www.concreteproducts.com April 2014 • 17 NEWS SCOPE READY MIXED Concrete contractor Conco Cos. staged 13 of its pumps—from a total of 19 machines on site—to place mixes for a 17.5- to 18-ft. thick mat as far as 100 feet below grade. The foundation mix is designed with a 25 percent fy ash binder and required to meet 6,000 psi compressive strength at 90 days. Headwaters Resources shipped Catalina Pacifc 1,800 tons of fy ash from its Pomona, Calif., terminal. In addition to aggregates from its Los An- geles County sites, CalPortland supplied the Catalina Pacifc and A&A; plants more than 5,000 tons of Type II cement from its Colton and Mojave, Calif., mills. The Wilshire Grand main pour and subse- quent concrete deliveries netted a mat up to 20-ft. thick, partly refecting the high seis- mic factor accompanying a southern California high-rise building. It tested CalPortland's raw material and ready mixed production and de- livery capabilities, the latter measured partly on truck scheduling and routing success. Cata- lina Pacifc's feet runs on the Android-based GeoTrax mobile feet management platform of TruckTrax, a Vancouver, Wash., technology pro- vider in which CalPortland is a partner. "GeoTrax played two important roles in the overall success of the Wilshire Grand founda- tion pour. We were controlling dispatch from the job site, and GeoTrax was able to give us an 'electronic bird's eye view' of what was hap- pening at the job site and remote plants," says Catalina Pacifc Dispatch Manager Bryan Power. "It provided ticketing data so we could proper- ly track the overall production at the multiple batch plants servicing the pour. "The use of the GeoTrax tablets by the driv- ers allowed us to track individual trucks as needed and provide location data for dispatch- ing and ticketing purposes. GeoTrax provides notifcation to Clearview /TruckTrax that a specifc truck has broken the 'Electronic Fence' at the ready mixed plant and is available to be dispatched. That information includes the truck identifcation number and eliminates the need for the dispatcher to manually enter the information when vehicles arrive." Catalina Pacifc will deploy the GeoTrax technology throughout the Wilshire Grand Center contract, which over a 2014-2016 schedule requires upwards of 100,000 yards for the steel framed tower's cast-in-place core and composite foor slabs. Designed by Los Ange- les' AC Martin Partners, the $1 billion, 1,100-ft. property will mark a new height record for a U.S. building west of the Mississippi. Developer Korean Air, which acquired the original facility in 1989, then operating as the Los Angeles Hil- ton & Tower, is targeting a 2017 Wilshire Grand Center opening. The University of Southern California marching band ushered the Catalina Pacifc feet to the pour. A USC alumnus, Catalina Pacifc Vice President and General Man- ager Melanie O'Regan observed the procession from the lead mixer. GUINNESS RECORD, NRMCA RECOGNITION PHOTOS: CalPortland (site); Concrete Products (NRMCA award) As the fnal yard set more than 2,100 loads later, she assembled with project offcials and Guinness World Records adjudicator Michael Empric (third from left), who confrmed the new concrete place- ment milestone. Joining them are (from left) Turn- er Construction's Scott Borland; Conco's Rick Park- er; Turner's Mike Machesano; Conco's Jesse Cook; and, Catalina Pacifc's Charles Kerzic. Two weeks after the Wilshire Grand Center mat foun- dation pour, O'Regan joined colleagues in Las Vegas at the annual convention of the National Ready Mixed Concrete Association, which presented a Special Rec- ognition Award honoring the job's success.
