WHO WE ARE

FROM IDAHO TO THE WORLD

Barry South, the President of Dome Technology is an original co-patent holder of the tech-

nology of building thin shell concrete domes by spraying foam and concrete to the inside of a pres-

surized, dome shaped, fabric air form. In 1975, Barry and his brothers began experimenting with

inflatable air forms, spraying them with polyurethane foam to develop initial rigidity, then adding

rebar and continuous-spray concrete to form the completed structure. A year later, they created

their first dome using the continuous spray-in-place process. They built the first dome home in

1977 and two years later were awarded their first United States patent for the construction process.

The first patent was followed by a Canadian patent in 1980 and a second United States patent in

1982. Additional registered and pending patents for various dome construction applications have

followed in the ensuing years.

By 1986, Dome Technology had constructed 100 domes and two years later built its first

dome in Europe. In 1989, the company built 28 domes for grain storage in the Middle East. By

1994, Dome Technology had constructed 200 domes along with its first dome in Eastern Europe. A

year later the company built its first dome in Asia, and three years later built its first dome in South

America, as well as the world’s largest clinker dome silo (at that time) built in the United Arab

Emirates. In 1988, Hurricane George struck three of the company’s domes in Puerto Rico, none of

which sustained any damage. No structural damage has occurred to dome structures that have been

in the paths of recent hurricanes in the southeastern United States including Hurricanes Charley,

Francis, Ivan and Jeanne (2004) and Dennis and Katrina (2005). One of our storage domes in Man-

zanillo, Mexico withstood 6.2 and 7.8 Richter scale earthquakes, while most surrounding port fa-

cilities and structures were heavily damaged or slipped into the ocean.

In 2000, Dome Technology built the then largest diameter dome ever built, a 280-foot di-

ameter church structure in Birmingham, Alabama. In 2007, we completed an industrial coal storage

dome in the Midwest with a diameter of 300 feet and an apex height of 178 feet, making it the cur-

rent largest thin-shell volume dome in the world. The Alabama church dome remains the largest

architectural dome. Over the ten years prior to 2002, the company averaged in excess of 20 domes

per year. With good business resiliency planning following serious setbacks caused by the Septem-

ber 11, 2001 terrorist attacks, we began diversifying our products and services and expanding our

markets for non-industrial dome applications. We have been successful in doing so and have ex-

perienced phenomenal growth over the last several years.

NEW MARKETS

Beginning in 2005 and continuing into 2006, the industrial market rebounded strongly while

the architectural market, particularly schools, remained strong. 2006 and 2007 marked an important

entry into large recreational applications for our domes with completion of our first hotel-integrated

indoor water park under an elliptical dome for a major chain hotel in Ohio. 2007 and 2008 showed

very strong domestic and foreign markets with foreign dome construction projects pending, under-

way, or completed in Canada, Latvia, Morocco, and Romania. Dome storage for coal and other ma-

terials associated with power production installations, as well as storage of fertilizers, are important

emerging markets where Dome Technology is leading the way in innovation and dome turnkey

projects.

LEADERSHIP IN ENERGY AND ENVIRONMENTAL DESIGN (LEED®)

Dome Technology is a member of the U.S. Green Building Council (USGBC) and under-

stands LEED Green Building Rating System™. The LEED Rating System is the nationally ac-

cepted benchmark for the design, construction, and operation of high performance green buildings.

Many of our team is LEED Accredited. Dome Technology will work with your architect or with C-

Shells (a local architectural firm specializing in dome-related structures) to design and build energy

efficient buildings that are 30%+ more energy efficient than ASHRAE 90.1 baseline energy effi-

cient buildings. This equates to 6+ points in the Energy and Atmosphere section of the LEED rat-

ings system and possible additional points under the Innovation and Design Process category. The

number of LEED points a dome structure can give a client may mean the difference between a sil-

ver certification and a gold certification.

Besides the energy efficiency, the distinctive design of the dome creates a distinctive land-

mark structure for school districts, cities, towns and churches, offering publicity, general curiosity

and traffic to your building.

Domes can also be designed as community disaster shelters to provide a safe building dur-

ing tornados, hurricanes and other natural disasters.

FABRICSPAN® STATE-OF-THE-ART AIR FORM MANUFATURING

FabricSpan is housed in a 65’ by 350’ facility with a working floor space of over 20,000 square feet.

FabricSpan LLC is an affiliated company recently located on the Dome Technology campus. FabricSpanä is a state-of-the-art air form manufacturing facility that designs, lays out, cuts and fabricates the intricate air forms incorpo-rated by Dome Technology to form the permanent roof membrane in each constructed dome.

By manufacturing FabricSpanä air forms next door to ES2 Engineering System Solutions and Dome Technol-ogy’s main facility, our combined team can better monitor and control the superior quality of the FabricSpanä air form. Visual and mechanical control methods ensure quality con-trol. Air form products are tracked from purchase of the fabric in Germany, through manufacture of the air form in Idaho, to their delivery at project sites around the world.

The cutting table is 20’ long with a cutting width of 102”. Proprietary soft-ware and fully automated head interchangers cut fabric to precise specifi-

cations.

The FIAB fabric welder runs the length of the 290’ welding

table allowing for large projects and timely completion. Radio fre-

quency and heat welding bind the polyvinyl, polypropylene and

polyethylene fabrics together.

CONSTRUCTION PROCESS

PHASE ONE: RINGBEAM

The ringbeam is a circu-lar foundation of rein-forced steel and concrete that will support the weight of the completed dome.

The continuous circular footing is extremely strong in bearing both compressive and sheer forces, and anchors the building through hurri-cane and tornado force winds, debris impact, and earth movement.

