City of Edmonds Permit # BLD2021-0815
Dear Ms. Carter,
Zipper Geo Associates, LLC (ZGA) provided geotechnical construction observation services for the Point
Edwards Condominium's Building 71 Pedestrian Bridge Abutment Foundation Repair Project located at 93
Pine Street in Edmonds, Washington. Our site observations and recommendations have been summarized
in Daily Field Reports (DFRs) 1 through 5, which have been transmitted to you, the structural engineer, and
the contractor over the course of the construction. ZGA was designated geotechnical "special inspector"
by the City of Edmonds in an undated Special Inspection and Testing Agreement letter. Our responsibilities
included:
• Monitor Driven Pipe Pile Installations - ZGA monitored the installation of all six production pipe
piles. Pile and pile bracket components were observed to be in general accordance with the project
plans and alternates approved by the structural engineer. The pipe piles were installed to relatively
consistent depth and refusal values.
• Monitor Pile Load Test - One production pile was load tested to 200 percent of the design load in
general accordance with ASTM D 1143-07. The test pile appeared to be representative of the other
production piles and suitable for load testing, in our opinion. Test results indicated an ultimate
capacity of at least twice the design load in accordance with project requirements. Based on our
installation observations and the results of the load test, it is our opinion that the production pipe
piles have been installed in general accordance with the approved plans and are adequate to
support the design axial compressive load.
• Monitor Pile Bracket and Adhesive Anchor Bolt Installation - ZGA monitored the installation of the
adhesive anchor bolts and brackets for all six piles. The anchor bolts and brackets were installed in
general accordance with the manufacturer's directions, the project plans, and recommendations
of the project structural engineer.

• Monitor Corrosion Protection Coating Installation - ZGA observed that the pile brackets and the
exposed portions of the anchor bolts were covered with an approved corrosion protection coating
of asphalt emulsion. Based on our observations, the corrosion protection coating installation
appeared to be in general accordance with the approved plans.
Based upon our observations, the contractor completed the tasks described in the City approved plans
under City of Edmonds Permit No. BLD2021-0815 and also implemented recommendations made by the
project geotechnical engineer and structural engineer during construction which reflected field -
adjustments to meet site conditions.

We visited the project site at 8:40 am at the request of the contractor and on behalf of the owner to observe the
installation of pipe piles. A summary of our observations, recommendations, and conclusions is presented below.
Upon arrival, we observed that the earthwork contractor Waeco Construction LLC had cored four 4-inch diameter holes
through the Building 71 abutment concrete footings at the approximate pipe pile locations shown on the approved plans.
The approved plans indicate that pipe piles shall be driven to substantial refusal with a 350-pound rated hammer (actual
hammer weight 400 pounds), with refusal defined as less than 1 inch of penetration for 30 seconds of driving. The pile
contractor Seattle Foundation Repair (SFR) indicated that the hammer delivered to the site was a 900-pound hammer and
not a 350-pound hammer. The hammer weight was not indicated on the equipment and SFR had no supporting
documentation on site. SFR asked ZGA what the refusal criteria was for a 900-pound hammer. We informed SFR that it
was the contractor's responsibility to install the piles to an allowable design axial capacity of 12 kips per pile in accordance
with the approved plans and that refusal can vary based on equipment used and its efficiency. Ultimately, the capacity of
the piles will need to be verified by the contractor via load testing in accordance with the approved plans. We informed
SFR that in our experience other contractors have used a refusal criteria of less that 1 inch of penetration in 10 seconds of
driving with an 850-pound hammer for 3-inch pipes with a 12 kip allowable capacity. SFR elected to use a refusal criteria
of less than 1 inch of penetration during 20 seconds of driving with the onsite hammer reportedly rated at 900-pounds.
We observed SFR drive three piles to the refusal criteria of less than 1 inch of penetration during 20 seconds of driving
with the hammer reportedly rated at 900-pounds. Pile locations, drive depths, and penetration rates at refusal are
presented in the table below.

