Hennepin Pazks ' <br /> Project BABX-91-589 <br /> � December 19, 1991 <br /> Page 10 ' <br /> , <br /> . . . , <br /> noting the characteristics of the variations. The variations may result in addrtional construction <br /> costs, 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 <br /> the plans and specifications, it is recommended that we be retaine� to develop and perform ' <br /> the recommended observation and testing program for the excavation and foundation phases of <br /> the project. <br /> , <br /> If others perform the recommended observations and/or testing of construction, professional <br /> responsibility becomes divided since, in doing so, they assume responsibility for evaluating ' <br /> that the soil conditions throughout the construction areas are similar to those encountered in <br /> the borings or recognizing variations which require a change in recommendations. <br /> ' <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 greparation of this report. Because of the limited amount of information available, a <br /> number of assumptions were necessary to permit us to make recommendations. It is <br /> recommended that we be retained to review the final design and specifications to determine t <br /> whether those assumptions were correct and whether any change in concept may have had an <br /> effect on the validity of our recommendations, and whether our recommendations have been ' <br /> implemented in the design and specifications. If we are not permitted an opportunity to make <br /> this recommended review, we will not be liable for losses azising out of inconect <br /> assumptions, design changes, or 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 <br /> staterl on the boring logs. These data have been reviewed and interpretations made in the text ' <br /> of this report. However, it must be noted that the period of observation was relatively shoR <br /> and that fluctuations in the groundwater level may occur due to rainfall, flooding, inigation, <br /> spring thaw, drainage, seasonal and annual variations and other factors not evident at the time ' <br /> measurements were made and reporte� herein. Design drawings and specifications and <br /> construction planning should recognize the possibilities of variations. <br /> ' <br /> � <br />
