About this file
The Vertical Alignment Review Report is a technical document for the Design SurvFt project, dated July 18, 2025. The report details the horizontal and vertical alignment specifications for a road or infrastructure project at Milestone Point (MP) 25.3, using an Alignment\Baseline style. The vertical alignment consists of multiple linear and symmetrical parabola elements with varying tangent grades ranging from -0.033 to -0.017. The report provides precise station and elevation data, including start and end points, vertical points of curvature (VPC), vertical points of intersection (VPI), and vertical points of tangency (VPT), with all measurements recorded in feet. The document includes detailed calculations such as length, entrance and exit grades, and parameters like r and K values for the alignment elements.
