We designed the formwork to be easily removable, first dropping the edges from underneath and then pulling away both sides in turn.
As we dropped the formwork it became clear that there was a major problem with the arch, as it dropped with the formwork, eventually completely buckling to one side.
We cleaned up the site, and managed to salvage most of the bricks. Our instinct is that the geometry of the arch is wrong, being too upright where it bears on the pads. We also feel that there were errors in our construction methodology with not enough overlap between the first and second courses of the arch.
Tonight we are going to have a design workshop with Michael Ramage to adjust the design to solve these issues. We meet tomorrow morning to adjust the formwork and begin again.
