Before beginning design, the engineer should work with the contractor to figure the total cost of various available sizes and types of cranes. Other design considerations: use a rectangular layout; keep architectural features simple; minimize the wall thickness; pay attention to joints, seals and connection details; provide egress for the mobile crane. This article offers illustrations and tips on designing and constructing a typical 32x200-foot tilt-up mini storage facility. These are general techniques and examples. Any tilt-up building should be analyzed and designed by professional engineers or architects familiar with the tilt-up method.
