Page 46 of 73 August 2019 • 45 COVER STORY ERNST COLLEGE PARK The College Park plant is tied into a central dispatch center at Lawrenceville headquarters. One-time driver Shameko McCants is among charter College Park plant team members and covers order scheduling and verification. Ernst Concrete tracks mixers across nine plants with the GPS-enabled Digital Fleet program. A Command Alkon CB200 panel controls the twin alley plant and provides manual back up. Vince Hagan engineers detailed College Park stairways, platforms and catwalks for navigating and maintenance ease, and con- fined caged ladders to a single silo. The wet alley's TM12 tilt mixer can deliver up to 12 yd. in a single batch. A unique hold- ing hopper design with integral aggregate, cement and water compartments allows a full 12 yards of material to charge tran- sit mix trucks at the same time the TM12 is loading a truck. The Command Alkon batching system will weigh up the next load for either the wet or the dry side of the plant, whichever is available in the job stack. This allows for increased production by having three complete batches in the cue, and enables operators to maintain high output with a range of mix designs. "This is one of the biggest plants in Georgia," says Plant Manager Admir Mijkic, who joined Ernst after operating concrete pumps and worked in central dispatch prior to being elevated to plant manager. "We are primarily running the dry alley, but can move into high production with central mixed. We have complete production back up for small to large orders."
