This pic is a week or so old but they've poured concrete about halfway to the left of that dirt field and are continuing to do so. They've also filled in the former pullover lane for old Convention Center (under the trees by Market Street) with mulch and plants and redid the curbline. It doesn't seem like the work to be done for an apartment, maybe this lot will be temporarily opened up? Or my wishful thinking, they're abandoning the apartment and extending the park in some way. Also the entrance to Civic at Market and Alamo is closed off and being redone, tearing up the curb and sidewalk.
