Gray & Osborne will submit the following: <br />Electronic survey data in CM13D 2014 format for Topography and Right of Way survey work. <br />09 Electronic copies in .pdf format of survey field notes. <br />Excel spreadsheet of Survey Control for incorporation into engineering documents Identifying <br />horizontal and vertical coordinates and physical descriptions of site Benchmarks. <br />GEOTECHNICAL STUDY <br />PanGEO will perform the geotechnical study. <br />Existing Information Review — Review existing, readily available geologic and geotechnical information in <br />general vicinity of the project area. <br />Field Exploration & Lab Testing — Perform a visual site reconnaissance and mark locations for one test <br />boring at each of the four culvert replacement locations and arrange one -call utility locating. Subcontract <br />drill rig and crew and perform four test borings not to exceed 30 feet deep each. Monitor and log the test <br />borings by a PanGEO geotechnical engineer or engineering geologist. Obtain Standard Penetration Test <br />(SPT) samples at approximately 5 -foot intervals when drilling in soil. Perform index lab testing on select <br />samples collected from the test borings for sample description and material property identification. <br />Engineering & Regortin,g -- Based on the information obtained from the information review, field <br />explorations and lab testing, prepare geotechnical engineering recommendations for culvert replacement <br />foundation support including direct support on grade, driven piles and spread footing options, as <br />appropriate. Provide estimates of nominal strength and service bearing resistance for new or replacement <br />foundations in general accordance with AASHTO LRFD methodology. Provide culvert and headwall <br />backfill design parameters for lateral earth pressures. Provide construction considerations. Prepare draft <br />and final reports containing results and conclusions of the reconnaissance, field explorations, lab testing <br />and engineering analyses. <br />Assumptions and Exclusions: <br />Right -of -entry and/or permits to be provided by Kittitas County, if necessary. <br />Traffic control and flagging for drilling of test borings, if necessary, to be provided by 10Ettitas <br />County. <br />Drilling at all four locations will occur on a single mobilization of drill crew and equipment. <br />Approximate locations of exploration points will be referenced to known site features. Survey <br />location of the actual test boring locations will be by others, if necessary. <br />The site soils are assumed to be "clean" (i.e., no hazardous materials or contamination), therefore <br />drill cuttings will be disposed of on site. No archeological screening of cuttings or samples <br />produced or collected from the borings will be performed. <br />The assessment of potential presence or absence of wetlands on the site is excluded from this <br />scope of work. <br />The assessment of potential presence or absence of chemical or hazardous material properties of <br />soil and groundwater in the geotechnical borings is excluded from this scope of work. <br />HYDRAULIC STUDY <br />Watershed Science and Engineering (WSE) will provide hydraulic design support for each crossing. <br />Specific tasks to be completed by WSE for each crossing are described below. <br />Page 2 <br />
