Use of SUE to Improve Early Stage Project Development
Edgar Kraus and Cesar Quiroga 2011 Short Course College Station

Today’s Presentation
• What is SUE? • How can SUE help improve project development? • What are SUE best practices?

Transportation Operations Group
What is SUE?
• Subsurface Utility Engineering • Provides utility data
5
Transportation Operations Group
Utility Data Quality Levels
• QLD • QLC • QLB • QLA • ASCE/CI 38-02
Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data
Transportation Operations Group
Quality Levels
• QLD: Data collection from existing records or oral recollections
• QLC: Surveying and plotting visible utility appurtenances and making inferences about underground linear utility facilities that connect those appurtenances
Transportation Operations Group
Quality Levels
• QLB: Surface geophysical methods to determine the approximate horizontal position of subsurface utilities
Transportation Operations Group
Quality Levels
• QLA: Accurate horizontal and vertical utility locations through exposure of underground utility facilities at certain locations
Why SUE? Pros Cons
• Avoid utility conflicts • Avoid cost overruns • Avoid project delays • Nationally documented
cost benefit
• Costs money • The more detailed, the
more expensive

Key: Knowing when and how to use SUE
Transportation Operations Group
Best Practices for Utility Investigations
• TxDOT survey • Review best practices in other states • Review TxDOT project data
• Identify state of the practice, trends, best practices
13
Transportation Operations Group
Is TxDOT using SUE?
• Yes • QLD (“record search”): standard practice • QLC (“surveying”): often • QLB (“geophysical methods”): infrequently • QLA (“test holes”): infrequently
14
Transportation Operations Group
What’s TxDOT’s Take on SUE?
• Overall high satisfaction with SUE deliverables • Uncertainty about how to use/inexperience with
technology • Uncertainty about benefit • Some challenges with expectations (quality,
accuracy, and scheduling) • Lack of funding
Transportation Operations Group
TxDOT Survey Results
• Need for education and training ◦ SUE benefits (designers are unaware of benefits)
◦ when and how to use SUE in the project development process
• Lack of consistent policies or procedures in using SUE • Scarce use of criteria or scoring for utilities and SUE • Project managers/designer exclude SUE because of
project costs as a matter of district policy • Quality of SUE providers and SUE work is inconsistent • Lack of “best practices” cited by designers and project
managers
16

Best Practices: Usage/Implementation Areas
• Policy approaches • Education and Training • Procurement and contracting • Project development process • Technology and information systems

In Summary…
• SUE can help avoid utility conflicts, cost overruns, delays
• All districts are already doing (some) SUE • Few districts take full advantage of SUE • Best practices for SUE can help get the most out of
SUE
