This document contains two technical alignment review reports for the "Design SurvFt" project, generated on January 26, 2026.

The Horizontal Alignment Review Report details the "Main_01" baseline alignment consisting of five geometric elements: an initial linear segment (20.035 feet), a circular curve with a 1,250-foot radius and 4.572° right deflection (99.735 feet long), a second linear segment (141.927 feet), a second circular curve with a 1,500-foot radius and 1.163° left deflection (30.437 feet long), a third linear segment (382.201 feet), a third circular curve with a 780-foot radius and 28.213° left deflection (384.079 feet long), and a final linear segment (86.980 feet). The alignment extends from station 0.000 to station 1,145.394, with coordinates provided for key points (Point of Curvature, Horizontal Point of Intersection, Curve Center, Point of Tangency, and endpoints). Curve parameters include radii, delta angles, degrees of curvature, tangent lengths, chord lengths, middle ordinates, and external distances.

The Vertical Alignment Review Report describes the "Main_01_Pro" vertical profile along the "Primary Alignment3" horizontal baseline, extending from station 10.000 to station 1,119.796 with elevations ranging from 236.450 to 292.170 feet. The profile comprises six symmetrical parabolic vertical curves separated by linear tangent segments with varying grades (ranging from 0.006 to 0.088). Parabolic curve parameters include entrance and exit grades, lengths, K-values, r-values, and middle ordinates. All measurements are in feet unless otherwise specified.
