EARTHWORK OBSERVATION REPORT <br />Report Number: M7231404.0013 <br />Service Date: 09/18/23 <br />Report Date: 10/17/23 <br />Client <br />Brixton Everett LLC <br />Attn: Kyle Godat <br />120 S Sierra Ave <br />Solana Beach. CA 92075 <br />® ierracon <br />20225 Cedar Valley Rd Ste 110 <br />Lynnwood, WA 98036-6365 <br />425-742-9360 <br />Project <br />Everett Mall Redevelopment <br />1402 SE Everett Mall Way <br />Everett, WA <br />Proiect Number: M7231404 <br />Loose Subgrade <br />- Moisture condition the exposed material and recompact using vibratory equipment. <br />- Dispatch Terracon to observe the subgrade following compaction. <br />Subcontractor machinery was observed to rut and disturb the exposed subgrade. It was suggested to Bayley <br />to wait until all subcontractor machinery has been demobilized from the tenant space before compacting the <br />exposed subgrade. <br />Bayley informed Terracon that a 2" crushed rock layer will be placed between the exposed subgrade and the <br />floor slab. We recommend performing the moisture conditioning and recompaction just before placing the <br />crushed rock. <br />Due to the potential for granular soils to lose moisture and loosen through regular construction activities, we <br />recommend Terracon be dispatched to observe the subgrade prior to casting concrete to confirm the subgrade <br />remains in a firm, non -yielding condition at the time of concrete pouring. <br />A Terracon representative will return to the site once dispatched by Bayley to observe the earthwork <br />recommendations conveyed herein. <br />Services: Special Inspections / Materials Testing <br />Terracon Rep.: Zachary Koehn <br />Reported To: Bayley Construction <br />Contractor: Bayley Construction <br />Report Distribution: <br />(1) Brixton Everett LLC, Kyle Godat (1) Bayley Construction, Tony Betz <br />(1) Mayes Testing Engineers, Inc, (1) Mayes Testing Engineers, Inc, <br />Donna Pollard Mike Mattox <br />Reviewed By: <br />Barry Tuttle <br />Project Field Manager <br />The tests were performed in general accordance with applicable ASTM, AASHTO, or DOT test methods.
