About this file
The document is a Horizontal Alignment Review Report for the Design SurvFt project, created on August 29, 2025. The report provides detailed technical specifications for an alignment named ALI-MAIN-01, which consists of three primary elements: two linear segments and two circular curve segments. The alignment begins at coordinates (85428.86, 1952786.965, 2471072.560) and progresses through multiple points with specific northing and easting coordinates, using different tangential directions and curve characteristics. The first circular element has a radius of 2,350 feet with a delta angle of 10.116° to the right, while the second circular element has a significantly larger radius of 95,970 feet with a minimal delta angle of 0.300° to the right. The report includes precise measurements such as tangent lengths, chord directions, middle ordinates, and external measurements for each alignment element.
