SUBJECT: 2015 CBD Sanitary Sewer Rehabilitation Project
Project No. 91541201, Contract No. 15 -074
Construction Management Supplemental Agreement No.1
ISSUE
Approve Supplemental Agreement No.1 to Contract No. 15 -074 with RH2 Engineering, Inc. (RH2).
BACKGROUND
Consultant Contract No. 15 -074 with RH2 provided design engineering services for the 2015 Central Business
District (CBD) Sanitary Sewer Rehabilitation. Two separate construction projects were generated after the
design was completed; the 2015 Sanitary Sewer Manhole Rehabilitation Project and the 2015 CBD Sanitary
Sewer Rehabilitation Project. Supplemental Agreement No. 1 with RH2 will provide construction management
(CM) support for these two sanitary sewer construction projects. City Council awarded the 2015 Sanitary Sewer
Manhole Rehabilitation Project to Olson Brothers Pro -Vac, LLC, and the construction contract for the 2015 CBD
Sanitary Sewer Rehabilitation project was awarded to Michels Corporation at the November 2, 2015 Council
meeting.
DISCUSSION
To properly manage these two sanitary sewer construction projects, the City will need CM support during the
construction phase. Through this Supplement No. 1, RH2 will provide construction inspections, review of
material submittals and change order requests, and assist with monthly payments. RH2 staff has expertise in
construction inspection for sewer pipe relining and manhole construction and has performed the design work for
these two projects. Tukwila CM staff will still provide the majority of the CM work and the remaining share of
field inspections.
BUDGET SUMMARY
This Supplemental Agreement was carefully reviewed and is reasonable for cost and scope of work.

CITY OF TUKWILA CAPITAL PROJECT SUMMARY
2015 to 2020
PROJECT: CBD Sanitary Sewer Rehabilitation Project No. 91140203
DESCRIPTION:
The asbestos concrete pipe in the CBD (commercial business district) is approximately 45 years old and
becoming soft. Slip lining the pipe will reinforce the strength with little impact to roadways and minimal excavation.
JUSTIFICATION:
If the pipe collapses, the street will have to be excavated and the cost of the repairs will be significant. In the
last five years we have had two major pipe failures on Andover Park West.
STATUS:
A Public Works Trust Fund loan was successfully obtained in 2012 for construction.
MAINT. IMPACT:
Reduced maintenance and repair costs.
COMMENT:
The limits of the 2013 project is APW to APE from Minkler Blvd to S 180th St and will now include the repair
to the sewer under the railroad tracks.

remain in effect except as expressly modified by this supplement.
The changes to the agreement are described as follows:

and phone correspondence with City regarding scheduling the pipe segments with the
greatest criticality.

reduced scope project consistent with revised CIP determined in Task 1.
Approach:

I. PRESENTATIONS
11. BUSINESS AGENDA
A. Agreement: South 200th Street Bridge - Streamgage
Staff is seeking Council approval of a Water Resources Investigations Agreement with the
U.S. Department of the Interior for the South 200th Street Streamgage Project. The U.S.
Geological Survey (USGS) installed the gage in 2011 to provide real time river flow
monitoring in the lower reaches of the Green River. The annual monitoring cost for 2016 will
be $9,610.00. UNANIMOUS APPROVAL. FORWARD TO DECEMBER 7, 2015 REGULAR
CONSENT AGENDA.
B. Grant Application: Gilliam Creek Fish Barrier Removal Proiect
Staff is seeking Committee approval to submit an application to Puget Sound Partnership
for $30,000 in grant funding for the Gilliam Creek Fish Barrier Removal Project. This project,
which will construct a fish ladder and self - regulating tide gate, is a good candidate for the
program as it is one of WRIA 9's projects in the Salmon Habitat Plan. No City match is
required. UNANIMOUS COMMITTEE APPROVAL.
C. Project Completion: CBD Sanitary Sewer Rehabilitation
Staff is seeking Council approval of project completion and release of retainage to R.L. Alia
Company in the amount of $547,954.88 for the CBD Sanitary Sewer Rehabilitation Project.
This contract was issued in October 2014 to repair a collapsed sewer line and install a
manhole in Andover Park East, and was completed on August 21, 2015. Cost overruns
were due to additional pipe required to repair collapsed sewer near the railroad tracks and
a separate pipe collapse that occurred during construction. UNANIMOUS APPROVAL.
FORWARD TO DECEMBER 7, 2015 REGULAR CONSENT AGENDA.
D. Project Completion: 2015 Small Drainage Program
Staff is seeking Council approval of project completion and release of retainage to Green
River Construction, Inc. in the amount of $182,542.58 for the 2015 Small Drainage Program.
The project provided drainage improvements at three locations and was physically
completed on October 2, 2015. Overruns were mainly due to additional usage of quarry
spall for culvert slope stabilization. UNANIMOUS APPROVAL. FORWARD TO
DECEMBER 7, 2015 REGULAR CONSENT AGENDA.
E. Agreement Supplement: 2015 CBD Sanitary Sewer Rehabilitation
Staff is seeking Council approval of Supplemental Agreement No. 1 with RI-12 Engineering,
Inc. in the amount of $96,574.00 for construction management of the 2015 Sanitary Sewer
Manhole Rehabilitation Project and 2015 Sanitary Sewer Rehabilitation Project. This
Utilities Committee Minutes November 24, 2015 - Page 2
supplement if approved will provide construction management support for the two projects,
including inspections, material review, change order requests, and payment assistance.
UNANIMOUS APPROVAL. FORWARD TO DECEMBER 7, 2015 REGULAR CONSENT
AGENDA.
F. Consultant Selection: Tukwila International Boulevard Redevelopment Project
Staff is seeking Council approval of a construction management contract with AKANA in the
amount of $72,646.00 for the Tukwila International Boulevard Redevelopment Project. This
project will demolish the Sam's Smoke Shop building along with the Great Bear, Boulevard,
and Spruce Motels. The proposed scope of work is based on the number of expected
working days and is independent of the decision the Council makes regarding the Travelers
Choice Motel. That property is currently being evaluated as a potential site for art use in
partnership with 4Culture, and a decision is expected in December. UNANIMOUS
APPROVAL. FORWARD TO DECEMBER 7, 2015 REGULAR CONSENT AGENDA.
G. Water, Sewer, and Surface Water Rates for 2016
Staff is seeking Council approval of a resolution adopting a new Public Works fee schedule
to update water, sewer, and surface water rates for 2016. Committee packets include rate
comparison charts for neighboring cities for each type.
Water: After analyzing the needs of the water enterprise fund, staff is proposing no increase
for single family or multifamily residential customers and a 5% increase for
commercial/industrial.
Sewer: Staff is proposing no increase for residential customers and a 5% increase for
commercial/industrial.
Surface Water: Staff is proposing a 15% increase for residential and commercial customers.
Committee members asked clarifying questions. Committee Chair Robertson requested a
2016 work plan item to discuss financing of large projects in greater detail, including
information on utility-specific local improvement districts. The Committee forwarded the
resolution to the consent agenda but asked that Public Works staff be in attendance to
address any questions that arise. UNANIMOUS APPROVAL. FORWARD TO DECEMBER
7, 2015 REGULAR CONSENT AGENDA.
