I bought a modular house with five lally columns bearing the center weight of the house. The plate that came with the lally column is not up to code and has to be replaced with a larger plate, any suggestions on how to this. ie: how to take the weight off and replace the plate.
Thanx

Hi Greg,
The first question that comes to me is why is it up to you to replace the plate, if it's a code violation by the manufacturer?
The second question is why now? Is there a failing in the structure or did someone just point out that your plate is not up to code?
The third question is are you absolutely sure that it's a code violation? Many times modular homes are built to a different code standard, but that doesn't make it a code violation.
Modular homes are not always the same as regular site built homes, with regards to the structural and may require special attention.
Have you discussed this with the manufacturer?

*I bought this house from a small setting company, I'm the general contractor and I'm responsible for the lally columns since I purchased them. All I was told was that I needed 4 inch concrete filled lally columns. The columns plate is only covering 2 of the 4 center trusses. The building inspector of our town failed the columns because all of the supports were not being carried. Thanx Greg
*Hi Greg,I'm not trying to pry too much into this matter, but for me to understand the extent of the problem can you tell me what you mean by, I'm the general contractor, do you mean this is your trade or are you asuming the role of the general on this little job of yours.It makes an awful difference in explaining a solution on the language used and the amount of detail required.Is this not simply a jacking and replacement of the plate situation or does something else have to be added?Sorry for the questions,Gabe
*S'cuse me for butting in. Please define a " lally column".
*Mark , to my knowledge it's just a pipe with plates on each end that supports a load bearing beam like in a basement . Their may be a broader definition . Chuck
*Gabe, I'm the general contractor for the sheebang, this was the first inspection by the building inspector, when the house was being set, I was told by the person I bought the house from to have the lally columns inside the foundation, the set people would place them. I left the plates that came with the columns. 4X4 inch plates. The area they support is 7 inches wide. Basically how does one jack up the house and replace the plate. This a 2900 sqf colonial. Thanx Greg
*A lally column is a 4 inch diameter 1/4 inch steel pipe filled with concrete used under a girder to support a load.
*OK Greg,You're going to have to use two jacks on each column. This way it doesn't matter if you have two beams intersecting, or 3 or 4. You may have to build a crib around the column but I think, as long as your careful, two 4 x 4's will do fine.Put a wide block at the top to distribute the weight of the beam or trusses onto the jacking post. I prefer to put the jacks at the top of the post, that way when I'm on a baker (small scaffold on wheels)I can do all the work by myself and when the pressure is off the column, substitute the plates and then release the pressure.Repeat at all the collumns until finished.Gabe
*mark< Just curious what do you blokes call them down your way?
*Related Question: Why are the columns filled with concrete and how important is it? I just replaced a section of bearing wall with a steel beam and columns, but the PE didn't specify that the columns be filled.Jerry
*Jerry,It's supposed to enable the lallys to retain enough support strength in case of a fire.
*Mark, for what it's worth, we pronounce "LALLY" to rhyme with "DOLLY".Of course, you may pronounce it "YLLAL" .... No, wait, ... that's "LALLY" backwards. I meant to say that you would want to pronounce it uspide-down.Doing what I can to help from the Northern half...Regards, Steve
