This is a photo of Junction House that I took this morning after our weekly construction meeting. The team is currently preparing for the first concrete pour of level 4 (each floor has been split up into three pours). We're now flying our forms, which means that we're able to move a lot faster. This is the exciting part of a new build mid-rise like Junction House. The underground garage part is like watching paint dry.

We're scheduled to be topped out by this summer, so expect some gratuitous view photos on the socials.

Many of you are probably aware of the 58-storey Millennium Tower in San Francisco which is estimated to have sunk about 17 inches and to have tilted about 14 inches to the west since it was built.

Well today it was announced that they may have a fix. Here is what is apparently being proposed as a retrofit (image from SFGate):

The tower was originally built on top of a 10 foot thick raft or mat foundation, which was then supported by concrete piles that went down 60-90 feet into soft clay. Notably, the piles didn’t reach bedrock.

The proposed solution involves drilling 275-300 new micropiles into the bedrock below. But here’s where things get really interesting: The plan is to stabilize the west side of the building first and allow the east side of the building to continue sinking. In theory, this will give the building an opportunity to level out before they fully stabilize it. 

According to SFGate, the entire retrofit is expected to take anywhere from 2 to 5 years, and cost somewhere in the range of $200 to $500 million. The original tower cost $350 million to build. (I’m assuming that’s just the hard cost number.)
