On the Scene: Texas & Louisiana Industry Events for February 2018
At the General Motors Assembly Plant in Arlington, Texas, Barton Malow and its partners completed a mega-concrete-slab placement during the weekend of Jan. 13. Labor partner Lloyd Concrete Services Inc., Rustburg, Va., helped with the placement, while Unlimited Concrete Solutions, Columbus, Ohio, provided additional supervision and equipment.
The mega-slab spans 256,100 sq ft and features 8-in. steel fiber reinforced at 23 lb per cu yd, then hard-troweled as a continuous slab placement. The work took 32.5 hours, with an average of 315 cu yd of concrete placed per hour. Civil crews achieved an average grade within 3/16th of an in. across the placement. That level of accuracy kept the concrete purchase within 2% of the target.
