1. SHRP 2 Utilities Research PRODUCTS 2011 AASHTO RAC/TRB State Reps Annual Meeting Chuck Taylor

2. TOPICS • What is SHRP 2 and How Does It Work? • Why Are We Spending FHWA $ on Utilities? • Objectives , Status, Products of the Four Utilities Projects

3. SHRP 2 • Authorized by Congress in 2005 • Funding Became Available in 2006 • Conducted under a memo of understanding among AASHTO, FHWA, National Academies (TRB) • Funds Provided through FHWA • Program Recently Extended to 3/31/15 • Current Budget is $218 Million

5. Why Is FHWA Funding Utilities Research? Survey of state DOTs, highway contractors, design consultants identified utility relocations as the most frequent cause for delays in highway construction.

6. The Problem • Can’t rely on utility owners for accurate location information • Designers in the past had little knowledge of utility issues and their costs • Utilities expensive to relocate • Over 11 million miles of underground utilities in the U.S. • More being installed daily, deeper and with less detectable materials • At varied depths, soils, materials, sizes, with varied access

7. The Research Process • Survey user community. We established User Panels for all projects • Panels help develop user requirements & specs • Provide critical review of products while under development • Develop prototypes • Field test prototypes • Develop user manuals and training material

8. Multi-Sensor Platforms for Locating Underground Utilities (R01-B) • GPR, Electromagnetic (EMI), & Seismic Reflection Platforms • Significant Advances in Detection & Location from the Surface • Across a wide Range of Soil Types & Site Conditions • Able to Also Detect Existing Electronic Marker & Transponder Signals • One-Year Field Test

9. Multi-Sensor Platforms (R01-B)Gary Young, PI, Underground Imaging Technologies • Goal: Combine GPR, EM, and Seismics on one towed platform

Example of data and interpreted targets from a 3-D GPR image .Blue is water, Magenta is electric and green is sewer.

11. R01-B Status • GPR Platform is Complete • EMI and Seismic platforms to be completed by October, 2011 • Field testing to begin as soon as all 3 platforms are completed. • Completion date is Summer 2012 Product: Platform prototypes field tested & ready for commercialization

12. Expanding The Locatable Zone For Underground Utilities (R01-C) • PI is Chris Ziolkowski, Gas Technology Institute • Goal Is Utilities Over 20-Ft. Deep • Technologies Include Seismic Reflection, Long-Range Smart Tags (RFID), Inertial Navigation Mapping, and Electromagnetic & Acoustic • Close Coordination with R01-B • Extensive Field Testing of Prototype

13. R01-C Current Status • Review of current and emerging technologies complete • Preliminary design of prototype system complete • Development of prototype system modules underway: • Seismic Reflection • Long-Range RFID Tags • Acoustic • Electromagnetic • Inertial Navigation • Field Testing to begin late fall, 2011 • Completion Date: Summer, 2012 Product: Field-Tested Prototypes ready for integration into commercial systems

14. R01-A: Modeling, Storage, Retrieval & Visualization of 3-D Utility Location Data How Do We: • Reduce project delays by keeping utility location data current throughout the project development process? • Reduce the necessity for repeating complete utility mapping for the next project in the same area? • Reduce excavation damage to utility lines during the construction phase?

15. R01-A: Modeling, Storage, Retrieval & Visualization of 3-D Utility Location Data • Best Practices for Modeling, Structuring, Storing, Retrieving & Utilizing 3-D Utility Location Data • PI is Alicia Farag, Gas Technology Institute • Developing A Prototype Data Model & System Architecture • 8-12 month Field Testing of Prototype System

16. R01-A Status • Preliminary data model and system architecture developed • Using utility location data provided by Virginia DOT for preliminary testing and validation of the data model • Once prototype data model and system architecture have been approved and validated, a pilot implementation operation/evaluation will be conducted • Completion Date: Summer, 2012

17. R01-A Products • High-Level, strategic model that can be implemented across the nation • 3-D utility data repository with the ability to accept and convert data from multiple sources and display and allow access in a controlled and secure manner • Protocols for use • Results from Pilot project • National Implementation Plan

18. Identification of Utility Conflicts & Solutions (R15-B) • Tool & Methodology to Facilitate The Identification and Resolution of Utility Conflicts To Be Used By Public Agency and Utility Professionals • Conflicts Include Interference of Utility Facilities with Highway design; Interference of Planned Utility Facilities with Existing Utilities, Non-Compliance of Utilities With Policies, Rules, Safety Regulations • Developed Utility Conflict Matrix, Procedures, & Training Course. • Project Completed, ready for implementation.

19. Utility Conflicts & Solutions Research Products: • Prototype 1: Compact, standalone UCM • Prototype 2: Utility conflict data model and database • Training Materials • Implementation Guidelines

20. Utility Conflicts & Solutions • UCMs are not simple 2-D table products • Compact, standalone UCM is an MS Excel spreadsheet • Utility conflict database is a formal data model (Erwin format) • UCM is one of many queries/reports possible

21. Prototype 1: Utility Conflict Matrix • UCM header: 8 data items • UCM body: 15 data items • MS Excel format • Includes drop-down lists

22. UCM Training Course • Lesson plan (6 lessons) • Presentation materials (PowerPoint) • Presenter notes • Participant handouts • Presentation handouts • Sample project plans • UCM templates • Companion CD • All training materials, including UCM • Prototype utility conflict database

23. Implementation Guidelines • Topics addressed: • Audience or “market” for the products • Impediments to successful implementation • Technical challenges • Economic and financial challenges • Stakeholder buy-in and consensus challenges • Policy challenges • Research product leaders (or “champions”) • Implementation plan • Performance measures

24. Great, but won’t these new tools be expensive and expensive to use? • FHWA study: $4.62 saved on overall project costs for every $1 spent on SUE geophysical techniques • Multi-Sensor platforms and improved deep-utility technologies more likely to be used by SUE firms than by DOTs
