Build Steps TA
This is intended to be a detailed guide to how we will build our Earthship.
Timing
Under way!!!!
Prototyping
- Water systems (this can be done before land)
- Water tank
- Build or order WOM
- Water pressure
- Send it out to a garden hose
- Build a root cellar with tire walls (make it north facing to keep it really cool)
- Lay tires
- Dig it out
- Cement the inside
- Put on roofing
Pre-Tires
- Find a source for tires and cardboard
- Do this (http://www.instructables.com/id/low-tech-3d-scanner-for-your-building-site/) to get a site survey
- Build work shed (2x4 frame with plywood walls. Simple) if there isn't one already
- Start collecting used water and glass bottles (do we need this?)
- Electrical?
- Do we have access to electricity? Yes - don't do anything now, No - connect to grid, or setup solar.
- Stake out footprint
- Backhoe
- Dig down below frost line
- Pile dirt around footprint (for later use pounding tires)
- Bury fireplace inlet
- Tamp and level ground
Tires
- Get tires and organize by size (or get all the same size tires)
- Layout and fill first row of tires. For each tire (here's a great video http://www.youtube.com/watch?v=cer3WKTOcy8):
- Position tire offset from previous row and 1" back
- Place cardboard in the bottom of the tire
- Screw the cardboard and tire in place (screw into previous row)
- Fill with dirt
- Pound dirt with sledge hammer
- Check level
- Add more dirt and repeat
- Its very important that each tire is level.
- Place drainage pipes - (I had it wrong, these are cooling pipes, which may not be necessary)
- Second row
- Third row
- Place thermal wrap
- Remaining tires and thermal wrap
- 3-4 weeks before tires, buttresses and stem wall are done, order the trusses
- Concrete buttresses
- Set the anchor bolts in the top tires and fill them with concrete
- After the concrete has dried, cover the tires in 2mil plastic, staple in place
- Place top plate of wood on tires (Vol.1 p102)
Framing
- Stem wall
- Dig stem wall trench
- line with plastic
- Build rebar cage
- Place rebar and Pour concrete
- Place support beams (in line with front of tires)
- Place roof supports
- Frame windows
- Beams should be in place above and below windows
- Place and square wood between each window (make sure it's square, can't check this enough times)
- Put in wood for windows with operable opening
- Put notching planks in place to hold window
- Deck roof (use screws not nails)
- Place skylights
Roof
- --Chimney--?
- Roof Layers (as I understand it):
- Metal roof
- OSB filler, pine perlins and heating tubes
- Hard insulation (poly-iso)
- Waterproof asphalt felt or tar paper
- Roof decking
- Trusses
- X bracing between trusses
- Insulation (perhaps Sprayed Polyurethane Foam insulation)
- Vapor barrier
- Ceiling
- Decorative tin ceiling
- Skylights
- Frame skylight
- Build glass top
- Weight skylight
- Rope
- Gutters (leading in to pools)
Windows
- Place windows
- Seal windows
- Place outside wood (to hold windows in place)
- Aluminum flashing
Interior
- Cover tires in concrete and fill gaps with bottles
- Cover floor in moisture barrier before pouring concrete
- Dig plumbing trenches, line with wood
- Concrete floor
- Frame sections (note that areas under the doors and any thing outside need to be separate pieces for insulation purposes)
- Concrete is not poured over planters
- Planters
- Dig down planters
- Line with plastic
- Install well pump
- Fill with gravel upto 4" from plumbing trench
- Run plumbing into planters so water falls 4" onto gravel, place bucket guard around plumbing
- Aluminum mesh
- Can/bottle planter walls
- Fill with dirt and plants
- Walls (drywall)
- Electrical
- Purchase PV panels, batteries and inverter
- Install PV panels
- Setup batteries in a utility room
- Setup inverter
- Run wiring to the house as needed
- Plumbing
- Install pumps to get water out of cisterns
- Install WOM
- Water pressurizer
- Run the whole thing out to a garden hose, use that for watering plants
- Bathrooms
- Run water to bathroom and put water heater in
- Bathtub
- Install bathtub
- Run water to shower nozzle
- Run drain outside
- Sink
- Install sink unit
- Run water
- Run drains
- Bathtub
- Kitchen
- Hot water at source
- Kitchen Sink
- Install sink
- Install disposal
- Run water
- Connect drain
- Oven/stove
- Install fireplace - The chimney and outside air pipe are already in place, potbelly stove just needs to be hooked up
- Bottle wall on main room
Post-Move In
- Water trench (so that water will flow around the house and not soak up and through)
- Wind Power
- Solar water pre-heater
- Thermal mass fridge/freezer
