It has nine piers built into the riverbed over a concrete sill, and there are huge cylindrical steel gates that rotate up between the piers to create a barrier against the incoming tide and keep the river level safe upstream. When they aren’t needed, the gates are rotated. In addition the sill scal‐lop surface must be positioned so that it does not interfere with the free movement of the gate.

The space available between the end of the sill and the pier is required to be within 55 mm and mm, which is extremely small in the con‐text of placing a 6l m long sill.