9

PHASE TWO: FABRICSPAN AIR FORM INFLATION

Huge fans inflate the air form to its engineered profile.

Air form after being unloaded off

Workers check air form holds as inflators blow air into the air form.

Rebar and construction equipment located inside ringbeam under air form before final attachment and inflation of the air form.

The FabricSpan air form is made from a

rugged multi-ply material similar to a

commercial roofing membrane. The air

form forms the permanent exterior roof

membrane of the completed dome struc-

ture. In some cases the air form may be

tiled or painted.

10

PHASE THREE: INSULATION

Once the air form is inflated, workers spray polyure-

thane foam insulation onto the inside of the air form.

This foam layer provides initial rigidity so initial mats of

rebar can be attached to the foam.

The insulating foam layer combines with the thermal

mass of the concrete dome to give domes their excep-

tional energy efficiency. By eliminating air penetration

and reducing the extreme outdoor air temperature fluc-

tuations on the concrete, the dome sustains a comfort-

able average temperature year around.

When heating or cooling inside the dome is necessary,

temperature ranges are smaller than a conventional

building. The time it takes to raise or lower temperatures

in dome compared to conventional structures is reduced;

therefore, the HVAC system does not work as hard or as

long and saves money on energy bills.

Below: workers applyin

11

PHASE FOUR: STEEL REINFORCEMENT

Rebar is staged inside the ringbeam perimeter

prior to inflation along with the cranes, man lifts

and other equipment that will be needed to hang

the rebar once the air form is inflated. Wire stick-

ers are mounted over the entire surface of the

sprayed on foam, and then secured with addi-

tional sprayed insulation. Rebar is then tied to the

stickers horizontally and vertically forming an

incredible spider web of steel.

Each dome is sized and engineered according to

our clients’ needs. The quantity and diameters of

rebar are engineered to maximize the required

performance of the dome taking into account the

height of the stem wall and distributed loads and

point loads of mechanical and sound systems,

lighting, catwalks, balconies, mezzanines, etc.

suspended from the dome. A dome can require

over 1 million pounds of rebar!

12

PHASE FIVE: SHOTCRETE

Once initial rebar mats are in place, workers begin spraying con-

crete (called shotcrete) onto the rebar and foam. Working in circles

from the bottom to the top, shotcrete is uniformly applied around

the dome in progressive layers and mats of rebar until the dome ac-

quires its pre-engineered thickness, is entirely self-supporting, and

able to bear incredible loads placed on its exterior or suspended

from its interior.

A properly engineered thin shell dome will have a much thicker ap-

plication of shotcrete and steel in the lower zone of the shell com-

pared to the middle and upper zones as the overall thickness gradu-

ally tapers to an application of shotcrete at the apex of the dome

than can be just a few inches thick.

The shotcrete acts as an efficient thermal mass that captures and

maintains ambient temperature and slowly radiates it back into the

space. Coupled with the natural airflow characteristics of a sphere,

this thermal mass helps keep temperatures relatively uniform and

constant throughout the dome.

DURABILITY—DOME VERSUS THE US AIR FORCE

WHAT WOULD HAPPEN IF THE U.S. AIR FORCE DROPPED A LASER-GUIDED

5,000 LB. BUNKER-BUSTER BOMB ON A DOME TECHNOLOGY DOME?

BAGHDAD, Iraq (AFPN) -- A member of the Combined Weapons Effectiveness Assessment Team assesses the impact of a precision-guided 5,000-pound bomb through the dome of one of Saddam Hussein's key regime buildings here. The impact point is one of up to 500 the team will assess in coming weeks. (U.S. Air Force photo by Master Sgt. Carla Kippes, 1st Combat Camera Squadron, 621st Air Mobility Operations Group)

WHAT WOULD HAPPEN?

NOT MUCH

This dome was built by a sister company in

Iraq using our patented thin shell dome con-

struction methods. The GBU-28 Deep Throat

5,000 lb. laser-guided bunker buster bomb ini-

tially punched a ―skylight‖ in the top of the

dome, but did little other damage to the dome

shell after it detonated inside, although it blew

out the doors and totally destroyed the interior

architectural features. The exposed twisted

metal hanging from the roof interior is not

dome rebar, but post-installed steel reinforcing

that once anchored the interior architectural

features.

LETTER OF RECOMMENDATION

Beggs Public Schools 1201 @ 9th Beggs, OK 74421 To Whom It May Concern: Beggs Public Schools in Beggs, Oklahoma recently had Dome Technology build two domes on our campus. After visiting some of the domes in Texas, our Board of Education was sold on the idea of the dome as classroom building and as our event center. People come from all over the nation to see them. They are wonderful. We recently looked at the past year’s savings in utilities in these buildings verses traditional style buildings of the same size. We have a dome classroom building of 10,000 square feet that cost $5500.00 for the 2006-2007 school year (12 months) to heat and cool. A metal classroom building of the same size cost $30,650.00 for the same year. Our Event Center Dome is 30,000 square feet. The cost for electric-ity for it during the 2006-2007 school year was $6,600.00 and another metal building of the same size cost $42,000.00 for that year. We are very pleased with our dome buildings. Dome Technology was great to work with during this whole building project. They are very knowledgeable about domes and building them. I would work with them again any time. Hopefully, we will be building more domes in the future with Dome Technology. Darryl Cunningham led the crew that built our domes and he is the best! You can trust him and he is a very hard worker. I recommend Dome Technology for the construction of any size dome for schools, homes or busi-nesses. Feel free to call me or email me any question you may have about our domes. Sincerely, Marsha Norman Superintendent mnorman@beggs.k12.ok.us W (918) 267-3629 H (918) 267-4053 C (918) 830-7695
