The reason I brought it up is, who can live in a sleeve and does it have to be "conduit"? Typical situation, the GC put a 4" PVC plumbing or DWV pipe under the driveway. The irrigation guy shot a 1" black poly pipe in there, The landscape guy put his Malibu zip lead in there, the TelCo and CableCo went through and the electrician needs to get a 12/2 UF across the driveway. Can he go through it? Joe T an I used to always disagree about this.
