Site Works - 28 July
Our First day on Site!The site was set out, and after prolonged, occasionally heated, but always intelligent discussion a final location was fixed, at an angle to the field, and holding the edge of the route down to the site.
The centre of the site is to be marked with a central steel pole. This pole allows us to coordinate all set outs on site throughout the job as radii to this central point.
Ryan Kennihan dug the hole for the post, which was raised, plumbed and cast in concrete.
Once the concrete had set we could set out the site and commence digging the pads.
There are 4 pads, one at each corner of the dome. These are 900 x 900 x 300 concrete over 200 compacted hardcore. These pads are connected by tie bars which act to counteract the lateral forces from the dome.
