On Friday, May 9, 2014 at 10 PM in the Lower Shoal Creek area, the Construction Manager, Hensel Phelps, began pouring over 10,400 cubic yards of concrete over a 24-hour period to form the foundation of the New Central Library. The mat slab is approximately 200 ’x 200’ and is 5’-6” thick and has 1,433 tons of reinforcing steel. The placement of the mat slab is a significant milestone in construction, and heralds the beginning of vertical construction. The placement of the mat slab involved the non-stop delivery of concrete by more than 1,000 trucks. The planning to get to this point has been an exceptional example of the teamwork that continues to be the hallmark of the New Central Library project.
