The Department of Defense, specifically the U.S. Army Corps of Engineers (USACE) Engineer Research and Development Center (ERDC), is seeking qualified contractors to establish multiple Master Blanket Purchase Agreements (BPAs) for Horizontal Directional Drilling (HDD) and installation services of underground fiber optic cable along the Southwest U.S. border, covering states such as California, Arizona, New Mexico, and Texas. The procurement involves drilling tunnels beneath various terrains, including concrete and riverbeds, and requires the installation of conduits, slurry removal, and documentation of as-builts, with a performance period of one year and the option to extend for up to four additional years. This initiative is critical for enhancing fiber optic infrastructure, ensuring compliance with federal security protocols, and maintaining safety standards throughout the project. Interested parties must submit their quotes and technical documentation by 1:00 PM Central Time on May 23, 2025, to the designated contacts, Jon-Vincent Holden and David Ammermann, with an estimated total capacity of $243,750 over the five-year period.
