"... When adjusting, installing or otherwise working with non-metallic conduits for underground utilities, the Contractor shall install on the conduit a metallic tape or provide other suitable means whereby the installation can be relocated by electronic detection devices."
"... When installing non-metallic water pipe, the Contractor shall install a metallic tape or locating wire on the pipe or provide other suitable means approved by the Engineer to allow for location by electronic detection devices. ..."
"... When installing non-metallic sewer force main pipe, the Contractor shall install a metallic tape on the pipe or provide other suitable means to allow for location by electronic detection devices. ..."
"... When installing non-metallic gas pipe, the Contractor shall install a detectable tape or locating wire on the pipe or provide other suitable means approved by the Engineer to allow for location by electronic detection devices. ..."
"... 7. Installation of Warning Tape.
For Type 1 “Open Trench” Conduit Installations, the Contractor shall place the warning tape within the same ground cut (ditch) as the conduit and locate tone wire as shown on the Plans. Once the conduit and locate tone wire are placed, the cut/ditch shall then be backfilled up to a point no more than 12 inches {305 mm} below grade and at a maximum of 6 inches {152 mm} below grade where the Contractor shall then apply on continuous, unbroken length of the warning tape between the CommBoxes. The cut/ditch shall be completely filled in and prepared to its original state or as specified by the Engineer.
For Type 5 “Directional Bore” Conduit Installations, the warning tape shall not be required unless otherwise indicated on the Plans."
"... Marking tape shall be provided for all PVC force mains to allow for locating by location equipment."
"Warning Tape shall consist of an underground/buried tape marking the locations of conduits containing fiber optic cables and/or electrical conductors as indicated on the Plans.
Warning tape shall be 3 inch {7.6 cm} wide, elastic PVC, tear resistant, corrosion resistant and durable to extreme weather conditions. The color of the tape shall be orange with “ALDOT FIBER OPTIC CABLE - CALL ALDOT [insert phone number to be provided by the TSMO Engineer]” printed every 3 feet {0.9 meter} in black letters, unless otherwise noted on the Plans.
