Overhead/Subsurface Utility Engineering (SUE)

Prequalification in Area Class 5.08 SUE is required for Consultants who are interested in being considered for a GDOT Contract. Refer to the current Consultant Prequalification Manual for the minimum requirements of this Area Class.


Overhead/Subsurface Utility Engineering (SUE) is defined as the engineering processes that involve managing certain risks associated with accurately and comprehensively identifying, characterizing, and mapping overhead and underground utility facilities. The benefits include:

  • Accurate and timely utility information to the roadway designer
  • Possible reduction in utility relocation costs by allowing the designer to make informed design decisions around potential utility conflicts
  • Possible reduction in unexpected conflicts with utilities which can cause construction delays, damages, service disruptions, claims, and even injuries or lost lives

Current Program Status

Future Requests for Statement of Qualifications will be published at the DOAS Procurement Site.  Refer to the "Supplier's Guide to eSource" on the DOAS site for instructions for registering to receive automatic notifications.  

Design Aids and Guidelines For GDOT SUE Consultants

Listed below are design aids and guidelines that are to be used when performing SUE work for GDOT. These have been put in place to ensure the following:

  • Proper coordination with Department Personnel
  • Adherence to the Department's Plan Development Process
  • Quality SUE Deliverables

GDOT Microstation Workspace - The GDOT is currently supporting Microstation versions J and V8i.  All SUE Consultants need to ensure they are using the appropriate  Workspace that is applicable to the project's scope.  The Workspaces include the current custom menus, cell libraries, and linestyles that are employed and required when preparing plans for the Department.

Electronic Data Guidelines (EDG) - The GDOT is currently supporting an EDG for each of the versions of Microstation mentioned above.  All SUE Consultants need to adhere to the appropriate version, based on the project's scope, to ensure that all work is prepared in accordance to the most current GDOT Standards.

SUE Scope of Services - This is the current SUE Scope of Services to be included in all GDOT contracts utilizing SUE.

SUE Submittal, Review, & Acceptance Process - This flowchart illustrates the typical process followed when the Prequalified SUE Consultant submits their SUE Deliverables to GDOT for review.

SUE Subconsultant Project Workflow - This flowchart illustrates the typical process to be followed when the Prequalified SUE Consultant is Sub to a Prime.

SUE Subconsultant Bi-Monthly Status Report - This report is to be completed and submitted (bi-monthly) by all Prequalified SUE Consultants performing SUE work as Sub to a Prime to ensure coordination with GDOT's Plan Development Process.

SUE Deliverables Checklists - Separate Checklists (.docx files) for each type of SUE Deliverable offering the current minimum requirements for GDOT SUE projects are available on GDOT's FileEXchange under the "Utilities\Downloads\SUE\SUEDeliverablesChecklists" folder.

Utility Impact Analysis (UIA) Conflict Matrix - 2 sample blank spreadsheets (.xls, .xlsx) for use in creating a SUE Utility Impact Analysis (UIA) Conflict Matrix are available on GDOT's FileEXchange under the "Utilities\Downloads\SUE\SUEConflictMatrix" folder.

Sample SUE Deliverables (dgns) - (Coming soon.)

Avoiding Utility Project Impacts (GDOT Portion Only) - This is the GDOT portion of the SUE Training entitled "Avoiding Utility Project Impacts". It contains information on identifying and requesting SUE Services, optimizing project development to avoid utility impacts, and a sample Conflict Matrix. Please refer to GDOT's Transportation Engineering Professional Training website for current available training schedules.
