RAISED WOOD FLOOR & CONCRETE SLAB ON STEM WALL

The American Ingenuity concrete domes can be built utilizing the same foundation choices as conventional housing: a) a monolithic slab;  b) poured footing with a stem wall and then a poured slab on fill;  c) poured footing with a stem wall and then a raised wood floor;  d) basement; e) pilings & platform depending on which is more advantageous for your area and soil conditions.

American Ingenuity’s design team can design your foundation per your requests, your soil’s report & your building department requirements.  Please call us at 321-639-8777 to discuss your foundation possibilities.

If your building site is in a cold climate, your building department will require the footers to be designed below the frost line.  At no cost to you, Ai can call your building department and obtain this info & the other design criteria the building department requires.  Ai staff will then call and email the data that was learned to you.

All foundations are designed and laid out so a rebar extends up three feet out of the footing into each of the riser wall seams. Hook tie down rebars are installed under the riser panels.  Once the riser wall seams (horizontal and vertical) are filled with concrete the dome is secure to the slab.  The riser panels aligns flush with the edge of the foundation.  Where all entryway panels meet the dome panels, a rebar is installed that overlaps rebar coming out of the footings.  Around the lip edge of all entryways, a beam is poured that contains rebar which overlaps rebar out of the footing.  Within the set of Building Plans there is a foundation blueprint and a foundation detail blueprint.

The dome kit can be delivered before your foundation is installed. The EPS panel edges are painted at Ai’s factory. The paint protects the EPS from UV light.  The dome kit can be stored on your site up to 2-3 months in nonfreezing weather waiting for the installation of your foundation.  If the kit will not be assembled for time longer than that, call us for instructions on how to protect the EPS.

The type of foundation that is built for your new dome depends on your budget and which type foundation is more advantageous for your soil type and terrain, what your building department requires and what your soil’s report recommends.  For Ai to design any other type foundation than our standard concrete slab, a local engineer is hired.  He requires a Geotechnical Engineering Report (soil report) where soil borings are completed on your property with a soil engineer recommending what type foundations can be built for that type soil.  Show the foundation recommendations to a local foundation subcontractor or builder to determine which type foundation fits your budget and meets your needs.  Provide the foundation type to Ai and we will provide a quote for Ai to design that type foundation and we will contact the local engineer to obtain his fee (from $200 to $500) to review the soil report, calculate the load of the dome and its interior floors to determine joist size, spacing, etc and provide design details for that type foundation for Ai to incorporate within your building plans   The quote will also include the fee for the engineer to seal the custom foundation plans and the dome building plans. 

When you are determining your foundation type, at no cost to you, we can email sample blueprints for that type foundation for your builder or subcontractor to review and bid installation.  Once your building plans are finished, we email the finished pdfs so you can email to subcontractors for bids.   Prior to the foundation concrete being poured, at no cost to you, email photos and we will review for correct rebar locations.  Even during kit assembly, email photos and we will review for correct rebar and cable installation prior to seams or entryway/dormer panels being concreted.  

The only thing unusual about our foundation is its shape.  Because our dome is lighter than most other buildings, it has less loading on the foundation.   The multiple sided foundation for our dome is only slightly more difficult than a conventional house and should not affect the cost more than 15% at most 25%. 

 

Due to three foot frost level, stem wall is built above footer to keep footer below frost line.
