This project consists of remedial stabilization and elevation restoration of an existing concrete sidewalk and concrete wall/footing system that has experienced differential settlement due to subsurface erosion. The existing sidewalk is approximately twelve feet (12') wide. The northern edge of the sidewalk bears on an existing seawall and has remained generally stable. The southern edge of the sidewalk, located approximately twelve feet (12') south of the seawall, has subsided from its original constructed elevations by amounts ranging from approximately one-half inch ( 1/2 ") to a maximum of approximately sixteen and one-half inches (16.5") in localized areas. The original design and construction of the sidewalk and associated concrete wall were configured such that the southern edge (front) of the sidewalk was sloped to drain northward toward the seawall at an approximate slope of one percent (1%). Differential settlement has altered this intended slope and drainage pattern. The scope of work includesrestoring the sidewalk, concrete wall, and wall footing to the elevations and slopesshown on the Contract Drawings by means of installing remedial helical piles to the minimum depths indicated herein and on the Drawings. The installed piles shall serve as resistance elements for permanent jacking assemblies used to lift the wall footing, wall, and sidewalk back into their intended positions. Jacking assemblies shall be permanent components of the completed work and shall remain in place after lifting operations are complete. These assemblies shall be designed and constructed to withstand long-term exposure to the environmental conditions present at the site, including moisture and coastal conditions, and shall not be removed after installation. Due to settlement and cracking of the structure, subsurface voids have developed beneath the sidewalk slab and behind the concrete wall. These areas were originally backfilled with sand, which has since eroded as a result of washout occurring beneath the structure and wall footing. As part of the remedial work, core holes shall be drilled through the sidewalk slab at locations indicated on the Drawings or as directed in the field. Sand shall be pumped through the core holes to initially fill existing voids beneath the slab. Following initialsand placement, remaining voids beneath the sidewalk slab shall be filled by pumping flowable grout slurry to the underside of the slab. Flowable grout slurry shall also be pumped beneath the wall footing, as required, to stabilize and support the footing and wall after elevations have been restored. Upon completion of grouting operations, all core holes and surface disturbances in the sidewalk shall be properly filled, patched, and finished to match adjacent concrete surfaces.
