A. The Government will inspect final foundation surfaces and perform geological mapping of the existing impervious core and bedrock between the existing dam and dike.

1. The existing impervious zone or core is susceptible to cracking when drying out and should be protected from drying. Protect existing core in accordance with the protection requirements above.

2. The maximum exposure time for the bedrock upon reaching final grade is 14 days to preserve the natural moisture conditions of the rock mass to minimize deterioration during excavation.

E. Provide excavation equipment and operators to aid the COR in the evaluation of each foundation section as required.

F. Final inspection of the foundation will be performed at the completion of geologic mapping, final excavation and foundation treatment within the existing zoned embankments and on the abutment foundation surfaces. Final foundation surfaces may require recleaning as directed by the COR. Allow up to 1 day for foundation approval of the inspection area. Immediately following the foundation inspection period, the COR will either approve the foundation section for permanent construction or will direct the Contractor to perform additional excavation to remove unsuitable materials. If, during inspection following final excavation, the COR determines that additional excavation is required, any surface which requires recleaning for foundation treatment will be inspected by the COR. Equipment traffic on the final approved surface shall be minimal.

If equipment traffic damages an approved surface the COR will direct the Contractor to perform additional cleanup.

G. For final cleanup of the foundation rock surfaces for fill placement, clean all loose and weathered rock and surficial units with the use of vacuum and or air pressure as directed by the COR. Only the minimum amount of air pressure required to effectively clean the surfaces is allowed. Place fill onto the approved surface within a day of Government approval.

2. Prior to application of foundation treatment, the final foundation surface shall be cleaned for geologic mapping, inspected, and approved by the COR to perform specified foundation treatment.

3. The foundation treatment for soil foundations will likely consist of overexcavating soft and/or saturated materials and replacing with designated compacted zone material(s).

4. The foundation treatment for fractures in exposed bedrock within the spillway crest structure foundation and for fractures in exposed bedrock beneath the dam and dike includes cleaning out selected fractures and placing slush grout in accordance with Section 31 23 13 – Slush Grouting in selected open fractures and in any fractures that are cleaned out.

5. The COR will evaluate the need for additional excavation of zones of decomposed or broken rock.

6. Offsets in the final bedrock surface shall be shaped by removing additional bedrock as approved by COR.
