Fort Lauderdale, Florida, United States
To accommodate growth and expansion at the Ft. Lauderdale/Holly wood
International Airport in Florida, the interchange providing access from U.S. 1
and I-595 was reconstructed at a cost of $85 million. Beiswenger, Hoch and
Associates value-engineered the project to optimize the interchange design,
accelerate design speed, reduce right-of-way required, eliminate one railroad
crossing, and reduce structure and embankment costs.
The design reduced the structure by 30 percent, from three to two levels
with improved horizontal and vertical geometry. Beiswenger, Hoch used
GEOPAK for interchange geometry, Bentley Rebar for segment simulations, and
MicroStation for construction plan production. This saved valuable and critical
time in design, and the contractor benefited from the construction schedule
compression, completing the entire project six months ahead of schedule.
Villargordo Cabriel, Spain
The $200 million Contreras Bridge is a high-speed railway bridge over Contreras
Reservoir in Villargordo Cabriel, Spain. The 587-meter viaduct is divided into 12
intermediate spans of 43.5 meters and two end spans of 32.6 meters. The deck
is supported by a 261-meter curved arch, making this the longest arch bridge in
Spain and the longest railway concrete arch bridge in Europe. The Madrid-Valencia link will shorten journey time from 4 to 1: 30 hours.
The arch was built by cantilever construction supported on temporary stays.
EIPSA used RM Bridge to determine the correct forces of the stays and minimize
the number of stressing operations. Not a single correction of the stressing
forces was needed on site. RM Bridge also provided thorough checking of the
arch during construction.
