I-64 Widening & High Rise Bridge Design-Build

The project is a large design-build project to improve major traffic issues in Hampton Roads by widening I-64 and replace the existing High Rise Bridge in Chesapeake, VA for Virginia DOT. The cost is estimated at more than $450 million and is one of the largest VDOT projects in the Hampton Roads region.

T2 Utility Engineers began working with the JV team Granite/Parsons/Corman (GPC) during the bidding phase to identify potential utility conflicts along the entire project corridor. We also provided Subsurface Utility Engineering (SUE) services throughout the project corridor. Conflicts with public and private utilities were found, both above-ground and underground. Using the information provided by VDOT, T2ue engineers assisted with the development of the Utility Conflict matrix which was used by Granite/Parsons/Corman throughout the project to support the efficient construction.

All expenses related to utility relocations were the responsibility of the JV team, rather than the utility owners, because of the FHWA and VDOT requirements; an interstate within a city. As a result, it was important to include accurate relocation cost estimates in the Utility Conflict matrix and ways to mitigate the utility risk to the project. T2ue provided Utility Coordination services on this project for the private utilities only. Coordination of the public utilities was handled by the JV team.

T2ue facilitated the submission of the private utility relocation plans, scheduling of any required relocations, and coordination with the GPC team as well as VDOT. Private relocations were in accordance with VDOT and FHWA standards and requirements. The utility companies included; Dominion Energy, Verizon of Virginia, Verizon South, Segra (formerly Lumos), Columbia Gas Company, as well as two (2) cell towers. T2ue also provided Subsurface Utility Engineering services which included 82,550 LF of utility designation and more than 90 test holes to verify the accurate horizontal and vertical location of specific utilities for the project design team.
