River Point Shows Growth Potential in Both Height and Tunnel Capacity

Work is moving along very quickly to turn a weed-choked embankment, a gravel parking lot, and a bouquet of train tracks into a 1½-acre riverside park and a sexy, 650-foot-tall, curvy office tower named River Point.

Houston-based Hines, and Montréal-based Ivanhoé-Cambridge still have a long way to go to meet their goal of opening the tower in the beginning of 2016, so construction crews are very busy.

The first big project is encapsulating the Amtrak lines that run into Chicago Union Station in a tunnel with a park on top, while still allowing Amtrak and Metra trains to use the rails normally.

It’s already possible to see the bones of this beast being planted — rebar cages sprout from the ground to the east and west of the tracks, and the access road has been rebuilt parallel to the easternmost track.

On the other side of the tracks, we see the first evidence of the 45-story tower’s foundation. There are six huge rebar cages protruding from a concrete mat. I don’t know much about foundations, so perhaps someone else can look at the picture and explain what’s happening. But comparing the location of these cages with the diagrams of the building’s structure provided to the City of Chicago by Pickard Chilton, it appears this will be a mechanical room under the lobby.

Interestingly, according to a letter from the Chicago Department of Housing and Urban Development dated October 3, 2012, the developers of River Point can actually go taller than 45 stories if they want to.

According to the HUD letter, Hines and Ivanhoe can throw on another four stories (49 total) if they want to, without asking anyone for permission, as long as the building stays under 702 feet tall. Years ago, the tower was originally approved for 53 stories and 736 feet, so this isn’t exactly controversial.

Pickard Chilton has put together a drawing showing the building with an extension to 49 stories and 700 feet. Perhaps if Hines can put together enough leases before construction gets too far along, the building may reach higher than we thought.

It has been designed, and the supporting columns placed, so that yet another rail line can be crammed down its throat. Looking at the tunnel diagrams, it seems like an interesting piece of macrame, but this is Chicago — we’ve engineered bigger, crazier things than that before.

  1. The “mucky area” beyond the new seawall is only mucky because it used to be part of the Chicago River. It was probably necessary to build in the river to sufficiently anchor the platform over the RR tracks (especially since one more track will be added to the 4 existing ones). River Point will be very pretty and quite a structure when completed.
