Example scopes are provided below. Scope of Services Geotechnical Design • Project coordination, including meeting with the representatives of the Agency and their de- sign team to discuss our scope of work. • Review of preliminary project plans, geologic and seismic hazard maps, and readily availa- ble geotechnical reports to evaluate possible geologic hazards that may impact the proposed construction. • Acquisition of permits necessary to proceed with our subsurface evaluation. • Geotechnical site reconnaissance to document the site conditions and to select and mark the proposed excavation locations for underground utility location. • Drilling, sampling, and logging of small -diameter and/or large -diameter exploratory borings and/or excavation of exploratory test pits. The depths of the excavations will depend on the details of the proposed project and site location. Traffic control will be performed, as appro- priate, in general accordance with the W.A.T.C.H. manual. • Laboratory testing of representative soil samples to evaluate the soil characteristics. La- boratory testing may include in-situ moisture and dry density, gradation, maximum density and optimum moisture content, consolidation and expansion potential, expansion index, consolidation, shear strength, corrosivity and sulfate content, and R -value testing. • Data compilation and geotechnical analysis of field and laboratory data. Our analyses will address the following: • Suitability of the site for the proposed construction from a geotechnical perspective. • Description of the site geology and on-site soils anticipated during construction, includ- ing an evaluation of geologic hazards that might be present at the site.
