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.

  • Suspension Rods and Top and Bottom Plates (can be purchased from AI)
  • Shovels
  • 5 gallon buckets
  • Wheelbarrows
  • 25’ Tape Measures
  • Ladders 16’ and 32’
  • 2×4’s for the temporary support system.  The 2×4’s are cut to specific lengths, holes drilled for the bolts and each end painted red, white or blue.  Ai can cut them to length, drill the holes and paint each end.  For pricing call our office:  321-639-8777.
    • The 34′, 36′, 40′, 45′ and 48′ each require 135 – 2×4’s.
    • The 22′ and 27′ each require 75 – 2×4’s.
  • Additional supports for the temporary support system – around 20 – 8′ 2×4’s and 33 – 10′ 2x4s for smaller domes.
  • Steel Scaffolding
  • 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.
  • Rental of a hoisting mechanism
  • On your Order Form there is a listing of items that come with your kit with quantities: for fibers, admixtures, bonding agent, cans of expanding foam, metal dispensing gun, cleaner for gun, C-rings small and large, C-ring pliers, two steel cables, etc.  Due to spillage and loss at job site, our clients tend to purchase additional quantities of these items that are shipped on the truck with their kit.  This saves on later shipping costs.
  • Labor to install the cement in the seams, entryways, link, cupola, and dormers. View Kit Assembly Consultant to learn more about this.
  • Labor, Joint Compound and Tape to finish the interior shell wall board seams.  Primer to prime the shell drywall.
  • All interior items (excluding the interior shell wallboard which comes with the Building Kit):  Plumbing, Electrical, Framing, HVAC, Bathroom fixtures, Lighting Fixtures, Kitchen Cabinets, Appliances, Foundation, Flooring, Stairs, Lift or Elevator, Windows, Doors (exterior and interior).  Due to the wide assortment of these items and varying price points, Ai does not believe you should pay shipping on items that you can purchase locally.  View Dome versus Stick Built to learn more.

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.

Building an American Ingenuity dome building kit can be a Do It Yourself project or a Kit Assembly Consultant can be hired to supervise your workers or your builder’s workers.  Please scroll down this page to learn 1) about this specialist; 2) materials/tools/equipment needed for kit assembly; 3) charts showing approximate assembly time and approx. costs by dome diameter size when hiring the consultant.

Third row panel being lifted into place.

The dome kit can be assembled by owner builders or the home owner or the home owner’s builder can hire the independent Consultant to supervise their workers to assemble the dome kit to the stage of having all the panels placed with one layer of concrete in the seams and on all the entryways and dormers.  The consultants travel through out the USA and internationally.   When hiring a local builder, best to pay him cost plus versus an overall bid. 

Great news as of May 2017,  Ai knows of a licensed Florida Builder, Randy Dixon, who will travel to some USA areas with 2-3 men to assemble the kit on your prepared foundation. Then yourself or your local builder’s subcontractors can install the doors and windows, prime/paint the exterior and finish the interior with locally purchased materials.  If his crew does not travel to your area, he will travel as independent consultant.  If you are considering hiring Randy and his crew, it is best to pay them by the hour rather than have him bid the project where he will need to include in the bid a cushion. 

Ai knows of three other independent kit assembly Consultants, Kevin Killian (Florida), Steve Cooke (California) and Bob Bailey (South Dakota) who will travel to your site to supervise Aidome kit assembly as well.  

In Brevard County Florida, Builder Ray Vince with Pistolatun Inc. will bid the dome kit assembly and the finishing of the dome and complete the financing for those who qualify.   He also has land to sell in Palm Bay Florida plus knows of our property for sell in the County.  His info is 76 E. Merritt Island Cswy. #205, Merritt Island Fl 32952.  His phone number is 321-284-8116

In Texas, builder Don Simons with NewTech Builders, Inc. states he will bid the dome kit assembly and the finishing of the dome for Texas and surrounding states.  He has a superintendent who will travel to your site, interview subs and hire subs for the site clearing, driveway installation, foundation installation, dome kit assembly, electrical, framing, plumbing and finishing of the interior and exterior of the Aidome.  His number is 979-212-6000.

Within the building plans is a nomenclature sheet where each panel is identified with numbers or letters showing where each panel is installed.

If you have a deadline for your kit assembly or are assembling the large 45′ or 48′ dome, consider hiring the consultant to save  up to  2-3 weeks of labor costs.  Please scroll down to view charts listing estimated kit assembly times.  Click on Kit Assembly and Construction Overview to view other assembly photos.  Our finished cost per sq.ft. page discusses geodesic dome cost.  To view stock dome floor plans, click on Plans.

