The U.S. Military Corps of Engineers (USACE) and the Naval Services Engineering Methods Command (NAVFAC) outlined how superior development applied sciences—from 3D printing and mass timber to high-performance concrete—are reshaping army infrastructure throughout a Capitol Hill briefing this week.
The dialogue lined a variety of strategies, together with additive development, high-performance cement and concrete mixes, geosynthetics, mass timber, composite supplies, industrialized development, pressure cloth buildings, and carbon fiber–strengthened polymers. Lawmakers heard how these improvements may make future army services extra cost-efficient, resilient, and sustainable.
“In an more and more advanced international safety setting, our dedication to innovation in army development is not only about constructing buildings, it’s about constructing the resilience and readiness our forces must prevail,” mentioned Dave Morrow, director of army applications for the U.S. Military Corps of Engineers. “By working with business to leverage these developments, we will ship extra sturdy, sustainable, and cost-effective infrastructure for our army, making certain taxpayer {dollars} are used effectively, whereas equipping our troops with one of the best services on this planet.”
3D Printing for Quicker, Smarter Building
Morrow highlighted how USACE is advancing additive development—3D printing of buildings—by means of pilot tasks at Tyndall Air Drive Base in Florida and Fort Bliss, Texas. At Fort Bliss, three new barracks have been accomplished utilizing 3D printing, demonstrating how the strategy will be deployed each in garrison and expeditionary environments.
“Additive development has [the] potential to scale back prices, manpower, logistics and time, whereas opening the door for improved and new functions, resembling unconventional countermeasures,” Morrow informed lawmakers.
To allow wider implementation, USACE’s Engineer Analysis and Improvement Middle helped set up unified services standards permitting additive development in 80% of the USA. These requirements outline the technical necessities needed to make sure code-compliant, protected, and useful army services, he mentioned.
Increasing Use of Superior Supplies
Past 3D printing, each USACE and NAVFAC are testing new supplies geared toward enhancing sturdiness, sustainability, and effectivity in army development.
In Hampton Roads, Virginia, the Navy is piloting the usage of mass timber—also called cross-laminated timber (CLT)—for a brand new baby improvement middle, mentioned Keith Hamilton, NAVFAC’s chief engineer. In written testimony, he famous that the ability will characteristic “a hybrid mass timber exterior envelope consisting of cross-laminated partitions and diaphragms.”
“DOD has expressly acknowledged the applicability of CLT with the creation of a information specification,” Hamilton mentioned. “Because the CLT development business matures, CLT might show extra aggressive and might be utilized extra broadly in DOD development.”
USACE can also be exploring mass timber functions. “We not too long ago designed the Military’s first barracks made primarily with mass timber structural components and are soliciting curiosity in development of a mission at Mountain Dwelling Air Drive Base, calling for the incorporation of mass timber design,” Morrow mentioned, noting that the strategy may assist shorten development timelines.
At Marine Corps Air Station Cherry Level, North Carolina, NAVFAC has been testing high-performance concrete (HPC) for a brand new F-35 Lightning II hangar, Hamilton mentioned. The fabric provides enhanced sturdiness, energy, and resistance to excessive situations, together with improved thermal and acoustic efficiency.
“HPC has been used extensively for our piers, runways and different essential infrastructure; and we’re broadening its software,” Hamilton wrote in his testimony.
Hamilton added that NAVFAC continues to collaborate with USACE, business, and academia to speed up adoption of modern development strategies. “NAVFAC is actively testing and using modern applied sciences, supplies and strategies for design and development as we speak, and we’re leaning ahead to extend collaboration with business, academia and different authorities companions to establish and leverage future alternatives,” he mentioned.
Building 3D printing for army
Just lately, Texan firm collaborated with the U.S. authorities-backed Protection Innovation Unit (DIU) to check the army functions of 3D printing at Camp Pendleton Marine base. A group of eight Marines, with little engineering expertise, skilled on ICON’s Vulcan 3D printer and efficiently constructed a automobile conceal construction in 36 hours. Measuring 26 toes lengthy, 13 toes vast, and 15 toes excessive, the construction was created utilizing Lavacrete materials. Following the profitable take a look at, the know-how continued for use in broader U.S. army operations.
Elsewhere in 2023, the Indian Military accomplished its first 3D printed dwelling unit in Ahmedabad Cantonment, designed to be disaster-resistant and compliant with Zone-3 earthquake specs and inexperienced constructing requirements. Constructed by the Army Engineering Companies (MES) in aliance with Gujarat-based MiCoB Pvt Ltd, the 71-square-meter construction, together with storage area, was constructed utilizing 3D Speedy Building Expertise.
The method concerned printing partitions, slabs, and the inspiration, decreasing the development time to 12 weeks. On the time of this announcement, it was revealed that the military was additionally testing 3D printed precast defenses and overhead safety buildings, together with in Ladakh, for potential operational deployment.
