Throwback: The world’s oldest monolithic dome — the Pantheon

The entrance to the Pantheon in Rome, Italy.

The Pantheon is arguably the first monolithic dome. Not in the sense of the modern, insulated structure, but as the original one-piece, monolithic, concrete dome — the largest unreinforced concrete dome in the world. No other significant structure of antiquity has survived as well preserved nor with the roof intact.

Central City to build Nebraska’s first Monolithic Dome gymnasium

Gymnasium interior rendering

Central City Public Schools is constructing the first Monolithic Dome gymnasium in Nebraska. When the dome is opened in August 2020, it will seat 2,500 spectators and shelter over 3,000 people during severe weather. The facility is years in the making and it started with a simple internet search.

Throwback: Houston area church is a dome of many firsts

Flying over the job site reveals the scope of work.

Today’s throwback story is from 1984 with a dome of firsts — the Maranatha Church — the first Monolithic Dome over 200-feet diameter, the first dome proving energy savings enough to pay for the building, and the first high capacity auditorium with seating for over 4,000.

The South’s say goodbye to the South Sawmill Lodge

South Sawmill Lodge

It’s time to say goodbye to the South Sawmill Lodge. Randy South’s family of South Industries started the 90-foot diameter dome in 2009 on the old family homestead in Island Park, Idaho. Over the next four years, the family squeezed in time to finish the dome which became a lodge and reunion center rented out to dozens of families over the years. The lodge sold this spring.

The easy way to calculate a dry bulk storage dome

Medium product storage dome.

How big is a Monolithic Dome that stores 10,000 tons of ammonium nitrate? Or 750,000 bushels of corn? Or 34,000 metric tonnes of gypsum? These are straightforward questions without quick answers — until now.

The dome builder workshops are back!

Workshop alumni after building a Monolithic Dome.

It’s back! After a year and a half hiatus, the Monolithic Dome Builders Workshop resumes again in September 2021. Coronavirus restrictions are lifting. Travel is returning. We can finally gather to teach, discuss, and build another Monolithic Dome.

Over the edge with vertical ellipsoids

Sketch of the concepts used in the vertical ellipsoid dome calculator

Inflatable shapes are the basic components of Monolithic Dome design. If it inflates, it can be constructed … probably. There are two primary shapes that dominate dome design — the sphere and half-ellipsoid. However, these are not the whole design palette. Sometimes we need to go beyond the basics. or in this case, beyond half of the ellipsoid.

Rare winter storm wreaks havoc in Texas

Winter snow covering Monolithic Dome Research Park near Italy, Texas

Monolithic Domes are amazing. The insulation, coupled with the concrete’s thermal mass, creates an atmosphere that is hard to describe. Simply put, it feels the same today as it does in the middle of summer. If you set the thermostat at 70 (21°C), it just stays there. During the two-degree, 24 hour period, my heater ran for a total of 9 hours. This is a small heater, with only 30,000 BTUs. Most homes the size of mine have 100,000 BTU heaters, but even my neighbors with electricity struggled to stay warm with heaters running nearly 24/7.

Refactoring the ellipsoid calculator

Sketch of ellipsoid dome calculator concepts

Circles and spheres are easy to measure. Calculating a spherical dome’s floor area, surface area, perimeter, and volume are straightforward mathematical formulas. When I wrote the new Spherical Dome Calculator, the challenge was the scaled drawing, not the computed values. Ellipsoids — on the other hand — are hard.

Another workshop canceled due to the coronavirus

Workshop canceled again

We are a year into the pandemic and although the daily news is bad, we have every reason to hope. Two vaccines are approved and more are coming. With every person vaccinated we inch closer to a return to some form of normal life. Patience is required. We would love to start holding the Monolithic Dome Builders Workshop again, but it’s not yet time. For the sake of our customers and staff, the Spring 2021 Monolithic Dome Builders Workshop is canceled.

TBT: Design inspiration in a frozen hotel

Art Suite at Ice Hotel in Sweden

In today’s Throwback Thursday we revisit the Ice Hotel — 200 km north of the Arctic Circle in Sweden. This unique hotel is built and rebuilt every winter using ice, snow, and a lot of creativity. It’s a masterpiece of design and an inspiration for curved architecture elements that could be built — permanently — using a Monolithic Dome.

David Barney South, 1939-2020

We are sad to announce the passing of David Barney South Sr. — husband, father, entrepreneur, and inventor.

TBT: The past and future Johnson Creek School

Aerial view of construction

Today’s Throwback Thursday is a bit different as we look to the past and the future in Johnson Creek, Wisconsin. In 2016 the Johnson Creek School District opened a five-dome school to serve as the combined middle and high school. The small district of 750 students was dealing with old school buildings plus a hodgepodge of additions and portable classrooms. The maintenance costs were increasing and they needed something new. They tried several times to pass a bond to build a conventional school, but each time the voters rejected it. So they sought for a more innovative, affordable solution and found the Monolithic Dome.

The story of a Hawaiian dream home — now for sale

Whoever buys Jo King’s Hawaiian dome will buy so much more than a home. They’re buying a dream. The dome has a lot to offer, starting with breath-taking views. Snuggled on an acre of land in the Waimea Valley on Kauai, it’s surrounded by an abundance of history and natural beauty. The open floor plan offers two bedrooms and two and a half baths upstairs with another bath as well as two outdoor showers downstairs, all covering about 1,700 square feet. Painted coconut palms adorn the concrete walls, and a large lanai takes full advantage of the scenery.

