The web is a bolted connection with a splice plate and the outside pile flanges are shown to welded with a 5/16" bevel weld. Inspected the fit -up prior to welding and advised the contractor that the bevel size needed to be increased to provide the 5/16" fillet. This bevel was ground with a grinder as required. Inspected the weld after completion and cooling and found the welding was visually acceptable per AWS D1.1 visual inspection criteria. This was for the southern -most "H" pile. To the best of our knowledge, the items inspected today are in conformance with approved plans and specifications.

The reinforcing steel was inspected prior to placement for proper spacing, grade, size, lap splice lengths, clearances and cleanliness. All reinforcement appeared to conform to the provided specifications, plans, RFI's and details B, C and D/S3.2 and A/S4.1. At the transition between pile cap sections (details B/S3.2 and D/S3.2), the top horizontal #5 bars need to be installed through the construction joint to provide the lap splice development into the next phase of the pour. This was completed before concrete placement. Concrete was properly placed using a pump truck, then mechanically consolidated using a vibrator. During testing, the slump was observed at 8" at the truck chute, which is high (6" specified); but added water was in tolerance, and the City Inspector and concrete foreman were notified. The temperature of the concrete was 760, and air was measured at 5.1 %. One (1) set of (5) 4x8" cylinders was cast for compressive strength testing (f'c 5000 psi at 28 days). To the best of our knowledge, the items inspected today are in conformance with approved plans and specifications.

Upon arrival at the site, it was noted that the material to be used as backfill for the radiused retaining wall was visually classified as imported gray sand with gravel (CalPortland Type 17). (See Mayes Testing Engineers (MTE) Laboratory Compaction Characteristics of Soil Report 0016A, service date 06/01/20). The fill material was observed to be adequately moisture conditioned and was placed in loose lifts approximately 12" to 18" thick. Compaction efforts were applied utilizing a Komatsu PC138US excavator with a vibratory hoe -pack attachment. At the time MTE departed, the contractor was planning on placing a second lift on the south end when more fill material was received. The first lift was tested and passed at 2' below grade. All lifts observed today appeared firm and stable during compaction efforts. Field density tests were performed utilizing nuclear method ASTM D6938. The test results met the minimum specified compaction requirement of 95% and 90% within 3' of the retaining wall, per recommendations by geotechnical engineer Sean Gertz (Landeau Associates) provided via email. Refer to the attached Soil Field Density Test Report for individual test data. To the best of our knowledge, the items inspected today are in conformance with approved plans and specifications.

The reinforcing steel was inspected prior to placement for proper spacing, grade, size, lap splice lengths, clearances and cleanliness. All reinforcement appeared to conform to the provided specifications; plans; RFI's 31, 34 and 35; details B/S3.2 and A/S-2.4; and details on SK-05. The concrete was properly placed using the truck chute, then mechanically consolidated using a vibrator. During testing, the slump was observed at 6" at the truck chute. The concrete temperature was 75°F, and the air entrainment was measured at 4.8%. One (1) set of (5) 4x8" cylinders was cast for compressive strength testing (f'c 5000 psi at 28 days). To the best of our knowledge, the items inspected today are in conformance with approved plans and specifications.

WG Clark Construction Company performed the earthwork activities. Soil Fill Placement Observation At the time of arrival, noticed the material to be used as fill at the area was import material visually classified as recycled concrete. Material was observed to be adequately moisture -conditioned and placed in lifts approximately 1' thick. Compacting efforts were applied utilizing a HoPac and hand plate compactor. The fill placed was observed to be firm and stable after the compaction efforts. Field density tests were conducted utilizing a nuclear density gauge. The test results met the minimum specified compaction requirement of 95%. Refer to the attached Field Density Test Report for individual test data, To the best of our knowledge, the items inspected today are in conformance with approved plans and specifications.

Per the General Notes on S1.2, #5 bars are to be epoxy anchored with 7" of embedment. Upon inspection, it was noted that the holes were 6" deep. Asked Dylan with WG Clark Construction about this; and he stated that he directed the installer to drill 6" so that the back of the wall would not blow out during drilling, which does occur when the holes are drilled too close to the outside face of the wall. Noted that the hook bars anchored at the bottom of the stairs were 7-1/2" deep. All holes were brushed and blown clean, as required. Hilti HIT-HY 200 (lot 1452 24 L2, expiration 06/2021) was used for the installation. The holes were filled, and the reinforcing steel bars were installed. PRELIMINARY INSPECTION The engineer should review the reduced embedment for acceptance prior to concrete placement. Dylan has made contact with the engineer and is waiting for a response.

Dylan (WG Clark Construction) was informed, and the engineer -of -record (Chris Halamek) responded on 09/17/20 with acceptance of the lesser 6" embedment depth referenced in MTE inspection report 0031. MTE preliminary inspection report 0031, service date 09/01/20, is now closed. To the best of our knowledge, the items inspected today are in conformance with approved plans and specifications.

Clark Construction Potential Cost Impact: See attached for a Mayes inspection report for the south stair rebar on 9/1. The inspector called out the following... Inspected the holes drilled for the epoxy anchoring of #5 reinforcing steel bars into the south stair walls for the steps. Per the General Notes on S 1.2, #5 bars are to be epoxy anchored with 7" of embedment. Upon inspection, it was noted that the holes were 6" deep. Asked Dylan with WG Clark Construction about this; and he stated that he directed the installer to drill 6" so that the back of the wall would not blow out during drilling, which does occur when the holes are drilled too close to the outside face of the wall.

The FiveStar DP Epoxy Grout was approved by email on 10/06/20 from project engineer, Blaine McRae, prior to anchor installation, and was prepared according to manufacturer's specifications. The resin lot number was 5249651970, the hardener lot number was 5251702020 and the aggregate lot number was 21 FG-FIV-05008. The (18) 3" diameter holes were drilled according to plan details (S3.2) with a depth of 12" +/- 3", meeting minimum embedment depth of 8", according to plan details (S3.2). The holes were also drilled 12" +/- 3" on center apart according to plan details (S3.2). The holes were roughened, cleaned and dried according to manufacturer and project specifications, as well as possible considering environmental conditions, prior to anchor installation. Epoxy -coated #6 bars were installed into bulwark prior to inspection. The 3" diameter holes were then filled with FiveStar DP Epoxy Grout immediately prior to bulwark installation. The bulwark was then lifted and placed by forklift with each of the epoxy -coated #6 bars inserted into each 3" diameter hole, meeting the minimum 8" embedment depth (S3.2).

Upon arrival at site, spoke with WG Clark, Dylan, about re -compacting the base course subgrade disturbed by equipment traffic prior to today, and observed some finishing of a little base course material grading including re - compaction at the Waterfront Redevelopment side of the new asphalt paving lots. Mayes Testing Engineers inspector, Keith Bellows, sampled 1/2" minus HMA material from the Cadman - Woodinville plant for extraction and gradation. Was informed by Keith, this morning, of a 157.4 pcf for the Rice value unit weight. Ran in -place asphalt field density compaction tests today at the paved parking lots at the Edmonds Senior Center and adjoining the City of Edmonds Waterfront Redevelopment projects. Nuclear density tests indicate compaction effort by a 1.5-ton and a 5-ton roller meet the 91 % minimum compaction requirement. Asphalt temperature range as delivered was between 265°F and 338°F. See attached Asphalt Field Density Test Report for additional information. Returned the nuclear gauge to the Lynnwood, WA lab at end of day per WSDOT requirement.
