With the savings on the dome kit,

beautiful flooring and kitchen cabinetry can be purchased

Ai’s dome shell kit price is one fourth to one half less in cost than the shell materials cost for a wood dome, monolithic dome or conventional house (exterior walls, roof trusses, plywood, tar paper, shingles, 3 1/2″ thick insulation, siding, soffits, gutters, shell and ceiling/exterior wall - wall board, etc).  Besides saving on your shell materials cost versus the materials for the shell of a conventional house….you receive more with the Ai Dome Home….greater energy efficiency (insulation comparable to 11″ of fiberglass batting), greater strength and lower maintenance because the exterior of your dome home is concrete with no wood in it or on it to rot, to burn or for termites to eat.

Why is the Ai Dome Kit so reasonable in price?  Mainly it is because of the simplicity of Ai’s component panel, the panel being manufactured in a factory and the philosophy of our company that each client pays for only what they need; i.e. building plans, engineer seal cost, energy report is paid by only those who need it.  To learn more about our philosophy, view Philosophy.  To learn more about Ai’s panel composition, view Composition.

Q: Do you have an engineering statement about your dome panels that can be submitted to my building department?

A:  Yes, to view the statement click on Engineering.

To view a building plans sale pricing chart, view Plans Discount.

Ai’s Building Kit and Option Pricing does not include the costs for the Building Plans, Engineer Fee for alternative foundation design other than slab, Engineer Seal on the building plans (if needed), Energy Report (if needed), 2×4’s for the temporary wooden rib system, Semi-truck Shipping, Fork Lift rental to unload the truck at your site or the cost for a hoisting mechanism to lift the panels into place. 

Please view Kit Assembly Consultant file and scroll down the page to view the yellow and blue charts showing estimated labor costs, hoisting mechanism costs, etc.

The money you save by purchasing Ai’s Building Kit can pay for all of the above costs.  For example if you purchase a $30,000 building kit from American Ingenuity,  the shell materials for a conventional house can cost at least $10,000 to $15,000 more especially if you build the conventional house energy efficiently with 2×10 walls and 10″ thick insulation.  Ai asks you to make a comparison chart comparing what you receive in the Ai kit compared to the contents of a log home kit or conventional house kit or Deltec kit.

The most successful dome kit assembly occurs when the home owner or the home owner’s builder hires the independent Consultant to supervise the Kit Assembly. Once the shell is erected, then you or your local contractor hires local subs to finish the conventional jobs of plumbing, electrical, framing, flooring, cabinetry, window and door assembly, etc.  To learn more about the Consultant, view Consultant.

Dome Construction Overview

The following are items not provided with the Ai dome building kit that are needed on site to assemble the panels, finish the seam concrete between the panels and finish the building options concrete (entryways and dormers), etc.

  • Mortar Mixer (4-8 cubic foot capacity, do not use a cement mixer)
  • Bags of Portland Cement (to fill the seams between the panels and apply on the entryways and dormers)
  • Cement trowels
  • Sand: Masonry Sand or Stucco Sand…no rocks in sand.
  • The following is based on the dome having two entryways, four window dormers, one door dormer and no cupola.

  • Work Platforms:
    • For work platforms greater than 6’ long use a 2×4 under a 2×10 platform.
    • You will use scaffolding brackets, 10d duplex nails, 5/16” lag screws, 2×4’s 10’ long.
    • The work platform can be extended around the dome by overlapping another 2×10 and adding another post.
    • Nail overlapping platforms together.
    • Each platform will hold one person.
    • Be sure to use safety rope and a harness.
  • In the Kit Assembly Manual is complete Tool, Material, Utility listing.

Hoisting Methods

The methods used for lifting the panels includes: Man Lift, cranes and Highlifts (all terrain scissors forklifts often used by roofers).  To view more on hoisting methods, click on Lifting.

Monthly rentals on transverse lifts also called Boom Lifts, Horizontal Boom Fork Lifts, Roofing Lifts, Shooters are available from National Rental Chains like US Rentals, Hertz Equipment Rentals, United Rentals, etc. The companies can be found in the telephone book.

The panels for the domes are best placed using a man lift or crane that is capable of lifting 300-400 pounds, 25 feet up and 25 feet out.

With a four-person work crew, use of a temporary wooden rib system and proper bracing of the panels, a row of panels of a 40′ dome can be placed in about a day of crane time.

