With the second largest installed capacity, the United States is ranked first in the world in annual wind power production; the U.S. Department of Energy forecasts wind power supplying 35 percent of the nation’s energy by 2050. However, at this time, the United States' East and West coasts lag behind the Midwest in wind energy production, with many Southeast states currently having no wind energy potential.

Pleasant Valley Pedestrian Bridge Wins Project of the Year Award

Award-winning steel pedestrian bridge.

The Pleasant Valley Pedestrian Bridge connects Washington State University’s Vancouver campus with Pleasant Valley Community Park. BergerABAM was hired by Fabrication Products to perform engineering calculations on the 180-foot-long weathering steel pedestrian bridge.

BergerABAM was the engineer-of-record for the bridge itself and although the team was not responsible for the abutment or pier design, they nevertheless had to be very mindful and creative to detail the connections to allow for easy assembly in the field—within a 1/4-inch precision to fit on the abutments and piers. This 180-foot-long, 8-foot-wide, three-span warren truss bridge was shipped in three segments, assembled on site, lifted in one segment, and lowered into place.
