SLSCO has landed a potential $287M contract with the Customs and Border Protection and the U.S. Army Corps of Engineers to build two border wall structures in California.

CBP said Friday the company will build a 15-mile-long primary pedestrian replacement wall and a 14-mile secondary wall encompassing the U.S. Border Patrol‘s El Centro, San Diego and Yuma sectors.

The agency plans to allocate $156M for the first project to replace outdated designs with a 30-foot steel bollard platform and another $131M for the second project to install another fence using the same material.

Both walls are meant to increase USBP’s ability to thwart illegal border crossings and transnational criminal activities along the southern border.
