Google Fiber

Scope

Comprehensive analysis into the existing subsurface in preparation for the installation of Google’s fiber optic cable network. Overall data shows that Vosburg Welsh prevented at least 200 probable utility strikes across over 975,000 LF of trench line.

Project Description

Client was conducting micro-trenching operations in Austin, Texas to install Google’s fiber optic cable network. Micro-trenching involves cutting the existing asphalt/concrete down to approximately 18”-36” in depth with a large circular saw. Working together with public utilities and their location crews, Vosburg Welsh designed a comprehensive analysis into the existing subsurface. Ground Penetrating Radar was used to identify utilities missed by the one-call system – as well as to confirm the precise location of utilities marked by the public utility locators. This was particularly effective for the existing City water system, as nearly all of the service line locations were not available within existing records. Overall data shows that Vosburg Welsh prevented at least 200 probable utility strikes across over 975,000 LF of trench line.
