Hayward Baker worked on a sheet pile & helical pile installation in restricted access conditions in a busy petrochemical facility. The client added a new sump area and needed to support the new concrete sump floor. Along with the new addition, the client also required deep foundation support of new pipe bridges and supports and retrofitting existing supports (concrete bell piers) with new helical piles in the main corridor of the facility. The subsurface soils generally consisted of lean-to fat clays in loose to medium soils 20 to 30 ft deep.

Robinson Landing is a $185 million, mixed-use development that covers a full city block on the Potomac River waterfront in Alexandria, VA. Despite the challenges of working on the Potomac River adjacent to historic buildings, Hayward Baker constructed a watertight TRD earth retention system on time and with minimal movement.
