� CNA Architecture Group 12 April 1991 6.0 CLOSURE � W-7352 Page 14 Based upon our field and office studies, it is our opinion that it would be feasible from a geotechnical standpoint to construct the proposed building at this location. The building may supported by conventional !ootings which be�r upon the medium dens�s to dense naturally occurring sands or compacted structural fill. Special attention to wet weather construction techniques would be required due to the silty nature of the onsite fill soils. The conclusions and recommendations presented in this report are based. on the explorations accomplished for this study. The number, location, and depth of the explorations were completed within the site and proposal constraints so as to yield the information utilized to formulate our recommendations. The future integriry of the building foundations depending upon proper site preparation and construction proCedures. Due to the variable subsurface conditions observed, it appears that at this time that some judgement will be necessary in the field to determine the adequacy of the fill material and foundation support system. It is especially critical that a uniform pad of compacted fill be provided in order to minimize abrupt differential settlements. Therefore, because of our familiarity with the soils, we recommend that Rittenhouse- Zeman & Associates, Inc., be retained to provide geotechnical engineering services during the earthwork and foundation construction phases of the project. If variations in the subsurface conditions are observed at the time, we would be able to provide additional geotechnical engineering recommendations in a timely manner. �� s N N
