ONE CALL SERVICES - One Call Systems, Inc. (OCS) provides the most complete solution to damage prevention in the industry.    OCS operates one-call centers across the United States and has provided one-call services continuously since 1974.  All of these one-call centers operate on OCS’ software and Stratus FAULT TOLERANT hardware.   This system is integrated with OCS designed MapInfo based mapping modules supplying the smallest possible notification area including TRSQ, “mini” grids and/or Polygons.  Any combination of these methods can be utilized to fit what the user desires.

SCREENING SERVICES - One Call screening software, Screen 'N Go!, is the most powerful and versatile screening solution for utilities.  We can "screen" one-call tickets for you. For the tickets that are "cleared", we will notify the contractor directly (you don't have to do anything). For the tickets that need a mark-out, we'll contact (via voice, fax, modem, or Internet) either you or the locating company, depending on who is doing the mark-out. And since we are a 24/7 operation, we can handle "Emergency" tickets very quickly.
