The variations may result in additional foundation costs, <br /> and it is suggested that a contingency be provided for this purpose. <br /> To permit correlation of the soil data obtained to date with the actual soil conditions <br /> encountered during construction and to provide continuing professional responsibility for the <br /> conformance of the construction to the concepts originally contemplated in this report and to the <br /> plans and specifications, it is recommended that we be retained to develop and perform the <br /> recommended observation and testing program for the excavation and foundation phases of the <br /> project. <br /> If others perform the recommended observations and/or testing of construction, professional <br /> responsibility becomes dividetl since, in doing so, they assume responsibility for evaluating that <br /> the soil conditions throughout the construction areas are similar to those encountered in the <br /> borings or recognizing variations which require a change in recommendations. <br /> F.2 Review of Design <br /> This report is based on the preliminary design of the proposed structure as submitted to us for <br /> the preparation of this report. Because of the limited amount of information available, a number <br /> of assumptions were necessary to permit us to make recommendations. It is recommended that <br /> we be retained to review the final design and specifications to determine whether those <br /> assumptions were correct and whether any change in concept may have had an effect on the <br /> validity of our recommendations, and whether our recommendations have been implemented in <br /> the design and specifications. If we are not permitted an opportunity to make this recommended <br /> review, we will not be liable for losses arising out of incorrect assumptions, design changes, or , <br /> misinterpretation or misapplication of our recommendations. <br /> F.3 Groundwater Fluctuations <br /> Water level readings have been made in the borings at the times and under the conditions stated <br /> on the boring logs. These data have been reviewed and interpretations made in the text of this <br /> report. However, it must be noted that the period of observation was relatively short and that <br /> fluctuations in the groundwater level may occur due to rainfall, flooding, irrigation, spring <br /> thaw, drainage, seasonal and annual variations and other factors not evident at the time <br />
