Instructions and Help about Why Form 2220 Foundations

Hi I'm Ben and this is the house I built out of shipping containers now I've been interested in shipping container architecture for quite some time but I had a really hard time finding good information about how to get building permits or how much would it cost well we did the research we documented everything that we did and now we're so excited to share with you what we learned so check it out this is episode 1 where we'll talk about buying containers getting building permits and pouring a concrete foundation in the spring of 2022 I bought 10 acres of land in Joshua Tree California it's a square piece of land about 650 by 650 feet and it has this nice little mountain right in the middle while I was waiting for the surveyor to finish up the site drawings I went ahead and ordered two shipping containers no I had heard like a lot of people have that you can get shipping containers for really cheap but in California you have to use a one trip conditioned container if you're turning it into a permitted house this is just so that you can provide documentation for what's been inside the container just to ensure that there hasn't been any radioactive or toxic stuff in there I also didn't order typical containers I ordered hi cubes which were a foot taller than a standard shipping container this is gonna give me more room for insulation running wiring and of course because we're in California sprinkler systems for fire suppression originally I was only planning on using one 40-foot container to build one tiny house but then I thought it'd be really nice to have a guest bedroom and bathroom for visitors and then when I checked in with my local building department they informed me that there was a 700 square foot minimum for houses which meant I would have to add a third container so I figured a home office and workshop would be great now even before I got the permit I was allowed to move up to 50 cubic yards of soil so I went ahead and started flattening out the piece where I wanted to place the house I rented a bulldozer and hired an operator to flatten out this whole area and it only took him two days we then started digging for the monolithic slabs which are going to support the containers originally we tried to do this with hand tools but there was so much rock in the soil was really slow going so we let the machine do the work and do we just use hand tools to clean it up afterwards not only are there big chunks of rock mixed into the soil there's hole veins of stone that go through it we use to buy lumber to define the perimeter of the slab and we drove stakes into the ground to hold these boards in place wood stakes kept breaking so we switched to these steel stakes that already had holes in them for screws and they worked really well Music we had a whole bunch of 20-foot long pieces of rebar delivered to the site and we began to reinforcement for the concrete the structural engineer had specified the size of the rebar and the layout so all we had to do was follow those drawings and wire it all together I focused on cutting all the short vertical pieces while the rest of the crew wired them all together this isn't the most difficult work but it does help to have a plan the whole thing starts to get pretty heavy because you're basically creating one big steel cage of rebar all wired together Music we spread out the 10-millimeter moisture barrier and then shoveled clean sand on the top of that I had always wondered how builders keep the rebar from just falling to the bottom of the formwork and they use these things called Dobies they're just little concrete blocks with wires embedded in them and they act as spacers this was a lot of work in hundred degree weather and it really made me appreciate all the stuff that goes on inside a monolithic piece of concrete originally we planned on embedding all of the drain pipes for the plumbing into the concrete slab but after laying out all the pieces and wrestling around trying to get them in the right position relative to the rebar we just felt we weren't gonna be accurate enough to line it up with exactly where the container would need to be so we just switched it out for a simpler option and just made the final drain go through the slab this just means we'll have to do the plumbing within the floor of the container itself now this is as far as we can go before having the building permits we certainly can't pour any concrete until we get the final sign-off California is a pretty regulation intensive state and here's the process we had to go through the process starts with getting the site surveyed in addition to measuring and marking out the topographical features which is really useful for showing how the site will drain the surveyor also researches the history of the site and defines all the boundaries and setbacks next up came the preliminary architectural design where we laid out all the spaces and features this design then goes to the structural engineer who creates a set of structural details and performs calculations to prove that this building will meet all the code requirements the building department gave us the option of either having the architect or engineer stamp the drawings we then compiled these designs into the construction documents and added in a whole series of reports and studies and forms that are all required by San Bernardino County is a complicated and expensive process because with each.
