Barrier Fence Along U.S. Border

Project Description

  • Client: 
    U.S. Army Corps of Engineers, Los Angeles District and the Department of Homeland Security
  • Location: 
    Arizona and California

Benham teamed with Granite Construction on a DesignBuildSM project for U.S. Army Corps of Engineers, Los Angeles District and the Department of Homeland Security to construct primary border barrier fence in Arizona and California. Benham provided the complete civil engineering, structural engineering and analysis, and hydraulic analysis and design for the border fence to meet Army Corps of Engineers, International Border and Water Commission (IBWC) requirements in the U.S. and Mexico, Federal Emergency Management Agency (FEMA), U.S. Border Patrol, and U.S. Bureau of Land Management requirements.

Benham provided services for:

 Hydrological analysis and design of the contributing drainage basins
 Structural design of the fence
 Coordination with various regulatory agencies
 Plan and design analysis document production
 Development of the operation and maintenance (O&M) manual for fence maintenance

The structural design of the fence included considerations such as vehicle impact load, wind load, seismic loads, and the effects of dune sand. The primary fence was typically constructed three feet north of the border except at monument locations.

The seven projects completed include:

 Moment 250 A1: in San Diego County, Calif., 5.2 miles of fence, 7.12 miles of roadway
 Yuma C-1: Imperial County, Calif., 10.40 miles of fence
