Complicated Footer Construction and Shop Drawing Headaches

We are done with the footer forms with the exception of adding all the rebar. There is a lot of rebar so we still have our work cut out for us but at least all the curved and overlapping form work is complete. Now we wait.... and wait.... oh and wait some more while the engineers go back and forth with the rebar supplier over the shop drawings.
We are delayed ordering our rebar by about 4 weeks and counting. Ordering rebar has turned into a series revisions. Shop drawings continue to be a way bigger deal than we anticipated. They had to be revised according to the engineers directions and ultimately need to be approved by the engineers. When I look at how everything has gone so far I can definitely point to the engineering part of this process as the biggest PITA...so far. Every time the engineers need to be consulted it means huge delays. I don't think it is our engineers specifically. I think it is the nature of building a house that needs specific engineering. Our case is worse than other dome builds due to having to hire two firms to get it done. If you want to go back and read my other posts about all our engineering woes click one of these MANY links to old posts or just go to the archive list. Some of the conversations I had with potential engineers were just as funny as my dealings with lenders. These links start from oldest to most recent.
It has turned into a HUGE hidden cost in building a dome. Normal houses don't need engineering so the cost is not comparable and something we didn't even know about going into this whole process. We thought the standard construction documents that you get from Monolithic were it. We originally had planned to have a garage/basement under the dome but had to give that up pretty early in the process once the engineers got involved. As soon as they started talking about cantilevers and prefab cement structural supports we knew it was going to be out of our price range. This is even more true since we couldn't get a normal construction loan like we could have if were building a traditionally constructed house.

After we received the first draft of shop drawings the engineers made a ton of changes. Our foundation ended up not being as complicated as they originally anticipated which is a good thing since we are stuck doing it ourselves. The shop drawings are made from the engineering drawings. Since the engineering drawings were way over the top they didn't reflect what was being built by us. Once we dug the hole and started building the footer it clearly didn't need all the step downs and very tall 7 ft walls that were originally in the engineered drawings. That doesn't mean it isn't complicated compared to all the other monolithic dome foundations I have found online in videos. All those people have had it super easy. Our footer varies in width from 2 feet to 6 feet wide. The biggest footer areas are under the edge of the cut away front. There are 6' x 10' pads under those walls.

Every other dome build I have watched on YouTube has a standard 2 foot footer all the way around regardless of it being multiple overlapping domes or just one big one. This is why Mr. Dometastic and I keep joking about it being a bridge or parking garage construction and not a house.

The list of reasons ours has been a hot mess right from the beginning
  1. We are forced to use an engineering firm that has never done this before because our town is requiring "stamped" engineering. Only a firm licensed in our state can do it and there aren't any firms experienced in this type of construction. 
  2. We got around #1 by hiring an engineer experienced in domes to do the engineering for the dome superstructure and then teach a local firm who would be the "engineer of record". This engineer is then the one who oversees the build and is responsible for the foundation part.
  3. Our build area is not flat so the foundation has to have "step downs" and the engineer has designed the footer for a parking garage not a house. Just kidding...sort of.
  4. We are building in Connecticut so a minimum frost wall depth of 42" is needed
  5. We are the ones building it and doing the general contracting. We don't know how it is supposed to go so we continue to be surprised by steps in the process. We ask as many questions as we can but have found that no one volunteers info. If you don't ask the right question you often find out there is a step in there that no one told you about. That hidden step then becomes a stumbling block that turns into delays because you couldn't plan for something you didn't know existed. 
Today we received another revision of the shop drawings that were missing things so back it goes for more revisions. Maybe we will be lucky and this is the final time and the engineers will give final approval. Each time they go back and forth is is another week of waiting! A few days to do the revision and a few days to review the revision......

Radiant Heat and Drywall DONE!

  We are DONE with dry wall and everything is painted!!! It looks almost like a real house inside. I can top that news by saying WE HAVE HEAT!!! Lets take a moment to celebrate having a functioning heating system in a cold climate in the middle of winter! The marathon of drywall is done for now. We still have the master wing of the house to do after we move in but we would like to just pretend we are done for awhile. It was a long slow dusty process but it looks amazing. The flat walls are a cool white and the dome surface is a warm cream. All our color will come from materials not paint colors. We have plans for wood, metal and stone throughout the house. We are finally getting to install more lighting fixtures and finalize all the outlets and switches. To watch a five minute video walk through CLICK HERE . Greatroom floor outlet in the center of the room. We decided that since the room is 32' across it needed an outlet in the center where furniture would be. Kids bathroom sconces...

Construction Video and Geodesic vs. Monolithic Domes

While we wait as patiently as possible for spring to dig holes for our new perc tests my posts will be directed towards general dome related things. Most people I talk to know what a dome home is but are clueless about the different types of domes. This post is to help show the differences between geodesic and monolithic domes with a few pictures of each. The saying "a picture is worth a thousand words" is true and a video must be worth 100000 words. (Watch a video of a monolithic dome being constructed at the end of this post to really wrap your mind around the process.) Many people have asked me how a monolithic dome is different than a geodesic dome. The answer can be quite simple. A monolithic dome structure is all one piece and geodesic domes are made up of many pieces (triangles) connected together. Monolithic domes are sprayed concrete like some inground pools. Here are some photos of interior and exterior monolithic domes. Compare the above Mon...

Spider Tie System Stem Wall Forms Complete

We finished building the stem wall forms last weekend! Personally I think they look super cool and I will be a bit sad to deconstruct them after we pour them. So much work to build them only to take them apart again and then just bury the whole thing underground. The original plan was to pour the stem wall on Friday October 11th but our weather was once again not cooperating. We are got yet another rain storm fueled by a storm/hurricane that thankfully mostly missed us. Because of this storm we are now scheduled to pour it on Monday October 14th. This was quite the ambitious DIY project for us. I can understand why we couldn't even get a company to put in a bid. Part of me is amazed that we pulled it off...so far. The truth will be in how it holds up to the concrete. It took almost 3000 screws to put the plywood skin on the Spider Tie towers and we cut 120 sheets of plywood! We joked that we were the Dometastic saw mill. Watch some videos of the process. It is...
