Investigation Scope & Credentials
- Is the report stamped and signed by a licensed geotechnical engineer of record? *
- Does the scope of investigation match the project type, footprint, and load conditions? *
- Are the number, depth, and spacing of borings adequate for the structure and site area? *
- Is the report current and reflective of the final site grading plan? *
Subsurface Data
- Are boring logs, soil classifications, and laboratory test results included? *
- Is the groundwater elevation reported with seasonal high-water considerations? *
- Are expansive, collapsible, or organic soils identified and characterized? *
- Is a plasticity index / swell potential provided where expansive soils are present? *
Foundation & Bearing Recommendations
- Is the allowable soil bearing pressure clearly stated for the recommended foundation type? *
- Are settlement estimates (total and differential) provided and within tolerance? *
- Are deep foundation recommendations (piles/piers) provided where shallow bearing is inadequate? *
- Are lateral earth pressures and passive resistance values given for retaining/below-grade walls? *
Seismic & Site Hazards
- Is the seismic site class determined from measured or estimated shear-wave/soil data? *
- Has liquefaction potential been evaluated where applicable? *
- Are slope stability and global stability addressed for hillside or fill conditions? *
Earthwork & Construction Requirements
- Are site preparation, overexcavation, and engineered fill compaction criteria specified? *
- Is subgrade/pavement and slab-on-grade support addressed? *
- Are drainage, moisture protection, and grading recommendations included? *
- Is special inspection of earthwork and fill placement called for? *
- Photo of representative boring or test pit location
