Task

Cross Bore Inspection After Fiber Installation

PROBLEM

  • The client, a large telecommunications firm, was Installing fiber in Fremont, California.
  • The City of Fremont requires all contractors to conduct closed-circuit television (CCTV) Inspections of its sewer lines before and after completing any utility installation projects to mitigate the risk of cross bores (inadvertent intersections of utilities.
  • The City of Fremont is the fourth-largest city in the San Francisco Bay Area at 88.46 square miles.
  • The subcontractor our client employed to conduct the CCTV inspection of the cites utilities prior to fiber installation pulled out of the job before the post-installation inspections could be completed due to the size and complexity of the project.

Solution

  • We utilized our VPI services to inspect the city's sewer system for cross bores.
  • GPRS uses an arsenal of state-of-the-art video pipe inspection tools to visualize wastewater infrastructure, including lateral launch cameras, robotic CCTV crawlers, and push cameras.
  • We identified ten cross bores within the city's system.

Benefits

  • Safety: By locating these cross bores, GPRS ensured that our client and the City of Fremont could make the necessary repairs to guarantee the safety of the community.
  • On Time: Our rapid response ensured that our client was able to remain on schedule even after the original subcontractor pulled out of the job.
  • Reputation: By locating these cross bores, we ensured that our client could complete the requirements set forth in their contract with the City of Fremont. And because the cross bores were repaired immediately after they were located, there were no service interruptions for city residents.
