^^I thought it was the owner of the little building that's yellow in your image above who wouldn't sell but could have been the white "not part of project" building. 88 First, of course, is probably landmarked and couldn't be torn down.
Came across this for people who are really bothered by the elevator cores:
Quote:
The elevator cores would be pulled to the rear of the site, allowing for large, column-free floors and a structure that is 25 percent lighter than the building would be with conventional construction methods.

The column-free floors, especially, are desirable to many office tenants.
Also came across this shadow simulation which explains the height limittion at that location:
Quote:
Once complete, Oceanwide's towers will cast new shadows on four downtown parks: Union Square, Portsmouth Square and St. Mary’s Square in Chinatown, and Justin Herman Plaza on the Embarcadero.
Due to the 1984 Sunlight Ordinance, both the Rec and Parks Commission and Planning Commission had to decide whether the new shadows would have an adverse effect on those spaces. Both commissions ultimately decided they would not . . . .

No shaddow adverse effects at permitted heights, but if higher?
