Ground Breaking! (Footing Laying)
1. Determine hole placement, size & dig holes.
After the holes were dug, we tamped the bottom of them down flat. We measured most of the times but for best results you probably want to measure a lot more than we did.
2. Fabricate footing pieces.
Next came fabrication of the footing pieces. Rus picked up this massive hunk of sheet metal to make the custom plates. This was cut into smaller chunks and then bored out with a mag drill. The mag drill was an expensive tool, but since we are gearing up to do large scale metal fabrication, we thought of it as an important investment. Boring and cutting metal this thick is not for the faint of muscle, so if you don’t have special tools we recommend finding a local metal fabricator to help you out with this step.
3. Place anchors.
Choosing the existing concrete as the reference point, we positioned temporary scaffolding for the anchoring hardware to float in the wet cement solution.
4. Mix & pour concrete.
We then mixed concrete at a 1:4 ratio with aggregate in our cement mixer. It took about four big loads to fill the holes. Russell went to our local metal supply, “Neds” and found some big sonotube (heavy duty cardboard tube) that we could use to make the last four holes perfectly round. (the ones that were not adjacent to concrete) This process took us about 4-5 days.
