Installing Lally Columns

osborneconst

I am a new builder and I find a lot of useful info on this site. I just got my first job, a small house, only 912 sq.ft. The plan has changed some and now involves a steel beam and 1 lally column. I need some help with the proper way to install lally column. The column will sit on a large concrete pier in the basement. Do I need to pour the pier and then install the lally column or install the lally column when I pour the pier. There will be a 4" floor poured, and I dont want the column and plate to stick up out of the floor. How do you guys do it.
Thanks for the help

When the mason pours the footers, he should pour a pad for the column. Have the beam set and the framers will set the column in place and level it up. Then you can pour the floor later.

Here In NJ and probably most everywhere else, that column has to sit on its own footing. Per Rhino when the footings are dug for everything else have em set one for your column,have framers get the steel header set on temps, pour footings when set, put your CEMENT FILLED column in, pour floor.

The column does have its own concrete pier. The basement will be superior walls(no concrete footing) as most of you probably know. I just didnt know if I needed to set the column as the pier and the floor were being poured or pour the pier, then set the column as the floor was poured. Thanks for your replies.

Mark; If I understand correctly, you already have a footing in place, then I would set that column before you pour the floor. This way it cannot be knocked out from under the header. Here that is how we have to do it, also as I mentioned cannot use jacking columns, solid filled. I fairness I have heard a few times that if jacking are used you MUST weld em once set to height, however that I cannot verify, with solid fill no questions left to answer

So the pier is dug, but not filled with concrete yet? Pour the pier first. Superior has precast piers that they supply with their walls. I saw them use them on a house near me this summer. Personally after seeing the precast pier, I would pour my own.

If it is superior walls, then they should provide you with a square pre-poured pad. The framer should dig up the stone and place the pad, then set the column under the beam and level up the beam. Then pour as normal.

Just curious as to why the framer should dig up the stone and place the pads?

Around here they pour the piers at the same time as the footings. They then put a small piece of 12" sonotube over the pier. Then they pour the floor. When the framers get there we set our beams on temps and mesure from pier to beam and order posts. Place the posts and concrete guys add concrete around base to match with the floor later.

The one-piece lally columns that have only 4 inches of adjustment are code in NY (and most other states i know of)-but the ones that are two tubes and adjustable are not as you say.

On retrofits, I cut the lallys on site to whatever they need to be. Mark the cut line, cut the steel with a grinder and then lop off the waste with a hammer blow. The concrete usually breaks really cleanly.

Don't get me wrong, it's a pain in the neck to cut a lally column, but it's not hard to do.
