In December 2008, Haynes Whaley Associates participated in the concrete mat foundation pours for the new Administrative Support Building for The University of Texas M. D. Anderson Cancer Center in Houston, Texas.   Vaughn Construction, together with Baker Concrete Construction, completed the first 4,000 cubic yard mat pour on December 12th at a rate of 570 cubic yards per hour.  The second, larger mat pour was completed on December 19th in about 22 hours.  It totaled 17,500 cubic yards.  Seven concrete pumpers were used, supplied by about 100 concrete trucks.  1,960 tons of steel reinforcement were used in this pour.  Over 2,400 man-hours were expended.

The ASB mat pour is the second largest building mat foundation constructed in the United States of America.  It is second only to the Venetian Hotel in Las Vegas, Nevada.

The scale of this construction required participation from all involved, including the architect, WHR; the geotechnical engineer, Ulrich Engineers; the testing lab, Earth Engineering; and the concrete consultant, Carrasquillo Associates, LTD.
