After 9/11, the U.S. Army Corps of Engineers, for the Department of Homeland Security, hired Sundt to construct approximately 100 miles of 15-foot-tall fence in the remote deserts of Arizona and California to secure the border between the United States and Mexico. Sundt’s border fence work was among the first, largest and fastest to be built on the U.S.-Mexico border. Successful execution of our 10 border fence projects required tremendous precision and control in the face of challenges posed by international laws, remoteness of the site, extreme heat, supply scarcity and more.

 

Most of the fence consists of four-inch-diameter sections of pipe filled with concrete, spaced four inches apart. At the time of construction, the demand for steel was at an all-time high in the Southwest, so steel fabricators were already working at full capacity. For some sections of fence we had to employ several separate steel fabrication plants to achieve the level of supply necessary to complete the project on time. Extensive coordination ensured that the precise quantity of materials was delivered to the jobsite each day, since there was no way to store excess supplies in the remote location.

 

Crews could not occupy land on the Mexican side of the fence during construction, so they developed a way to erect the fence from one side only – in the two-foot space between the fence and the international border. Sundt’s innovative approach allowed all trenching, fence installation, temporary bracing, placement of footing concrete and final grading to be performed from the U.S. side, and at an accelerated pace.
