Project No. D-3885-06 <br />Christ Our Savior Catholic Parish <br />During excavation of the pad, it is possible to have a high moisture content bottom in <br />yielding condition due to the shallow water table and depending on the time of grading. <br />To stabilize the base of deeper excavations or to replace sloughed materials close to the <br />groundwater level, special measures may be needed if purnping or other problems are <br />encountered. These may include the use of 2-sack cement slurry backfill in localized <br />areas, impo( crushed rock type materials, filter fabric, or other measures as may be <br />appropriate. To address such conditions, the Geotechnical Engineer should be consulted <br />during construction. <br />General Geotechnical Observations: <br />At a minimum, we recommend that the Ceotechnical Consultant representative be present <br />to observe and provide testing during the following construction activities: <br />- Pre-grade meeting; <br />- During Compaction Grouting; <br />- Excavations for compacted fill; <br />39 <br />Construction observation and fieldtesting services are an essential continuation of our <br />prior studies to confirm and correlate our findings and recommendations with the actual <br />subsurface conditions exposed during construction, and to confirm that suitable fill soils <br />are placed and properly compacted. It should be the Contractor's responsibility to notiff <br />the project Geotechnical Consultant at appropriate times for observation. A representative <br />of the project Geotechnical Consultant should be present on site during all major grading <br />operations to veriry proper placement all deep foundations and adequate compaction of <br />all fills, as well as to veri$ compliance with the other recommendations presented herein. <br />- Observations of subgrade compaction; <br />- Backfilling of utility trenches, pits, and trenches following demolition;
