Merrill Creek Operations Base Main &Ops Bldg Exp Phase 3 Attn: John Wright 7000 Hardeson Road 707 S. Grady Way, Suite 120 use middle driveway off 7100 Hardeson Road Renton,WA 98057 Everett,WA Project Number: M7211390 Permit No.: B2101-003 EARTHWORK OBSERVATION Observed native subgrade conditions for the northwest and southeast corners of parking area, and subgrade below existing trench drain after removal at the Merrill Creek Community Transit Maintenance and Operations Base expansion located at 7100 Hardeson Road, Everett, WA. Construction documents referenced for today's inspection include Conformed plan set dated 06/18/21. Earthwork was performed by Fabor Construction. Native material exposed in northwest corner was grey and brown silty sand with gravel. We probed the entire area with a 1/2" diameter T-handled probe rod with minimal to no penetration. It is our opinion that the area probed is firm and unyielding, sufficient to support desired loads. Native material exposed in the southeast corner was brown silty sand with trace gravel. We identified a 3' by 6' area in the southeast corner as saturated and unconsolidated. We probed this 3' by 6' area with a 1/2" diameter T-handled probe rod with severe penetration. Contractor removed saturated material to depth of 2', placed filter fabric and quarry spalls, followed by a second layer of filter fabric and 1-1/4" crushed surface and base course. We probed the surrounding area in the southeast corner with T-handled probe rod with minimal to no penetration. The native material exposed surrounding the 3' by 6' area appears firm and unyielding, sufficient to support desired loads. Native material below trench drain removal was brown silty sand with trace gravel. We probed this entire area with 1/2" diameter T-handled probe rod with minimal penetration. It is our opinion the area below previous trench drain is firm and unyielding, sufficient to support desired loads. Results of today's inspection were reported to Forma Construction.
