Ideally, structural fill that will be placed in wet weather should consist of a coarse, granular soil with a silt or clay content of no more than 5 percent. The percentage of particles passing the No. 200 sfeve should be measured trom that portion of soil passing tha three-quarter- inch sieve. 'i'he on•site soils are suitable for structural fill. Howe��er, the sands can be diHicult to compact due to their grain-size distributlon. LLMIL[ATIONS The analyses, conclusions, and recommendations conteined in this report are based on site conditions as they existed at the time of our expioratior: and assume tFiat the soils encoun- tered in the test pits are representative of subsurfece conditions on the site. If the subsurface conditions encountered during construction are significantly ditterent from those observed in our explorations, we should be advised at once so that we can review these conditions and reconsider our recommendations where necessary. Tliis report has been prepared for the exclusive use of Thomas Kelly and fiis ' representatives tor specific application to this proJact and site. Our recommendations and � conclusions are based on observed site materfds, and selective laboratory testinc� and engineering analyses. Our conclusions and recommendations are professional opinions derived fn accordance wi,h current standards of practice within the scope of our services and within budget and time constraints. No warranty is expressed or implied. The scope of our services does not include services related lo construction safety precautions, and our 'I recommendations are not intended to direct the �ontractor's methods, techniques, sequances, or procedures, except as speciticaliy described in our report for consideration fn GI:O'lliCll CONSULIANII,ING
