On December 11, 2001, a representative from Terracon observed the foundation excavation for
the referenced lot, as requested.
The soil conditions exposed within the upper foundation level consisted of sandy lean clay, and at
the lower foundation level claystone/bedrock was observed. These soil and/or bedrock conditions
are similar to those encountered in Earth Engineering Consultants Inc. (EEC) "Geotechnical
Engineering Report", project No. 1992129. Based on our observations, it is our opinion the
structure should be supported by a grade beam and straight shaft drilled pier/caisson foundation
system designed in accordance with the recommendations set forth in the EEC Geotechnical
Engineering Report.
At the time of the observation, no groundwater was encountered within two feet of the basement
foundation level. However, based on recommendations set forth in the EEC Geotechnical
Engineering Report, it is our opinion a dewatering system should be placed around the lower level
of the structure. The drainage system should be designed and constructed in accordance with the
recommendations set forth in the report.
