There is no proposal extension associated with Amendment 0001.** This is the solicitation notice. The Army Corps of Engineers, Philadelphia District, is issuing a Request for Proposal (RFP) for one (1) Firm Fixed Price Construction Contract. 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. Some of the embankments will include geogrid reinforcement. 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 management, aeration, promoting positive drainage, limiting construction traffic and allowing for drying days must be utilized to facilitate fill placement and compaction activities. It should be anticipated that protection of exposed excavation subgrades will need to be exercised to minimize disturbance. The contract documents will include available data from the latest subsurface investigations and associated geotechnical laboratory testing. A licensed Geotechnical Engineer will be required for the evaluation of this data and assistance in preparation of proposal documents as well as with work plans that will be required of the successful offeror. The work will also require the installation of three steel sluice structures and associated 30-inch steel outfall pipes for site drainage. The contract duration for construction is 550 calendar days from notice to proceed. In accordance with FAR 36.204 and DFARS 236.204, the Magnitude of Construction for this project is between $10,000,000 to $25,000,000. The NAICS Code for this project is 237990. This solicitation is being issued as a total small business set aside procurement. The Government intends to award a firm fixed price contract to the responsible offeror whose proposal conforms to the terms of the RFP notice, is determined fair and reasonable, and offers the best overall value to the Government as determined through the Best Value Trade-off process (FAR 15.101-1).
