PRIME was contracted by the U.S. Army Corps of Engineers (USACE), Fort Worth District to provide engineering support to Customs and Border Protection’s (CBP) Border Patrol Facilities and Tactical Infrastructure (BPFTI) Program Management Office (PMO) relative to their Tactical Infrastructure on the southern international border including the Tucson Sector of the U.S. Border Patrol (USBP). The purpose of this Task Order is to support the U.S. Border Patrol in Nogales, Arizona by providing design for the all-weather roadway and low water crossings.

During the installation of PF225 pedestrian fencing, construction roads were created to allow access necessary for the heavy machinery required to construct the fencing. These roads were intended to be temporary and were not constructed to a standard suitable for long term use. PRIME designed approximately 2,400 feet of all weather roadway along the southern international border between the United States and Mexico. The project begins 4.6 miles east of the DeConcini Land Port of Entry in Nogales and continues east through the Coronado National Forest. The project site is very rugged and mountainous.

The project also involved design of road side drainage ditches, cement stabilized aggregate base course (ABC), culvert headwalls, and articulated concrete matting for two low water crossings in the project area. PRIME used Technical Manual TM 5-822-12, Design of Aggregate Surfaced Roads and Airfields and the Tactical Infrastructure Design Guideline in the design of the all weather roadway, ditches, and low water crossings. PRIME also performed a hydrologic/hydraulic analysis which included delineating of the drainage basins, calculating the drainage runoff for the 100-year storm event, and determining the impact of the new roadway to the natural flow. PRIME prepared construction drawings, Bill of Material (BOM) packages for military deployment phased with proposed deployments and that are compatible with the Mission Essential Task List (METL).
