Fast-Form Systems Ltd were specified to construct 19 no-holding-down bolt boxes for test erection of the new flexible seating conversion to a football stadium for West Ham Utd.

The seating is removable and re-configures for athletics and ranges in sizes from 1.3m x 1.3m x .9m deep to 3.9m x.1.9m x .9m deep.

Fast-Form used timber rails to extend the centres of the brackets to reduce the number of brackets per base. They also tested smaller brackets strength by extending their height with 4 x 2 so a 600mm high bracket poured a 900mm high base proving the bracket can take much more than its own height in pressure. Normally ply would be applied directly to the brackets with no timber rails but at closer centres.
