Right of Entry: Prior to commencement of field work, COUNTY will provide Jacobs permission from the appropriate authorities to enter and survey the subject properties. Survey Accuracy: Vertical Control work will be Third Order, as outlined in the Federal Geographic Data Committee( FGDC) Geospatial Positioning Accuracy Standards, Part 4: Standards for Architecture, Engineering, Construction (A/E/C) and Facility Management. Horizontal Control: Will be performed using either standard surveying techniques or Global Positioning Satellite (GPS) system techniques meeting the specification requirements outlined in this scope. If standard surveying techniques are used, all horizontal control work will comply with Third Order Class I, as outlined in the FGDC Geospatial Positioning Accuracy Standards, Part 4: Standards for Architecture, Engineering, Construction (A/E/C) and Facility Management. If GPS is used, the relative horizontal accuracy shall conform to the FGDC Geospatial Positioning Accuracy Standards, Part 2: National Standard for Spatial Data Accuracy. • Survey and mapping will be certified by a surveyor currently licensed in the State of Washington and in good standing with the State licensing agency. • Deliverables provided by surveyor in PDF and appropriate electronic CAD file format. • Execution of fieldwork will not be delayed by travel and/or self -isolation restrictions locally and or nationally imposed due to COVID-19. Jacobs is not responsible for schedule changes related to COVID-19. Task 2.2 Geotechnical 1. Key geotechnical considerations will include pavement design and utility/earthwork recommendations. The geotechnical investigation scope may vary from that shown depending on concepts for roadway improvements and/or interaction with adjacent utilities and irrigation infrastructure. Additional geotechnical investigation and laboratory testing may be required if subsurface conditions are found to be more complex than assumed herein. 2. Desktop, Field, and Laboratory Investigation a. Review publicly available geologic maps, nearby well logs, and other available geologic/geotechnical information at or near the project site prior to field investigation. b. Participate in one (1) site visit to observe surface conditions, confirm drill rig access, staging and logistics, and mark exploration locations for public utility locate. c. Develop a safety plan for exploration work and coordinate with drilling subcontractor. d. Geotechnical Drilling and Sampling: Jacobs will subcontract with a geotechnical drilling company to obtain representative subsurface data for project design. A Jacobs geotechnical engineer or engineering geologist will direct, observe, and document ten (10) soil borings up to 15 feet deep each, or to bedrock, using hollow stem auger. Standard penetration testing soil samples will be collected in accordance with ASTM D1586 about every 5 feet of depth, or at the discretion of the on-site engineer or geologist. Rock coring is not planned, as it is assumed that the roadway and utility construction/improvements will not require confirmation of bedrock properties. Groundwater levels are assumed to correspond with water levels obtained during preliminary geotechnical investigation/monitoring previously performed. Borings will be abandoned in accordance with WA State Dept of Ecology requirements and the surface will be repaired or patched. Paved surfaces will be patched with asphalt cold - patch. Soil cuttings from the proposed borings will be spread on site. COUNTYwill provide a potable water source for using during drilling.
