We previously performed. a density test on the final lift (top 12" of fill soils). The purpose of this investigation was to evaluate the of structural fill to determine if the fill soils were properly compacted. The site. investigation program consisted of performing four (4) soil profiles, each to a depth of 6 feet with. static cone penetrometer readings. During the test, a shaft with a conical point is pushed through the soil and the thrust required to push the cone tip is measured on an attached calibrated gauge. The value of the bearing pressure exerted by the cone point allows the operator to estimate the existing soil density. After the thrust was measured, the hole was advanced with a hand -auger in 1-foot increments to permit a continuation of measurement of relative density versus depth. Based on the information obtained from this site investigation, we are pleased to offer the following evaluation: The boring logs indicate the subsurface soils consist mostly of fine grained sand and fine-grained sand with some clay. No 'muck' or other unsuitable soils were encountered in the test. Static cone penetrometer readings recorded during the investigation indicates that the existing soil density is generally medium -dense. Please refer to the soil boring logs for specific information relative to the soil description. i Ronald G: Keller, P.E.: 37293 / SI Lic. No.: 860 / Julie E.

Closure: This report has been prepared in accordance with generally accepted soil and foundation engineering practices based on the results of the nuclear density tests and static cone penetrometer readings. This report does not reflect any variations which may occur, between the borings. If variations appear evident during the course of construction, it would be necessary to re-evaluate the recommendations of this project.