The Consultant will travel to your construction site and supervise your workers or subs or your contractor’s workers for the dome kit assembly with the first layer of concrete in the seams and a “scratch coat” on the entryways and dormers….and then he goes home.  FYI, he does not apply concrete….that is done by your concrete workers.  He supervises that the fiber concrete is mixed properly and installed properly.  The dome owner or their builder hires a finish stucco person, to apply and finish the second layer of concrete in the panels seams and on the entryways and dormers. Usually second layer of finished concrete can be applied in around one hour per seam for a flat seam or up to 1 1/2 hrs for a custom rounded seam.  Approximate number of seams in a three frequency dome (30′ – 48′) is 126 – number varies depending on number of entryways and dormers. A two frequency dome (15′-27′) has around 62 seams.   Prior to second layer of concrete, a bonding agent supplied by Ai is applied to the first layer of concrete that needs to set 30 minutes prior to the second layer of seam concrete being applied. The interior finishing is completed by you or by your contractor hiring local conventional subs (plumbers, electricians, drywall finishers, framers, etc.) to complete the interior finishing and the installation of your locally purchased doors and windows per your dome plans.

Prior to the availability of a Kit Assembly Consultant to supervise the dome kit assembly,  some of Ai’s dome owners had to hire a contractor who generally had never assembled a dome before.  As a result the contractor would tend to over charge because he did not know how long it would take or what problems would arise.  The Kit Assembly Consultant can provide you with references from previous American Ingenuity Domes he has assembled so you can assure yourself that your building kit will be assembled correctly and in a timely fashion. This Consultant works directly for you or your general contractor as an Independent Sub-Contractor.  The standard daily rate for the independent Kit Assembly Consultant/Specialist is $300.  If the Specialist is not paid mileage to drive to your site, he is reimbursed for a round trip airfare, round trip shuttle transport cost between his home & the airport & car rental cost for the time at the job site.  The dome owner arranges and pay for lodging with Wi-fi availabilty in vicinity of grocery store & restaurants.

The use of a consultant for one week can save up to two to three weeks on your shell assembly time and assures the kit is assembled accurately per the building plans.

The cost of materials to complete the assembly of the kit are not included in the labor estimates.  Many times rental costs are less for one month than daily or weekly rental costs.  As a result sometimes monthly rental is shown because it is cheaper. Equipment rental costs are from United Rentals.  

Estimates below are based on 2015-2016 construction data.  In 2017 there is a shortage of concrete workers which drives their pay up.  We will review the estimates in this post and update as data is collected.

The assembly time estimated below is based on a dome kit having one entryway, two dormers and no cupola built on a slab foundation.  

  • For each additional standard entryway: add one day for the consultant and 24 hours for the workers.
  • For a garage entryway two frequency: add 1 day for the consultant and 24 hours for the workers.
  • For each additional window dormer: add 2 hrs for the consultant and 12 hours for the workers.
  • For each additional door dormer: add 3 hrs for the consultant and 18 hours for the workers.
  • Cupola: takes three partial days because the concrete has to have time to cure during each process.  First partial day of 5 hrs: concrete beam around top opening is formed and poured.  Second partial day of 5 hrs: concrete corner columns are framed and poured.  Third partial day of 5 hrs: set top five panels, attach overhang panels & apply first coat of concrete in the seams.  During the rest of the partial days, workers can complete window dormers or door dormer installations.If the rib system has not been cut and prepared: add one day for the consultant and 8 hours for the workers.
  • If you want to speed up the kit assembly, consider renting a scissor lift for inside personnel movement (instead of using ladders and scaffolding) and renting a Straight boom lift – man lift or cherry picker- for outside personnel work (instead of ladders, planks and scaffolding).   A 19-foot electric scissor lift approx. rental is $350 to $500 per week, and $900 to $1,200 per month.  A 40′ straight boom lift approx rental is weekly $956 or monthly $1,915.

*Worker Hourly Costs vary depending on your construction location
Plus travel costs or airline ticket for the Consultant
 The Consultant/Specialist is reimbursed for a round trip airfare, round trip shuttle transport cost between his home & the airport & car rental cost for the time at the job site.  The dome owner arranges and pay for lodging with Wi-fi availability in vicinity of grocery store & restaurants.

The dome owner or their builder hires finish stucco person(s), to apply and finish the second layer of concrete in the panels seams and on the entryways and dormers. Usually second layer of  seam concrete can be applied in 50 minutes per seam for a flat seam or up to 1 1/2 hrs for a custom seam.  Approximate number of seams in a three frequency dome (30′ – 48′) is 126 – number varies depending on number of entryways and dormers. A two frequency dome (15′ – 27′)  has around 62 seams.

