ASFE/The Assbdation of Engineering Firms Practici ng in the Geosciences offers the following suggestiahs and observations to help yon manage your asks. 4 7W A GEOTECHNICAL ENGINEERING REPORT IS BASAD ON A UNIQUE SET OF PROJECT -SPECIFIC FACTORS - Your geotechnical engineering report is based on a subsurface exploration pian designed to consider a unique set of project -specific faCCors. These factors typically include: the general nature of the structure . _ involved. its size, and configuration; the location of the stricture on the site; ether improvements, such as access roads, parking dots, and underground utilities; and the additional risk crewed by scope -of -service limitations imposed by the client. To help maid costly problems, ask your geotechnical engineex to evaluate how factors that change subsequent to the date of the report may affect the report's recommendations. Unless your geotechnical engineer indicates otherwise, do not use your geotechnical engineering report: When the nature of the proposed structure is changed, for example, if an office building will be erected instead of a parking garage, or a refrigerated warehouse will be built instead of an unrefrigerated one; • When the size, elevation, orconfiguration of the proposed structure is altered; 0 When the location or orientation of the proposed stricture is modified; * when there is a change of ownership; or ■ dor application to an adjacent site. Y Geotechnical engineers cannot accept responsibility for problems that may occur if they are not consulted ager factors considered in their report's develoPment have changed - SUBSURFACE CONDITIONS CAS CHANGE A geotechnicaI engineering report is based on condi- tions that existedat the time of subsurface exploration. Do not base construction decisions on a geotechnical engineering report whose adequacy may have been effected by time. Speak with your geotechnical consult- ant to learn if additional tests are advisable before construction starts.Uote, too, that additional tests may be required when subsurface conditions are affected by construction operations at or adjacent to the site, or bv " natural events such as floods, earthquakes, or ground water fluctuations. Keep your geotechnical consultant apprised of any such events. :l :ill l ll &1C 11 Cl!! 16 1 A MAST GEOTECHNICAL FINDINGS ARE PROFESSIONAL. JUDGMENTS Site ex'plaratfon identifies actual subsurface conditions. only at thane points -where samples ar'e�-taken. The--data- were extrapolated by yaur�eotechnica# engineer who then applied judgment to render an opinion about overall subsurface conditions_ The actual interface between materials may he Far more gradual or abrupt than your report indicates. actual conditions in areas not sampled may differ from those predicted in your report. While nothing can be doge to prevent such situations, you and your geotechnical engineer can work together to help minimize their impact. Regaining your geotechnical engineer to observe construction can be particularly beneficial in this respect. A REPORT'S RECOMMENDATIONS CAN ONLY BE PRELIMINARY The construction recommendations included in your geotechnical engineer's report are preliminary, because they must be based on the assumptionthat conditions revealed through selective exploratory sampling are indicative of actual conditions throughout a site. Because actual subsurface condi'tions can be discerned only during earthwork, you should retain your geo- technical engineer to observe actual conditions and to finalize recommendations- Only the geotechnical engineer who prepared the report is fully familiar with the background information needed to determine wether or not the report's recommendations ars valid and whether or not the contractor is abiding by appli- cable recommendations. The geotechnical engineer who developed your report cannot assume responsibility or liability for the adequacy of the report's recommenda- tions if another party is retained to observe construction. GEOTECHNICAL SERVICES ARE PERFOIZMED FOR SPECIFIC PURPOSES AND PERSONS Consulting geotechnical engineers prepare reports to meet the specific needs of specific individuals. A report prepared dor a civil engineer nay riot be adequate for a construction contractor or even another civii engineer. Unless indicated otherwise, your geotechnical engineer prepared your report expressly for you and expressly for purposes you indicated. X10 one other than you should apply this report dor its intended purpose without first conferring with the geotechnical engineer. No party should apply this report for any purpose other than that originally contemplated without first conferring with the geotechnical engineer.
