We have a new construction and I am curious as to what the metal rods are that hang beside the i-beam at the basement level (at the notch in the foundation) and that continue up to the next floor where there is another i-beam. Similar to this post on the details

Ours has what look slike a super strong L-bracket that is attached to the foundation where the steel i-beam sits... from this, there is what looks like two metal rods that continue upwards to the next story I-beam. I assume these are there to help place the i-beam, or something. but they are not tight as they can be wiggled by hand and the play is a couple inches both direction.

The home is a new build 2008 ontario rowhouse which is 3 stories plus basement.

Any ideas? Should they be tight or loose?
