When Dukane Precast, of Naperville, Ill., contracted with the UPS to create a precast structure large enough to hold 25 football fields, they knew they would need new forms, more equipment and a larger facility to handle the job. The UPS hub will use more than 2,600 loadbearing wall panels and 700,000 square feet of precast/prestressed concrete panels. The facility will have mroe than 1.8 million square feet under one roof. In order to complete this project, Dukane had to increase its work force and build a 425-foot-long, 65-foot-wide plant prefab metal building, housing two 12-foot-wide, 320-foot-long casting beds. The facility features state-of-the-art computerized temperature monitoring systems.