To unload the dome kit from the semi-truck, rent a fork lift and have 2-3 workers available.  Ai provides a document that describes the unloading process.

The dome owner provides three to five good concrete workers (depends on dome size).  Materials used in the shell construction are to be provided by the dome owner on site before the Kit Assembly process begins.  The bags of cement don’t have to all be delivered in advance but as soon as first needed during the assembly.

Due to possible injury on a job site, have some form of insurance.

The following are items required at your job site:

Cement
  • Portland Cement in 94 pound bags (prefer Type III) (first number is the diameter of the dome/second number is bags of cement):  22′ – 30, 27′ – 40 (two frequency dome panels are larger so require less cement), 30′ – 70, 34′ – 79, 36′ – 83, 40′ – 90, 45′ – 100, 48′ – 106.  These bag numbers are based on the dome having two entryways, four window dormers, one door dormer and no cupola.
  • For each additional entryway add: 22′ – 3,  27′ – 3.5, 30′ – 4.0, 34′ – 4.5, 36′  – 4.5, 40′ – 5.0, 45′ – 5.0, 48′ – 5.5
  • For a cupola add: 30′ – 4, 34′ – 4.5, 36′ – 4.5, 40′ – 5.0, 45′ – 5.5, 48′ – 6.0.
  • For an additional door dormer on any size dome add 2.5 bags of cement.
Masonry or Stucco Sand
  • Sand in cubic yards; 27′ – 5, 30′ – 8, 34′ – 9, 36′ – 9, 40′- 10, 45′ – 11, 48′ – 12.  These computations are based on the dome having two entryways, four window dormers, one door dormer and no cupola.
  • For each additional entryway add cubic yards of sand: 22′ – 0.3, 27′ – 0.4, 30′ – 0.4, 34′ – 0.4, 36′ – 0.5, 40′ – 0.5, 45′ – 0.5, 48′ – 0.6.
  • For a cupola add cubic yards of sand: 30′ – 0.4, 34′ – 0.5, 36′ – 0.5, 40′ – 0.5, 45′ – 0.6, 48′ – 0.6.
  • For an additional door dormer on any size dome, add 0.3 cubic yards of sand.
Misc Items:
  • 2×4’s cut to length, holes drilled & ends painted for the temporary wooden rib system…can be purchased from Ai.
  • Water Source and water hoses
  • #3, #4 and #5 rebar (per the Building Plans)
  • Concrete Blocks; 8″x16″
  • Electric Power or Generator
  • Extension Ladder; 26′
  • Mortar Mixer – Do not use a cement mixer because it does not have spinning paddles.  Spinning Paddles are required to obtain a thorough mixing of the cement, sand, fibers and admixtures.
  • Lumber for Bracing the steel hubs, entryways and dormers
  • Wheelbarrows
  • Step Ladders
  • Two Saw Horses
  • Tarps to cover Cement and Sand
  • Ropes and chains
  • 5 gallon Buckets
  • Toilet facilities
  • Brushes to apply bonding agent
  • Soft Steel Tie Wire
  • Wire Cutters
  • Sponges to sponge finish final layer of concrete
  • Place to store boxed items out of the weather….C rings, pliers, cans of expanding foam, 1″ EPS Sheets, etc.

Additional Items Required:

  • Steel Hubs for Rib System (borrowed from Ai with a deposit placed)
  • Purchase bolts, nuts, washers to use with the hubs (purchased from Ai). During dome assembly most of these items are damaged; therefore they are not returned to Ai.
  • 2×4′ ribs for temporary wooden rib system – cut to length, holes drilled and ends painted. Can be purchased from Ai.
  • 9/16″ socket & ratchet and one 9/16″ wrench (use for bolts with HUBS)
  • Lifting Spikes set of 4 (purchased from Ai for $100). During panel lifting the spikes get damaged. If you have two domes, please order two sets of lifting spikes.
  • Panel Lifting Harness – custom make the harness from Ai sketch using four strands of 1/4″ chain 7 foot long & Quick Links.
  • Zinc or Galvanized Quick Links – To make the harness purchase Quick Links: 1 – 3/8″, 2 – 5/16″, 8 – 1/4″   2 – 3/8″, 4 – 5/16″.  During panel lifing the Quick Links are disconnected quite often so the threads become damaged.  Purchase additional Quick Links to have on hand for replacements….8 – 1/4″, 2 – 5/16″
  • Hoisting Mechanism; preferably rent 45′ Man Lift for dome on a slab or rent a 60′ Man Lift for dome built on basement.
How Long Will Shell Assembly Take with a Consultant?

