# S4 -- Terrain Verification

Verify existing ground and set reference hubs

  -----------------------------------------------------------------------
  *The following list of typical tasks is based on and supplement the
  documents referenced in Section V of this SOW and the CFLHD Standard P3
  Template Activities. However, it may be appropriate to add, delete, or
  modify tasks to meet project specific requirements.*

  -----------------------------------------------------------------------

1.  Check existing control in accordance with Standards and
    Specifications for S4.

  -----------------------------------------------------------------------
  *Assume the total number of design cross sections. Additional cross
  sections are required for curves with radii less than 500 feet (150 m),
  changes in the typical section (including guardrail, drainage features,
  etc.), retaining walls, etc.*

  -----------------------------------------------------------------------

2.  Set centerline points, left and right reference hubs and measure
    cross sections at stations to coincide with the design
    cross-sections in accordance with [Standards and Specifications for
    S4]{.mark}. For this project it is assumed that there will be
    approximately XX design cross sections.

3.  Incorporate cross section and reference hub data into the existing
    design cross sections in accordance with [Standards and
    Specifications for S4]{.mark}.

4.  Provide supplemental control in accordance with [Standards and
    Specifications for S4]{.mark}.

5.  Update the control sheet to include supplemental control points.

6.  Update the mapping file to include supplemental control.

Deliverables for S4

  -----------------------------------------------------------------------
  *Add/delete deliverables to correspond to the tasks above. Coordinate
  number of copies with COTR. Number of copies and submittal dates shall
  be shown in Section IV, Deliverables and Schedule.*

  -----------------------------------------------------------------------

-   None

The following data is to be retained by the A/E unless requested by the
COTR:

-   Cross-sectional data in GEOPAK® (SOE) station offset elevation
    format as follows:

    -   Station,Offset,Elevation,Northing,Easting,Pcode.

    -   Reference hubs shall be designated as RH for the p-code and
        centerline points shall be designated as CL.

    -   No other p-codes are to be used.

    -   The file shall be in ASCII format with a header record in the
        file that defines the fields.

    -   The extension shall be .SOE.

-   MicroStation® design cross-section file with cross section and
    reference hub data incorporated.

-   All raw observations (slope distance, zenith angle, horizontal
    angles and instrument and target heights) made to establish the
    supplemental control points and existing control checks in digital
    format.

-   Star\*Net adjustment files to include .dat input files and final
    adjustment .lst file.

-   Updated MicroStation mapping file to include supplemental control.

-   Legible copies of all field notes

The final submittal of all files shall be delivered on a CD/DVD, labeled
with the Project Designation, Project Name and Final Submittal, i.e.
*"CA PFH 112-1(1)", South Fork Smith River, Final Submittal"*. Progress
submittals may be submitted via e-mail, CFLHD FTP Site or CD/DVD. All
file names shall begin with the *"Project Designation".* The remaining
characters shall be descriptive of the fieldwork contained in the file.
The first line of each file shall be a header describing each field
within the file.
