Site work for a water / sewer project in Lexington, Michigan. Completed plans call for site work for a water / sewer project.

Lexington Harbor Breakwater Repair includes repair operations on the north breakwater, a permeable rubble mound structure that currently allows sand to infiltrate and shoal within the harbor. Voids within the breakwater are contributing to sediment movement, and although the existing 5-foot-wide concrete walkway atop the structure is generally in good condition, the underlying sand-filled voids vary in depth and typically extend to the water level. The project objective is to convert the permeable structure into an impermeable one by constructing a grout curtain wall within the breakwater. Chemical grout will be installed within the sand-filled portions of the structure, while cementitious grout will be used above those areas. This grout curtain wall is intended to prevent further sand migration through the breakwater. Upon completion of grouting operations, the Portland cement concrete walkway will be reconstructed. The Bidder Inquiry System will stop receiving new inquiries ten (10) business days before the bid due date in order to ensure adequate time is allotted to form an appropriate response and amend the solicitation if necessary. *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document. PN - 506358, W911XK, 751/17267.BDW This project includes breakwater repair operations at Lexington Harbor. The north breakwater is a permeable rubble mound structure and allows sand shoaling within the harbor. Voids in the north breakwater are exacerbating sediment infiltration within the harbor. A walkway is present atop the north breakwater. The walkway is approximately 5 feet wide and generally in good condition. The north breakwater voids are partially sand filled. The sand fill depth varies; however, sand generally extends to the existing water elevation. The project objective is to alter the existing permeable rubble mound breakwater structure to an impermeable structure. The proposed scope of work includes constructing a grout curtain wall within the structure. The proposed grout curtain wall is chemical grout and a cementitious grout material. The chemical grout material is proposed within the sand filled breakwater structure. The cementitious grout material is proposed above the sand filled area. The intent of the grout curtain wall is to prevent sand from infiltrating through the breakwater structure. The existing Portland cement concrete walkway is reconstructed upon completion of grouting operations. As previously stated, the project includes breakwater repair by constructing a grout curtain wall and Portland cement concrete walkway reconstruction.
