Burgess & Niple (B&N) was retained by Dong Ah Construction Company, a major South
Korean construction company, to provide peer review of a suspension bridge design
prepared by a Korean/Japanese design consultant team. The new suspension bridge,
with a total length of 2,960 feet, carries a new highway across Kwang An Bay in
Pusan, South Korea’s second largest city and a major port. A new law, initiated
in Korea following several major structure collapses, required that contractors
be responsible for designs, thus necessitating the need for peer review.
B&N, teaming with Steinman Consultants of New York City, performed a complete and
independent structural design check of all suspension bridge components including
main cables, suspenders, towers, deck, stiffening truss, anchorages, foundations,
and other components. The design review also included fatigue, seismic, and wind
tunnel test analyses and review. In addition to computational checks, B&N/Steinman
also provided a review of the bridge design plans and provided recommendations for
revisions and improvements to the design.