Man Lifts or cranes can be rented by the day, week or month. Sometimes larger domes with three to five entryways, the rental of a crane for one month maybe most cost effective. Besides lifting the panels, the crane can be used to lift buckets of cement. Cement is used to fill the seams between the panels and to stucco the entryways, dormers, link and or cupola.

Wooden Rib System Is Needed As Temporary Support During The Dome Kit Assembly

American Ingenuity’s Dome Building Kits are erected using a system to temporarily hold the panels in place until the seam concrete and concrete on the entryways, dormers, cupola and link has cured and the entryways and dormers are framed in. The system is dismantled upon completion of the dome and the 2×4’s are recycled as part of the interior framing. For example, around the perimeter of the second floor a two foot tall knee wall is built. 2×4’s not tall enough for interior framing can be used for the knee wall. Behind this knee wall, electrical, plumbing or ducting can be run or the space can be used for storage. View Rib.

The Rib System consists of using your own 2×4’s (that have been cut to length, holes drilled and the ends painted red, white or blue (or you can purchase them cut, drilled and painted from Ai…call 321-639-8777 for pricing) and the steel hubs on loan from America Ingenuity to assemble a free standing framework which matches the geometry of the dome.

  • The rib system dictates exact panel placement.
  • Once all the seams, entryways, dormers, link, cupola, etc. have been concreted, entryways and dormers framed in and the concrete has cured, the rib system is disassembled, the hubs are returned to American Ingenuity and the 2×4’s are recycled as interior framing.
  • As the building kit is being assembled upon the temporary wooden rib system, extra 2X4’s are used to support each steel hub.
  • The advantages of using the Rib System Option versus the Radial System Option are:
    • Since the Rib System reflects the dome geometry, a panel cannot be inadvertently positioned incorrectly.
    • The Rib System is most suitable for accurate assembly.
    • The hub rental charge is a $800 deposit with the hubs being kept for five months. After that the rental fee is $20 per month. If the hubs are returned to us intact within the five month period, the complete $800 deposit is returned. The hubs are returned to Ai via UPS or common carrier at the client’s expense.
    • The Rib System is bolted together from 2×4’s and color-keyed hubs. 

Tools and Materials needed to assemble the Rib System (complete list is in the Manual):

  • Set of steel scaffolding to reach at least the dome height plus three feet (the dome height can be estimated by taking one half of the diameter of the dome.)
  • 9/16” wrenches and ratchet
  • 46 hubs (borrowed from Ai for three frequency dome), 255 bolts, nuts, and washers purchased from Ai
  • 15 diagonal braces: 2x4x8’ studs
  • Chain and couplers to make the lifting harness which is used with the lifting spikes
  • Precut, holes drilled and color-coded wood ribs (2×4’s used are lightweight wood, not pressure treated)
    • The 34′, 36′, 40′, 45′, and 48′ rib system requires 135 - 2×4’s
    • The 22’ and 27’ need 75 - 2×4’s
    • If you do not want to buy the 2×4’s and cut them to length, color code them and drill the holes, purchase them from American Ingenuity. Due to the fluctuating cost of 2×4’s, we estimate the cost when ordered.
  • Two pounds 12d or 16d common nails and 60d nails (in top of hub support)

 The American Ingenuity dome building kit does not include doors and windows. There is such a variety and varying price points possible, we leave their selection and local purchase up to each client. The floor plan you select will determine how many entryways or dormers you will have. Within the entryways and dormers {eye brows}, you or your framing subcontractor installs a vertical wall to frame in what ever standard doors or windows you have purchased locally.

No interior items are included except for the dome shell wall board. Ai believes you should not pay shipping on conventional items that you can purchase locally such as: foundations, basement wall kits, second floor joists, stairs, plumbing, electrical, framing, flooring, kitchen cabinets, bathroom fixtures, lighting fixtures, etc.

The component panels do not come with any paint on them. Ai does not add any color to the concrete. On site concrete is applied to the seams so if Ai painted the panels or added color to the concrete it would not match your seam concrete. The concrete shell is primed and painted after the entire building kit is assembled. The painting should include a concrete primer and two coats of good quality paint. Ai dome owners recommend Ames products to prime and paint the dome which can be purchased at Ace Hardware and True Value for similar Home Depot and Lowe’s paint pricing. When on Ames site click on Local Dealers to find other suppliers in your area. The dome can be painted any color, tan, blue, green, etc. preferably a light to medium color to reflect the sunlight. The following gallon calculation is for each coat of primer or paint.
