Page 36 of 59 September 2015 • 35 FEATURE COVER STORY NYS Thruway inspector remained on site to oversee testing. "The concrete reach[ed] 6,500 psi in as little as 24 hours, eventually hard- ening to 10,000 psi," says CPS Senior Project Manager John Pridgen. INFRASTRUCTURE IMPROVEMENTS The pier caps have been staged about a dozen at a time near the water by a 400-ton rail crane purchased in never-used condition from NASA. "We widened it 10 feet and converted it from electric to hydraulic power, and added remote ground control," Ogorchock says. Nine hundred feet of steel track was laid so the crane could transport the caps from production to a new 78- x 250-ft. load out slip. CPS's barge, "Gayle Force," rated at 3,700 tons for ocean travel and pur- chased several years ago for another job, has transported all precast units to the TZC project. Fully loaded with eight pier caps, the barge takes 2-½ days to reach the Hudson River construction site. CPS has 195 employees at the Chesapeake location, of whom 30 have been tasked with TZC contract work. Across the fabrication window, Pridgen calculates that crews placed nearly 11,000 yd. of concrete for the tower pier soffits, anchor pier soffits and pier caps. Pennsylvania-based Ken Stadden specializes in business-to-business marketing communications, and prepared the New NY Bridge report on assignment from BHS-Sonthofen Inc. RIGHT COAST ARRIVAL The I Lift NY Super Crane was purchased used and brought east from California, but remains registered with the Coast Guard as the Left Coast Lifter. TZC joint venture partners American Bridge and Fluor Enterprises had it built in 2008 to work on San Francisco Bay Bridge re-decking. Its heaviest pick to date has entailed a 600-ton precast concrete pile cap, to be followed by lifts of 900- to 1,100-ton mem- bers. I Lift NY will get more work when demolition of the original Tap- pan Zee Bridge commences in 2018. The equipment has a 1,699-ton lift capacity and 328-ft. main boom. A second crane, The Hank Hummel (see Concrete Products, August, page 32), named after an early Traylor Bros. vice president, plays second banana to the super crane, but is being used more consistently during construction. At 750-ton capac- ity, the Manitowoc 4600 is mounted with a ringer attachment welded to a 225- x 70-ft. crane barge, making it more versatile than I Lift NY, which doesn't swivel.
