Oldmans Dredged Material Placement Facility (DMPF) Dike Raising Construction   3

PURPOSE: The U.S. Army Corps of Engineers, Philadelphia District, intends to award a firm fixed-price construction contract for the Oldmans Dredged Material Placement Facility (DMPF) Dike Raising Construction Project. DESCRIPTION: Contract work consists of a large-scale earthwork project to construct approximately 12,000 linear feet of earthen embankments at the Oldmans DMPF adjacent to the Delaware River in Salem County, NJ. Approximately 564,200 cubic yards of dredged materials must be moved from within the approximately 290-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 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 the proposal package as well as 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 sluice structures and pipes will be provided as Government Furnished Materials. The award will be made based on the best overall (i.e., best value) proposal that is determined to be the most beneficial to the Government, with appropriate consideration given the three (3) evaluation factors: Technical Approach, Past Performance, and Price. DISCLOSURE OF MAGNITUDE OF THE PROPOSED CONSTRUCTION PROJECT: $10,000,000 and $25,000,000. NAICS CODE AND SBA SIZE STANDARD: 237990, Other Heavy and Civil Engineering Construction, Size Standard $45.0M. PERIOD OF PERFORMANCE: 550 Calendar Days from the Notice to Proceed (NTP). SYSTEM FOR AWARD MANAGEMENT (SAM): Offerors are required to be registered in the System for Award Management (SAM) database (https://sam.gov) and PIEE at the time a proposal is submitted in order to comply with the annual representations and certifications requirements. Registration for PIEE is required as this is the only place proposals shall be submitted. Proposals must be submitted in PIEE Solicitation Module. ADDITIONAL INFOMRATION: Specific information pertaining to this procurement will be available in the solicitation. The solicitation documents will be posted on the SAM.gov website, https://sam.gov and PIEE Solicitation Module. It is and will continue to be the responsibility of all potential Offerors to monitor the SAM.gov website for any amendments, updates, responses to questions and answers, etc. as the Government will not be maintaining a mailing list.
