for structural components such as strongbacks, rail brackets, mounting feet, pipe infrastructure, and ballast blocks with concrete bases. The system is engineered to accommodate 125 mile-per-hour maximum wind speeds and is designed for Exposure C conditions with 2,500 PSI concrete specifications. Key specifications include module dimensions of approximately 79.7 inches in length and 40.3 inches in width, with mounting hardware consisting of galvanized bent anchor bolts, U-bolts, and reinforcement rebar. The design document, dated August 1, 2024, consists of three detailed sheets showing side views, front views, section details, and ballast block construction requirements, with quantities specified for various components including 10 two-hole brackets, 4 three-hole brackets, and ballast blocks requiring 11 rectangular ties and 8 pieces of #4 rebar per block.
The drawings were prepared by Randy C at Ameresco's Albuquerque, New Mexico location (2615 Princeton Drive NE, Albuquerque, New Mexico 87107) under project designation SR-BTTRGR12-T21-LG405N2T-55DEG-V3. The document provides installation-specific notes indicating that certain components including pipe caps, pipe installations, and anchor bolts are to be provided by the installer. The design assumes concrete base construction as shown in the detailed sections, with specific spacing requirements and bolt configurations detailed for both north and south end installations. This technical specification document serves as a supporting exhibit for the UCA procurement, with questions due by May 29, 2026, and submissions due by June 4, 2026.
