engineering student Diane Hartley contacted LeMessurier's office after she identified winds that could topple the building under certain circumstances. Later, another young student, Lee deCarolis, prompted LeMessurier to redo his analysis. He discovered that the contractor had replaced the required welded joints with lower-cost, and potentially weaker bolted joints.
