The percentage oi p� ticles passing the No. 200 sieve <br />should be measured irom that portion of soil passing the three•q� 3rter-inch sieve. <br />LIMITA710NS <br />The conclusions and recommendations coniained in this report are based on site conditions as <br />they existed at the time oF our exploretion and assume thal the soil and groundwater conditions <br />encountered in the test borings are representative of subsuria�e conditions on ihe site. If the <br />subsur.'ace conditions encountered during consiruclion are sgnificantly di(ferent irom those <br />observed in vu explorations, we shouid be advised at once so th� t we can review these conditions <br />and reconsider our recommendations �vhere necessary. Ur anticipated soil conditions are <br />commonly encountered on construction sites and cannot be fully anticipated by merely taking soil <br />samples in test borings. Subsurface conditions can also vary betv een exploralion locations. Such <br />unexpecfed conditions frequently require making additional ex �onditures to attain a properly <br />constructed projecl. it is recommended thal ihe rnvnei consider �roviding a contingency fund to <br />acr�mmodate such potenlial extra costs and risks. This is a s andard recommendation for all <br />projects. <br />This report has been prepared For the exclusive use o` the Ev rett Housing Authority and its <br />representatives, for specific application to this project and site Our recommendalions �nd <br />conclusions are based on observed site material� and enqineering analyses.
