Steel frame construction seems relatively simple, comprising of only a few repeated steps and lots of pre-preparation, and may in the long run prove to be more strong and durable then the other methods.

The design works on carefully cutting small steel pipes to desired lengths, for us that would be 35 55cm pipes and 30 60cm pipes, in order to have enough to fully construct our desired dome. TO do this we will need an angle grinder and the necessary safety equipment in order to safely cut the pieces into the desired measurements.

The next stage is to flatten each side of the pipes, possibly about 2.5-3cm at each end, so that we will be able to connect them together properly and securely, to do this we could find and rent a press, however a hammer may suffice, although it may take a while to hammer down 115 pieces of steel pipe.

 The next stage is drilling to allow the connection of bolts, to which we could use a drill press to cut holes in the centre of each flattened end about 1cm down from the ends of the pipe. We must ensure that the hole is bigger than the bolt to allow for the pipes to curve slightly in order to form the dome shape, however not too big that the bolt may fall out or be insecure.
Lastly, we will need to use bolts in order to connect each piece of metal in the hexagonal formation that geodesic domes are constructed from, and secure with nuts to ensure that the bolt does not fall out
This process seems relatively simple, however my concern is that the cost of getting all the steel pipes and equipment to complete the task may be incredibly high, and the fact that the pre preparation of flattening and cutting each piece may take an immense amount of time. We will need to discuss this to determine whether this is the most suitable design to follow.
