1 <br /> 1 Appendix B <br /> Geotechnical Report Limitations and Guidelines for Use <br /> AET Project No.22-00012 <br /> B.1 REFERENCE <br /> This appendix provides information to help you manage your risks relating to subsurface problems which are caused by <br /> construction delays,cost overruns,claims,and disputes. This information was developed and provided by ASFE',of which, <br /> we are a member firm. <br /> B.2 RISK MANAGEMENT INFORMATION <br /> B.2.1 Geotechnical Services are Performed for Specific Purposes,Persons,and Projects <br /> Geotechnical engineers structure their services to meet the specific needs of their clients. A geotechnical engineering study <br /> conducted for a civil engineer may not fulfill the needs of a construction contractor or even another civil engineer. Because <br /> each geotechnical engineering study is unique,each geotechnical engineering report is unique,prepared solely for the client. <br /> No one except you should rely on your geotechnical engineering report without first conferring with the geotechnical <br /> engineer who prepared it. And no one, not even you, should apply the report for any purpose or project except the one <br /> originally contemplated. <br /> B.2.2 Read the Full Report <br /> Serious problems have occurred because those relying on a geotechnical engineering report did not read it all. Do not rely on <br /> an executive summary. Do not read selected elements only. <br /> B.2.3 A Geotechnical Engineering Report is Based on A Unique Set of Project-Specific Factors <br /> Geotechnical engineers consider a number of unique, project-specific factors when establishing the scope of a study. <br /> Typically factors include: the client's goals,objectives,and risk management preferences; the general nature of the structure <br /> involved,its size,and configuration;the location of the structure on the site;and other planned or existing site improvements, <br /> such as access roads, parking lots, and underground utilities. Unless the geotechnical engineer who conducted the study <br /> specifically indicates otherwise,do not rely on a geotechnical engineering report that was: <br /> • not prepared for you, <br /> • not prepared for your project, <br /> • not prepared for the specific site explored,or <br /> • completed before important project changes were made. <br /> Typical changes that can erode the reliability of an existing geotechnical engineering report include those that affect: <br /> • the function of the proposed structure, as when it's changed from a parking garage to an office building, or from a <br /> light industrial plant to a refrigerated warehouse, <br /> • elevation,configuration,location,orientation,or weight of the proposed structure, <br /> • composition of the design team,or <br /> • project ownership. <br /> As a general rule,always inform your geotechnical engineer of project changes,even minor ones,and request an assessment <br /> of their impact. Geotechnical engineers cannot accept responsibility or liability for problems that occur because their reports <br /> do not consider developments of which they were not informed. <br /> B.2.4 Subsurface Conditions Can Change <br /> A geotechnical engineering report is based on conditions that existed at the time the study was performed. Do not rely on a <br /> geotechnical engineering report whose adequacy may have been affected by: the passage of time;by man-made events,such <br /> as construction on or adjacent to the site; or by natural events, such as floods, earthquakes, or groundwater fluctuations. <br /> Always contact the geotechnical engineer before applying the report to determine if it is still reliable. A minor amount of <br /> additional testing or analysis could prevent major problems. <br /> 1 ASFE,8811 Colesville Road/Suite G106,Silver Spring,MD 20910 <br /> Telephone:301/565-2733:www.asfe.org <br /> Appendix B—Page 1 of 2 AMERICAN ENGINEERING TESTING,INC <br />
