The Border Fence project DV-3 is located within the Area of Operation of the Office of Border Patrol’s Tucson Sector, Ajo and Casa Grande Stations and traverses approximately 10.83 miles along the International Boundary between the United States and Mexico, in Pima County, Arizona.
The project consists of installing 10.40 miles of VF-1 fence (post-onrail) and approximately 0.43 miles of VF-2 fence (normandy) and all components necessary to complete the construction, including clearing and grubbing, labor and equipment. Because the project was on the Tohono O’odham Indian Reservation (TON), tribal monitors were required for all earth moving operations along with coordination and collaboration with landowners.
A major portion of work involved processing more than 31,261 tons of lead-contaminated soil and treatment and disposal of additional 38,137 tons. Straub and its remediation subcontractor developed an alternate treatment plan that involved the encapsulation of low lead-bearing processed soils, processing and removal of high lead-bearing soils and protection of clean soils located outside the construction area.
Straub Construction served as the Prime Contractor for this project being responsible for all contract activities including partial design. The company self-performed: project management including preparation and control of the construction schedule; quality control and safety management including development and implementation of project specific plans, performance of inspections, directing of rework activities and providing regular safety training; preparation of submittals, as-built drawings, regular status reports and O&M manuals; and, contract administration. Straub also performed approximately 14% of the construction including: demolition; rough and finish carpentry; caulking and sealants; and, punch list items.
