Dike Raising Killcohook Disposal Area

Read the official notice on SAM.gov

Summary from the notice

Contract work consists of a large-scale earthwork project to construct approximately 15,000 linear feet of earthen embankments at Cell 1 of the Killcohook Dredged Material Placement Facility (DMPF) adjacent to the Delaware River in Salem County, NJ. Approximately 500,000 cubic yards of dredged materials must be moved from within the approximately 300-acre site, compacted in lifts and final graded to meet the lines and grades required. Significant experience and expertise with large scale earthwork projects and access to a significant amount of earthmoving equipment and labor will be required to complete all work within an 18-month period of performance. The soils that comprise the available dredged materials are predominately fine-grained in nature (i.e., contain silts and clays of low and high plasticity), with some sand and gravel in limited areas. As such, these soils are highly susceptible to changes in moisture content which may limit construction activities during periods of wet or freezing weather. Contractor must be able to deal with problems that include seepage of water into excavations, softening of exposed subgrade soils, loss of soil shear strength, etc. It is anticipated that the existing dredged material proposed to construct the dikes will require consistent and active moisture conditioning to achieve a moisture content near or at optimum to achieve the specified compaction requirements. Consequently, prudent earthwork techniques such as disking, stockpile man…
