Continuing Geotechnical Engineering and Construction Services

Consultant shall have the ability to interpret soil survey maps; interpret and evaluate general subsurface conditions; perform Standard Penetration Test (SPT) borings; measure groundwater levels; install well screen piezometers; perform field permeability tests and infiltration rate analysis; recover thin-walled tube samples; perform muck probing; and conduct laboratory tests to aid in classification of soils and measure strength of materials. Laboratory testing services may be from a subconsultant that is a certified laboratory. Consultant may be required to provide engineering analyses of soils to include allowable soil bearing pressures; estimated settlement; allowable pile capacity (tension and compression); lateral earth pressure coefficients for flexible and rigid retaining walls; slope stability analyses; seepage analyses; filter requirements and gradation; recommendations for site preparation and earthwork; estimates of the seasonal high water table; and review of construction plans and specifications. The findings of the field explorations, laboratory test results, and applicable engineering analyses shall be presented in an engineering report for review and acceptance by the District.
