Crews celebrated the hoisting of the final two steel beams atop the D-backs and Rockies clubhouses at Salt River Fields at Talking Stick, just five and a half months after the first concrete pour for the new spring training home for the Arizona Diamondbacks and the Colorado Rockies.

Mortenson Construction is constructing the 140-acre project within the Salt River Pima-Maricopa Indian Community near Scottsdale. Designed by HKS Architects, the project contains an 11,000-seat ballpark, 12 practice fields, as well as Major and Minor League clubhouses, training facilities and offices for each team. The facility will open in February 2011.

The topping out is concurrent with the final pouring of 30,000 cubic yards of structural concrete, self-performed by Mortenson Concrete. “The project is on track as timely information exchange and decision making has been facilitated by the co-location of the Community, HKS and Mortenson in the jobsite office,” says Eric Grenz, project manager, Mortenson Construction.
