  2. Utility Research Plan at TxDOT • Strategies to manage and integrate utility data • Procedures to optimize utility placement within ROW • Strategies to reduce utility relocation delays Transportation Operations Group

  3. Utility Research Plan at TxDOT • Strategies to manage and integrate utility data • Improve utility inventory practices • Automate utility data submittals • Improve utility conflict information management • Procedures to optimize utility placement within ROW • Planning tools to determine optimum utility placement • Strategies to reduce utility relocation delays • Innovative contracting practices • Optimize utility reimbursement practices Transportation Operations Group

  4. Research Projects Completed Active FY 06 – pending RMC approval Transportation Operations Group

  5. GIS-Based Inventory of UtilitiesProject 5-2110-01PD: Jesse Cooper, TxDOT Right of Way DivisionRS: Cesar Quiroga, TTI Transportation Operations Group

  6. Why is Research Important? • Before Relocation: • Quality of SUE deliverables • Utility conflict identification and resolution • During Relocation: • Quality of inspection • Post-Relocation: • Quality and completeness of as-builts Transportation Operations Group

  7. 5-2110-01 Objectives • Update inventory data model • Test updated model using sample project • Katy Freeway Reconstruction Project • Develop GIS database of relocated utilities • Develop positional accuracy and deliverable requirements for utility data submittals Transportation Operations Group

  14. Internet-Based Utility Permitting ProcessProject 5-2110-03PD: Joe Graff, TxDOT Maintenance DivisionRS: Cesar Quiroga, TTI Transportation Operations Group

  15. Why is Research Important? • 10,000+ utility permits per year • Paper and labor intensive • Incomplete documentation • Scaled schematic 20% • ROW line or centerline depiction 21% • Control section and mile point data 10% • Reference marker and offset data 5% • Variability in drawing standards • Utility maps not up-to-date • Institutional memory at TxDOT Transportation Operations Group

  16. System Implementation • Oracle database • Interactive ArcSDE/ArcIMS-based mapping • Secure 128-bit SSL encryption • PDF file conversion • Utility company user management • TxDOT user management Transportation Operations Group

  17. Workflow Diagram Permitting Pre-construction Construction Post-construction Utility inventory update Transportation Operations Group

  21. Current Activities • Testing and debugging • Interactive online help system • System management and reporting • System documentation • Training materials Transportation Operations Group

  22. Standardization of Utility Specifications and Unit CostsProject 0-4998PD: Jeff Masek, CCA, Houston DistrictRS: Cesar Quiroga, TTI Transportation Operations Group

  23. Why is Research Important? • Utility Accommodation Rules (UAR) • Cover basic requirements • No standard specs for utility installations • Many special specs and provisions • Utility relocation costs • Utility relocation cost estimates • No standardized cost data submittal • Difficult to assess validity of cost data Transportation Operations Group

  24. 0-4998 Objectives • Review specifications for utility installations • Review utility relocation cost documentation • Develop recommendations for specifications and changes to the UAR • Develop methodology for estimating costs Transportation Operations Group

  25. Cost Estimation Approaches Cost Categories Transportation Operations Group

  26. Category and Activity Variability • Names • Level of detail • 9 subcategories within overhead … • 3 subcategories within materials and supplies … • Design, Construction, Removal • Inconsistent use • Activities treated as categories • Categories treated as activities Transportation Operations Group

  29. Integration of Utility Data in the Project Development ProcessProject 0-5475FY 06 – pending RMC approvalPD: Gary Ray, Houston District Transportation Operations Group

  30. Why is Research Important? • Utility relocation on critical path • Earlier utility depiction for design • Absence of utility conflict data standard • Multiple data management systems • Incompatibilities • Data format and content limitations • Data access limitations • Delays, added project costs, liabilities Transportation Operations Group
