Standard Road Plan LI-211 (2).pdf

The document is a Standard Road Plan (LI-211) from the Iowa Department of Transportation (Iowa DOT) detailing technical specifications for a Slip-Base for Light Poles. The technical drawing provides a comprehensive assembly diagram and detailed schematic views of a light pole mounting system, including plan, elevation, and sectional views of the slip-base components.

The slip-base design includes multiple technical specifications and hardware components, such as a triangular anchor plate, keeper plate, top and bottom slip-base plates, and various fasteners. Key installation requirements include using 1" anchor bolts, 1" x 4" high-strength bolts, wire fabric closure, and specific torque specifications (1000 in. lbs). The plan specifies material requirements like galvanized steel for certain components, 28-gauge sheet steel for the keeper plate, and includes precise measurements for bolt circles, hole diameters, and plate dimensions to ensure proper installation and structural integrity of light pole mounting systems.
