Hi,
The Bottom plate is gone and I am having troubling lifting it to
slip a new 4x2 into place,see
http://img170.imageshack.us/my.php?...uprightsjk6.jpg

I was able to get one end or about the first 12 feet but as I get to the
middle it is getting more and more heavy.
Main problem is lifting the uprights,can lift the floor no problems,but
those uprights are jammed hard down with lots of weight.

The building is about 30m long by about 8-9m wide,the walls are tied at
the roof line with steel bars to stop the weight of the roof pushing the
walls out,along with a network of wooden truss sections etc.

Any Ideas on how to lift these?

TIA

could try fastening a ledger to the studs (uprights as you call them)
and jacking on that. I've moved garages like that, don't know if it
would work on a heavier building.

Rent a bunch of steel I-beams, the renter should be able to tell you what
size you need. Dig out enough so that you can get the I-beams in place
under the supporting walls. Jack up the I-beams using the hydraulic jacks,
or even a good car/truck jack. Work through the jacks one at a time
lifting maybe a 15mm, then on to the next jack. Once the house is as high
as you need it to go, use railway ties or other braces to hold up the
I-beams while you do your work. Don't work under the jacks alone - if one
of them gives, you may be in for some trouble.

Arhh,Great idea,I am looking at about 10ton of weight however on each of
these studs once lifted a fraction I think,well 5 ton jacks are giving
it up if you get me.
A ledger I have seen done before on houses years ago,then using 22ton
long truck jacks to lift it off the ledger.
I am guessing that putting a ledger on these 4x2 studs may almost spilt
them when weight is transfered to a couple of them in series.
Making the ledger is another thing altogether,it would need to be a good
bit of steel to take 10 ton.

Its the best idea yet,possibly the only.
Thanks again.

Is this a wood framed building?

2x4 studs? Wood roof? Trusses? Steel bar joists? One story or
two?
Is this a wood framed floor? Concrete slab? Is the floor in
reasonable condition?

Can you install a 4x4 or something similar that pushes on all the
floor joists close to the outside wall with a 2x XX as a mud sill?
A 20 ton bottle jack every four feet or so should be able to pick
almost anything up with good control. How far are trying to raise
this?

Yes almost all wood, walls are 3.2m high with 4x2 studs

Yes, wood roof has shingles then roofing iron ontop to add to the
weight,There is a total of 3 steel bar joists running at the top of the
walls,
One story high

Yes wood floor boards through out,in execlent condition.

It could be possible,however the weight is great,also as it sits on the
old 4x2 mud sill it has become undulated so is not quiet a straight push
to get the new one in.

I got the first part in by lifting about 1/8 in then bashing the new
mudsill in with a sledge hammer at the same time pushing the old one out
underneath the building,It was messy and I split alot og the bottoms of
the wall studs

The problem possed is one to lift the studs as they bear more than 5 ton
each,how to attach to the studs,?
1 inch would be the maximum it needs to be lifted,to replace the mud sill.
