Provide approximately 2-3 cores at the marked locations along with a core log indicating the <br /> depth of concrete and the depth of void(if present). <br /> 8. South Embankment Seepage Monitoring: It is suspected that seepage through the embankment <br /> behind the south abutment is due to the deteriorated condition of the upstream face of the dam and <br /> training walls. It is anticipated that the proposed repairs to the upstream face of the dam and training i <br /> walls may cause the seepage to stop. After the repairs are completed,Hanson will visit the site <br /> periodically to observe the south embankment for signs of seepage. Continued seepage may warrant i <br /> additional work in future repair contract to investigate and repair the source of the seepage. ', <br /> 9.
