INNOVATION IN BRIDGES
The master plan for the Velika Plaza beach community near the town of Ulcinj,
Montenegro, envisioned gradual reconstruction to enable environmentally
friendly economic development. As part of that plan, the EUR 16 million Port
Milena Bascule Bridge alleviated traffic congestion on the existing two-lane
regional road and provided an entrance to the future Port Milena marina for
yachts with tall masts.
DB Inzenjering devised a visually distinctive design with harp-shaped central
piers. The bascule bridge occupied less space above the river, and independent
structures on the left and right halves of the bridge allowed for easier
maintenance. RM Bridge was used for structural design and analysis of both the
concrete and steel structures. The precise and dependable results saved time
and enabled DB Inzenjering to create the optimal structure.
Hawk Technologies, a division of Talon Research, Inc., Hancock, Michigan,
developed an alternative to antiquated bridge inspections that pose unnecessary
risks to inspectors and costly delays to motorists. BridgeGuard is an innovative
infrared service for identifying and locating defects in bridge decks and
substructures. The device uses a vehicle-mounted thermal imaging sensor to
scan for delaminations, spalls, and cracks at speeds of up to 50 miles per hour.
During post-processing of image data, defects are tagged and located using
geographical coordinate and attribute information. This data file is formatted
for import to MicroStation. Power GEOPAK converts the BridgeGuard data
output into a CAD file format, which saves about 12 hours per bridge drawing.
BridgeGuard could avoid more than a million hours of traffic congestion and
millions of dollars in delays if deployed nationwide.
