Bolt holes do not line up exactly d
Bolt holes do not line up exactly d
(OP)
Bolt holes do not line up exactly during erection and contractor is sometimes just enlarging the hole to be able to insert a bolt. They do not weld closed the unnecessary part of the hole, so you see a bolt in a large hole - they use a correct size of the washer of course and the bolt head is supported by the structural steel from three sides (only one side falls resting on the washer only). Is this a point of concern?

If the erector is using a torch to modify the hole sizes, you can have many more problems.

FWIW, i wouldn't fill the hole with weld filler; i'd be more worried about the hole finish.

So test your finish product before having it used by the owner and think about reducing its loading and life span.
