The next few weeks could get interesting with the possibility of the start of truss instillation.

Yeah, after they jump the core to the next floor (which should be any day now, they are probably pouring the current floor today or tomorrow) I'd imagine they will break out those giant knuckle joints we saw being fabricated a while back. The steel seems to be following extremely closely behind the rising forms so far.

I want to say that I saw a truss connection on site at the northeast corner at plaza level. I was on the boat and snapped a picture.

^ indeed from the construction cam looks like they have loaded up the platform with a few layers of wood for weight distribution. There a few large chunks-o-steel out there right now

Are they putting on a steel joint on the core right now? Hard to tell from the cam.

Edit: It was just an odd viewing angle

I hope the ground level(s) gets completed soon so it can start to rise with more concerted effort.

Floating Rig Tackles Tricky Chicago Site
06/23/2015
By Jim Parsons

A bright red Manitowoc 888 ring-type crane sitting on a barge in the Chicago River is playing a critical role in the construction of 150 North Riverside tower, whose site is sandwiched on a narrow, 380-ft-long spit of land between the river and a rail corridor.

For general contractor Clark Construction Group, Chicago, and subcontractor Chicago Steel Construction LLC, Merrillville, Ind., the challenge was to construct the foundation and lower floors while installing nearly 200 bulb-tee girders, weighing as much as 90,000 lb, to support the tower's new pedestrian plaza.

Due to its small footprint on the ground, the perimeter skin of the 1.2-million-sq-ft office building widens from its compact lower-floor footprint, ultimately rising to 54 stories upon completion in early 2017. Hemmed in by two elevated viaducts and an adjacent building, the site was simply too crowded to support a land-based crane with a reasonable reach.

"We realized we had the river at our doorstep," says Chris Phares, Clark project executive. "So, why not use it?"
