Building the Substructure

The substructure is the supporting part of a bridge.  For this project there are five piers and, of course, two abutments.  The piers will be built first.  This process is usually: build a cofferdam and pump the water out, drive the piling, pour the footing, pour the column, and pour the pier cap.
