Over and under garage project

[Virago9577]

Well,

Check out my 28 x 14 x 10 garage.....Once complete it will be suspended 10' off the lower foundation floor. The garage will be repainted crisp white and the cement will be poured into a galvanized steel tray supported by four 8" ibeams that span the 14 foot width. The cement will be 32mpa and we'll install pex for radiant heat. The project should be complete by end of September. Any and all comments and suggestions are welcome. The first pic is of the excavator with hoe ram breaking up the rock under the garage.

Are you having a garage above and below or a garage above the basement? Looking forward to pics but I am confused. that doesn't take too much to do to me though

Sounds like a fun build to watch!

Yay. Hydraulic fun going on there. And a nice bit o' steel. I can't wait to see how that comes out.

I thought I had a big job preparing for my shop. At least I don't have rock to excavate. That's some tough work.

Hey guys, The truth is we are on a lake and we can't increase out footprint so when we decided to put in a full basement to replace the crawl space we first excavated 80 tandem loads of rock and dirt. We also excavated under the garage and have since placed 4 x 8" ibeams across the garage (14 ' x 28') and will then fill a 28 x 14 galvanized steel tray with cement 4" deep. Under the new floor will be a shop/basement. My better half has already said no ATV's or bikes in the basement.....so enuff said for now...but who knows?

So far it's come out really well. The beams will make the whole structure like the rock of Gibraltor. Speaking of rock...here's a pic of a few that we elected to save for placement later. I asked the contractor to design the support structure for 8K loads on the garage floor but want 1.5 x the capacity built into the structure. I think he just doubled it since we have 2 4x4 beams supporting the garage beams front to rear and another 4 x 4 beam along the waterfront side (stick contruction).

Hopefully my multiresponse answers your question. The basement and shop will be 2456 sq/ft. The garage above will be 28 x 14 x 10ft high. The basement was a 9' 6" pour but we'll lose some height for cement/radiant heat insulation etc.

Kevin,
It's been great fun so far as the building movers hydralically lifted the house and rolled it onto the front lawn which allowed us to excavate for the new foundation. It took 7 days of solid hoe ramming to clear the 80 loads of limestone. I was not real popular with one of my neighbors...though I bought them a case of beer to build some goodwill. Since then the buidling movers have rolled the house onto the new foundation and installed all the steel beams that support the house/garage and deck. It is incredibly solid!!

Eborcim et al - Here's a pic of the 4x4 beam supports being leveled and later welded together.
