This publication provides guidance on general policies and procedures that are to be followed by geotechnical engineers in the planning, design, construction, and maintenance of the Tennessee Department of Transportation's (TDOT) roadway and structural systems.
This document establishes uniform procedures for geotechnical services provided by the Tennessee Department of Transportation (TDOT) and its Geotechnical Engineering Section (GES). It outlines the scope of work, organizational structure, and the relationship between these guidelines and other recognized TDOT reference documents like the Design Guidelines and Standard Specifications.
The guidelines cover various aspects of geotechnical work, including roadway design deliveries, structural foundation reports, and operations maintenance support. They provide specific instructions on project numbering systems (PIN, GES File Number, PE numbers) to ensure consistent tracking and communication across TDOT projects.
The PIN number is the unique identifier assigned to a project that must be used in all subsequent documents, including the subject lines of emails, letters, and memoranda.
The fiscal year begins on July 1 and ends on June 30.
Geotechnical work performed for new projects is charged to the PE-N with Code 0 until ROW plans are issued.
