From an Engineering News Record article on 8/23/2004 about hurricane Charlie: "In Punta Gorda, every school suffered extensive damage–except for the 900-student Sallie Jones Elementary School, a two-storey, 98,000-sq-ft, tilt-up concrete structure with metal roof, steel floor and roof framing. Reynolds, Smith and Hills, Inc., South Jacksonville, Fla., designed it in 2001 to meet the standard of 120 mph wind load. An additional "importance factor" of 1.15 resulted in a structural design load of 138 mph for wind."

		Tilt-up concrete construction offers unparalleled fire resistance. The image on the left says it all.
		This tilt-up concrete building was hit by a tornado. It suffered considerably less damage than its non tilt-up neighbours, which were leveled.
		Concrete is a long lasting construction material and avoids maintenance and damage problems associated with traditional construction systems.
