subsuitace conditions revealed during construction.The geolechnical engineer who developed your report cannot assume responsibility of liability toi the report's recommendations H thal engineer does not perform construction observation. A Geotechnical Englneering Report Is Subject to Misinterpretation Other design team members' misinterprelation ol geolechnical engineeling repofts has resulled in coslly problems. Lower mal risk by having your geo- technical engineer cooler with appropriate members of the design learn aller submitting tile report. Also retain your geolechnical engineer lo review perti- nent elements 01 the design team's plans and specifications. Contfactors can also misinterpret a geotechnical engineering report. Reduce Ihal risk by having your geotechnical engineer participate in prebid and preconstruction conferences, and by providing construction observation. Do Not Redraw the Engineer's Logs Geolechnical engineers prepare linal boring and testing logs based upon theit interpretation 01 field logs and laboralory dala. To preven! errors or omissions, the logs included in a geotechnical engineering report should never be redrawn lor inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk. Give Contractors a Complete Report anti Guidance Some owners and design professionals mistakenly believe they can make contractors liable loi unanticipated subsurface conditions by limiting what Ihey provide for bid preparation. To help prevenl costly problems, give con- tractors the complete geotechnical engineering report, but preface it with a clearly written letter of transmittal. In that teller, advise contractors thal the report was not prepared 101 purposes of bid development and that the report'S accuracy is limited: encourage Ihem to conler wilh the geotechnical engineer who prepared the report (a modest lee may be required) and/or to conduct additional sludy to obtain the specitic types of information Ihey need or prefer. A prebid confeience can also be valuable.Be sure contrac- tog have su#icient time lo perform additional study. Only then might you be in a position to give contractors the best infommtion available to you, while requiring them to at leasl share some 01 the financial responsibilities stemming [fom unanticipated condilions. Reall Responsibility Provisions Closely Some clienls, design professionals, and contractors do not recognize that geotechnical engineering is far less exact than other engineering disci- plines. This lack of understanding has created unrealistic expectations thal have led to disappointments, claims, and disputes. To help reduce the risk 01 such outcomes, geotechnical engineers commonly include a variety of explanatory provisions in their reports. Sometimes labeled *limilations' many 01 these provisions indicate where geotechnical engineers' responsi- bilities begin and end, to help others recognize meir own responsibilities and risks.Read these provisions closely. Ask questions. Your geotechnical engineer should respond lully and frankly. Geoenvironmental Concerns Are Not Covered The equipment techniques, and personnel used to perform a geoenviron- menM/study ditler significantly from those used to perlorm a geolechnical study. For that reason, a geotechnical engineeiing report does not usually relale any geoenvironmental lindings, conclusions, or recommendations; e.g,, about tile likelihood 01 encountering underground storage tanks or regulated conlaminants. Unantic08/ed environmental prob/ems have led to numefous project /al/ums. If you have not yel obtained your own geoen- vironmental information, ask your geolechnical consultant lor risk man- agemen\ guidance. Do not rely on an environmental report prepafed lor someone else. Obtain Professional Assistance To Deal with Mold Diverse strategies can be applied during building design, construction, operation, and maintenance to prevent significant amounts ot mom from growing on indoor surlaces. To be enective, all such strategies should be devised lor the e,wress purpose of mold prevention, integrated into a com- prehensive plan, and executed with diligenl oversight by a prolessional mold prevenlion consultant. Because just a small amount of water or moislure can lead to the development ol severe mold inlestalions, 3 num- ber 01 mold prevention strategies locus on keeping building surlaces dry. While groundwater, water infiltration, and similar issues may have been addressed as part of the geotechnical engineering study whose findings are conveyed in this report,tile geolechnical engineer in charge 01 this project is not a mold prevention consultant; none of the se,Wces per- formed in connection with the geotechnical engineer's study were designed or conducted for the purpose 01 mold preven- lion. Proper implementation of the recommendations conveyed in this report will not of itself be sufficient to prevent mold from growing in or on the structure involved.
