BERRY STREET PROJECT WINS ATC & SEI AWARD FOR
“BEST APPLICATION OF SEISMIC TECHNOLOGY OVER THE LAST DECADE”
DIS congratulates Simpson Gumpertz and Heger (SGH) for winning this prestigious award. The award was given at a Gala event hosted by the Applied Technology Council and the Structural Engineering Institute held
in San Francisco in December 2009.
WOODROW WILSON BRIDGE project was the Winner of ASCE’s 2008 Outstanding Civil Engineering Achievement Award (OCEA award). The $680 million project crosses the Potomac River at the southern tip of the District of Columbia. The 12-lane bridge contains America’s largest movable span comprising eight draw span leaves weighing 2,000 tons each.
UTAH STATE CAPITOL Seismic Base Isolation and restoration won the 2009 NCSEA Excellence in Structural Engineering Award. The 300,000 square-foot building was retrofitted with 265 base isolators. The project used innovative load transfer methods and huge pre-stressed beams to redistribute the dome column loads into the foundations.
DIS provided the isolators for a new mass damper incorporated into the seismic retrofit by the designer Miyamoto International. The tuned mass damper reduces the shaking of the building by modifying its response to the earthquake motion. The construction project will cost about $10 million and will be completed this year.
This hospital in Colombia was isolated to ensure that it will remain operational during and after an earthquake. The owner chose to isolate the hospital as an earthquake had severely damaged one of its non-isolated hospitals in the 2004 Magnitude 7.2 Cali earthquake. Base Isolation reduces the accelerations that the building will experience by a factor 4.
