By: Ryan Larson, Senior Engineer
DATE: March 29, 2013
SUBJECT: EMWS Emergency Storm Pipe Repair 11 -19 -12 / 2013 Annual Small Drainage
Project No. 91241206, Contract No. 13 -036
Supplemental Agreement No. 1
ISSUE
Approve Supplemental Agreement No. 1 to Contract No. 13 -036 with KPG, Inc. for final design
services for the East Marginal Way South (EMWS) Emergency Storm Pipe Repair 11 -19 -12 Project.
BACKGROUND
On November 19, 2012, a large sinkhole was created by a break in a 30 -inch storm water line on
East Marginal Way South just south of S 124th St. The pipe conveys storm water flows from the east
fork of Riverton Creek, as well as local drainage in the area near Group Health. The pipe is
corrugated metal (CMP) and is approximately 10' deep. KPG performed preliminary engineering
under this contract for $39,403.95 to investigate the location and condition of the pipe as well as
recommend which segments should be replaced.
ANALYSIS
The preliminary investigation determined that the failing three segments of this system should be
replaced as soon as practical due to various deficiencies. These include: the pipe crosses between
public and private property, the pipe is located beneath one building, a power pole appears to be
driven through the pipe causing a backwater condition, and the pipe is made up of failing sections
of undersized CMP. Additional design considerations include a review of existing easements,
extensive potholing to determine the actual location of the pipe and other utilities, and conducting a
geotechnical investigation to determine soil and ground water conditions and the location of any
contaminated fill materials.
The EMWS Emergency Storm Pipe Repair 11 -19 -12 Project is not budgeted, but given the poor
condition of this pipe it is recommended that design and repairs take place as soon as possible and
that design and construction funding come from the 2013 Annual Small Drainage Program. The
2013 SDP will not fully fund EMWS, so we are proposing that other projects be delayed one year to
provide additional design and construction funding. The delayed projects include; the Lower
Duwamish Surface Water Conveyance, Christensen Rd Surface Water Pipe and East Marginal
Way S Outfalls.

Emergency Stormwater Pipe Repairs
Supplement No. 1 - Final Design
Scope of Work
March 26, 2013
PURPOSE:
This purpose of this supplement is to perform geotechnical review, utility potholing, right
of way and easement research, final design, and cost estimating for replacement of an
aging 36-inch stormwater pipe along E. Marginal Way S. between approximately 12500
and S 120th Place. A sink hole was discovered directly above the pipe in November of
2012 due to a localized pipe collapse. Spot repair of the pipe and limited video work
revealed that the pipe is in extremely poor condition and requires replacement. The
replacement pipe will be upsized to 48-inch to match other replaced segments along the
stream reach and reduce the likelihood of upstream flooding during heavy rainfall
events.
90% Design drawings and cost estimates will be prepared for the entire pipe reach from
the inlet to the existing 48-inch pipe just south of S 120th Street. Based on available
budget, it is anticipated that only a portion of the pipe replacement will be advanced to
final bid documents and construction. The remaining portion will be finalized for bid and
construction in the future.
This supplement supercedes and provides a credit for the remaining budget from the
original authorization. Due to poor pipe conditions encountered, an extensive review of
alternatives was not necessary to determine the preferred final design approach as
anticipated in the original contract authorization.

