Life-cycle cost analysis doesn't work for bridges

Article Abstract:

The 1991 Intermodal Surface Transportation Efficiency Act requires the use of life-cycle costs instead of initial costs in evaluating public works and construction projects. However, this method may not work with bridges due to factors such as incomplete coherent cost data, the effect of technological developments on the materials, bridge design and construction techniques and variations in frequency of use and maintenance procedures. It may be possible to come up with a life-cycle cost model but projecting future costs will be largely hypothetical based on the data on hand.

Closing the loop

Article Abstract:

The $141 million Cooper River bridge has been built to withstand hurricanes, earthquakes and ship collisions, and is the longest bridge in South Carolina. Planning and designing the project took 10 years, and it was built in two separate construction contracts to encourage the participation of local contractors. The most significant feature of the Cooper River bridge is the main channel span, a three-span continuous parallel chord truss with a main span of 800 ft and side spans of 400 ft each. The Cooper River bridge withstood Hurricane Hugo even while under construction.
