Pennsylvania Turnpike Commission Accelerated Bridge Construction Program
STV was contracted by the Pennsylvania Turnpike Commission (PTC) to perform construction management and inspection services for the agency’s first foray into accelerated bridge construction (ABC) along the 360-mile-long turnpike.
STV’s contract is for overseeing the construction for five bridges, including twin 150-foot-long, two-span bridge superstructures over Brush Creek on I-76 in Beaver County, PA, the first such PTC replacement that used the ABC methodology. The twin replacement spans were constructed adjacent to the Turnpike and were “slid” into place during a 55-hour window.
All bridge replacements featured a significant public outreach component in advance of weekend closures. Other services provided by STV included constructability reviews, cost estimating, value engineering, bid reviews and packaging, and project scheduling.
