69 GP Garage Addition

[69gp]

Well years in the making I finally pulled the trigger on adding to my garage. I basically started the work last May. Took a year to get a variance and install a retaining wall along the west side of my property. Currently have a 2 car garage with a 13'x17 ' workshop on the back side. Moving forward I will be adding a 12' x50' long wall with a bump out on the west side of the garage the back will be blown out to 24' x 24' addition. Basically will be an L shaped addition. Walls will be 13' high so I can get an RV inside and a Lift that I have in my shop now. I will be doing away with a covered porch and adding a small family room off the kitchen. The 2nd floor of the garage will have 4 dormers and will be unfinished for the time being. Heat in the family room and the garage addition will be radiant. Currently have electric solar on my house that I will also be adding another couple thousand watts to along with a solar hot water heater. Will be posting pics in the near future.

Installing the block wall consisted of 140 2x2 wall base blocks and 44 top cap blocks. Back fill was 3/4" stone

 

[69gp]

More of the wall going in. Had to do it in sections. There is 18" of stone below the first course of block. The top block only has about 4" of concrete exposed on the top and then drops down 6". I wanted this look so that I have more green area between the house and the wall. some of the blocks are a little off but I tweak them as I go along to get them straight.

 

[69gp]

Enough of the wall for now. Time to move on to the foundation.

Digging the footing was a lot harder than I thought. I only have an 8000 pound machine and I was hitting a lot of ledge and stone. It was pretty depressing and I was ready to just cover everything up and not move forward. But a good friend of mine who is doing the concrete for me talked me into just getting it done.

Now that's a boulder! Whew that looks rough, are you going to jackhammer through it? Or try to break the whole thing up and remove it?

No that's not a boulder the picture has a boulder. In New England i once had a site contractor tell me the whole area is one big rock with a little bit of dust on it.

And to answer your question ended up pinning the rock. will load a few pictures later on.

Looks like it will be a nice garage. So, do you have a 1969 Grand Prix that will be going in there?

Found even more ledge and a large stump in the middle of the footing. This was buried 2' below grade. Could not pull the stump out so I made a ramp and had a stump grinder come in and made it disappear real quick. Best $150 I spent.

 

[69gp]

Dug all the trenches and exposed all the ledge. There was a lot. Called a friend to see if he could bring a machine up with a hammer and break it out. Once he looked at it he just said to meet with the inspector and see if I could get away with just pinning the ledge. I had my doubts if that would work but he was pretty cool with just pinning it. He said that you are not going to get a stronger footing. So it was just drill and pin the ledge.

Looks good so far..
Keep us posted.Where are you located in MA,I have family on the north shore.

 

[69gp]

footing going in. Rained out on the first day.

Looks like your project is well under way. Congratulations.

My best car when I was younger was my 69 SJ Grand prix I loved that car

Walls formed up and almost ready for concrete. Stops need to be installed along with a few brick shelves. Concrete is a great construction material to work with.

 

[69gp]

This is what I came home to as the walls were being formed up. Was nice to see that crane above the roof line.

 

[69gp]

All walls poured, straight and level. No blowouts and no pump needed. Brick shelf installed all on the east and north wall for a stone veneer to be done at a later date. Inside of the garage I did install a brick shelf where I have the wall bumped out for storage. This was just to gain an additional 8" of floor space.

 

[69gp]

Forms removed from the wall. I scored a good deal on some used 3" and 4" Owens formula 250. I installed the 4" along back north and east wall. I installed the 3" on the inside. On both the inside and outside the insulation is sitting on the footing. I did include a picture of how I install electrical conduits when you use a Rapid style form. I use a 3/4" rigid 90 and then stub up with PVC to above the finish concrete height. Duct tape each end and secure the conduit inside the forms with wire to the form ties.

Few pictures of the existing garage foundation that is marked out for saw cutting & removal. I am also install a water management system to collect all rain water runoff from the roof. Will have 2-500 gallon tanks along the garage side with the capability to pump it to a 1500 gallon tank in the backyard. This will be used for lawn watering.

 

[69gp]

Getting ready to saw cut the existing garage floor in 2 locations and the garage walls.

 

[69gp]

Walls and piers were saw cut. I was going to do this work myself but decided to farm it out. I installed temp walls on the back of the garage wall and supported one beam on the side wall to lift all the weight off the concrete walls. I had to leave for a few hours and when I got back all the work was done. Fast clean and efficient. Only got one picture of the track saw doing the cutting.

 

[69gp]

Well they always say measure twice and cut once. That works as long as the measurement is correct. After measuring the newly cut pier openings something did not look right. Come to find out I was off by 24" in one direction. Unsure of where it went wrong but had to make the fix. I did have an existing saw cut in the floor that was offset by 23". Just took my old Milwaukee skill saw and put a diamond blade on it to cut down a couple of inches to give me a clean line. After it was just drill a series of 6" holes with my Hilti core drill and then break it all out. It only takes about 2 minutes to drill each hole. Drill one anchor and keep pivoting off of that point. After completing the work it looked as if it was done at the same time as all the other cutting with the exception of the nice radius on the corners.

 

[69gp]

Steel installed for the piers and small area under family room ready for concrete.

 

[69gp]

Removing the back concrete wall of the existing garage. Wedges can be seen that are supporting the wall after it was cut. I installed a temporary wall behind the one that is being remove. The area behind the wall is my old workshop. You can see the insulation under the slab. I did install radiant heat in this area but never used it. I plan on installing a sump pump in the garage so I did remove one end of the wall once it was pulled over. The wall section removed was 17' long by 36" high. Makes for a good solid base.

 

[69gp]

Got a good deal on the floor insulation for the garage. Will be installing radiant heat. The insulation is factory seconds but it works for me on the pricing. Will be installing poly under the insulation.

 

[69gp]

Demo started. Only took less than a day to demo the old garage down. Still some small items left to be removed.

 

[69gp]

Missed one shot of when I left in the AM. Roof was being removed. gives a rough idea of what was there before work started

 

[red]

Don't know how I missed this. Any updates?

Will try and post in the next day or 2. been a lot going on and have not had the time to stay current with the build.

 

[69gp]

Last section of the old existing foundation buried in a trench right beside where is was removed from. Some electrical conduits run under the slab. This is the easiest way to run electrical.

 

[69gp]

The new family room is being built over an existing concrete porch. Laid down 10mil poly followed by 1/2" Dow Tuff-R insulation over the whole area. 2x8 PT lumber was used for the floor framing. This was followed by 5" of foam insulation cut to fit between the floor joist. I then installed 1/2" pipe between the floor joist.

 

[69gp]

Radiant heat installed. Will be installing concrete to encase the tubing.

 

[69gp]

Overall shot of the family room along with the garage walls in the back ground. Concrete was poured between the floor joist for mass heat transfer.

 

[69gp]

Have not posted for a little while have a ton of things going on. Received a nice big load of framing lumber to get things moving along. Lumber company did a great job laying the material out so you don't need to pick through everything. Also the radiant heat pressure is holding up great so looks like no troubles with that end.

 

[69gp]

First floor framing almost done. I had a 12' section of wall bumped out 18" for shelf and cabinet storage. Will also leave the area below the cabinets for tire storage. This will prevent floor space from being occupied.

[69gp]

Hi,

Its been sometime since I last posted. Too much going on. Thought I would try and catch up to where I am today.

 

[69gp]

Few more pics. Framing still going on. We were getting a lot of rain when this work was going on.
