Site Works - 19th August
Laying bricks continued and we passed the 11th course on all piers. This means that the angle of embrace for the arches is now less than 52 degrees for the remainder of the arch. This will allow us to complete the brick slip portion of the arches and get going on the dome. The remainder of the brickwork will follow on over the next few days to its completed state.
The beam across the top of the site is part of a setting out methodology for the dome that we will be testing tomorrow. It replaces our initial idea to use a central pole. Once we have the system working correctly we will document it here.
