BRAUN <br /> DAILY OBSERVATION REPORT NTE BTEC <br /> Project c BL-08-02099'C Report#: <br /> Location: Myrtle G.Schumann Elementary School Date: June 2, 2010 <br /> Personnel Classification Regular Hours Overtime Hours <br /> Bryan Field Staff Engineer <br /> Areas and work performed this day: <br /> Requested by Kraus Anderson to perform a soil evaluation for a utility trench located in the electrical room of the Myrtle <br /> G.Schumann Elementary School. Upon arrival,the slab-on-grade was saw cut and soil was removed in the trench down <br /> approximately 2 feet from the top-of-slab elevation.The soil removed from the trench was stock piled adjacent to the <br /> trench.The stockpiled soil was visually classified as a dark gray to dark brown lean clay in a saturated to over saturated <br /> state.Two hand auger probes were performed to depths of 3 feet below the trench bottom. Below the couple inches of <br /> oversaturated"slop"clay,the soils consisted of gray lean clay that was judged to have a consistency of medium to rather <br /> stiff based on the turning resistance of the hand auger and considered suitable for slab and electrical utility trench backfill <br /> support. <br /> After performing the hand auger probes and the visual classification of the stockpiled soil,it was recommended that the <br /> remaining"slop"be removed from the trench and a clear rock placed to form a stable working platform for the utility crew. <br /> In its existing condition,the stockpiled soil from the trench was over saturated and appears unsuitable for use as a <br /> backfill material. It was recommended a suitable material that can be compacted be imported and used as trench backfill <br /> in-lieu of the stockpiled soil. <br /> Weather: Mostly Cloudy—60's Performed By: Bryan Field <br /> Submitted To: Brandon Larkin(Kraus Anderson) <br /> c: <br /> frm\daily obser rev form <br />
