Neither shall the existence of such Documents preclude their voluntary use by non-TIA members, either domestically or internationally. TIA DOCUMENTS TIA Documents contain information deemed to be of technical value to the indus

Such deviations, caused by foreign underground structures or geological obstructions, whether planned in advance or uncovered during the cable installation should be recorded when: - horizontal deviations made from the facilitys route extend beyond the tolerance zone specified in the applicable
9、 damage prevention law or, where none is specified, by an equivalent 450-mm (1 8-in.) tolerance zone from either side of the facility (see figures 1 and 2 ) . - any vertical deviation that results in a depth less than the design minimum, or a depth exceeding the design minimum by 300 mm (12 in.) or
10、more. The measurements giving the location and extent of such deviations should be noted either when the route is planned, or reported at the time the obstruction is discovered during installation of the facility.

Calling the one-call bureau is intended to be the means of notifying all participating facility owners to locate and mark their facilities in the vicinity of the proposed work to prevent facility damage by the excavator. A onecal