Project: Point Edwards Condos Date: 01.07.2022
While attempting to drive the fourth pile (NW pile location on Building 71 abutment), the pile impacted and broke what
appeared to be a 3 to 4 -inch water pipe (reportedly associated with the building fire suppression system) at a depth of
about 5 feet below the top of footing. Work on pipe pile installation stopped for the day and an effort was started to shut
off and fix the broken water pipe. Water filled the abutment footing excavation, and some water overtopped the concrete
retaining wall to the north before the water was turned off. The water was turned off before reaching the condominium
building. At about noon, a representative with Charter Construction indicated that no further pile work would be
completed today and that ZGA would be contacted to schedule resumption of work.
SFR used 10-foot sections of 3-inch diameter, Schedule 40, Grade A, galvanized steel pipe based on manufacturer stamps
on the pipe. Galvanized steel compression couples were used to joint pipe sections. The project plans specify the use of
3-inch diameter, extra strong, ASTM A53 (standard 02, 2022 current) Grade B, FY=35,000 PSI, galvanized steel pipe. After
review of steel pipe classifications, ZGA determined that the Schedule 40 steel pipe provided by the contractor was not
consistent with the project requirement for extra strong pipe. Extra strong pipe is Schedule 80 (thicker wall section). We
informed the contractor and project structural engineer Pacific Engineering Technologies (PET) regarding the discrepancy
in pipe pile material. PET determined that the Schedule 40 pipe delivered to the site would be an acceptable substitution
provided a total of 6 piles are installed to support the abutment instead of four as shown on the plans. Charter
Construction took field measurements of site conditions including the location of the repaired water pipe and coordinated
locations for the fourth planned pile and two additional piles with PET and ZGA. Recommendations for the remaining 3
piles for the Building 71 abutment provided by PET via email are presented below.
The pile that previously struck the underground pipe should be relocated and installed at 4.5 feet from the
sidewalk end of the abutment.
Two additional piles shall be installed 1 foot away from the other piles and closer to the building, one on each
side (6 total piles). The brackets should be raised up and bolted to the concrete above the adjacent brackets.
It is acceptable to use galvanized schedule 40 pipe.

was a reduction in the refusal criteria of less than 1 inch of penetration during 20 seconds of driving used by SFR to install
piles P1 through P3 at this abutment on 01-07-2022.
We observed SFR drive three piles to the refusal criteria of less than 1 inch of penetration during 15 seconds of driving
with the hammer reportedly rated at 900-pounds. Pile locations, drive depths, and penetration rates at refusal are
presented in the table below. Note that pile P4 was in conflict with a utility and was cut off and abandoned in place
without being attached to the abutment.

SFR used 10-foot sections of 3-inch diameter, Schedule 40, Grade A, galvanized steel pipe based on manufacturer stamps
on the pipe. Galvanized steel compression couples were used to joint pipe sections.
While onsite we observed the SFR planned to use Simpson Strong -Tie SET-XP epoxy for the pile bracket anchor bolts and
that this material did not match the plan specifications, which require Simpson Strong -Tie AT-XP. We later spoke with the
project structural engineer Mr. Kyle Bozick about this change, and Mr. Bozick indicated that SET-XP was not an approved
substitution. We also spoke with Mr. Bozick about SFR's plan to react against the existing pedestrian bridge abutment for
the load test using 5/8x4 SB+ bolts to attach the load test bracket to the foundation. Mr. Bozick indicated that PET has not
completed engineering calculations for the referenced 5/8-inch bolts and recommended that the load test setup use the
plan specified 3/ inch epoxied tread bar.

We visited the project site at 11:40 am at the request of the contractor and on behalf of the owner to observe the
installation of epoxy anchor bolts and monitor a load testing on pile P5. A summary of our observations,
recommendations, and conclusions is presented below.
Pile Load Test
Upon arrival, we observed that Seattle Foundation Repair (SFR) was setting up to complete a load test on pile P5 (pile
location shown in Figure 1 of this report). Pile P5 was driven to a refusal criteria of less than one inch of penetration during
15 seconds of sustained driving with a 900 pound hammer and to a depth of about 15% feet below the top of the
foundation. Based on our pile installation observations, it is our opinion that pile P5 is representative of the other Building
71 abutment piles and is suitable for pile load testing.
SFR used a Power Team cylinder and pump with a Wika pressure gauge that had current calibration results and matching
certificate numbers of 359828381 by Jacking Solutions. SFR used a production bracket and four % inch epoxied bolts to
secure the bracket to the pedestrian bridge for the load test. SFR set up a dial gauge that was mounted on a support that
was independent of the test pile and abutment. A pressure gauge was placed in line to the cylinder to read the pressure
that the cylinder. A laser level was used to monitor the abutment foundation for possible movement during the load test.
Pile P5 was loaded in 25 percent increments to a maximum test load at 200 percent of the design load (12 kip allowable
design load) in general accordance with the Standard Test Method for Piles under Static Axial Compressive load, Quick
Load Test Method for Individual Piles (ASTM D1143). A plunging failure was recorded at about 175 percent of the design
load of 12 kips. No movement of the abutment was observed during the load test. Pile acceptance was determined in
accordance with Figure 6 of the Navel Facility Engineering Command Foundations & Earth Structures, Design Manual 7.02.
The pile contractor thought the failure may have been due to a misreading of the displacement dial gauge. At the
contractor request, we repeated the load test and got similar results. The results of the first and second load test on pile
P5 are presented below.
Based on our pile installation observations and the load test results, it is our opinion that piles P1, P2, P3, P5, P6, and P7
at the abutment for Building 71 are adequate to support an allowable design load of 10.5 kips per pile with a safety factor
of at least 2. Pile P4 was abandoned in place and not used for abutment support. We contacted the project structural
engineer Mr. Kyle Bozick with Pacific Engineering Technologies and relayed our findings and opinion regarding the

