The 320,000-SF (plus 180,000 band staging area) Pickle Line Tandem Cold Mill (PLTCM) incorporates two separate steel-making processes (pickling and cold milling) combined in a continuous line that spans nearly 1,600 feet. Barton Malow performed all civil, concrete, resteel, mechanical installation of all equipment, as well as boilermaker work. Accelerated 10 weeks during construction, AK Steel was able to increase the production of cold rolled sheets from 1.65 to 2.1 million tons per year.
Building Information Modeling (BIM) was a key factor in the PLTCM project. Originally used in the pre-construction process, BIM was utilized to verify quantities and in logistics planning for all trades to ensure our schedule was accurate. Once awarded the project, all subcontractors utilized BIM to coordinate the entire job, as well as to develop their shop drawings and fabricate from the model. In addition to utilizing BIM for coordination, in order to track all of the equipment, Barton Malow used Vela Systems to provide an electronic turnover package to AK Steel that includes a database of all equipment and its history throughout the project. AK Steel realized a $900,000 savings in quantity verification as bid process and a $10 million savings in interference resolution.
