The DoD’s Defense Innovation Unit is spearheading a construction project – in conjunction with private entities – to build three training barracks using giant 3D printers. These 3D printed structures will each be 5,700 square feet, making them the three largest structures build by 3D printers in the western hemisphere.
Until now, 3D printed structures were not an option for DoD buildings as their “Unified Facilities Criteria did not include specifications for 3D-printed concrete wall systems,” according to a DoD press release. The newly released UFC included guidance for 3D printed, additive concrete construction, making this initiative the first of its kind for the DoD.
Commander of U.S. Army Installation Management Command, Army Lt. Gen. Doug Gabram, said “Constructing facilities using this cutting-edge technology saves labor costs, reduces planning time, and increases the speed of construction of future facilities.”
The DoD’s Structural Discipline Working Group intended the changes to the UFC to “enable and empower the technology transition led by the U.S. Army Engineer Research and Development Center and [the Defense Innovation Unit],” and to “leverage commercial innovation and incorporate novel, timesaving manufacturing methods within the DOD,” according to the Pentagon.
Gen. Gabram added, “We are looking at other ways to use this innovative technique for rapid construction of other types of facilities beyond barracks.”
The Austin, TX based construction technology company contracted to build the barracks, ICON, has provided 3D construction work for the Marine Corps in the past. in 2021, they worked with the Texas Military Department to build a smaller barracks in Bastrop, TX at the Camp Swift Training Center.
The material being used on the project is proprietary to ICON called Lavacrete. Aside from being higher strength than traditional concrete, it can withstand extreme weather, provide a higher level of protection to occupants from natural disasters, and reduces operating costs associated with temperature.
The project is projected to conclude in approximately 10 months.
