The scope of the proposed study is to prepare two alternatives <br />for mitigating the failure that would be acceptable to both <br />Cyprus and MLRD. The method of investigation and mitigation <br />design is outlined in the following sections of this proposal. <br />PROPOSED INVESTIGATION AND DESIGN <br />FIELD INVESTIGATION <br />We propose to visit the site and to document the site condi- <br />tions of the failure. This documention will use the topo- <br />graphic base obtained earlier by Cyprus. Further, detailed <br />surveying will be required during or immediately following <br />our site visit. During our visit, we will stake out import- <br />ant points that will later be surveyed by Cyprus. <br />Our field investigation will require <br />shallow test pits in the failure area <br />access road to the intermediate bench <br />prior to our visit. This access road <br />construction later in 1989. <br />MITIGATION DESIGN <br />excavation of several <br />with a backhoe. An <br />should be constructed <br />will be used for actual <br />After the field investigation and the site survey work by <br />Cyprus, alternate methods of failure mitigation will be iden- <br />tified and reviewed. They will include methods of failure <br />mitigation discussed earlier in this proposal and other <br />methods that may be identified during our study. They also <br />will include simplified stability analyses of the slope <br />after the failure and after stabilization. <br />We propose to prepare these alternatives in a draft from, <br />together with approximate cost estimates. The alternatives <br />would be presented to Cyprus and MLRD for their evaluation. <br />Following the selection and approval of a suitable alter- <br />native, design drawings and specifications for construction <br />of the selected alternative will be prepared. <br />MEETINGS WITH CYPRUS AND MLRD <br />Two meetings have been scheduled with Cyprus and MLRD during <br />the proposed study: one meeting with Cyprus after the alter- <br />natives for failure mitigation are prepared, and one meeting <br />with MLRD prior to the preparation of the final set of the <br />failure mitigation drawings, and technical specifications. <br />REQUIREMENTS OF CYPRUS <br />This proposal assumes that Cyprus will provide CH2M HILL <br />with all necessary surveys required for the failure <br />DEN/40Y/020 5 <br />
