More from 525 Golden Gate:
They appear to be nearly done driving I-beams around the perimeter. I'm sure they will then drop timbers between them to form the retaining wall for the foundation as they dig it.
This brings up a question. I have seen or heard of buildings being stopped at all stages of construction, due to unforeseen circumstances, including after the foundation has been dug but before any actual construction was begun, but I am not aware of any building digging the foundation without the intention of proceeding to construction at the time that was done. In other words, is there any reason to think this work doesn't mean the city has every intention of proceeding with construction at this point it time? Would they do this if the funding was still in doubt? I thought they planned to stop after demolition of the old building if that were the case.
Anyway, here are today's pics:
Note the line of I-beams along the Golden Gate side of the foundation perimeter--leading to the pile driver which still has a few to do
The site from midblock on Polk
Note the finished I-beam perimeter along the alley side of the site
Ready to dig
