What is a Geotechnical Report?The geotechnical report is the tool used to communicate the site conditions and designand construction recommendations to the building design, roadway design, bridge design, andconstruction personnel. Site investigations for a building project would involve the site classification, recommendation on footing type and foundation design parameters, excavation conditions, groundwater hydrogeology, geotechnical parameters for design of retaining wall system; while transportation projects have the objectiveof providing specific information on subsurface soil, rock, and water conditions.

Interpretation of the site investigation information, by a geotechnical engineer, results indesign and construction recommendations that should be presented in a projectgeotechnical report. The importance of preparing an adequate geotechnical report cannotbe overstressed. The information contained in this report is referred to often during thedesign period, construction period, and frequently after completion of the project(resolving claims). Therefore, the report should be as clear, concise, and accurate. Bothan adequate site investigation and a comprehensive geotechnical report are necessary toconstruct a safe, cost-effective project.

Geotechncial Engineers need these reports to conduct anadequate review of geotechnical related features, e.g., earthwork and foundations.The State or their consultant should prepare “Preliminary” geotechnical reports forsubmittal to the design team whenever this information will benefit the design process.Early submittal of geotechnical information and recommendations or engineeringevaluation of preliminary data may be necessary to establish basic design concepts ordesign criteria. This is commonly the case on large projects or projects containingcomplex or difficult geotechnical problems where alignment and/or grade changes maybe appropriate based on geotechnical recommendations.

The development of a “Final”geotechnical report will not normally be completed until design has progressed to thepoint where specific recommendations can be made for all of the geotechnical aspects ofthe work. Final alignment, grade, and geometry will usually have been selected prior toissuance of the final geotechnical report.While the geotechnical report content and format will vary by project size and highwayagency, all geotechnical reports should contain certain basic essential information,including:

• Review of existing geotechnical report and geotechncial data in public domain or surrounding areas;
• Summary of all subsurface exploration data, including subsurface soil profile,exploration logs, laboratory or in situ test results, and groundwater information;
• Interpretation and analysis of the subsurface data;
• Site classification or site reactive classification;
• Specific engineering recommendations for design of foundations and retaining walls;
• Discussion of conditions for solution of anticipated geotechncial problems; and
• Recommended geotechnical special provisions.
