Retaining Wall Manual and Policy

As part of an effort to improve the quality of retaining wall projects in the State of Tennessee, the Geotechnical Engineering Section has implemented a retaining wall policy and manual - the Tennessee Department of Transportation Earth Retaining Structures Manual.

The manual has been established to meet the following objectives:

  • To obtain statewide uniformity
  • Establish standard procedures and delineate responsibility for the preparation and review of plans
  • Design and construction control of earth retaining structures

In addition, it is the intent of this policy to initiate a process for review and approval for both permanent and critical temporary proprietary wall systems so that a list of approved wall systems can be established. A critical temporary wall is one that is necessary to maintain the safety of the traveling public or structural integrity of nearby structures and utilities for the duration of the construction contract.
