  • Infrastructure Innovation: New Poe Lock arrestor arm is the largest U.S. civil works component produced by 3D printer

    As America’s civil works infrastructure ages, managers need innovative solutions to replace parts that have been in service for nearly a century. Often, these original components were fabricated using vintage material and manufacturing methods, making them costly, burdensome and time-consuming to replace. Responding to this need, the U.S. Army Corps of Engineers (USACE) is employing cutting-edge 3D-printing techniques to manufacture these parts faster and at a lower cost while maintaining, and even improving, their properties.

  • Infrastructure Innovation: New Poe Lock arrestor arm is the largest U.S. civil works component produced by 3D printer

    As America’s civil works infrastructure ages, managers need innovative solutions to replace parts that have been in service for nearly a century. Often, these original components were fabricated using vintage material and manufacturing methods, making them costly, burdensome and time-consuming to replace. Responding to this need, the U.S. Army Corps of Engineers (USACE) is employing cutting-edge 3D printing techniques to manufacture these parts faster and at a lower cost while maintaining, and even improving, their properties. In early March, the USACE Detroit District installed the largest U.S. civil works infrastructure component produced by a 3D printer – a 12-foot-long metal part for the ship arrestor system on the Poe Lock, one of the two active locks on the Soo Locks facility. Building on years of research performed by the U.S. Army Engineer Research and Development Center (ERDC), the part was manufactured in 12 weeks, compared to a projected 18-month lead time for conventional manufacturing. The part was installed, tested and commissioned during the Soo Locks’ winter maintenance cycle. The rapid repair ensured normal operations at Poe Lock, a major transit point for domestic iron ore.

  • ERDC-Vicksburg laboratories celebrate 25th anniversary with Open House

    Laboratories from across the U.S. Army Engineer Research and Development Center (ERDC) showcased their expertise, experiments and research as part of a celebration honoring the agency's 25th anniversary.

  • Engineering Science in Okinawa

    It’s not uncommon to find members of the U.S. Army Corps of Engineers (USACE) interacting with students in a school setting. This is part of the USACE science, technology, engineering, and math (STEM) initiative, worldwide. Overseas in Japan, one would think you could find America’s Engineers working together with children at any number of Department of Defense Education Activity (DoDEA) schools as well, and they are. Engineers from the USACE’s Japan Engineer District work directly with DoDEA students and classes, promoting STEM and engineering in general.

  • ITL gains new high-performance computing system

    A new supercomputer will soon call the U.S. Army Engineer Research and Development Center (ERDC) Information Technology Laboratory (ITL) home. The system will support the Department of Defense (DOD) science and technology, test and evaluation and acquisition engineering communities and will significantly enhance ERDC’s ability to support the DOD’s most demanding computational challenges.

  • Surveying the Future

    Survey technicians, cartographic technicians and unmanned aerial vehicles (UAV) pilots are the boots on the ground for the New York District when it comes to collecting the critical information required by engineers, project planners, and real estate specialists. The Survey Section of the New York District resides within the Operations Support Branch of Operations Division. The teams workload comes from every office in the District when there’s a need for geospatial mapping support. On any given day survey teams are in the field collecting hydrographic and topographic maps to support the delivery of the district’s civil works, military and interagency and international support missions.

  • Savannah District paints a clear picture of the Savannah River bottom with sonar mapping technology

    SAVANNAH, Ga. – Every year, more than six-million visitors travel to walk the cobblestone steps of River Street in historic, downtown Savannah, Ga. An unobstructed view of the Savannah River offers visitors the unique opportunity of viewing some of the largest cargo ships in the world as they pass by under the Talmadge Memorial Bridge on their way to the Georgia Ports Authority’s Garden City Terminal. What they don’t see through the dark water under the passing ships, however, is the 47-feet deep river channel bottom, recently deepened and annually maintained by the U.S. Army Corps of Engineers, Savannah District.

  • Modernizing hydropower on the Snake River

    Hydropower, a clean, renewable and reliable energy source, just became safer for fish and more efficient at generating electricity, thanks to the new turbines at Ice Harbor Lock and Dam on the Snake River in southeast Washington.

  • USACE summit touts innovation as key to future development

    The 2021 U.S. Army Corps of Engineers (USACE) Innovation Summit was conducted virtually, October 25-29.

  • Autonomous Transport Innovation: A Review of Enabling Technologies

    Purpose: This document is the first of the technical note series under the Autonomous Transport Innovation (ATI) research program. The series intends to be an introduction on autonomous vehicles (AVs), their testing, and associated infrastructure. A review of technologies that enable vehicle autonomy is necessary to provide the basis for understanding vehicle performance in testing scenarios and in actual use.
