Seattle swings again

Article Abstract:

The 1992 Outstanding Civil Engineering Achievement Award was given to the West Seattle Low-level Swing Bridge, the only existing hydraulic-powered double-leaf concrete swing bridge. Its design and construction posed challenges to the engineers and contractors who had to consider load and seismic factors, traffic management, continuous telephone and water service during line relocation and protection of migrating fish. Designers found the usual design impractical and their creativity produced an efficient hydraulic swing bridge that is safe, earthquake-resistant, sturdy, and maintainable.

The great Texas prison caper

Article Abstract:

A $140-million emergency program was implemented in prisons in Texas to mitigate a surplus of 30,000 prisoners by building 32 new dormitories, three food service facilities and a boot camp. Engineers, architects and executives from prominent companies such as Butler Construction Co succeeded in accommodating 10,688 prisoners by constructing over 30 buildings with over 10,000 beds in minimum moderate security dormitories in the county.

Taming the Red River

Article Abstract:

The US Army Corps of Engineers completed the construction of the $1.8 billion Red River Waterway project. The project, which took 25 years to complete, involved the construction of five sets of locks and dams to keep the river in its new channel. It is expected to make Shreveport, LA, a viable destination for barge traffic, making it very attractive to investors.
