50 • March 2018 www.concreteproducts.com COVER STORY READY MIXED Over the second weekend of 2018, lead contractor Barton Malow Co. of Southfield, Mich., mustered 131 tradesmen at the Arling- ton, Texas, Hilton Garden Inn for a continuous, 6,470-yd. pour, yielding what the project team and owner dubbed the Texas Mega Slab: A 256,000-sq.-ft. expanse of 8-in. thick, steel fiber-rein- forced concrete, placed and finished in under 1.5 days, at the GM Arlington Assembly Plant. Led by Laborer Superintendents Ethan Uhl and Brian Willard, with Project Director Chris Hofe, Senior Project Manager Josiah Goins and Construction Manager Craig Lowell supporting, the Mega Slab proved a successful exercise in planning and mass-con- crete placement. During preliminaries at the hotel, project leaders impressed upon tradesmen the a) idea of toughness, as in "Don't get complacent; stick with the plan"; b) importance of safety on a big project; and, need for quality control. By going over poten- tial hazards and dutifully crossing off each bullet point in the pre-task list, leaders and tradesmen set the stage for something special. Shift teams were defined in color-coordinated patterns, in addition to being staggered to ensure each member was well- rested for what would be a difficult project. The Mega Slab entailed nearly 33 consecutive hours of placing, raking, leveling, troweling and sawing. Barton Malow partnered with Virginia's Lloyd Concrete Services and Ohio's Unlimited Concrete Solutions to assemble the large array of specialty labor required. Assembly Required The Mega Slab supports additional capacity at the GM Arlington Assembly Plant, home to Chevy Tahoe production. Beginning in 2015, the automaker committed $1.4 billion for a three-year expansion of the operation, located between Dallas and Fort Worth. PHOTOS: Jon Humphrey, courtesy of Barton Malow
