The Cost of Environmental Protection In Construction Dredging

Leeser, T. T.

The cost of safeguarding the environment during construction dredging may have risen after the passage, beginning in the 1950s, of legislation to protect the environment. This might occur if increasingly stringent legislation were passed over the years or if the interpretation of existing legislation became stricter. One way to examine the impact is to study components of and trends in the cost of environmental protection. To keep this examination manageable the study was limited to construction dredging contracts in the continental United States planned, designed and contracted by Jacksonville District, U.S. Army Corps of Engineers. Line item pricing data collected from solicitation bid summaries were analyzed. The cost of environmental protection is a life-cycle cost, not simply a construction cost. To protect the environment, time and money are being invested in construction, and also in mitigation, planning, design, and post-construction monitoring.
