Guide for Abbreviation Use


Follow these guidelines when placing abbreviations in the field:

  • Place the Company Identifier at the top or at the left of the abbreviations.
  • Place the abbreviations in the following order: Company Identifier / Facility Identifier / Underground Construction Descriptions / Infrastructure Material

Example: TELCO/TEL/FO/PLA indicates that TELCO has a telecommunication fiber optic line in a single plastic conduit. The use of the abbreviation /TEL is not necessary,because the orange marking would indicate that the facility was a communication line; but its use is optional.

  • To omit one or more of the abbreviation types, use the order described above but omit the slash and abbreviation that does not apply.

Example: to omit /TEL), the result would be TELCO/FO/PLA.
