Checklist and Guidelines for Review of Geotechnical
Reports and Preliminary Plans and Specifications

GTR Review Checklist for Centerline Cuts and Embankments

B. Centerline Cuts and Embankments

 (Pgs. 2-2 to 2-6)

In addition to the basic information listed in Section A, is the following information provided in the project geotechnical report.

Are station-to-station descriptions included for:

  1. Existing surface and subsurface drainage?

        (Yes   /   No   /   Unknown or N/A)

  2. Evidence of springs and excessively wet areas?

        (Yes   /   No   /   Unknown or N/A)

  3. Slides, slumps, and faults noted along the alignment?

        (Yes   /   No   /   Unknown or N/A)

Are station-to-station recommendations included for the following?

General Soil Cut or Fill
  1. Specific surface/subsurface drainage recommendations?

        (Yes   /   No   /   Unknown or N/A)

  2. Excavation limits of unsuitable materials?

        (Yes   /   No   /   Unknown or N/A)

  3. *Erosion protection measures for back slopes, side slopes, and ditches, including riprap recommendations or special slope treatment.

        (Yes   /   No   /   Unknown or N/A)

Soil Cuts
 (Pgs. 5-23, 5-24)
  1. *Recommended cut slope design?

        (Yes   /   No   /   Unknown or N/A)

  2. Are clay cut slopes designed for minimum F.S. = 1.50?

        (Yes   /   No   /   Unknown or N/A)

  3. Special usage of excavated soils?

        (Yes   /   No   /   Unknown or N/A)

  4. Estimated shrink-swell factors for excavated materials?

        (Yes   /   No   /   Unknown or N/A)

  5. If answer to 3 is yes, are recommendations provided for design treatment?

        (Yes   /   No   /   Unknown or N/A)

Fills
 (Pgs. 5-1 to 5-3)
  1. Recommended fill slope design?

        (Yes   /   No   /   Unknown or N/A)

  2. Will fill slope design provide minimum F.S. = 1.25?

        (Yes   /   No   /   Unknown or N/A)

Rock Slopes
  1. *Are recommended slope designs and blasting specifications provided?

        (Yes   /   No   /   Unknown or N/A)

  2. *Is the need for special rock slope Stabilization measures, e.g., rockfall catch ditch, wire mesh slope protection, shotcrete, rock bolts, addressed?

        (Yes   /   No   /   Unknown or N/A)

  3. Has the use of "template" designs been avoided (such as designing all rock slopes on 0.25:1 rather than designing based on orientation of major rock jointing)?

        (Yes   /   No   /   Unknown or N/A)

  4. *Have effects of blast induced vibrations on adjacent structures been evaluated?

        (Yes   /   No   /   Unknown or N/A)

*A response other than (yes) or (N/A) for any of these checklist questions is cause to contact the appropriate geotechnical engineer for a clarification and/or to discuss the project.
