No, but its a lot more work/expensive to do it without. Without a crane you'd need more street lane closures to accommodate the pump trucks, and mobile cranes for doing work that you need a crane for (such as lifting forms) which the city charges for. Then you have to pay for the operators of those equipment, and use of that equipment itself. Tower cranes could work out to be fairly cheap in comparison, which is why we've been seeing more of them on smaller scale projects than we used to.
So any proximity issue could impact the timeline as if they may need to change the plans for how the building is constructed to meet whatever requirements they've been forced to deal with from the adjacent site. That or they could just wait to start until a point so that by the time excavation is completed that the other crane may have been taken down.
