Eagle Rock Aggregate Storage Facility
Langan provided geotechnical consultation and observation and testing services during the construction of the aggregate storage facility at the Port of Richmond. The new facility included a large storage building to house several stockpiles of aggregate material, and a conveyor system to transport aggregate from ships to the storage building and from the storage building to a hopper system for loading trucks with aggregate. The new storage building is supported on spread footings that bear on a layer of compacted fill over soil that has been improved using jet-grouted soil-cement columns. The conveyor and hopper systems are supported on deep foundations consisting of driven precast, prestressed concrete piles.
