INFORMATIONAL MEMORANDUM
TO: Transportation and Infrastructure Committee
FROM: Hari Ponnekanti, Interim Public Works Director
BY: Cyndy Knighton, Senior Program Manager
CC: Mayor Ekberg
DATE: October 2, 2020
SUBJECT: West Valley Highway (I-405 – Strander Boulevard)
Project No. 99310410, Contract No. 19-095
Supplemental Agreement No. 1
ISSUE
Approve Supplemental Agreement No. 1 with TranTech Engineering for the design of the West
Valley Highway (I-405 – Strander Boulevard) Project.
BACKGROUND
Since September 2019, TranTech Engineering has been working on the design of the West
Valley Highway project, which also includes improvements along Longacres Way from West
Valley Highway to the Tukwila Station. The design is currently at the 60% level and is
proceeding toward final design. The project has funding for the design and construction from
three grant sources: Transportation Improvement Board, CMAQ, and System Access Funds.
The project is also on the Traffic Impact Fee list.
DISCUSSION
As the design has progressed, needs for additional design funds were discovered. The attached
Supplemental Agreement No. 1 Summary details the specific tasks that require additional
funding to complete the design. With the federal CMAQ grant funds and the fact that the project
is on a State Highway, additional tasks are required by WSDOT in order to gain their approval.
These tasks include the Noise Assessment and Collision Analysis Report. Additional
geotechnical exploration is necessary with the design change from a wall to a “pedestrian
bridge” for the sidewalk over the Seattle Public Utilities 60-inch watermain. Additional costs are
needed to cover costs not included in the original scope of work for design but will result in
significant savings for the project’s construction.
FINANCIAL IMPACT
Supplement No. 1 is for an increase of $148,325 for a new total contract amount of $680,263.
Right-of-way acquisition costs are not expected with this project, so the $100k budgeted for
Land will be reallocated to Design. The remaining $32,163 will come from reallocation of funds
from the construction phase.
RECOMMENDATION
Council is being asked to approve Supplemental Agreement No. 1 to Contract No. 19-095 for
$148,325, for a total contract amount of $680,263, with TranTech Engineering and consider this
item at the October 19, 2020 Consent Agenda Regular Meeting.

4. Geotechnical Engineering-Landau Associates (LAI)
LAI will provide geotechnical engineering services to support design of the bridge and signal standard
foundations for the mid-block pedestrian crossing. Work elements include:
Prior to initiating fieldwork, LAI will coordinate the clearance of underground utilities at the proposed
exploration locations. LAI will mark the locations in the field and contact the Washington Utilities
Coordinating Council's "One-Call" locating service. LAI will also hire a private utility-locating service to
identify conductible utilities located outside of public easements.
LAI will explore subsurface soil and groundwater conditions at the proposed bridge abutments by
advancing two borings approximately 30 feet (ft) below ground surface (bgs). The explorations will be
coordinated and monitored by LAI personnel, who will also collect representative soil samples and
maintain a detailed log of the subsurface conditions observed. LAI will subcontract the drill rig and
operator. Upon completion of fieldwork, the boreholes will be decommissioned in accordance with
the requirements in Washington Administrative Code 173-160.
LAI will perform geotechnical laboratory testing on select samples obtained from the explorations. LAI
anticipates that the testing program will include four natural moisture content determinations and
four grain size-distribution analyses or Atterberg limits determinations. Samples will be retained for
30 days after submittal of the final technical memorandum. Samples will then be discarded, unless
other arrangements are made.
LAI will complete engineering analyses and develop geotechnical conclusions and recommendations
to support design of the bridge and signal standard foundation.
LAI will revise its November 2019 technical memorandum to include:
An updated site plan showing the locations of the additional subsurface explorations.
Summary boring logs and laboratory test results.
Additional discussion of near-surface soil and groundwater conditions along the project alignment.
Brief discussion of liquefaction susceptibility and estimated liquefaction-induced settlement.
Updated recommendations for earthwork and site preparation (if necessary).
Geotechnical design recommendations for the new signal standard foundations.
Recommendations for shallow foundation support of the bridge, including criteria for foundation
subgrade preparation, engineering parameters, nominal bearing pressure, estimated foundation
settlement, and lateral earth pressures acting against wing walls
Assumptions
LAI will be provided with a project base map in AutoCAD® format.
Fieldwork can be performed during standard business hours (i.e., no weekend, holiday, or nighttime
drilling will be required).
The exploration locations are accessible to a track-mounted, limited-access drill rig. Trees or other
vegetation obscuring the exploration locations will be removed by others.
23
West Valley Highway (Strander Blvd to I-405) 4
During the field investigation, care will be taken to limit surface disturbance; where disturbance is
unavoidable.

Transportation (WSDOT) right-of-way; a WSDOT general permit will not be required.
Upon completion of fieldwork, drill cuttings will be spread discreetly in the vicinity of the exploration
locations.
Traffic control will not be required.
Findings of the current study will be supplemented with subsurface data previously collected in the
vicinity of the Tukwila Urban Center Pedestrian Bridge. These data will be used to evaluate soil
parameters and seismic behavior of strata more than 30 ft bgs.
Native site soils will provide suitable support for a bridge built on shallow foundations, under static
conditions.
The bridge will not be designed to resist the effects of soil liquefaction.
If needed, pavement design will be completed at a later date under separate scope and budget.
If needed, pilot infiltration tests will be completed at a later date under separate scope and budget.
Chemical analysis will not be performed on soil samples obtained from the borings.
