For a building of this size, the fixed or open the door costs of a tilt-up construction project (like the rental of a large crane, for example) make it more expensive than steel, even though concrete is usually a less expensive raw material.he fact that builders in earthquake-prone California now use tilt-up construction for 90% of their single-story commercial projects indicates that concrete buildings are cost-competitive and extremely durable. The intended use for a building will also influence whether steel or concrete is the best choice.
