	These bolts are a good high strength steel meant for steel construction that can undergo more than just tensile or shearing forces, like vibrations through use (think of bridges) or environment (wind).

	* Note: There are two systems! HR (UK) and HV (Germany) - we try to use the HV System! It should be stamped on the bolt's head.

	The dome was anchored with relatively small rebar anchors in the fears that it will fly away. There is no possible scenario in which the dome will fly off in strong winds. If that were to happen we will likely be dead by then. To prevent this the anchors needed would be those 50-100cm massive pegs for big festival tents, not the tiny things that were used. Adding those tiny anchors just makes teardown more difficult and serves no practical purpose. I'm not running any simulations to prove that I'm right but I also suspect that there is no data to prove that anchors are needed.
