Corona, California


We are pleased to be performing our first hydrocutter project in California, on the Santa Ana River in Corona. Slurry concrete diaphragm walls are being installed for scour protection of the BNSF Railroad Bridge piers and abutments, just downstream of the Prado Dam.

The walls surrounding the existing piers will be 3 feet thick and 32 to 47 feet deep. The bridge piers will be protected with pier nose extension cast-in-place walls up to 44 feet high and rest on a new steel pile foundation. For the bridge abutments, the walls will be 4 feet thick and 34 to 92 feet deep. The deeper walls will need to be constructed under the railroad bridge with just 25 feet of vertical clearance, offering a low-headroom challenge that we are uniquely qualified to tackle with our new Bauer Hydrocutter equipment.
