Spring is the season for sprouting tower cranes, like this one for the Cook County Central Campus Health Center.

Thanks to a little birdie’s tip, we heard the nine-story, 282,000-square-foot Cook County Central Campus Health Center at the corner of Damen Avenue and Polk Street planted a tower crane stub this past week. The project was designed by Gensler, in collaboration with Forum Studios. Also joining the design/build team is Clayco, Inc. which is serving as the general contractor as well. They got some help from Stalworth Underground, who drove the sheeting for the foundation two weeks ago that you’ll see in the photos below.
