            Step 2
          
        
        
          The
        
        
          New Project
        
        
          page allows the user to choose
        
        
          between the “Helical Piles” or “Helical Tiebacks”
        
        
          modules. The helical piles module is selected to
        
        
          determine capacities of vertical and battered
        
        
          piles in both tension and compression. The
        
        
          helical tiebacks module allows the user to create
        
        
          multiple wall configurations, define the active
        
        
          zone (failure plane) for each wall and determine
        
        
          capacities for multiple rows of tiebacks.
        
        
          The “Helical Piles” button is selected.
        
        
          
            Step 3
          
        
        
          The
        
        
          General Project Information
        
        
          page allows
        
        
          the user to enter project information and select
        
        
          either English or Metric units. The project name
        
        
          and project number are required fields for this
        
        
          page. The buttons at the bottom allow the user
        
        
          to save the information on this page, go back
        
        
          to the previous page or continue to the next
        
        
          page. Information has been entered for the
        
        
          Montgomery Tower project located in St. Louis,
        
        
          MO. Select “Continue” to navigate to the next
        
        
          screen of data entry.
        
        
          
            Step 4
          
        
        
          Required fields on the
        
        
          Soil Profile Inputs
        
        
          page
        
        
          include soil boring ID, depth to groundwater,
        
        
          critical depth and at least one soil layer. Seven
        
        
          soil types are available including sand, clay,
        
        
          mixed, organics, sand fill, clay fill and mixed fill.
        
        
          Soil strength parameter fields for clay, sand, clay
        
        
          fill and sand fill are populated automatically by
        
        
          correlation to SPT N-values; however, the user can
        
        
          manually override these values by entering new
        
        
          data. Selection of organic or mixed soils requires
        
        
          manual entry of the soil strength parameters. The
        
        
          soil profile is graphically displayed as the data
        
        
          is entered. Multiple borings can be entered and
        
        
          saved. The help menu is accessed by clicking
        
        
          on the question mark icons next to various entry
        
        
          fields. In this example, the user has entered and
        
        
          saved the information from Boring B-1 and is
        
        
          ready to continue to the next page.
        
        
          
            Step 5
          
        
        
          The
        
        
          Pile Design Inputs
        
        
          page requires input for
        
        
          boring ID, pile ID, pile shaft type, helix plate
        
        
          configuration and geometry, pile length, batter
        
        
          angle and pile head depth. After required fields
