PROJECT NO.

PROJECT DESCRIPTION:

During the development of the subject project, our office determined retaining walls shall be

considered. I am requesting the Structures Division coordinate with the Geotechnical Section to

evaluate each retaining wall to determine if the retaining wall is a feasible option for locations as

shown on the plans and request that they coordinate the acquisition of soil surveys deemed

necessary by the structural designer. Please notify our office immediately if a wall is deemed not

to be a feasible solution.

The retaining wall information shown on the line and grade plans is conceptual in nature; therefore,

any changes to the length, location, or footprint of proposed walls could affect R.O.W. in an

already constrained location. Please note the following R.O.W. restrictions, known

environmental constraints, or project commitments when determining your design and approved

alternatives: (Designer to enter all R.O.W. restrictions, environmental constraints, and/or project

commitments for each wall location here)

The Retaining Wall Detail (R1A.sht, R2A.sht, etc.) Geometric Layout sheet(s) and related files

are on FileNet under the name: nnnnnn-nn-RetainingWall.zip. For all walls, additional

information or changes to all Retaining Wall Detail (R1A.sht, R2A.sht, etc.) Geometric Layout

sheet(s) pertaining to wall length, location, or footprint of the wall shall be provided to the TDOT

Preconstruction Designer or Consultant Designer by this date Click here to enter a date..

(Designer to enter date three weeks prior to the date scheduled to print for the Functional Design Plans Field

Review).

For each wall designed by the Structures Division, the Structures Division shall also provide

Preliminary Retaining Wall Details (R1.sht, R2.sht, etc.) Geotechnical Design Notes sheet(s) for

insertion into the plans for Functional Design Plans field review by this date Click here to enter a date.. (Designer

to enter date one week prior to the date scheduled to print for Functional Design Plans Field Review distribution).

Retaining Wall Details (R1B.sht, R2B.sht,etc.) Soil Profiles and Details sheet(s) shall not be

provided.

For each wall not designed by the Structures Division, the Retaining Wall Details (R1.sht ,

R2.sht, etc.) Geotechnical Design Notes and Retaining Wall Details (R1B.sht, R2B.sht, etc.) Soil

Profiles and Details sheet(s) shall not be provided for the Functional Design Plans Field Review.
