PHASE V: CONSTRUCTION

  • -Set slope and grade stakes; clear and grub site - grading
    and excavation - demolition of structures

  • -Stake-out centerline and subgrade stakes - install drainage
    structures and lighting

    • 4

    Page 4

  • -Grade ditches and final grading of slopes

  • -Lay down subbase material - grade shoulders

  • -Install curbs - rake to subgrade, spread topsoil, seed
    and plant

  • -Lay down base course - lay down surface course, stall lighting,
    erect roadside signs

  • -Hold pre-final inspection - write up punchlist - final finishing
