Urban Infrastructure Construction
About:
In support of activities in Jersey City, NJ, RCC Construction Field Services was contracted to install a subsurface bio-sparge system consisting of nine (9) sparge wells, seven (7) vapor collection points and all associated process equipment. Control valves were placed at each wellhead prior to connection to the conveyance lines, which were connected in series with homeruns trenched to the treatment equipment. The vapor collection lines were manifolded at the treatment equipment location into one passive discharge stack. Individual control valves were added at the manifold to control air flow in each vapor collection tube.
Construction activities were coordinated with specific construction constraints including active bridge construction and demolition, an active railway right of way and active property access roadway. Additional considerations included subsurface gas, electric and water utility lines within the construction trenching locations.
RCC worked closely with the bridge construction/demolition contractors as well as the railroad to insure no operations were affected by the system installation. RCC also maintained access to the property during all installation activities while avoiding all subsurface utilities.
