PL84-99 Levee System 0561 (North) Levee Improvement Construction Project

PL84-99 Levee System 0561 (North) Levee Improvement Construction Project The Government anticipates issuing a Request for Proposals (RFP) with the intent of awarding a Firm-Fixed Price construction contract for the PL84-99 Levee System 0561 (North) Levee Improvement Construction Project. Project Description: This project consists of berm installation and levee slope repair. Berm Installation Seepage through or under the levee can be addressed by installing a berm on the landside of the levee. Berms typically lap partially up the slope of the levee and extend out into the adjacent area. Installing a berm consists of stripping a portion of the existing soil surface, and subsequently importing and placing rock materials. An underlying geotextile may also be installed. The bulk of the berm typically consists of drain rock. Larger (3- to 6-inch) rock may be installed along the berm perimeter for stability. When repairs are complete portions of the site may be reseeded and any damage to haul routes will be repaired. Berm installation is completed from the land. In some cases, temporary berms underlain by geotextile fabric are already in place. In these cases, the temporary material will be removed and stockpiled, the existing geotextile fabric will be removed and properly disposed of, and the stockpiled material will be reused to construct the permanent berm. Seepage berm installation are projected to be necessary at two locations. These berms are anticipated to range from approximately 400 to 800 feet in length, 20 to 30 feet in width, and involve rock volumes ranging from 1200 to 1700 cubic yards. Levee Slope Repair Repairing levee slope failures typically requires degrading a portion of the levee to remove slumped material and expose an appropriate repair surface, proper disposal of excavated material, importing replacement soil with appropriate geotechnical properties, and properly placing/compacting the new soil to restore the levee to its prior configuration. It may be necessary to obtain and place geotextile and rock at the base of the excavation before placing the new soil. Repair of slope failures on the waterside of the levee may require installing a coffer dam. In some cases, the repair may be constructed with rock rather than soil. When repairs are complete soil areas will be reseeded, any damage to haul routes will be repaired, and the surface material of the levee crown will be reestablished, if needed. Levee slope repairs are typically done from land. Levee slope repairs are projected to be necessary at one location involving three sub-sites along approximately 1200 feet of levee with an estimated volume of imported soil of 10,000 cubic yards. The volume of imported soil may be reduced by blending existing soil with a lesser amount of imported material in a manner where the blended material meets the applicable geotechnical standards. In accordance with the FAR 36.204, the magnitude disclosure of this construction project is between $1m and $5m. This proposed contract action will be conducted using FSC Code: Y1LC, Construction of Tunnels and Subsurface Structures and North American Industry Classification System Code (NAICS): 237990 Other Heavy and Civil Engineering Construction and the small business size standard is $36.5 million. The RFP is estimated to be issued on or about 15 March 2018 with proposals due tentatively on 17 April 2018. The RFP will be issued on the Government Point of Entry known as FedBizOpps (www.fbo.gov) and will establish a firm proposal due date/time. The site visit date, time and location will be identified in the solicitation.
