EXHIBIT_C_-_JMMU_MAT54_MAT56__MAT58___AT60_CROSS-SECTION.pdf

This file is a technical cross-section exhibit for the JMMU MV54, MV56, MV58, and MV60 rail infrastructure projects. The document presents a detailed engineering diagram (Scale 1:40) showing the track bed construction specifications and requirements for a service road with a 4.4-meter minimum width.

The cross-section specifies critical construction elements including a 12.2-meter front target berm with 1% slope, timber ties measuring 175mm x 225mm x 2.6m at a minimum 10 timbers below sub-grade, and a 72-inch deep timber face on the left embankment. The ballast layer requires removal of 10 inches of existing ballast material (highlighted in yellow on the diagram) and replacement with Grade 2 ballast. Additional specifications include a 1.734-meter track depth, 100mm ballast layer, geogrid filter fabric installation, and a 2% slope on both sides of the track bed. The right side service road area incorporates 300mm compacted subgrade (90% compaction) with 125mm Grade 6 material and 75mm Type AA surface layer. Foundation support includes an HP 200x54 steel H-pile driven to 2.7 meters below the target subgrade elevation. The diagram also references vertical control point data from Target Data Sheet C-199 and indicates track and tie installation by others, establishing baseline construction standards for this rail corridor project.
