Concrete controls the job, as they say, and there’s no better way to control the quality, safety and schedule of a project than to perform the concrete construction with your own highly skilled crews. Sundt’s ability to self-perform complex, large-scale concrete work with care and precision made these two projects – one public, one private – enormously successful for their owners and occupants.
The seven-story Pima County Downtown Service Center in Tucson, Arizona, sits on top of exceptionally sandy soil, which would have made it difficult (and costly) to construct a traditional foundation formed around drilled caissons. Instead, the team opted for a compensating mat slab foundation situated 25 feet below grade to support the weight of the building. Spanning just over an acre, the five-foot-thick slab required more than 7,500 cubic yards of concrete – necessitating two of the largest concrete placements in Tucson’s history. All together it took a crew of 22 Sundt concrete laborers and foremen to finish the 300-plus truckloads of concrete that were placed in each pour.
Creating the new North American headquarters for Sony Electronics in San Diego, California, also began with a major concrete pour performed by our own crews. They placed and finished more than 4,100 cubic yards of concrete in just 14 hours to create a three-foot-thick slab that spans 39,000 square feet. The work was performed on a Saturday – beginning at 1:00 a.m. – to ensure adequate supply, since it used concrete from four different batch plants and required more than 400 delivery trucks.
