This project consisted of replacing three existing high security subsurface wedge barriers with rated above ground drop-arm beam barricades. The barriers were installed at three locations around the facility. The barriers are capable of local and remote activation and remote operation integrated into the existing security monitoring/alarm/notification system. Two of the barriers spanned a standard two land roadway and on spanned a one lane access road. Site Work Solutions was responsible for the design-build-installation aspect of the three barriers. Site Work Solutions decommissioned and removed the existing inground wedge barrier system. Restoration of the roadway surface was completed after the installation of the new barriers.
