Figure 9. Shuttering boards are fixed to the frame and to each other.
As described earlier, the shuttering goes up in 600mm lifts on the side where people are
working to fill it, but on the other side it can be created from full boards. In the case of a
central frame, however, full boards are much harder to put up, since they are heavier and
therefore more difficult to manhandle and to hold in place while the fixings are going in.
They have the added disadvantage that they require three rows of fixings, and - while this
means fewer fixings overall, compared to two half-sized boards with two rows of fixings
each - the bottom two rows of fixings are hard to fit, because it's impossible to reach
around a full board to hold the spacers in place. Therefore one person needs to be posi-
tioned on the other side of the wall with the spacers, so that when the screw is started
through the board, they can hold the spacer in place and guide the screw to the correct
place on the frame as it is driven in.
