Aulik Associates <br /> Project BL-04-06716 <br /> October 11,2004 <br /> . Page 11 <br /> E.3. Groundwater Observations <br /> Ixnmediately after taking the final samples in the bottoms of the borings, the holes were probed through <br /> the hollow-stem auger to check for the presence of groundwater. Immediately a,fter withdrawal of the <br /> auger,the holes were again probed and the depths to water or cave-ins were noted. The borings were <br /> probed again and backfilled just prior to leaving the site. <br /> F. General Conditions . <br /> F.1. Basis of Recommendations <br /> The analyses and recommendations submitted in this report are based upon the data.obtained from the <br /> soil borings performed at the locations indicated on the attached sketch. Often,variations occur between <br /> these borings,the nature and extent of which do not become evident until additional exploration or <br /> construction is conducted. A reevaluation of the recominendations in this report should be made after <br /> performing on-site observations during construction to note the characteristics of any variations. The <br /> variations may result in additional foundation costs,and it is suggested that a contingency be provided <br /> for this purpose. <br /> It is recommended that we be retained to perform the observation and testing program for the site <br /> preparation phase of this project. This will allow correlation of the soil conditions encountered during <br /> construction to the soil borings, and will provide continuity of professional responsibility. <br /> F.2. Review of Design <br /> T'his report is based on the design of the proposed cazriage home as related to us for preparation of this <br /> report. It is recommended that we be retained to review the geotechnical aspects of the designs and <br /> specifications. With the review,we will evaluate whether any changes in design have affected the <br /> validity of the recommendations, and whether our recomtnettdanons have been correctly interpreted and <br /> implemented in the design and specifica�ions. <br /> F.3. Gronndwater Fluctuations <br /> We made water level observations in the borings at the tirnes and under the conditions stated on the <br /> boring logs. These data.were interpreted in the text of this report. 'The period of observation was <br /> relatively short, and fluctuations in the groundwater level may occur due to rainfall, flooding,irrigation, <br />
