Kittitas County Upper Road Maintenance Facility <br />Exhibit A - Scope of Work <br />January 8, 2017 <br />• Up to two (2) bid addenda will be issued. <br />• Representatives from the Consultant team are not required at the pre-bid site visit or bid opening. <br />• CAD files, if provided for convenience, are not considered to be construction documents and <br />successful bidder will sign a use agreement. <br />TASK 5 - SITE INVESTIGATIONS <br />Objective: Geotechnical engineering studies and report for Consultant preparation of construction <br />documents. Site investigations are conducted during Schematic Design Phase on schedule. <br />Consultant Disciplines <br />5.01 Geotechnical Engineering <br />Tasks Deliverables: Geotechnical Engineering. <br />• Review the proposed Road Maintenance Facility development plans as they become available. <br />• Review topographic and geologic maps of the project site and area. Review previously completed <br />geotechnical studies for nearby properties (PSE Substation). <br />• Develop a subsurface exploration plan and proposed exploration map for the project. <br />• Conduct a series of test pit explorations using an excavator provided by the County. <br />• Mark explorations in the field using wooden stakes about five to seven days prior to initiating the <br />subsurface exploration program. Contact the One Call utility notification center to locate publicly <br />owned subsurface utilities at the exploration locations. We will subcontract a private locate <br />company to clear the proposed boring sites with respect to privately owned utilities. <br />• Perform a geologic reconnaissance of the site when we mark exploration locations. We will note <br />vegetation patterns, areas of wet ground and/or standing water and evaluate any soil exposures <br />or nearby slopes. <br />• Limits testing, if appropriate. <br />• Describe site conditions including subsurface soil and groundwater conditions encountered in the <br />test pits, and laboratory test results. <br />• Develop recommendations for site preparation and earthwork based on the data and our <br />understanding of the proposed site development. The site has a gradual downward slope to the <br />northwest, so some earthwork will be required to achieve level site grades. <br />• Provide recommendations for temporary and permanent slopes. Recommendations for shallow <br />foundation support, including footing size, allowable soil bearing pressure and estimated post - <br />construction settlements. <br />• Discuss footing construction considerations including excavation, bearing surface preparation, <br />material requirements and compaction requirements. <br />• Perform geotechnical laboratory tests on representative samples obtained from the explorations. <br />• Provide subgrade preparation recommendations and criteria for modulus of subgrade reaction <br />for design of slabs -on -grade. <br />• Evaluate lateral earth pressures for design of below -grade structures. <br />• Provide recommendations for seismic design in accordance with 2016 International Building Code <br />(IBC) and local standards. This includes an assessment and discussion of liquefaction potential <br />and estimated ground settlement, and a discussion of potential remedial measures, as applicable. <br />Page 19 Maintenance Facility Design Phase 1 KPG <br />
