Civil | BERGMANN ASSOCIATES – WALKWAY OVER THE HUDSON Bridging the Gap A fter the grand opening celebration of the Walkway Over the Hudson bridge project on Oct. 3, the 1.25mile modern walkway has been a site for a wedding, family gatherings and a route for avid walkers, runners and bikers. “The views are spectacular,” Bergmann Associates Principal Peter Melewski says. “People have fallen in love with it since it opened.” The Walkway Over the Hudson bridge, a $35 (without future elevator) million project in the city of Poughkeepsie and the town of Lloyd, N.Y., was a dormant railroad bridge originally constructed in 1888. It went through many uses over the years until finally a grassroots community organization – also called Walkway Over the Hudson – purchased the bridge in 1998 for $1 to convert it into a walkway for residents and visitors. Bergmann Associates performed the planning, structural inspection, design and construction inspection of the bridge. “The effort entailed conducting a full, hands-on inspection, detailed design, environmental processes and applying for a number of regulatory and stakeholder permits,” Melewski says. Other firms on the Bergmann team included the McLaren Engineering Group, Howard/SteinHudson and Skala Ropeworks. The last time the bridge was inspected was in the early 1980s. The preliminary inspection of the structural steel involved rope climbing and examining the steel section loss and deterioration of the steel. The average section loss for primary members was 10 to 15 percent, although some secondary bracing members had a section loss as great as of 50 percent. “The rate of corrosion since the early 1980s was slow, which was encouraging for its proposed use,” he says. “The project included $5.5 million in steel repairs. The steel superstructure is expected to serve generations to come.” WALKWAY OVER THE HUDSON IS A HISTORIC PROJECT FOR LOCAL COMMUNITIES. BY LIBBY JOHN »The Walkway Over the Hudson spans 1.25 miles over the Hudson River. “It cou a without ldn’tphbli happened the u vec/private teamwork.” –Peter Melewski, princip • Cost: $38 • Location: Poumillion • Scope: Bridge ghkeepsie, N.Y. renovation Bergman A o c Walkway nOverssthiates – e Hudson www.bergmannpc .com al Staying on Track The tight schedule was the biggest challenge the project faced, Melewski says. “We had a notice to proceed with the start of the structural inspection in August 2007, and we had to open in time for the state’s 400th anniversary celebration of Henry Hudson’s voyage , [which was Oct. 2 to 3, 2009],” he says. “We only had two years.” The fast-track schedule meant Bergmann had to complete aspects of the project simultaneously, such as field structural inspection, design, environmental review and permitting. The design was bid at the 90 percent complete stage, so that the means and methods of the selected contractor for installing the nearly 1,000 concrete panels could be incorporated into the final design, he explains. The general contractor – Harrison & By the Numbers The Walkway Over the Hudson bridge: • Is 1.25 miles long; • Is 25 feet wide; • 3,000 feet of the bridge is over the Hudson River; and • Has three river overlook decks that are 35 feet wide each.
