I have just started a project to build a garage/workshop in my backyard. The house was built with a separate 20x36 2 car garage/shop in the backyard in addition to a 2 car garage attached to the house. The "back" garage has an 8' ceiling height and bathroom already which has been nice, but I need more space to put in a 2 post lift or two.
The plan is to extend the 20x36 garage into a 36x45 garage. the 36' is the width and the 45' is the depth. This should allow for 3 extended "bays" for 2 cars nose to tail in each bay. The garage will be constructed so the entire interior space is free of any support columns - this allows maximum flexibility and maneuvering inside the structure.
My goal is to be able to pull thru the entire structure with my pickup and car trailer to haul my track cars. The ends of the garage will have both a 16' and 10' garage door to allow for easy clearance of vehicles.
Because I want to put in some car lifts, it was important to find out what concrete characteristics were specified by the manufacturer. I have decided to use a rotary 2-post lift and they recommend a minimum of 4-5" of 3000 psi concrete. My contractor has overbuilt the foundation to exceed the requirements, and we are using 6-7" of 5-sack (~3500 psi) concrete poured over #5 rebar lattice and 36" deep beams. This thing should help prevent any problems with any lift fixation.
existing structure:
foundation preparation:
note the depth of the beams and slab:
concrete poured:
rotary lift SPOA7LC (from Viperforums)
update #1:
original slab was poured 2' too short due to error by the architect! So another 3' was poured along with 4 new piers and a double beam on the end. Now the garage will be 36x46 instead of 36x45.
Also my contractor discussed with me that it will be cheaper to demo the entire existing garage and rebuild rather than tie into only 2 of the walls so tomorrow the old garage gets smashed.
This has given me extra time to plan and source out a lift - I will actually be using the Rotary SPOA10-RA lift which can be lowered to 11' and save me about $2k from having to buy their special low height SPOA7LC (and this LC lift has been discontinued). I also am planning on plumbing an 80 gallon air compressor with retractable air hose reels on the ceiling, and T8HO fluorescent light fixtures.
update #2
old garage is no more:
framing started & completed in 2 days:
16" I-beam joists:
versalam garage door headers:
36' steel dropped I-beam runner:
framing completed:
my precious has arrived:
I'll try to update this as it goes along.
