PARK AVENUE N EXTENSION — FINAL DESIGN PHASE
Agreement with Perteet Inc. January 8, 2018
Explorations and Field Work
• Revise Geotechnical Work Plan Memo: HWA will revise the Geotechnical
Work Plan Memorandum to reflect the additional explorations consisting
of drilling two 60-foot-deep geotechnical borings and installing 2-inch
diameter ground water monitoring piezometers in each boring. The
boring locations will be located within or as close as possible to the
proposed jacking and receiving pits. This work plan will be submitted to
the City for review and approval. The work plan will detail the type,
location, and extent of proposed field explorations along with logistics
necessary to perform the work such as traffic control plans and staging
areas. The work plans will also be used for utility locating clearances and
for permitting that may be necessary to access the exploration locations.
The CITY will acquire and provide any required permits or right of entries
at no cost to HWA. Locating borings in the Boeing area is anticipated to
be challenging and will require HWA to coordinate with the Boeing
Company. In addition to revising the Geotechnical Work Plan Memo,
HWA will meet in the field with Boeing representatives to identify boring
locations.
• Conduct Additional Explorations: HWA original scope and budget
included drilling six, 20-30-foot-deep borings in support of the roadway
project. These borings where assumed to be drilled with limited access
equipment. 4 actual borings locations were identified once the project
condensed. Three of these borings are proposed within the Boeing right
of way to support the roadway design. The cost to drill these borings is
covered by the original scope and budget.
HWA will conduct two (2) additional geotechnical borings to assess the
subsurface soil conditions at the location of the proposed jacking and

receiving pits. One boring will be located within PSE property and one
boring will be located within the triangular gore area on 757th Avenue
Boeing access road. The boring conducted within the pavement areas
accessing Boeing will be drilled during the day-time hours of 9AM to 3PM
with appropriate traffic control measures. Each boring will be drilled to a
depth of 60 feet below ground surface. Traffic control to consist of Arrow
Board Mounted Attenuator Truck behind coned off work area for both
coring and pavement patching by subcontractor. Flaggers may be utilized
as needed (assume 1 day of flaggers). There will be separate mobilizations
for each of these borings.
A 2-inch ground water monitoring piezometer will be installed in each
boring to monitor ground water fluctuations. A road grade flush-mounted
steel monitoring well monument will be installed at the location of each
monitoring well. Data logging transducers will be installed in the well to
measure water levels over a period of one (1) year. Upon completion of
design, the monitoring well will be decommissioned by the Contractor in
accordance with the DOE requirements.
As the addition of these two borings and associated wells will reduced the
already approved roadway borings from six to three, a drilling credit of
$4,000 has been assumed in calculation of the required budget
supplement.
Each geotechnical boring will be logged by an HWA geotechnical engineer
or engineering geologist. Each boring conducted through the pavement
will be patched with quick drying concrete upon completion of the boring.
• Generate Boring Logs and Assign Laboratory Testing: HWA will prepare
summary boring logs and perform laboratory testing to evaluate relevant
physical properties at the location of the proposed jacking and receiving

pits. Laboratory testing would include moisture content, hydrometers,
grain-size distribution, and Atterberg Limits.
• Slug Testing and Data Reduction: HWA shall conduct a slug test at the
location of each monitoring well. Slug test will consist of quickly adding fresh
water to a ground water well, and monitoring the changes to hydraulic head
continually, to determine the near-well hydraulic transmissivity. The slug test
conducted within the pavement areas accessing Boeing will be performed during
the day-time hours of 9AM to 3PM with appropriate traffic control measures.
Traffic control will be limited to appropriate signage and closure of a limited
coned off work area at the location of each monitoring well within PSE property
and the triangular gore area on 757th Avenue Boeing access road. A team of two
hydrogeologist/geotechnical engineer from HWA shall conduct the slug testing
and data reduction. This data will be used to provide dewatering
recommendations to prospective contractors.
Additional Geotechnical Design Services:
• Providing Temporary Shoring Recommendation: Based on the borings
and the laboratory test results of selected samples, HWA will provide
temporary shoring recommendations and lateral earth pressure diagrams
for the jacking and receiving pits.
• Generating Dewatering Recommendation: HWA will conduct theoretical
hydraulic conductivity analyses. The results of slug testing in addition to
hydraulic conductivity analyses will be used to developing dewatering
recommendation at the location of jacking and receiving pits.
• Providing Jack and Bore Recommendation: Based on the soils
encountered along the alignment, HWA will determine the Site Class for
seismic design. The design spectral acceleration parameters will then be

selected in accordance with the AASHTO Specifications for Road and
Bridge.
• HWA QA/QC: HWA will have all additional design calculations and
recommendations reviewed by a senior principal prior to distribution to
the design team or the City.
• Update Draft Geotechnical Engineering Report: HWA will update the
draft geotechnical engineering report with additional analyses and
recommendations for the proposed sanitary sewer extension. This report
will contain the results of the geotechnical engineering investigation,
including description of surface and subsurface conditions; a site plan
showing exploration locations and other pertinent features; summary
boring logs; and laboratory test results. The report will provide
geotechnical recommendations for each of the proposed improvements.
ASSUMPTIONS
• The geotechnical explorations proposed herein will not be used to assess site
environmental conditions. However, visual or olfactory observations regarding
potential contamination will be noted. Analysis, testing, storage, and handling
of potentially contaminated soil and ground water (either sampled or spoils
from drilling) are beyond this scope of services. If contaminated soils and/or
ground water are encountered, the material will be properly contained on-site
for disposal as mutually agreed upon without additional cost to HWA.
• All drilling spoils and related debris from the Boeing right of way will be
drummed on site and left on site for Boeing to dispose of per their protocol.
All drilling spoils and related debris from the PSE right of way will be
drummed on site and left on site for PSE to dispose of per their protocol.
• HWA will be responsible for all post drilling clean up.
