To enable cable routing between the conduits, use pull pits to join conduits between duct banks. Begin by placing the pull pit, found in Equipment, and then routing the duct banks up to the pull pit. Within the pull pit, connect conduit end features belonging to different duct banks with zero spec cableway (CWS-0). The zero spec cableway ensures continuity for cables to pass through. In addition, using the Auto Connect command to create these connecting cableways simplifies the process.
The following illustration is an example of a pull pit; this is just one option.
