Design - Chicago Erosion Environmental Construction

The project will include, but not be limited to, the following: 1. Contractor shall review any available information for the area of the work to determine any impacts on the scope of work including any previous repair work or projects completed including all reports, drawings, field reports, and photographs to use as the basis for the new work avvvvvvvand gain familiarity with the site. 2. Contractor shall survey the existing conditions of the buff area for familiarization to determine the deficiencies found and verify the appropriate approach for repair and replacement of the affected areas. 3. Contractor shall prepare and submit a QA/QC Plan defining the quality requirements, procedures and processes to be implemented for the project. 4. Contractor shall prepare and submit a Safety Plan defining all of the safety requirements, procedures and processes to be implemented for the project. 5. Contractor shall prepare and submit a project schedule showing progress of all major portions of the work and project milestones. 6. Contractor shall follow all environmental requirements for the project. 7. Contractor shall prepare a phasing work plan for sequencing of the work to minimize the impact of the work on training activities for that will continue to use areas of the site during construction. The Government is looking at two phases of the work. The first is the top of bluff stabilization and stormwater control measures and the second phase is the 8. Contractor will provide temporary safety barriers and signage for protection of people and the work during construction. 9. Contractor shall be responsible for providing the following work tasks for the erosion control work based on the construction documents developed for the project. a. Installation of a storm sewer running parallel to the top of the bluff conventionally by open cutting a trench with drainage inlets placed at regular intervals. b. Grading improvements including a shallow swale to capture the runoff flowing toward the bluff and to convey the runoff into the sewer inlets. c. Connecting any existing storm sewer lines to the new sewer system running perpendicular to the bluff installed by directional drilling methods to eliminate point source discharges onto the side of the bluff. d. Installing an anchored sheet pile retaining wall at the top of the slope with the sheet pile wall driven down 25 to 30 feet from the top of the slope. e. Placing a cap on the top of the sheet pile retaining wall and anchoring a new FBI approved security fence at the top of the wall. f. Providing slope improvements to include brush removal, selective tree removal, and tree trimming to open the bluff ground to sunlight. g. The bluff should then be revegetated with deep rooted grasses to hold the surface topsoil in place and resist erosion. h. Place and install armor stone, similar to the stone used along the lakefront south of the FBI Training Facility in Foss Park, at the toe of the slope to reduce the regression of the crest of the slope and protect the toe of the slope from wave action. The result of this market research will contribute to determining the method of procurement.
