Only final boring logs customarily are <br />included in geotechnlcal engineering reports. These logs <br />should not under any circumstances be redrawn for inclusion in <br />architectural or other design drawings. because drafters <br />may commit errors or omissions in the transfer process. <br />Although photographic reproduction eliminates this <br />problem, it does nothing to minimize the possibility of <br />contractors misinterprering the logs during bid prepara- <br />tion. When this occurs. delays. disputes and unantici- <br />~ted costs are the all-too-frequent result. <br />'f'o minimize the likelihood of boring log misinterpreta- <br />tion, give contractors ready access to the complete geotechnicaf <br />engineering report prepared or authorized for their use. <br />Those who do not provide such access may proceed un- <br />der r.hr mi: urttn imcression t-~t sr^pl~, disUaiming re- <br />;DOnSio:ht: inr the ac~racr cr ;ubsuriace information <br />always ir5~ ate5 .hem frcm at;encant liabihr/ Providing <br />:ne'oest;.;cable mforr•ancr.

This situation has resulted in wholly <br />unwarranted claims being lodged against geotechnlcal <br />ronsultants. To help pre':ent this problem, geotechnlcal <br />engineers ca':e developed mcdel clauses for use in wrio- <br />[en trar.smi::als. These are rua exculpatory clauses <br />designed to foist geotechnlcal engineers' liabilities onto <br />someone else Rather, [hey are definitive clauses which <br />identify where geotechnlcal engineers' responsibilities <br />begin and end. Their use helps all parties involved rec- <br />ognize their individual responsibilities and take appro- <br />priate action. Some of these definitive clauses are likely <br />to appear in your geotechnlcal engineering report. and <br />you are encouraged to read them closely Your geo- <br />technlcal engineer will be pleased to give Full and frank <br />answers to your questions. <br />OTHER STEPS YOU CAN TAKE TO <br />REDUCE RISK <br />Your consulting geotechnlcal engineer will be pleased to <br />discuss ocher techniques which can be employed to mit- <br />igate risk.
