PRIVATE UTILITY LOCATING SERVICES- ST. LOUIS, MO
We make a point to mark every line and sub-structures precisely for easy identification. Unfortunately, there is no uniformity when it comes to the organization of patterns used to install underground cable and piping. That’s why we don’t play the guessing game and make sure everything is labeled appropriately. Excavate with confidence.
TSI is a BICSI corporate member with six in-house Registered Communication Distribution Designers (RCDD). Our field staff are factory trained and certified by the equipment manufacturers we use and follow all industry best practices for low-voltage systems installations.
