Phase Two tower crane permit issued as 220 North Ada reaches fourth floor
One month after receiving a permit from the City of Chicago to complete construction, 220 North Ada progress has reached the underside of the fourth level. And on July 8, a permit for Phase 2 was issued for the project’s tower crane. That means once the concrete core has grown a little higher, concrete contractor Adjustable Concrete and GC Clayco will tie the crane into the core and insert a few crane sections into the “tower” segment for sufficient height.
