Missing anchor rods in new Ottawa bridge? 1

[canadiancastor]

Friend sent me this one, not sure what to make of it. Anyone know what kind of product this might be? Or are the anchor rods cut flush to the top of the nuts? I believe this is a new pedestrian bridge in Ottawa, Canada.

looks like elocone nuts:

They aren't cheap, but a great solution for short projection on anchor rods.

How do you enlarge the holes in the base plate if needed?

 

[BridgeSmith]

With a proper template to align the anchor rods, enlarging the the holes in the base plate isn't necessary. Enlarging the holes in something like that wouldn't typically be allowed, anyway.

How do you enlarge the holes in the base plate if needed?

Looking at their documentation, all of their extended nuts have a smaller OD on the extension than the "Recommended Maximum Sizes for Anchor-Rod Holes in Base Plates" per AISC. So if you're way off on your placement or you have steel-steel hole sizes in your base plates (lookin' at you, MBS industry...), it may not be doable, but in most cases it probably would.

On an unrelated note, surely those tiny stiffeners are doing bugger-all?
