The design called for one-sided forming with concrete poured between the forms and a wall of shotecrete-treated earth. This surface pro‑ vided a relatively straight opposing wall and maintained support for the surrounding slab during construction. Similar to a cofferdam, the forms needed to be braced against the horizontal pressures on all four sides during concrete placement operations.

It was determined that the best forming system for this application was Max‑A‑Form. Its large panel sizes and smooth finish, com‑ bined with the strength of the system, made it a natural choice for this large, but confined application.
