Re: How Can I Do This Without Getting Squished?


I'd probably add strapping the upper joists to the upper beam, near the posts, so that when you put in the temp walls (small ones only near the posts?) the joists lift the beam and take the weight off the posts. Without live load there shouldn't be a problem with that.

I don't think there's any way around putting beams under the bottom deck and lifting. I'd get a house mover to do it. All in a day's work for them. Expensive, but a fraction of the cost of re-building.

As everyone else says, I'd sure be careful about the connection to the house. Lifting the outboard end a couple inches could easily be enough to strip the wood around a lag screw - all you need to do is pull a lag through the ledger 1 thread's distance, and it's done. That seems more risky to me than any of the lifting/shoring stuff.

With all the engineering and house mover/lifter costs, does it make this project more appealing to demo and rebuild from the ground up?

But are the piers sized properly for that load? Doubtful. If they couldn't get the beam spans right I sure as hell ain't going to trust their piers.

Maybe not on this behemoth, though.
Not sure why this would scare you. Obviously you need to analyze the house connection and provide plenty of cables or braces. We do quote a few structural repairs. Being creative has really helped on more than one occasion.

Maybe frightening was the wrong word.

Ingenious or outside the box then.

I knew what you meant.
If you were truly frightened, you would've walked and not even posted.

I've seen your work and I'm betting you already know the solution but wishing there was an easier way that you haven't thought of.

Nope

Re: How Can I Do This Without Getting Squished?


Didn't read through all the replies, so forgive me if this has already been offered.

I would bolt a piece of heavy steel angle through the lower part of the 6x6 posts and lift the weight off of the beam with hydraulic jacks from the footing below.

Once lifted to desired height, prop down from the second floor beam to insure that there is a backup to the jacks. Remove jacks and post down to footing from angle.

Now support first floor joists as necessary and remove/replace beam.

Re: How Can I Do This Without Getting Squished?


here's my input

Do you have tools and equipment for lifting structure
at least 7 bottle or screw jacks.

#1 check structural connections.Safety 1st, while underneath this bone crusher
#2 dig all new footings for proper spacing.
#3 temporary wall between 1st & 2nd deck
#4 jack & support deck away from all footing locations
block & support for safety & structural integrity
#5 remove beam and replace existing footings

#6 new post , beams , & beam to beam post for 2nd floor.

DONE BY NOON. GOOD LUCK, PRICE HIGH.

Re: How Can I Do This Without Getting Squished?


Nobody here work with shoring towers? Might want/have to pour some temp support pads. Maybe some cribbing would work. Definitely may want a engineer's plan for the shoring.

Have used these systems to form and pour cast in place bridge beams. Using these would make that child's play

Shoring towers for a 10 x 50 deck ?

There's only six bearing points to ground, (it looks like)

Just, think it through, it's not that much weight, It's a deck......

I know the cost of erecting probably 2 towers most likely one. Would trump pouring pads and building temp walls. What you don't know how to build shore towers? Build on cribbing 2-3 man hours max. Maybe you need a background check?

If that question is to me.

cribbing, Enough for 4 or 5 x 9 ft tall. how much is that $$$$

if I was doing it.
The job is done already, w/o shoring towers.

But, that's just stupid me , ...

Crib the shores, use the screws on the shore legs to support and raise the structure. I am done before you.
