They move those dollies very slowly, you wouldn't want them gaining much momentum! I'm sorry we weren't able to wait to watched the entire process of its arrival in the right bay, and then an install… but we did see how early ones were set up:That looks complicated and dangerous.
Thanks for doing this! This is amazing to see.They move those dollies very slowly, you wouldn't want them gaining much momentum! I'm sorry we weren't able to wait to watched the entire process of its arrival in the right bay, and then an install… but we did see how early ones were set up:
Here you can see where the new trusses (rust coloured) are being attached to the building's original steel columns. Since they're going to be digging out four more underground levels than what's there now (like at Union Station but twice as deep), they've got to transfer the loads from the columns to the outside of the building where a new concrete grade beam has been placed. (More on it further down.)

…onto the grade beam. First thing that went in at the site was a concrete beam with columns below it into the earth to take the load from the interior. Gradually, the existing building is will rest on it.

When I get time to go through more pics, we'll go downstairs next.
