^ ... and correct me if I'm wrong, but I don't think Chicago's water table is particularly high unless you're east of JBDLSD

Guessing 909 N. Franklin...

205 W. Oak & 312 W. Walton are projected to start in 2024, but we'll see what next year brings.

Well, it is more expensive, that's a fact. I'd like more underground parking too or at least garages lined with linear active space.

Not just cost but time. If you have to dig down before you can go up, that adds months (or years) to the timeline. Time is money and risk - if the rental market is good now, you don't want to be delivering new apartments 30 months from now when there could be a recession.

This is partly why Chicago engineers developed the top-down construction method, so you can build vertically at the same time you're digging down. Of course, that approach adds up-front cost with expensive secant walls etc, and works best on large sites.

For North Union it looks like there was a package deal - they moved at lightning speed on 920 which has a parking podium, and they will deliver those units relatively soon. While that's going on, they can build 868 with underground parking using the cheaper but slower bottom-up method. That way they stagger the delivery of new apartments which hedges the risk nicely - there probably won't be recessionary conditions for both building deliveries, so at least one of the two towers will start off with strong financial returns.

Does anyone know why parking is above ground on the north building and underground on the south one? Doesn't make sense to me.

Could be utility relocation issues.

My guess is they wanted to get the first building to market ASAP. Then it becomes ok for the next building to have the extra construction time required for underground parking.