SCOPE OF WORK:
Task 1 — Management, Coordination & Administration
2.1 The estimated project duration is 4 months. The Consultant shall provide overall
project management including:
• Project staff management and coordination
• Subconsultant management and coordination
• Schedule and budget monitoring and reporting
Task 2 — Field Investigations
2.1 The Consultant shall coordinate geotechnical review to determine groundwater
depths, trenching recommendations, and other information for construction of the
new pipeline. Geotechnical review will be performed by Geo Design under
subcontract to the Consultant and will include the following work:
• Review available existing geotechnical, geological, and environmental reports
for the immediate area along the alignment and recent maintenance surveys
of the existing pipeline.
• Select/revise proposed boring locations and coordinate and manage the field
investigation, including obtaining a street-use right-of-way permit from the City
of Tukwila (City). A street-use right-of-way application is required along with
a proposed traffic control plan.
• Mark boring locations and request public utility locates. A separate trip to the
site will be necessary to mark the boring locations in order to get the utility
locates completed, to evaluate traffic control requirements, and to identify
which bus stops may be impacted or parking spots that will need to be closed
during the field work. The traffic control plan and identification of parking
spots or driveways that will need to be blocked off during the drilling and
anticipated work hours will be provided in the traffic control plan submitted
with the right-of-way permit application.
• Explore subsurface conditions by completing up to five soil borings as shown
and summarized on the attached Figure 1. The borings will be completed to
a depth of approximately 20 feet, or less if bedrock is encountered.
City of Tukwila KPG
EMW Storm Final Design Page 2 of 6 March 26, 2013

Information obtained from the borings will be the basis of
recommendations addressing utility trenches and dewatering criteria.
Drilling will be completed using hollow-stem auger drilling techniques, and
samples will be collected using the standard penetration tests for
correlation with soil engineering parameters. Samples will be collected at
2.5-foot intervals to the bottom of the boring. Our representative will
collect soil samples and maintain a log of the subsurface conditions
encountered.
We anticipate traffic control services, including one flagger, will be
required when working within the right-of-way and at some locations one
half or a driveway will need to be blocked off in order to access the drilling
locations and to re-route traffic around the equipment.
A separate site visit will be necessary in order to erect the no
parking barricades prior to performing the drilling. During this visit we will
also verify that there are no utility conflicts with the proposed locations.
We anticipate each boring can be drilled in approximately two hours, after
which the area will be cleared and parking can be opened.
The proposed drill rig is a trailer-mounted rig that will only occupy
one lane and that can be backed up off the curb to access locations in
planter areas.
• Complete laboratory analyses on disturbed soil samples obtained from the
explorations to assist in soil classification and evaluating engineering
parameters. Test may include up to
12 moisture content determinations and 4 grain size distribution tests.
• Complete analytical laboratory testing on up to five composite soil samples
obtained from the borings if cement kiln dust or some other chemical
contaminant is suspected. A suite of tests, including petroleum hydrocarbon
screening (WTPH-HCID), TCLP metals (RCRA 8), volatile organic
compounds (VOCs; U.S. Environmental Protection Agency [EPA] 8260), and
semi-volatile organic compounds (SVOCs; EPA 8270D), will be necessary to
characterize the soil, evaluate chemical hazards, and identify disposal
options.

• Prepare a report summarizing our findings, conclusions, and recommendation
related to the following:
• Subsurface soil and groundwater conditions and results of laboratory
testing
• Utility installation and excavation
• Maintenance structure and pipe support
• Dewatering
• Subgrade preparation below restored paved areas
• Fill material, compaction requirements, and geosynthetics
• Environmental Considerations to address impacted soil
2.2The Consultant shall prepare a potholing plan and coordinate field potholing of
utilities in the vicinity of the new pipe. Potholing will be performed by Bravo
Environmental Services under subcontract to the Consultant.
Task 3 — Survey and Right of Way
3.1 The Consultant shall perform additional topographic survey around the tavern
site and pick up all potholes and boring locations identified in Task 2. All
information will be incorporated into the project base maps.
3.2The Consultant shall obtain and review 9 title reports, review existing surveys,
perform necessary field ties, and perform necessary calculations to make a
determination and incorporate right of way and parcel lines into the project base
maps.
3.3The Consultant shall research, calculate and incorporate any existing drainage
easements into the project base maps based on title report information.
3.4The Consultant shall prepare legal descriptions and exhibits for new drainage
easements on up to 3 parcels based on the new pipe alignment. Easement
language will be provided by the City.
3.5The Consultant shall coordinate with affected property owners to obtain
necessary drainage easements. The budget assumes that easements will be
obtained on a mutual benefit basis and that appraisals and/or extensive
negotiations will not be required.
