    There are 3-wire and 4-wire ways to wire three-way switches, depending on the juxtapositions of the switches, the supply, and the load.

    If it was specified to be an all conduit/wire job with J-boxes with whips to fixtures, Then the travelers, hot, neutral, switchleg could be routed through the conduit from one switch location to the other.
