The U.S. Department of Defense is constructing three barracks at the Camp Swift Training Center in Bastrop, Texas that will each be the largest 3D-printed structures in the Americas.
Each building will be larger than 5,700 sf and the project is expected to be completed within 10 months. Army brass say the 3D building technique saves labor costs, reduces planning time, and increases the speed of construction.
The buildings will be the first 3D-printed structures that comply with new DOD Unified Facilities Criteria for additive concrete construction. The Unified Facilities Criteria did not previously include specifications for 3D-printed concrete wall systems.
Until the new rules went into effect, companies that used 3D printing could not bid on DOD construction projects. The material used in the construction is ICON’s proprietary Lavacrete, which is a type of high-strength concrete with a compressive strength of 2,000 to 3,500 pounds per square inch, according to ICON. Lavacrete can withstand extreme weather and greatly reduce the impact of natural disasters, DOD says.
