Estimate:

Estimated Length of Project:
11/28/22 (Substantial Completion) + 30 (Final Completion)
The BASE BID Work shall include demolition of the existing Upper Guide Walls at both Kentucky River Locks 2 and 3 and the construction of new Upper Guide Walls consisting of sheet pile walls with tie-back anchors. These sheet pile retaining walls will be constructed along the same baseline as the current guide walls upstream from the lock chambers as shown on the Drawings. The BASE BID Work will also consist of site preparation, erosion and sedimentation control with fluctuating river levels, construction access, selective demolition, dredging, earthwork, constructing tie-ins to existing lock features, slope construction and protection, temporary shoring, drainage
improvements, and site grading and restoration work.
Demolition work at Lock 2 shall include the Upper Guide Wall and Upper Guide Wall Extension. The replacement Upper Guide Wall at Lock 2 will feature a tie-back anchor system to stabilize the new Upper Guide Wall and the adjacent slope up to state route KY-389. This anchor system will include an earth-retaining sheet pile wall at the
base of the slope with tie-backs anchored into the bedrock. The construction will also include a concrete sidewalk with mooring pins along the edge of the newly constructed guide wall, earthwork and slope regrading, and stone slope protection.
Demolition work at Lock 3 shall include the Upper Guide Wall. The replacement Upper Guide Wall at Lock 3 will feature a tie-back anchor system to stabilize the new Upper Guide Wall. This anchor system will include an earthretaining sheet pile wall at the base of the slope with tie-backs anchored into a sheet pile anchor wall. The construction will also include a concrete sidewalk with mooring pins along the edge of the newly constructed guide wall, earthwork and slope regrading, and drainage improvements.