Pile Bracket Anchor Bolts
After the pile load tests, we prepared to monitor the installation of pile bracket anchor bolts. We observed that the
contractor had replaced the out -of -spec Simpson Strong -Tie SET-XP epoxy previously delivered to the site with Simpson
Strong -Tie AT-XP acrylic adhesive in accordance with the project plans and specifications. We also noted that most of the
holes for the bracket anchors had been drilled prior to our arrival. We noted that the anchor holes were drilled with a 7/8-
inch bit. This does not comply with the manufacture's recommendations for Simpson AT-XP with %-inch diameter
threaded bar. The manufacturer requires a 13/16-inch bit. We contacted Simpson to determine if a 7/8-inch diameter
hole was acceptable. The engineering group at Simpson indicated that the oversized hole could result in a reduced anchor
capacity and is not considered acceptable. We also noted that the contractor did not have the "Piston Plug" installation
pack for horizontal and overhead anchorage, as recommended by Simpson. Other Simpson Adhesives were considered
for use with the existing 7/8-inch holes and 3/-inch threaded rod, but did not appear applicable given the current
temperatures in the mid 30's to mid 40's Fahrenheit. We understand that the contractor plans to discuss possibly shifting
the brackets up a few inches and redrilling the appreciate diameter anchor holes with the project structural engineer.

We visited the project site at 11:00 am at the request of the contractor and on behalf of the owner to monitor the
installation of adhesive anchor bolts for the pile brackets at the Building 71 pedestrian bridge abutment. A summary of
our observations, recommendations, and conclusions is presented below.
Pile Brackets
Pile brackets consisted of 5/8-inch steel plate with X-inch fillet welds. The brackets were coated with a galvanized spray
paint. The brackets appeared to be in general accordance with the PET approved submittal. We understand that the
brackets will be painted with coal tar pitch after the anchor bold adhesive has cured and the anchor bolts have been
tightened.
Anchor Bolts
Upon arrival, we observed that the contractor had shifted the bracket locations vertically by about 3 to 12 inches and
drilled new anchor holes. The new anchor holes were drilled with a 13/16-inch bit in accordance with the manufacturer's
directions for the project specified Simpson Strong Tie AT-XP acrylic adhesive. We checked the expiration date of the
onsite AT-XP adhesive. The onsite adhesive was within the expiration dates, which ranged from February to March of
2023. The AT-XP adhesive tubes and the concrete substrate both ranged from about 42 to 45 degrees Fahrenheit. This is
within the manufacture's allowable installation and curing limits for AT-XP adhesive.
The project plans require a minimum anchor embedment depth of 5% inches. Measured anchor hole depths ranged from
4% to 6 inches in depth. The contractor indicated that they could not drill deeper due to refusal on rebar. We contacted
the project structural engineer Pacific Engineering Technologies (PET) and inquired if the reduced embedment depths
were adequate. PET indicated that the increased number of piles per abutment resulted in a reduced capacity per pile
and that a minimum anchor embedment of 4% inches was acceptable provided the average anchor embedment depth
per bracket was at least 5 inches. Based on our field measurements, the drilled anchor holes met the revised criteria. The
anchor holes met the manufactures minimum required anchor to anchor spacing and critical edge distance criteria.
We observed the contractor clean each anchor hole with a combination of compressed air and a nylon brush in accordance
with the manufacturer's directions. The contractor then applied Simpson AT-XP acrylic adhesive using the Simpson piston
plug system and %-inch diameter galvanized thread bar in general accordance with the manufacturer's recommendations
for horizontal installations for all 6 brackets.

We visited the project site at 8:00 am at the request of the contractor and on behalf of the owner to confirm that the
approved asphalt emulsion corrosion protection has been applied to the pile brackets and that the annular space between
the footing and the piles has been filled with grout. A summary of our observations, recommendations, and conclusions
is presented below.
Pile Brackets
Upon arrival, a representative from Waeco informed us that the anchor bolts for the pile brackets had been tightened
after the anchor adhesive had cured in accordance with the manufacturer's directions. We observed that all six pile
brackets and mounting bolts had been painted with Henry Asphalt Emulsion Sealer and Dampproffer in accordance with
