tilt up
ANDERSEN AIR FORCE BASE, Guam -- 554th REDHORSE Squadron members guide a concrete slab into place during the tilt-up constuction process. The tilt-up construction process has been around since the early 1900s. The 554th RHS discovered that the tilt-up construction method was the the best construction technique for Guam, and underwent training to become proficient in the area, bringing tilt-up construction to Andersen.
