and depends on the actions and judgement of each Corps District. Districts and their sponsors

need the dredging work accomplished and greatly prefer some sort of penalty short of disrupting

a contractor's work. For example, the Mobile District uses the following clause in their hopper

dredge rental contracts.

If the system is not operational within 30 days of the Notice to Proceed, or if the

system becomes inoperable for a period of time greater than allowed in the

specification, the hourly rate of pay for the dredge for 100% time will be reduced

to 95% of the original bid price until the system is fully operational.

Proprietary Information and Security. In consultation with the SI PAT team, the detailed

dredge data are considered proprietary as well as the contractor submittals. In contrast,

summarized data derived from detailed dredge data (i.e., ENG Forms 27 and 4267 time

distributions) are not considered proprietary.

SUMMARY: The SI system implementation process for hopper and pipeline dredges integrates

into the dredging contracting process. This process defines the interactive relationship between

the Corps and the dredging contractor with regard to dredge monitoring and helps the Corps to

perform its quality assurance role. In addition, the detailed dredging data can allow for new

ways to interact with the contractor.
