This was a big week for construction progress at One Delisle. On Friday, we poured the first bit of our raft slab foundation on the west side of the site. Big concrete pours like this usually take all day and this case was no different. The team was there late into the evening. And then today, the first of our two tower cranes was erected:

The crane going up is always a big milestone because, in my mind, it signals the start of "real" construction. What I mean by this is that all of the stuff that comes before -- demolition, shoring, and excavation -- is really just to get the site ready for building. Well, now we're ready, and that means we're about to go vertical.
A big thanks to the team for working around the clock over the last few days.
Matthew Slutsky (formerly of BuzzBuzzHome fame and now of Livabl fame) recently invited me on his podcast to talk about some of our current and upcoming condominium projects, as well as about the market in general.
Despite my best attempts, I only briefly talk about NFTs and crypto (in the context of our One Delisle project). So if any of you are sick of hearing that from me, the episode should be overall fairly tolerable.
To have a listen, click here. It's about 30 minutes.
Thanks again for having me, Matthew.

This past week we poured the first bit of concrete in the giant rat slab foundation (or mat foundation) that sits, or will sit, at the bottom of One Delisle. At its deepest point, below the building's core, it will be over 4m tall. Meaning, the area occupied by the gentlemen in the above photo will be fully covered in concrete when it's complete. Note the height of the rebar in the middle of the photo. This picture doesn't even do it justice, though. You need to be on site and down in the bottom of the hole to really feel it. There's a lot of bar, and it's going to be very deep.
In our case, this raft slab foundation will, as it sounds, serve as the building's foundation. This is what the tower will rest on. However, raft slabs can also serve the function of withstanding hydrostatic pressures from below (groundwater). That is the case with the raft slab foundation at Junction House given that we have a watertight "bathtub" design for the underground. However, that's not the case here at One Delisle, as the groundwater levels aren't as high and this will not be a "bathtubbed" underground. So the job of this giant slab is as a mat foundation.
