Existing cables

A model which contains existing utility and supply cabling. Allows for a survey of the existing cabling before construction and determines the location of cabling that may require relocation during the construction phase.

During the design phase, a 3D model of the existing utility and supply cabling can be useful in aiding collision detection, thus avoiding collision between pre-existing and designed elements.

General requirements for 3D modelling of existing cabling are set out in the CAD manual Appendix, section 4.2.1.5.