Monolithic Dome workshop graduation photo

We live with hope for a better future, yet, we need to recognize the realities of today. COVID-19 cases are surging in Texas and across the US. There is no reason to believe the coronavirus pandemic will end anytime soon. We must accept that this is our new “normal” and plan accordingly. To that end, we are canceling the Fall 2020 Monolithic Dome Builders Workshop.

TBT: The Lincoln County Farm Center

Today’s Throwback Thursday is the Lincoln County Farm Center on US Route 66 in Chandler, Oklahoma. It’s home to the first Monolithic Dome fertilizer storage project — built more than 40 years ago in 1978. In 2011, the storage dome was covered with stainless steel and in 2015 they built a large, Monolithic Dome ranch store.

Delaware Military Academy: Fulfilling their mission in a Monolithic Dome

Located in Wilmington, Delaware, the Delaware Military Academy is home to the first Monolithic Dome of its kind in the Mid Atlantic United States. With over 500 young cadets attending the school, the dome has opened up new opportunities for the cadets. The administration of the academy has expressed gratitude for the many benefits of a Monolithic Dome, and the cooperation and generosity of those involved to make the project completion possible.

Monolithic Dome industry response to COVID-19

We’re all in this together

After receiving so many COVID-19 related emails — some from companies we haven’t dealt with since the early 2000s — we feel it’s time to discuss how COVID-19 is impacting the Monolithic Dome industry. But first, we want to thank you.

The ‘Texas Bucket List’ to feature Monolithic Dome Research Park in Italy, Texas

This week, The Texas Bucket List is featuring the Monolithic Dome Research Park on their weekly, syndicated television program. Entering its fourteenth season of “sharing the joy, wonder, beauty and excitement of Texas,” host Shane McAuliffe interviews Gary Clark and tours the Monolithic Domes in Italy, Texas. It’s fun to be profiled by a Texas program, after all, the 240-foot long caterpillar shaped manufacturing plant — Bruco: The Texas Italian Caterpillar — is an iconic landmark on Interstate 35E.

Spring 2020 Workshop is CANCELED

The Spring 2020 Monolithic Dome Builders Workshop is canceled due to the Coronavirus (COVID-19). Everyone who signed up will receive a full refund. There are persuasive arguments that we should be proactive in limiting the spread of the virus. We can either voluntarily choose to sacrifice events and travel now, or the virus will likely force painful restrictions in the future. We choose the former for the sake of our workshop attendees and our staff. Hopefully, if we all work together, we can host the Fall 2020 Workshop in September. Thank you to everyone who signed up. We also thank everyone for fighting this pandemic and pray for those suffering from it — may they receive the care they need and recover quickly.

The Hennessey superintendent said, “I want to build a dome.”

Before the sun came up on a cold December morning, the crew turned on the four large blowers that were to inflate the structure. They said it should take about three hours to completely inflate, which gave my team plenty of time to set up the four time-lapse cameras, a drone, and several ground video cameras. Next thing we knew, the roof was up within minutes, including that big heavy ring. We were not ready! Think about this, an entire weather-sealed, full-size gymnasium was completely standing in about 45 minutes!

Monolithic granted patent for Transverse Airform pattern

Inside a Transverse Airform

The offer for a commemorative plaque always arrives first when a patent is granted. The plaque company usually beats the patent office by a day or two. It’s an effective marketing strategy; after all, Monolithic has five of these plaques. Now there will be six. A couple of days later, the official notice from the United States Patent and Trademark office arrives. Monolithic Constructors, Inc., is granted patent number 10,400,462 for the “Transverse Span Airform Structure.”

Ohio opens first tornado shelter at Delaware State Park

Delaware State Park Tornado Shelter

Ohio is probably not the first State people think of when discussing tornadoes. Oklahoma or Kansas are more likely to provoke visions of violent skies and Dorothy running for the storm cellar. Yet, 36 tornadoes already struck Ohio this year — double the total tornadoes in 2018. “We are not dealing with a theoretical hazard,” said Sean Miller at the open house of the new Delaware State Park Tornado Shelter. “This is a very realistic hazard … and campers are vulnerable.”

The “spaceship” house for sale again in Colorado

Back porch

Architect Jason Elliott Purdy designed the “spaceship” house for Clarence and Louise Lederhos who constructed the dome in 1978. “For some reason, I always wanted to live in a round house,” said Louise Lederhos in an interview. “But it was the energy efficiency that drew us to this design.” In 2016, they sold their home. Today, it’s on the market again.

Engineering.com article calls for buildings to survive after disasters

Eye of the Storm dome home

A building must do more than stand during a disaster. It must be useful afterward. Water infiltration and other issues can render a still-standing structure useless. Emily Pollock digs into this issue in her Engineering.com article, Outside In: Designing Building Envelopes to Withstand Climate Change.

Animals—and people—sheltered in dome during Hurricane Michael

Main entrance

Forecasts predicted Hurricane Michael would land in Panama City as a strong, but still manageable, Category 3 hurricane. Employees of the Humane Society of Bay County — along with their families, friends, cats, and dogs — spent the day preparing to ride out the hurricane under the protection of their Monolithic Dome. As everyone settled in for the night, no one expected anything too severe. Then Hurricane Michael intensified into the strongest hurricane to ever hit the Florida panhandle.
