Monsanto contracted with Hayden Wrecking to demolish dryers that were supporting conveyors at their facility in Boone. IA. The schedule required the completion of the project prior to the beginning of the grain harvest in August. The dryers were located adjacent to equipment and structures which were to remain in place. Hayden Wrecking trained demolition craftsmen utilized manlifts and cutting torches to selectively dismantle structural components on the dryer in order to separate it from the structures to remain. The crew also removed the conveyors from the dryers so that they could be reinstalled. An Ultra High Demolition Excavator equipped with a rotating shear and concrete processor was utilized to dismantle the dryers. After completion of the dryer demolition and cleanup Hayden Wrecking subcontracted the fabrication and erection of structural steel to support the conveyors. The subcontractor then reinstalled the conveyors to complete the project.
