^I've been wondering about that too. I was looking at the ground floor plan for it yesterday, trying to figure out how the parking traffic and basement loading and unloading patterns would work. It's a full service hotel and will need lots of deliveries, etc.
What is notable is that the full ramp down to the basement has been more than half covered up with the flat section back out to Bay. If this is a change in design, then it happened well after construction was underway. It also causes a lot of wasted underground space, which this site cannot afford.
Last night it occurred to me that this could just be a "temporary" feature to allow concrete and service trucks better access to the site until construction is completed. It is a very small site, after all, and the access to it is restricted in the extreme. After construction is completed, the full ramp down to the basement would be re-exposed and the upstairs parking ramp expanded. Anyone have a different thought?
