22 Transportation Operations Group Standardization of Utility Specifications and Unit Costs Project PD: Jeff Masek, CCA, Houston District RS: Cesar Quiroga, TTI

23 Transportation Operations Group 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

24 Transportation Operations Group 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