Using three to five good concrete workers and depending upon the size dome, soil condition around the dome to allow movement and placement of the panels, type of hoisting mechanism and prevailing weather, shell assembly can take from 9-16 days if your dome kit includes two entryways, four dormers and no cupola and if dome on a slab. Once you know how many entryways and dormers are needed for your floor plan, Ai’s office can give you a more specific estimate on shell assembly time.  Click on Hoisting Mechanisms to learn more.

Typically it is cost effective to only have the Consultant stay for the assembly of the temporary wooden rib system, all panel placement including building options (entryways, dormers, link, cupola, etc.)  are assembled which includes the first coat of concrete in the seams and a “scratch coat” on the entryways and dormers.  Then your workers can:

  • apply the bonding agent and finish coat of concrete in the seams and on the building kit options. Remember to always water down all “old concrete” in the area you are working and all around the area working before applying bonding agent.
  • Follow Waterproofing document in the manual. The type of primer, tape and paint that is used, determines whether primer is applied before any areas are taped or patching compound applied prior or after priming.  Two coats of paint are applied. The following paints have been used by Ai dome owners:Behr’s top of the line exterior latex paint is Marque. Seabrook Texas dome owner loves this paint. He uses semi-gloss.  Marque has the most titanium.  – Home DepotBehr’s Premium Elastomeric Masonry, Stucco & Brick Paint –Home DepotAmes Research Labs: Maximum – Stretch, at participating ACE & True Value Stores (if using Ames see separate Ames doc because specific type sealants and primer need to be used with Ames Paint….TT3 sealant cannot be used)Sherwin Williams: Loxon XP Paint, Loxon Primer and ConditionerRichards Paint:  Rich Flex 245; use Rich Flex Alkali Resistant 100% Acrylic Masonry PrimerSeal Krete Paint (pigmented) –Home Depot
  • frame in and install the exterior doors and windows. (can be done earlier)
  • complete rough framing, electrical, plumbing
  • finish the interior shell wallboard with fiberglass adhesive  tape/joint compound. To blend the drywall seams to the DensArmor, skip trowel joint compound over the dome shell drywall.
  • prime then paint the dome shell interior gypsum
  • complete rest of construction phases.

As far as finishing the exterior seams with a second layer of fiber concrete, no need to pay to have the consultant on- site for this.  Best to hire a local finish stucco person by the hour with the conditions if he does timely work and good work, you will retain him.  If you are not satisfied with his work or speed, pay him for the time worked and replace him.  The second layer of concrete can take 20-30 minutes to apply per seam after the bonding agent is applied.  The bonding agent supplied by Ai needs to set 30 minutes before the second layer of concrete is applied. Approximate number of seams is 126…number varies depending on number of entryways and dormers.

Once your Building Plans have been ordered, American Ingenuity can estimate the number of days needed to assemble the shell.  Each floor plan varies as to the number of building kit options (components) needed to complete the shell kit; i.e. cupola, link, entryways, door dormers and window dormers.  Building Options take longer to install than triangles do.  To learn more about Building Options, click on Options.

You or your contractor hires local subcontractors to perform the typical jobs like forming and pouring the slab, plumbing, electrical, framing, drywall finishing, etc. Ai does not believe you should pay someone to come in from out of county or state to do work that your local subs can perform.  Click on Finished Cost, to learn about what it will cost to finish your dome home.  Click on Builders and Assemblers to learn more.

Contact Ai if you are interested in utilizing the Consultant/specialist…..321-639-8777…..9-5 Eastern Time.

If you are employing a contractor to assemble the kit, an experienced consultant on the construction site will make the assembly go faster and reduce costs.  The contractor provides the additional workers needed and the consultant directs them through the assembly of the kit.

If you choose to hire the Kit Assembly Consultant, the following labor estimates assume the following:

  • You have hired three to five good concrete workers depending on the size dome.
  • The slab/foundation and floor are completed.
  • A Hoisting Mechanism/Lifting Device/Boom Truck or Crane or Man Lift is on site to move the panels, to set the panels in place and lift buckets of concrete.
  • Additional equipment is on site, e.g.: wheelbarrows, ladders, scaffolding, mortar mixer, etc.
  • The first floor of the dome is not elevated above ground level.
  • The construction site is readily accessible for equipment and personnel.
  • Your local Laborer cost per hour is $15.  The labor cost per hour varies depending on your construction site location.  In California labor costs can be $25 to $30 an hour.
